Edit: Found that the theme options panel set up (using a class) was causing the problem. Still not sure why - would still love know how to find out what the problem is - e.g. is it a JS or PHP issue. Going to try a different method of creating the theme options panel to see if it fixes the problem. I am able to add extra TinyMCE buttons that are bundled (e.g. HR, anchor), but am unable to add custom plugins of my own. I have also noticed that other plugins (WP-Table Reloaded, cForms, TinyMCE Advanced) are also unable to load custom plugins. Disabling all other plugins does not solve the issue. What could be causing this, and/or how can I find the problem? When viewing source of an edit post screen, mceInit options do not list any plugins besides those defined as WP default. Altering the $initArray does work, but of course does not point to the correct location of added plugins. | You should read this: http://codex.wordpress.org/TinyMCE_Custom_Buttons It's pretty straightforward if you already know how to program a TinyMCE plugin (which it sounds like you do). | How can I troubleshoot why TinyMCE won't load custom plugins in the visual editor? | wordpress |
I have been working on using featured image to create a list of items on the right column here: http://www.julianamaeberger.com/soma/news/ The current featured image is now being given a class of "highlighted" so that you can tell which image is related to the post. I now need to move that li class="highlighted" to the top of the list so that it's always visible. Is jquery sortable the best option here? Thanks for any help in the right direction. | Can't you do this in HTML? So instead of printing everything in your loop, append it to a string that you print in the end. That way you can keep special stuff apart. I assume this is a follow-up question to your previous question about featured images, so I will use stackexchange-url ("the code from my answer there") as an example. <code> <?php $testimonials = get_posts( array( 'category_name' => 'testimonial', 'numberposts' => -1, 'order' => 'DESC' ) ); $highlighted_testimonial_thumbnail = ''; $other_testimonial_thumbnails = ''; foreach ( $testimonials as $testimonial ) { if ( $testimonial->ID == $current_testimonial_id ) { $highlighted_testimonial_thumbnail = '<li class="highlighted">' . get_the_post_thumbnail( $testimonial->ID, 'nav' ) . '</li>'; } else { $other_testimonial_thumbnails .= '<li>' . get_the_post_thumbnail( $testimonial->ID, 'nav' ) . '</li>'; } } echo '<ul class="portfolio">'; echo $highlighted_testimonial_thumbnail; echo $other_testimonial_thumbnails; echo '</ul>'; </code> Or more generic: instead of: <code> foreach ( $array_of_stuff as $stuff ) { echo $stuff } </code> Do it like this: <code> $output = ''; $featured_output = ''; foreach ( $array_of_stuff as $stuff ) { if ( is_featured( $stuff ) ) { $featured_output = $stuff; } else { $output .= $stuff; } } echo $featured_output; echo $output; </code> Almost all functions in WordPress that echo something have an equivalent that doesn't echo but just returns it. <code> get_the_content() </code> vs <code> the_content() </code> for example. | How to move featured image to the top of the list? | wordpress |
I am registering sidebars automatically for each category (a separate widget space per category). The technique I'm using is here . In the admin side I have an options page where I need to display a dropdown of all registered sidebars... Is there are way to dynamically get this list of registered sidebars? since they're being registered in functions.php I assume they're in memory, not in the database. I could keep track of the sidebars I register in some global variable, but just in case plugins register their own sidebars, I'd like to account for them too. I'll dig through the core if I have to, but thought someone might know off-hand:) Thanks | Hmm... I'm not sure if this is the best way to do it but it's simple: I looked in register_sidebar() and found that new sidebars are simply tacked onto an array: $wp_registered_sidebars And I guess that's that. If they ever change the name of the variable, I guess I'd be screwed. | Get list of all registered sidebars | wordpress |
So I have a custom type called "vendors" and two custom taxonomies for it. One is "state" and the other is "type". I am trying to list all the vendors from a certain state on one page. I'm using the file called "taxonomy-state.php" which works perfectly. It displays all the vendors in the state. Now what I want to do is specify the types of vendors in order. So the page will look something like this: Vendors in "STATE": Vendor Type #1: Vendor #1 Vendor #2 Vendor #3 Vendor Type #2: Vendor #1 Vendor #2 Vendor #3 I got it to display vendors by state. But I need to display them in the above layout. I have an idea of how to do it. But I need to be able to make a query that can get a vendor from a certain state and certain vendor type. Thanks in advanced, Alain | Hopefully someone else will flesh out this answer, I don't have the time to write out a full solution right now... If you're using WordPress 3.1, look at the <code> tax_query </code> parameter that you can pass to <code> query_posts </code> . It can handle multiple taxonomies and relationships between them. Otto's post WordPress 3.1: Advanced Taxonomy Queries is the best explanation I've seen of what tax queries can do, and how to use them... In older versions of WP, you're stuck using a plugin like this one , or rolling your own fairly complex SQL queries. | Query posts with double taxonomy | wordpress |
Is there a way to use regular categories with custom post types? It seems like there is better functionality and options with regular categories (such as permalink options, etc.). | No problem, the categories and tags are also registered as taxonomies that you can pass to the <code> taxonomies </code> argument when you call <code> register_post_type() </code> . Categories are <code> category </code> and tags are <code> post_tag </code> . You can also do this later with <code> register_taxonomy_for_object_type() </code> : <code> add_action( 'init', 'wpse6098_init', 100 ); // 100 so the post type has been registered function wpse6098_init() { register_taxonomy_for_object_type( 'category', 'your_custom_post_type' ); } </code> | Is there a way to use regular categories with custom post types? | wordpress |
If I'm using a custom post type for a Movie or a TV show episode, I may use a taxonomy for "actors" and assign all the actors related to the work to it, but I'm not sure how, besides of that, I can also add the character the actor is playing in said work . The characters themselves may or may be not a taxonomy, as sometimes one also needs extra space for adding notes, like "John Doe (voice)" or "John Smith (via stock footage). I can figure something like a metabox with columns for each thing, yet I'm not sure how to make it harmonious (or do it at all). | You could simply use the "pods"-plugin (for WordPress) from Matt Gibs and Scott Kingsley Clark. It's exactly what you searching for. Take a look at the doku and look specificaly at "pick columns". Aside from that it has a nice and ajax driven interface and builds it's database tables next to wordpress and doesn't make use of the default tables (there's nothing wrong with adding new tables). It really converts Wordpress to a full CMS system. I tried it in some projects and was easily able to achieve everything i wanted. A big plus is the irc-chat where you find a nice, friendly and helpful croud and the developers. An here goes another plus: When you feel comfortable with pods, then add pods UI to your weaponary. :) Wish you best! | Add additional data to a specific taxonomy term when used in a post | wordpress |

Anyone know of a function that can do this? | Every string goes through <code> translate() </code> , which uses the <code> gettext </code> filter.

Basically, I'd like to create a category permalink like example.com/books/adventure without having to make adventure a child-category because it will apply to other categories as well. So the end result is: example.com/books/adventure example.com/movies/adventure example.com/toys/adventure The order is based on the two parent categories, with "items" going first, and "genre" going second. And you could also search the categories separately to see all of the books, or all of the adventure items. How can I do this? Thanks! | David, welcome to wordpress answers. The answer is: Switch to some other platform. Wordpress can not with what's currently in core produce such a result easily. Technically spoken it's possible, but folks hate me here to say how (well Apache + PHP) in concrete, so I don't tell it because I fear the negative karma this give on this site. Just switch to something else if you seriously want to do such stuff and more. Like symfony2 with a database layer. After about one to three month as a single developer you can achieve much more then you can imagine with wordpress. And the best thing is: You can even add a wordpress blog later on. ;) | How can I create a permalink with two categories, with the order based on the parent category? | wordpress |
is it possible to bring custom taxonomies to permalink? currently my permalink is looking something like this <code> /%postname%/%category% </code> but i also want to add custom taxonomies to my permalink so it should look something like this <code> /%postname%/%category%/%location%/%mba_courses% </code> is this possible? the solution to this answer i found, i googled and i found this code, which works perfetc for me <code> add_filter('post_link', 'mba_courses_permalink', 10, 3); add_filter('post_type_link', 'mba_courses_permalink', 10, 3); function mba_courses_permalink($permalink, $post_id, $leavename) { if (strpos($permalink, '%mba_courses%') === FALSE) return $permalink; // Get post $post = get_post($post_id); if (!$post) return $permalink; // Get taxonomy terms $terms = wp_get_object_terms($post->ID, 'mba_courses'); if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0])) $taxonomy_slug = $terms[0]->slug; else $taxonomy_slug = 'mba_courses'; return str_replace('%mba_courses%', $taxonomy_slug, $permalink); } </code> but now i have one more problem, when i google my website i get the old url structure link, when i click on that i get 404 error, where as the post is still inside the website, just the url has changed, so how can i make the old url to direct it to new url i mean if clicking on the old url and instead of redirecting to 404 page, can it redirect to the actual post where i have the new url? is this possible? | What you're looking for is a 301 redirect. I use two plugins to catch do this. One notify's me of 404 errors ( http://wordpress.org/extend/plugins/404-notifier/ ) and the other makes writing the 301 redirects easy ( http://wordpress.org/extend/plugins/simple-301-redirects/ ). You could also write the 301 redirects in your .htaccess file and dig through the server logs to find the 404 notices. Long term you just need to wait for Google to crawl the site and find the new link structure. If other people are linking to your site from other blogs you can try and get them to fix their links but it's unlikely that you'll be able to get many people to do that. | custom taxonomies on permalink | wordpress |
I am new to WordPress, and I need to make some quick changes. How can I find the Page that is referenced by a permalink: e.g. for www.example.com/mypermalink how can I locate the actual WP Page so I can find it either in the file system or in the WP Pages list? | Addressing both your original question and the question implied by your comment ... Finding the page ID Every post and page within WordPress is given an ID. By default, WordPress uses the ID in the link structure: http://www.example.com/?page=ID or http://www.example.com/?p=ID (for posts). You can change this to a more user-friendly structure called "pretty permalinks" that will use the page slug in the URL instead: http://www.example.com/my-page-slug. In practice, though, these permalinks can become very long. This is bad for certain situations (i.e. posting to Twitter), so WordPress retains the shorter ID-based URLs as "shortlinks." You can figure out the shortlink for a particular post or page by navigating to that page, right-clicking, and selecting "view source." Then look through the source for a specific section of meta tags: <code> <meta name="generator" content="WordPress 3.0.3" /> <link rel='shortlink' href='http://example.com/?p=2' /> </code> This "shortlink" tag tells you that you're looking for post #2. Finding the page in WordPress admin You've already discovered the easiest way to find a post or page - just search for the page slug when you're in the admin. This will find it almost every time, or at least give you a small list of possibilities. Another way is to use the ID you discovered above to jump straight to the post/page edit screen. Every post or page edit screen uses the following URL structure: http://example.com/wp-admin/post.php?post= ID &action=edit Just substitute the ID you discovered above for ID in the URL and you'll be taken to the post/page edit screen for that content. Template Files Page templates are defined by your theme. They'll all be located somewhere in the <code> /wp-content/themes/YOUR-THEME/ </code> folder. The name of the page template (which you saw on the post edit screen) might give you a hint as to which file you're looking for, but I can't guarantee it. Just know that all page template files will begin with the following code: <code> <?php /* Template Name: PAGE TEMPLATE NAME */ ?> </code> So if you have more than one template file defined by your theme, looking for this tag will help you identify the specific one you'll need to edit. This template will define the HTML and PHP code used by pages that specifically call out that particular template. | How can I reverse engineer a Permalink to Find the Page? | wordpress |
I'm having a bit of a brain fart on this one. I'm working on some code that resembles a custom search form. The custom search form, is a mixture of checkboxes as well as some drop downs. All of the fields which are being searched for are also custom fields. The custom fields were entered through a custom write panel. Some of the fields are single values others are serialized fields. The current code works, but i'm not sure if should be taking another approach, i'm not looking for anyone to write code for me. I'm just looking for some ideas on how this could be better. <code> $city = $_REQUEST['sCity']; $activity = $_REQUEST['sActivity'][0]; $riverSegment = $_REQUEST['sRiverSegment']; $topicOfInterest = $_REQUEST['sTopicOfInterest'][0]; $querystr = " SELECT DISTINCT wp_posts.* FROM wp_posts, wp_postmeta WHERE ( wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = 'city' AND wp_postmeta.meta_value = '$city' ) OR ( wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = 'riverSegment' AND wp_postmeta.meta_value = '$riverSegment' ) OR ( wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = 'topicOfInterest' AND wp_postmeta.meta_value LIKE '%$topicOfInterest%' ) OR ( wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = 'activity' AND wp_postmeta.meta_value LIKE '%$activity%' ) AND wp_posts.post_status = 'publish' AND wp_posts.post_type = 'sites' ORDER BY wp_posts.post_date DESC"; </code> I feel like the above sample is flawed because if the first condition finds a match it will ignore the rest of the conditions. Side Note: If i'm working with $wpdb-> get_results(); should i still be escaping the user input to keep it clean? | This doesn't seem especially complex, but does seem bulky and prone to errors. As I answered couple of times on similar issues - if this isn't time critical then wait for WP 3.1 because it will have major improvements for querying by custom fields.

I made a custom post type and a custom taxonomy, but I have a problem. When I access the url <code> http://www.ithemes.co.kr/?shopcat=galaxy-s </code> , it works well. But when I access the url <code> http://www.ithemes.co.kr/?shopcat=5 </code> , it returns a 404 page. <code> galaxy-s </code> is the taxonomy term slug, but I want to access it by <code> term_id </code> , like you can with a category: <code> cat=1 </code> . I prefer <code> cat=1 </code> . What can I do? | This is not supported by default, but you can convert the numeric terms back to slugs with the <code> pre_get_posts </code> hook. I tested this with WP 3.0.1, but in 3.1 the taxonomy query handling changed, so I don't know whether this will work by default or if there is a better way to do it. <code> add_action( 'pre_get_posts', 'wpse6066_pre_get_posts' ); function wpse6066_pre_get_posts( &$wp_query ) { if ( $wp_query->is_tax ) { if ( is_numeric( $wp_query->get( 'term' ) ) ) { // Convert numberic terms to term slugs $term = get_term_by( 'term_id', $wp_query->get( 'term' ), $wp_query->get( 'taxonomy' ) ); if ( $term ) { $wp_query->set( 'term', $term->slug ); } } } } </code> Bizarre that you prefer the numeric version, many would choose the term slug for SEO reasons. | Query custom taxonomy by term id? | wordpress |
I'll try to make this as clear as possible. I'm am trying to figure out a few things to clean up the permalinks on a large website project. We're using custom post types and ~200+ custom categories (we chose this because you can really add a lot of custom field spaces and data easily with the new custom post types). We need our permalinks to look like this: example.com/books/adventure/post-name where "books" and "adventure" are both categories, but we would prefer "books" came first. We would create adventure as a sub-category of books, but we use this same category for adventure movies, adventure games, etc. So a large site with books, movies, games, etc. where a person first chooses one of those categories and then drills down deeper to adventure, romance, kids, etc. Right now, we have: example.com/main-category/books example.com/sub-category/adventure example.com/product/post-name Basically I need to: Remove the slugs from the custom type categories (i.e. main-category & sub-category) Make the "sub-category" appear after the "main-category" for the permalinks for sub-category pages. Create a new dynamic base category for the custom posts, which reflects the categories it's in (/books/adventures/post-name). Do this as simply and clean as possible, without a lot of plugins or things that may cause trouble down the line. OR...if you have a much better way to do this, I'm open to any suggestions. I know that we can use a Wordpress Network install instead of main-categories, but with 50-100+ of them, that is not feasible for us. | There is no such thing as a "dual category permalink" in wordpress, so you might be looking for custom rewrite rules (Wordpress.org Forums) and let deal your own code with the URL design as you need it then. | Remove slug from Custom Category Permalink + dual-category permalinks | wordpress |
I am starting a new wordpress blog, and no longer updating an old one. The old one still gets 400-500 hits a day, so I would like to keep it up for archival purposes, as people still link to its posts. Obviously there is the problem that wordpress and plugins will be updated, and I have no desire to maintain it. How can I lock the installation of wordpress down so I don't need to maintain it? I have seen someone suggest making a static version, which sounds like alot of work. A more reasonable solution I thought of was to disable write access to the database at the database user level. I'm fine with disabling comments from now on. Feel free to share any thoughts or comments on this. Thanks in advance. | With a dynamic CMS like WordPress, there is no real way to "lock it down." As the web evolves, formerly unknown security holes are discovered and patched in new versions. In reality, unless you're always running the latest version of WordPress (currently 3.0.4), your site is in some way vulnerable. If you don't intend to ever update it again, creating a static version is the best and safest option - not "crazy talk. A strong possibility is to use a caching plug-in and set the cache to never expire. The plug-in will automatically create static versions of your pages as they're needed. Your links will still work, and people will be directed to the static HTML versions of each post and page rather than the dynamic, database generated ones. By generating a static version, you won't need to worry about database updates, WordPress updates, plug-in upgrades, or new versions of themes. It becomes maintenance-free, but is also "frozen" in the sense that comments won't work and you can't add new content ... which is probably fine in this case. Another alternative is to keep things dynamic and outsource the task of updating your site. Have someone like WordPress.com host the site and point all of your links to that version of the site. The hosted service (particularly that one) will always have the latest security patches without any intervention from you. | How can I lock down an old wordpress install I don't intend to update? | wordpress |
I want to write a simple plugin. For every time a page is viewed, it will write to the MySQL database. Then, if the current hour is odd, it will set a PHP variable of $is_odd to true; <code> <?php require_once('library-of-functions-to-support-this-plugin.php'); function_to_write_to_mysql_db(); $is_odd = false; if(current_hour_odd()) { $is_odd=true; } $is_odd_json = json_encode($is_odd); ?> </code> Then, it should embed the following JavaScript (note: I've already modified the theme's templates to put an on each page): <code> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> var odd = <?php echo $is_odd_json; ?>; if(odd) { $("#OddElement").html('Odd!'); } </script> </code> So basically, I have no idea where to put these code snippets.

I think there used to be an out-dated plugin to do this. Is there any way to do this easily with just a little code? We prefer not to rely on a plugin since that makes us dependent on the developer to keep it up-to-date.

I have a few custom thumbnail sizes and obviously one of them is used in the set_post_thumbnail_size, what directly affects the interface in the admin area. What I'm looking to do is to intercept which admin page (for post-type) I'm in and set a different size in the above function, so basically I'd like to have that: <code> function setup_the_theme() { add_theme_support( 'post-thumbnails' ); if ($post_type == 'type_A'){ set_post_thumbnail_size( 298, 167, true ); //portrait } else { set_post_thumbnail_size( 192, 108, true ); //landscape } add_image_size( 'top_articles', 298, 167, true ); //portrait add_image_size( 'article_thumb', 203, 114, true ); //portrait add_image_size( 'featured_articles', 60, 200, true ); //landscape } add_action( 'after_setup_theme', 'setup_the_theme' ); </code> I suspect its too early in the cycle to know which post type i'm editing. | Simpler way to figure out the post type of the item (which you are editing) and uploading media to: <code> $type = get_post_type($_REQUEST['post_id']); </code> As has been noted, the media upload iframe that is shown in the lightbox overlay when you try to upload something doesn't indicate the parent post that new upload will be attached to. But the <code> $_REQUEST </code> is still active from the edit window, and still contains the post_id of the item you're editing - so just query the type for that id... You can use this technique in various hooks and filters - I've used the <code> intermediate_image_sizes </code> filter for image processing before, but not for this particular problem, but it should work there too... | change set_post_thumbnail_size according to post type admin page | wordpress |
I am using a WordPress plugin called MyReview but I want some changes to it. That plugin has feature to review posts, where users will come and give star ratings to the post according to categories, but in that plugin a user can give star rating to a post to as many times as the user wants, which I dont want, what I want is a user can give star rating to a post just a single time, for that purpose I had words with the author of the plugin, and he suggested me something like this, Query the comments table for any comments by the same email ID, check if there are any attached ratings, if there are, don't accept the ratings. All these changes would go in myrp-save.php. If you know PHP and are comfortable working with phpMyAdmin to understand the database tables, it would not be difficult to do. <code> SELECT id FROM myrp_ratings as rat, wp_comments as com WHERE com.comment_ID=rat.comment_id AND com.comment_author_email='whatever@whatever.com' AND rat.value!='0' AND rat.value!='1' LIMIT 1 </code> How can I put this line in that plugin file which is <code> myrp-save.php </code> ?

I'm setting post_parent to the parent post ID and the post_type needs to be "attachment". But!

So when settings the post_name to the same I'm getting all sub pages on one page when visiting /post/info/ and /post2/info/. Anyone knows if it's possible to accomplish this? | Hi @jonasl: I asked a clarifying question but I'm going to go ahead and at least start to answer. The function in WordPress core that controls post slugs and adds numbers to them in order to force them to be unique is <code> wp_unique_post_slug() </code> . In WordPress 3.0.3 you can find it on line 2530 in <code> /wp-includes/post.php </code> . I've copied it in full below for your review. You'll note it says "Attachment slugs must be unique across all types" so if your children are <code> post_type='attachments' </code> then this is what is forcing them to be unique. In addition you'll note that the post types must have <code> 'hierarchical'=>true </code> or it will force them to be unique across all posts. <code> function wp_unique_post_slug( $slug, $post_ID, $post_status, $post_type, $post_parent ) { if ( in_array( $post_status, array( 'draft', 'pending', 'auto-draft' ) ) ) return $slug; global $wpdb, $wp_rewrite; $feeds = $wp_rewrite->feeds; if ( ! is_array( $feeds ) ) $feeds = array(); $hierarchical_post_types = get_post_types( array('hierarchical' => true) ); if ( 'attachment' == $post_type ) { // Attachment slugs must be unique across all types. $check_sql = "SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND ID != %d LIMIT 1"; $post_name_check = $wpdb->get_var( $wpdb->prepare( $check_sql, $slug, $post_ID ) ); if ( $post_name_check || in_array( $slug, $feeds ) ) { $suffix = 2; do { $alt_post_name = substr ($slug, 0, 200 - ( strlen( $suffix ) + 1 ) ) .

If you can't do that I might be able to suggest a have to fake it during insert of the post but I can't promise doing so will not cause other posts in WordPress to break. If you are using attachments and need this maybe you can explain more what you are trying to accomplish so that maybe we can suggest an alternative. | Sub posts and non unique post_name | wordpress |
wp_list_pages seems to print out menus ok, but is there a way to alter the functionality so that i can display the menu in two colors..? So, if the titles of 3 actual pages are: <code> Big Cinema * Monaco Theatre * San Franciso Sport * Berlin </code> (each page really has two titles, the asterisk used to separate them. another character could be used..... or is there a way of entering two titles?) When these are displayed you would get the two titles for each page displayed a little differently: Big Cinema Monaco Theatre San Franciso Sport Berlin (the italics above representing blue, the rest green) Is there a way to alter the wp_list_pages behaviour, or is there a better technique to do this? | Hi @cannyboy: Unless I misunderstand, I think what you need is to use <code> 'the_title' </code> filter. If you simplly enter "Title 1 * Title2" into your title field, this code I've written for this hook should wrap your Title2 in a <code> <span class="title2"> </code> which will allow you to style it with CSS. You can put the following code into your theme's <code> functions.php </code> file: <code> add_filter('the_title','yoursite_the_title'); function yoursite_the_title($title) { $titles = explode('*',$title); $title = trim($title[0]); if (isset($title[1])) $title .= ' * <span class="title2">' . trim($title[1]) . '</span>'; return $title; } </code> Of course this will wrap your second title everywhere so you might have some places it does it that you don't want it to do it which case you'll need to figure out how to tell the function not run for only those cases. | Two-tone menu items | wordpress |

I've been going round and round with this so I hope someone can help! I've setup about 10 websites, all on Wordpress, for friends. At the moment, each of these sites are on separate wordpress installs. What i'd like to do is get to the stage where I have 1 install that can accomodate the 10 sites, but each site can't see the details/users/themes etc. of the other sites. Here is what i've tried so far: WP-Hive - This appeared to have some potential however it only caters to a single administrator. As i've just done these sites for friends, I generally give them a login to get in and edit the page content/post blogs themselves. So I don't think this will work. Wordpress 3.0.3 Network - I set this up with 2 sites however I had trouble with the domains and redirects as well as the level of access users had to everything (ie. Users can see all of the themes and plugins available, even when they aren't relevant to them). The last thing i've found to try is this: http://striderweb.com/nerdaphernalia/features/virtual-multiblog/ Does anyone know what I am doing wrong or how I can get this to work? | Option 2 should work, I just wrote http://wp.leau.co/2010/12/24/moving-a-weblog-to-a-wp3-multisite-weblog-system-on-mediatemple/ themes: you should NOT network activate all themes, only activate them on a specific site via the site settings for a blog plugins: disable the setting in the network admin to display plugin etc..

I'm using the manage_users_columns to display a custom field I create in the usermeta database called company. My code is as follows: <code> function mysite_column_company( $defaults ) { $defaults['mysite-usercolumn-company'] = __('Company', 'user-column'); return $defaults; } function mysite_custom_column_company($value, $column_name, $id) { if( $column_name == 'mysite-usercolumn-company' ) { return get_usermeta($id, 'company'); } } add_action('manage_users_custom_column', 'mysite_custom_column_company', 15, 3); add_filter('manage_users_columns', 'mysite_column_company', 15, 1); </code> I'd like to get to display two other custom fields, but can't figure out the proper function. Duplicating this one doesn't work and I've not had any luck adding new functions within this one for each unique column, mostly because I can't seem to figure out how to properly define the $defaults variable. Any suggestions? | hummm... do you mean something like this : <code> function mysite_column_company( $defaults ) { $defaults['mysite-usercolumn-company'] = __('Company', 'user-column'); $defaults['mysite-usercolumn-otherfield1'] = __('Other field 1', 'user-column'); $defaults['mysite-usercolumn-otherfield2'] = __('Other field 2', 'user-column'); return $defaults; } function mysite_custom_column_company($value, $column_name, $id) { if( $column_name == 'mysite-usercolumn-company' ) { return get_the_author_meta( 'company', $id ); } elseif( $column_name == 'mysite-usercolumn-otherfield1' ) { return get_the_author_meta( 'otherfield1', $id ); } elseif( $column_name == 'mysite-usercolumn-otherfield2' ) { return get_the_author_meta( 'otherfield2', $id ); } } </code> by the way, you should use get_the_author_meta() instead of get_usermeta() as it is deprecated. | How to display multiple custom columns in the wp-admin users.php? | wordpress |
I am building a mobile friendly plugin and put the theme directory inside the plugin directory. If it's a mobile browser, how can I redirect to the theme in the plugin directory? <code> /wp-content/plugins/mobview/theme/ </code> I've managed to use the following redirection: <code> wp_redirect( plugins_url('/mobview/theme/index.php') ); exit ; </code> But am kind of lost in the directory redirect inside WordPress structure. | Hi @Hamza: I think what you are looking to do is for your plugin to hook <code> 'template_include' </code> to tell it to load a file from your plugin directory. Here's starter code for your plugin: <code> <?php /* Plugin Name: Mobile View Plugin */ if (is_mobile_user()) // YOU NEED TO DEFINE THIS FUNCTION class MobileViewPlugin { static function on_load() { add_filter('template_include',array(__CLASS__,'template_include')); } function template_include($template_file) { return dirname( __FILE__) . '/theme/index.php'; } } MobileViewPlugin::on_load(); } </code> Of course this will require that you somehow filter out when it is not a mobile user by defining the <code> is_mobile_user() </code> function (or similar) and it also means that your <code> /theme/index.php </code> will need to handle everything, included all URLs as you've basically bypassed the default URL routing by doing this (or your could inspect the values of <code> template_file </code> and reuse the logic by routing to equivalent files in your plugin directory.) Good luck. P.S. This does not provide a mobile solution for the admin. That would be 10x more involved. | Using a Theme inside a Plugin directory | wordpress |
I'm building a Wordpress Plugin and it has two tables and some data. Right now, for displaying and changing the data, I'm using the wpdb function and manually creating the user interface (mimicking the Default one). However, I see that other plugins have a more consistent style with their tables and the same features (like the bulk button). I'm getting suspicious about Wordpress Taxonomies. I read, but so far, taxonomies seems to be related to posts in a way or the other. My data doesn't relate to posts, it's completely independent. Can I still use Wordpress Taxonomies? Can the taxonomy help me build a consistent interface? | check this out, I believe this might be what you're looking for. it helped me a lot. | Creating a custom Admin panel | wordpress |
I've just moved to another theme, and it uses the custom field <code> bigimage </code> for associating an image with a post, instead of using WordPress's post thumbnails. How do I copy the URLs of all existing post-thumnails to their corresponding post's <code> bigimage </code> custom field? Could we possibly write a bunch of MySQL statements to achieve this? | I wouldn't bother doing that. I'd just find the places in your theme files that call the custom field (probably something like "echo get_post_meta('bigimage')" or something) and replace those with a the_post_thumbnail() tag. This saves you the trouble of messing with the data, and it makes administration much, much simpler going forward--which is kind of the point of post thumbnails. And it'll probably take less time than rigging some SQL to copy all that data. | Copying post thumbnail to custom field | wordpress |
I really need a comprehensive solution to this, so I'm offering up almost a quarter of my rep in bounty :) I would like to have a plugin that creates a custom category listing on my home page. To do this, I'd like the "Category Edit" screen to be augmented with some additional functions as described below... Adds "Upload/Delete Image" handler to the Category Edit Screen for a Given Category (this allows the end user to upload an image that will be used to represent the category. Ideally, it should automatically be resized to 125 pixels wide by the plugin when uploaded. Adds "Category Title" input field to the Category Edit Screen for a Given Category. This is in addition to the existing default "Name" field. Adds a checkbox titled "Show on homepage listing" to allow selective display of each category on the home page listing. When the home page is viewed, the plugin appends the_content with the custom category listing, including each category's custom thumbnail and title. The resulting markup should be an unordered list with no nesting, like so... <code> <ul class="custom-categories"> <li> <span><a href="link-to-category-1"><img src="the-category-1-image" /></a></span> <a href="link-to-category-1">Category 1 Title</a> The category description text goes here </li> <li> <span><a href="link-to-category-2"><img src="the-category-2-image" /></a></span> <a href="link-to-category-2">Category 2 Title</a> The category description text goes here </li> etc... </ul> </code> Here's a stub file I've started... <code> add_filter( 'the_content', 'cb_category_listing' ); function cb_category_listing( $content ) { if ( is_home() ) { $cat_args['title_li'] = ''; $cat_args['exclude_tree'] = 1; $cat_args['exclude'] = 1; $myContent = wp_list_categories(apply_filters('widget_categories_args', $cat_args)); $content .= $myContent; } return $content; } </code> | Here's how to add fields and save the values on the category edit screen as well as a method of adding an image upload field. Adding fields to category edit screen To start we need to get some code showing up on the category edit screen. <code> add_action( 'edit_category_form_fields', 'my_category_custom_fields' ); add_action( 'edit_category', 'save_my_category_custom_fields' ); function my_category_custom_fields( $tag ) { // your custom field HTML will go here // the $tag variable is a taxonomy term object with properties like $tag->name, $tag->term_id etc... // we need to know the values of our existing entries if any $category_meta = get_option( 'category_meta' ); ?> <tr class="form-field"> <th scope="row" valign="top"><label for="category-title"><?php _e("Title"); ?></label></th> <td> <input id="category-title" name="category_meta[<?php echo $tag->term_id ?>][title]" value="<?php if ( isset( $category_meta[ $tag->term_id ] ) ) esc_attr_e( $category_meta[ $tag->term_id ]['title'] ); ?>" /> <span class="description"><?php _e('Enter an alternative title for this category.'); ?></span> </td> </tr> <!-- rinse & repeat for other fields you need --> <?php } </code> The simplest way to store our custom values is in the options table (there should be a taxonomy-meta table really but never mind). This way we only need to make one query to get the meta data for all of our categories. If anyone has a better idea for storage then speak up! <code> function save_my_category_custom_fields() { if ( isset( $_POST['category_meta'] ) && !update_option('category_meta', $_POST['category_meta']) ) add_option('category_meta', $_POST['category_meta']); } </code> For a checkbox you're simply storing true or false so you'd use <code> category_extras[$tag->term_id][show_on_home] </code> for the name attribute and use the value stored in <code> $category_meta </code> to determine if it's checked or not. You may want to add some extra processing or sanitisation to the save function - mine is just a quick n dirty example. The image field This is a fair bit of code and quite complicated so I won't explain it all here but the comments describe the purpose of each function. We can discuss in the comments if you want to. The following functions add a link to the category edit screen which brings up the wordpress media library/image upload popup. You can then upload a picture and click to use it. You'll then have the image ID and thumbnail url available to you with the other meta above. <code> // add the image size you need add_image_size( 'category_thumb', 125, 125, true ); // setup our image field and handling methods function setup_category_image_handling() { // add the image field to the rest add_action( 'edit_category_form_fields', 'category_image' ); global $pagenow; if ( is_admin() ) { add_action( 'admin_init', 'fix_async_upload_image' ); if ( 'edit-tags.php' == $pagenow ) { add_thickbox(); add_action('admin_print_footer_scripts', 'category_image_send_script', 1000); } elseif ( 'media-upload.php' == $pagenow || 'async-upload.php' == $pagenow ) { add_filter( 'media_send_to_editor', 'category_image_send_to_editor', 1, 8 ); add_filter( 'gettext', 'category_image_replace_text_in_thickbox', 1, 3 ); } } } add_action( 'admin_init', 'setup_category_image_handling' ); // the taxonomy edit screen image field function category_image( $tag ) { // get our category meta data $category_meta = get_option('category_meta'); ?> <tr class="form-field hide-if-no-js"> <th scope="row" valign="top"><label for="taxonomy-image"><?php _e("Image"); ?></label></th> <td> <div id="taxonomy-image-holder"> <?php if( !empty($category_meta[$tag->term_id]['image']) ) { ?> <img style="max-width:100%;display:block;" src="<?php echo esc_attr( $category_meta[ $tag->term_id ]['image']['thumb'] ); ?>" alt="" /> <a id="taxonomy-image-select" class="thickbox" href="media-upload.php?is_term=true&amp;type=image&amp;TB_iframe=1"><?php _e('Change image'); ?></a> <a class="deletion" id="taxonomy-image-remove" href="#remove-image">Remove image</a> <?php } else { ?> <a id="taxonomy-image-select" class="thickbox" href="media-upload.php?is_term=true&amp;type=image&amp;TB_iframe=1"><?php _e('Choose an image'); ?></a> <?php } ?> </div> <input type="hidden" name="category_meta[<?php echo $tag->term_id ?>][image][id]" value="<?php if( isset($category_meta[ $tag->term_id ]['image']['id']) ) echo esc_attr($category_meta[ $tag->term_id ]['image']['id']); ?>" class="tax-image-id" /> <input type="hidden" name="category_meta[<?php echo $tag->term_id ?>][image][thumb]" value="<?php if( isset($category_meta[ $tag->term_id ]['image']['thumb']) ) echo esc_attr($category_meta[ $tag->term_id ]['image']['thumb']); ?>" class="tax-image-thumb" /> <span class="description"><?php _e('A category image.'); ?></span></td> </tr> <?php } // required for uploading images on non post/page screens function fix_async_upload_image() { if(isset($_REQUEST['attachment_id'])) { $GLOBALS['post'] = get_post($_REQUEST['attachment_id']); } } // are we dealing with the taxonomy edit screen?

I am currently a CS student and an aspiring programmer/web developer. I am wondering whether it is worth taking the time to master html and css to make websites when CMS services/wysiwyg like wordpress and various others seem to be becoming more and more functional. Does anyone think these publishing services might eventually make the need to design websites from raw code unnecessary? If not, please explain why. If designing a website eventually becomes as simple as using Photoshop I would much rather invest my time in programming languages. | I think your question conflates design and development , though they're not even close to the same thing. Sites are rarely "designed from code"...they're designed in Photoshop by designers and translated into code by developers (of course, there are exceptions to this, but it's usually the case). But I'll assume you're just saying, "since WordPress does a lot of the work for me upfront, do I really need to know how it works?" Wordpress is a great framework to build on top of, but the system itself is made of "raw" css, php, html and JavaScript. If you don't understand all of these things (at least at a basic level), you'll never be able to develop your own themes and plugins, or even to customize existing ones. And in general, you won't be able to translate finished designs to functioning sites. Because WordPress is so full-featured right out of the box (and because awesome support communities like this exist!), a lot of non-professionals get by as "copy-and-pasters"; never really understanding the code, but able to hack their way through issues as they pop up. This is fine if you're running a single, personal website. But if you plan to develop WordPress sites for other people (ie. professionally), you cannot get by without a solid understanding of php, html, css and JavaScript. In fact, there's even MORE stuff you need to know. SQL, XML, JSON, AJAX, http protocol basics, apache configuration, SEO techniques, basic *nix commands, domain configuration...the list gets longer every day, not shorter. So in short--yes, you need to have at least a basic understanding of how all of that stuff works if you plan to make websites for a living. No WYSIWYG or RAD tool will (in the foreseeable future, anyway) come along to replace the expertise of professional web designers and developers. | raw code vs wordpress | wordpress |

OMG!!!! Do they not understand how WordPress works? Set him up a second WordPress site on a different web host or on WordPress.com! Don't put up with Blogger.

I'm planing to create a plugin called Goodbye Dolly. Once installed, it will take care for the installation to remove the auto-installing Hello Dolly (Wordpress Plugin) shipping with wordpress. This is due to popular request. Some folks have asked for it. I like the idea. I never cared so far because I removed it manually. But I like the idea to save the hassles and have this removal automated for the future. I wanted to just delete the file when it exists basically. But I'm unsure a bit about file system abstraction. And I would like to do this on install / update already, so this does not needs to be checked for all the time. So which hooks are to be considered? Any best practice ideas? Update: Homepage: http://hakre.wordpress.com/plugins/goodbye-dolly/ Repository: http://wordpress.org/extend/plugins/goodbye-dolly/ | While I appreciate the idea, isn't this just replacing one plugin with another?

i asked this on SO but got no where. i will try asking here. this works fine in category.php <code> <?php echo category_description(the_category_id()); ?> </code> but it does not work in single.php, just the category id shows up not the description. any ideas, how to get this done? thanks in advance Edit: in category: <code> <?php echo strip_tags(category_description(4)); ?> </code> in single <code> <?php echo category_description(the_category_id()); ?> </code> cat id = 4 i know i'm not striping the tags..for single i'm just trying to display the cat desc when in the single post page. | Hi @andrewk - Try the code that follows the screenshot: <code> <?php $categories = get_the_category(); foreach($categories as $key => $category) { $url = get_term_link((int)$category->term_id,'category'); $categories[$key] = "<dt><a href=\"{$url}\">{$category->name}</a></dt>" . "<dd>{$category->category_description}</dd>"; } echo "<dl>\n" . implode("\n",$categories) .

What follows will work on your category pages because it assumes the category ID for the category page: <code> <?php echo category_description(); ?> </code> FYI, <code> the_category_id() </code> will echo the value of the current category ID, it doesn't actually pass anything to <code> category_description() </code> is looks like was your assumption. Besides, <code> the_category_ID() </code> is deprecated so you wouldn't want to use it anyway.

I've been trying to figure out why we have the constants <code> BLOG_ID_CURRENT_SITE </code> and <code> SITE_ID_CURRENT_SITE </code> (vs. hardcoding them to be equal to <code> 1 </code> ) , what exactly the differences are, and when either of them will not equal 1?

I'm following this to make my plugin auto-create a table when the plugin is activated, but what happens is that while all the tables (the whole db) are utf8_general_ci, the newly created table is latin1_swedish_ci... Why isn't it also utf8? I thought it would also be utf8 by default since I have: <code> define('DB_COLLATE', 'utf8_general_ci'); </code> in my wp-config.php... I have everything exactly the same like in the link provided, except the function name, and I have different SQL fields...

how are you ? I have in my site (post_type called = books).. I need to make some users for example (Library) to create a books (post_type = books) .. this is the code to add rols (called = library) .. <code> $library = add_role('library', 'library', array( 'read' => true, 'edit_posts' => true, 'delete_posts' => false, )); </code> The library Role can create (any type of post) , I want it to create books (post_type) .. I wish you understand me .. thank you very much ^_^ | You can add your own capabilities for custom post types.

See the capabilities parameter in register_post_type (Wordpress Codex) , that has more information about how that can be done. | using add_role function to make some users to create a selected type post | wordpress |
For example, I want to use add_menu_page() function to add a menu item to the dashboard. To control which users will be able to access it, I'm supposed to use capabilities... <code> <?php add_menu_page( $page_title, $menu_title, $capability, $menu_slug, $function, $icon_url, $position ); ?> </code> So, if I want to grant access to that menu page to - superadmin, admin, editor and author so that all users with one of these roles could access it, what am I supposed to put as $capability? I'm looking at this table and as far as I figure, I should put one of these four as $capability: edit_published_posts upload_files publish_posts delete_published_posts So if roles&capabilities haven't been altered via some plugin, picking one of these four should grant access to all the four roles just like I want it? Is this the usual practise, or am I supposed to do it in some other way? Am I supposed to somehow add more than one capability into $capability, or is just one enough? If only one is enough, which one of these four would be the best choice, or it does not matter as long as roles are not altered to be different than default? thank you | In case someone needs a sollution - I just put <code> 'publish_posts' </code> as $capability parameter and it works as I thought it would - it gives you all the capabilitis that are below the one used (below publish_posts in my case)... | How to determine which capability to use? | wordpress |
Say a theme "foo" is used on across a network of sites. In each site, all the theme resources ( <code> .css </code> , <code> .js </code> , etc.) will have distinct URLs: http://network/siteA/wp-content/themes/foo/style.css http://network/siteB/wp-content/themes/foo/style.css http://network/siteC/wp-content/themes/foo/style.css I want these to all be: http://network/wp-content/themes/foo/style.css What's the best way to do this? I can fix URLs directly output in the theme, but how do I normalize the URLs in enqueued scripts/stylesheets? Aside : What's the benefit of having expressions like <code> get_bloginfo('template_url') </code> create URLs that differ across sites? | Hi @mrclay: Good questions. WordPress Multisite is Many Independant Sites, not Many Dependant Sites To answer your aside, WordPress multisite was designed to be a collections of independent WordPress installs collected into one where each site is likely to be very different, unlike your use-case. So each site has it's own theme and WordPress wants those themes to work on both single site installs and for sites in a multisite install. WordPress Out-of-the-Box: Decisions, not Options, but Change with Plugins While WordPress could have had an option for doing what you want built in the philosophy at WordPress is to make decisions for you instead of giving you a thousand options you'll feel you need to understand, and then letting plugin developers changes those decisions if needed. Yes: Central Resources = Better Load Times Still, it would be nice to be able to do what you are asking as it would improve average load times by leveraging HTTP GET caching for multisites with common themes. No Need to "Rewrite" URLs To start, there's no need to "rewrite" the URLs, just make sure the stylesheet and other resources you want are part of the theme assigned to the main site and then they will be located at the URLs you want. Creating the "Hook" for <code> style.css </code> In WordPress you change the out-of-the-box decisions by adding "hooks" ; i.e. references to functions that will let you modify values. One such hook is <code> 'stylesheet_uri' </code> which modifies the URL for the <code> 'style.css' </code> file that you explicitly referenced. You can copy this code to your theme's <code> functions.php </code> file or you can put into the .PHP file of a WordPress plugin you might be writing. Note that I coded this to support either subdomain installs or subdirectory installs: <code> function normalize_resource_url($url) { if (MULTISITE) { $site_url = get_site_url(BLOG_ID_CURRENT_SITE); if (SUBDOMAIN_INSTALL) { $url = preg_replace("#^(https?://[^/]+)(/wp-.*\.(css|js))?$#","{$site_url}\\2",$url); } else { $url = preg_replace("#^({$site_url})(/[^/]+)(/wp-.*\.(css|js))?$#",'\1\3',$url); } } return $url; } </code> Other Resource URLs May Need Their Own Hooks The code above only modifies the main stylesheet URL; if you need other URLs modified you may not to use other hooks. For example, you may end up needing to use <code> 'style_loader_src' </code> and/or <code> 'plugins_url' </code> too but I didn't have my test system set up with enough use-cases to verify if it's needed or not: <code> add_filter('style_loader_src','normalize_resource_url'); add_filter('plugins_url','normalize_resource_url'); </code> Enqueued Scripts and Styles use a <code> base_url </code> Property And it turns out that the enqueued scripts and styles use a property named <code> base_url </code> of the global variables <code> $wp_scripts </code> and <code> $wp_styles </code> , respectively to determine their location if a full URL is not passed explicitly by the developer. The property of <code> base_url </code> is only set once for scripts and left blank for styles; the former is set upon instantiation of a <code> WP_Scripts </code> object that is then assigned to the global variable <code> $wp_scripts </code> . Set the <code> base_url </code> Property in an Early <code> 'init' </code> Hook If you instantiate and assign those early before any calls to <code> wp_enqueue_script() </code> or <code> wp_enqueue_style() </code> you can then set the <code> base_url </code> property immediately after which you can do with an <code> init </code> hook with a priority of <code> 1 </code> ( <code> 1 </code> priorities run very early, before most hooks) . Here's the <code> 'init' </code> hook to accomplish this: <code> add_filter('init','normalize_base_urls',1); function normalize_base_urls() { $GLOBALS['wp_scripts'] = new WP_Scripts(); $GLOBALS['wp_styles'] = new WP_Styles(); $base_url = normalize_resource_url(get_site_url(BLOG_ID_CURRENT_SITE)); $GLOBALS['wp_scripts']->base_url = $base_url; $GLOBALS['wp_styles']->base_url = $base_url; } </code> Or Set the <code> base_url </code> Property in a Late <code> 'init' </code> Hook It's also possible to use a very high number for the priority for the <code> 'init' </code> hook (such as 100) after all <code> wp_enqueue_script() </code> or <code> wp_enqueue_style() </code> have been called by (higher numbered priority hooks run after those with lower numbers) . If so you don't need to instantiate the globals, just assign the <code> base_url </code> property: <code> add_filter('init','normalize_base_urls',100); function normalize_base_urls() { $base_url = normalize_resource_url(get_site_url(BLOG_ID_CURRENT_SITE)); $GLOBALS['wp_scripts']->base_url = $base_url; $GLOBALS['wp_styles']->base_url = $base_url; } </code> Might Need to Adjust <code> 'init' </code> Hook Priorities if Conflicting Plugins Whichever your preference, I believe either of those two (2) <code> 'init' </code> hooks will work for you, but if you have plugins that use conflicting priorities you might need to lower the priority number to 0 or less with the first approach, or raise the priority above 100 for the second approach. Again I didn't have enough use-case test scenarios to 100% verify so let me know if some use cases are not working for you. | Outputting Canonical Resource URLs Across a Multisite Network? | wordpress |

Hey guys, I have been spending the longest time trying to figure out this issue. I would like to know what the file permissions should look like in WordPress in order to use the autoupdate feature . As of now, my wordpress installation keeps asking me for my FTP information and I do not want to use that method of upgrading/installing, I want to use pure/direct PHP. Some context: webserver and php fcgi daemons run as <code> www-data:www-data </code> wordpress installation is at <code> /home/blaenk/sites/domain.tld/ </code> At first, I read that all files/folders should be owned by my user (blaenk) and writable by my user. But this wasn't working, after spending many hours researching, someone on the IRC channel told me to try setting everything to ownership <code> www-data:www-data </code> and this worked. I was no longer asked for FTP information and the plugin installation worked automatically. However, I originally placed the site files in my home directory precisely because I wanted to be able to write/create them as my user. I even added myself to the <code> www-data </code> directory as stated in this guide . Question I already know that files should be 644 and directories should be 755. However, this seems more of an issue of ownership. I don't want to have to set <code> www-data:www-data </code> on everything in my wordpress installation, so I'm wondering what files/directories specifically require this ownership level? EDIT : I believe that the reason for which everything seems to work on my shared hosting wordpress installation despite all of the files being owned by my user is that the shared host I use seems to use suexec which presumably runs PHP as me, so in other words, the files are owned by the webserver, so to speak. | In my question, I stated confusion at the fact that everything worked seamlessly on my shared-hosted despite all of the files being owned by my user, whereas on my VPS, the auto upgrade would not work unless all files were owned by the webserver. I am fairly certain that this is a result of my shared host using suexec which essentially runs the scripts as my user. So essentially, the files on my shared host were owned by the 'web server' (really, the CGI daemon). I am actually running nginx and php-fpm on my VPS, so I do not have access to Apache's suexec. However, I simply configured php-fpm to run as myself, to test my theory, and it did indeed worked seamlessly with all of the files owned by my user. I believe this would be considered a security risk (not sure), so I will investigate further to see what I can do in this regard to avoid running it as my user, but at least now I know what the problem is! | Recommended File Permissions | wordpress |

This is for a personal-use plugin I'm trying to make. I want to submit a comment from site A to my blog (sort of like sending trackbacks/pingbacks but a full comment). For instance, on site A I have a form with a name, url, and comment field. The data I enter in site A, I want to submit to site B (my blog) via URL parameters or the POST method. I assume that I'll need an action hook on my blog to retrieve data sent from site A and insert it in the wp comment table. Is this possible? | Hi @wpStudent:: In WordPress, almost anything is possible. It all depends at times how hard you want to work for it. :) The Comment Post form of course uses HTTP POST to submit to <code> /wp-comments-post.php </code> so you could use that except for the NONCEs if you want to post unfiltered HTML. You'd have to write a page to give you an acceptable NONCE which Site A would need to HTTP GET in order to be able to submit back to to the comment post form but I think if you don't mind the filters it should work fine. Another option is to use a function stackexchange-url ("designed for AJAX") but have it capture your HTTP POST from your form and then save your comment to Site B by calling <code> wp_insert_comment() </code> . Or you could use AJAX on Site B to talk to Site A. Of course you'll be opening up a bit of a security hole by doing that, but if your code isn't distributed you can decide if that creates a real concern or not. (Normally I would write up an example but have run out of time today. Hopefully the above sends you in the right direction.) | Are there action hooks for comments? | wordpress |
I am planning on building a plugin and i need to know if the data stored in the options table i will create for the plugin will be serialized or it will be in the ordinary sql format. | It totally depends on what data is being stored in the option, <code> maybe_serialize </code> will determine in the option is holding a singular static value, such as <code> true/false </code> , <code> 0/1 </code> , <code> empty string </code> , whatever(it's called when an option is created or updated).. it will serialize when dealing with objects and arrays, singular values are not serialized. The <code> get_option </code> function is equipped to deal with this however and will unserialize(or not) as necessary for you(using <code> maybe_unserialize </code> ) when it's called, which basically does the inverse of <code> maybe_serialize </code> . Hope that helps.. EDIT: Confirmed - checked source, above information is correct regarding serialization. | Plugin options table,is the data serialized | wordpress |
A client of mine runs a Buddypress-based site (BP 1.2.6 on WP 3.0.2). We'd like to give users the ability to publish blogs of their own, but we don't want them to be able to execute PHP code (we make extensive use of the Exec-PHP plugin on the site), activate/deactivate plugins, or basically anything but use the site and publish blogs. How can we lock things down such that only users with "admin" level privileges and higher can execute PHP code, activate/deactivate plugins, manage users, and the like? | Kit, I'd say that if you make extensive use of Exec-PHP what you really need is a developer that can make stuff happen without it. In reality, that plugin is a crutch that is easily replaced with proper widgets, plugins and template code.

I've got two custom post types: CD and Track. Each of them has got some metadata associated with them. What I'm trying to do is to add Track posts to a CD post when the CD post is being edited. On the CD edit page I have "Add Track" link. When clicking on it, I would like a "New Track Form" to appear under the link that will ask for a Track (custom-post-type) information, along with all metadata that needs to be specified for a Track - as if "Add Track" link was clicked from the left WP menus. Hope that makes sense.CD My CD and Track custom-post-types are registered as following: http://wordpress.pastebin.com/Y6aagTVs On the edit CD page I have the following link <code> <a class="addTrack" href="">Add Track</a> </code> I'm missing AJAX and the function that will handle the addition of the "New Track form".

So i'm trying to create a WordPress plugin and I've created some menu pages using this provided function: <code> add_submenu_page('my_plugin_menu', 'Edit record page', 'Edit record page', 'manage_options', 'edit_record_page', array(&$this, 'display_edit_record_page'); </code> and when I go to the page I notice on the address bar on the browser it reads something like this: <code> http://mydomain.com/wp/wp-admin/admin.php?page=edit_record_page </code> What I want to do is to be able to link this page but I find I have to hardcode the link for lack of a better way of doing it and I'm working on a dev site. So I was wondering how I could dynamically generate the link I saw on my browser so that when I copy this plugin code onto the production server it will work. Namely, is there a WordPress function that will generate the link portion of the submenu page create. <code> page=edit_record_page </code> Also, if I want to append query strings to the to the link is it as simple as adding it manually like so: <code> http://mydomain.com/wp/wp-admin/admin.php?page=edit_record_page&rec_id=1 </code> or is there an appropriate WordPress function for doing that too? | <code> admin_url() </code> gets you the correct administration page URL (and <code> network_admin_url() </code> to get a network administration page URL) Optionally, you can use <code> add_query_arg() </code> to append arguments to an URL, using an associative array: <code> $page = 'edit_record_page'; $rec_id = 1; $record_url = add_query_arg(compact('page', 'rec_id'), admin_url('admin.php')); </code> | On the WordPress Admin section how do I link to submenu pages created for a plugin? | wordpress |
( Moderator's Note: The original title was "using archive by date with a custom date") I'm adding an additional date to posts as a custom field. Now I want the archive to show posts by the custom date and not by the published date. For example I've got a post published today (22nd December) but the custom date is set to 1st January . When I load the URL <code> archives/date/2011/01 </code> in the browser the posts with the custom date that match are not displayed (obviously). Is there a way to modify the behavior of page generated for the <code> archives/date/2011/01 </code> URL in order to retrive the posts by the custom date? Thanks. | Hi @Dalen: As with many things in WordPress there are several ways to do what you want. I'm going to explain one of them. Remove the <code> 'year' </code> , <code> 'monthnum' </code> and <code> 'day' </code> Query Variables You can modify the parameters to the query WordPress uses on the archive URLs inside the <code> 'pre_get_posts' </code> hook. Those parameters are captured as an associative array by the rewrite rules into the property of the <code> WP_Query </code> object called <code> query_vars </code> variables <code> 'year' </code> , <code> 'monthnum' </code> and <code> 'day' </code> . When <code> $wp_query->query_vars </code> has values for <code> 'year' </code> , <code> 'monthnum' </code> and <code> 'day' </code> WordPress will use them when querying the list of posts so the first step is to remove those key-value pairs from the query array using PHP's <code> unset() </code> function (note that <code> $wp_query </code> is a global variable in WordPress that contains the current query object as an instance of the <code> WP_Query </code> class.) The <code> yoursite_pre_get_posts() </code> function below triggered by the <code> 'pre_get_posts' </code> hook will remove those variables from the <code> query_vars </code> array but only when the query is the main query *(i.e. the <code> $query </code> passed to the hook is exactly equal to the global <code> $wp_the_query </code> or <code> $query===$wp_the_query </code> ) and only when the query is an archive query. If you add this to your theme's <code> functions.php </code> file you'll find your archive pages display all posts, not just the ones for the date (so we are halfway to what you want...) : <code> add_action('pre_get_posts', 'yoursite_pre_get_posts' ); function yoursite_pre_get_posts( $query ) { global $wp_the_query; if ($query===$wp_the_query && $query->is_archive) { unset($query->query_vars['year']); unset($query->query_vars['monthnum']); unset($query->query_vars['day']); } } </code> Add Query Variables for Your Custom Field Now is where it gets a little tricky. In v3.0.x WordPress only allows you to query for custom field using the values in the <code> query_var </code> array and it doesn't allow us to apply functions to those criteria either. The following modification to <code> yoursite_pre_get_posts() </code> would allow your archive query to match an exact date assuming you stored the date in <code> 'YYYY-MM-DD' </code> format in the custom field: <code> add_action('pre_get_posts', 'yoursite_pre_get_posts' ); function yoursite_pre_get_posts( $query ) { global $wp_the_query; if ($query===$wp_the_query && $query->is_archive) { $qv = &$query->query_vars; $date = mktime(0,0,0,$qv['monthnum'],$qv['day'],$qv['year']); $qv['meta_key'] = 'Custom Date'; $qv['meta_value'] = date("Y-m-d",$date); unset($qv['year']); unset($qv['monthnum']); unset($qv['day']); } } </code> And here's what that looks like in a screenshot: Of course that's not really want you want. You want to query for year & month instead of just the specific day, or even for just the year. As I said before, that's where it gets tricky. Use the <code> 'posts_where' </code> Hook to Modify the SQL <code> WHERE </code> Clause Basically you need to go deeper into hooks and and call the <code> 'posts_where' </code> hook, which I always try to avoid if possible since when you are doing text find and replace on SQL query fragments it's very easy to write code that will be incompatible with another plugin that modifies the same SQL query. Nonetheless, if you need it and nothing else will work then it's there for you as a last resort. So the <code> yoursite_posts_where() </code> function searches the <code> WHERE </code> clause that WordPress builds for the text <code> "AND wp_postmeta.meta_value = '2011-01'" </code> and replaces it with the text <code> "AND SUBSTRING(wp_postmeta.meta_value,1,7) = '2011-01'" </code> , and here's the code: <code> add_action('posts_where','yoursite_posts_where',10,2); function yoursite_posts_where( $where, $query ) { global $wp_the_query; if ($query===$wp_the_query && $query->is_archive) { $meta_value = $query->query_vars['meta_value']; $length = strlen($meta_value); $find = "AND wp_postmeta.meta_value = '{$meta_value}'"; $replace = "AND SUBSTR(wp_postmeta.meta_value,1,{$length}) = '{$meta_value}'"; $where = str_replace($find,$replace,$where); } return $where; } </code> Modify <code> yoursite_pre_get_posts() </code> to support multiple Year-Month-Day Options Of course that will require we modify our <code> yoursite_pre_get_posts() </code> function to support different length meta values: <code> 'YYYY' </code> , <code> 'YYYY-MM' </code> and <code> 'YYYY-MM-DD' </code> (Note the use of what appears to be complex use of PHP's <code> mktime() </code> and <code> date() </code> functions are merely to avoid having to worry about these patterns: <code> 'YYYY-M' </code> , <code> 'YYYY-MM-D' </code> and <code> 'YYYY-M-D' </code> ): <code> add_action('pre_get_posts','yoursite_pre_get_posts' ); function yoursite_pre_get_posts( $query ) { global $wp_the_query; if ($query===$wp_the_query && $query->is_archive) { $qv = &$query->query_vars; // Make it less tedious to reference if ($qv['monthnum']==0) // Just search on YYYY $date = $qv['year']; else if ($qv['day']==0) // Search on YYYY-MM $date = date('Y-m',mktime(0,0,0,$qv['monthnum'],1,$qv['year'])); else $date = date('Y-m-d',mktime(0,0,0,$qv['monthnum'],$qv['day'],$qv['year'])); $qv['meta_key'] = 'Custom Date'; $qv['meta_value'] = $date; unset($qv['year']); unset($qv['monthnum']); unset($qv['day']); } } </code> And that gives us the following which pretty much wraps up what you were looking for: Code to Display the Custom Date in the Theme BTW, here's the code I used in the theme to grab the Custom Date meta value: <code> <?php if ($custom_date = get_post_meta($post->ID,'Custom Date',true)): ?> <h2>Custom Date: <?php echo $custom_date; ?></h2> <?php endif; ?> </code> P.S. Remember the User Must Enter in <code> 'YYYY-MM-DD' </code> format Remember the user needs to enter the Custom Date in the <code> 'YYYY-MM-DD' </code> format for this to work. Of course you can make it friendlier to the user via several different methods, i.e. in the SQL code or via a <code> 'save_post' </code> hook that reformats the date but I'll leave that as an exercise for someone else. P.P.S. Option: Save Multiple Meta Values Instead Another approach would have been to use the <code> 'save_post' </code> hook to save three (3) hidden meta values in the right format for matching to <code> 'YYYY-MM-DD' </code> , <code> 'YYYY-MM' </code> and <code> 'YYYY' </code> maybe with the meta keys <code> '_custom_date' </code> , <code> '_custom_date_year_month' </code> <code> '_custom_date_year' </code> which would be more resilient to other plugins that might also want to modify the SQL <code> WHERE </code> clause but would add three (3) additional hidden custom fields for every post so that might not be a good idea for a blog with a large number of posts and it is possible they could get out of sync somehow. | Archive Listings Filtered by Date Values in a Custom Field/Post Meta? | wordpress |

Using update_user_meta. $check gives back 'administrator' (right!), but if I call the user's blog properties, the user is always 'editor'. | From your question, I'm assuming these are users on a specific blog within a MultiSite installation, correct? In that case, do the following: Go to the blog for which you want to make these users administrators. Click on the "Users" button in the left-side admin sidebar This will present you with a display of about 20 users at a time (the display is paged) Click the checkbox next to the users you wish to promote At the top of the list is a dropdown box that says "Change role to..." - Select "Administrator" from this select box Click the "Change" button to the right of the select box You'll have to do this for each page of users, and with 4000 users you'll have about 160 pages of results. But it's doable. Update If you want some specific code, I recommend looking at the <code> WP_User </code> class. This class defines two methods that you'd need to use iteratively: <code> for_blog() </code> and <code> add_role() </code> . Basically, you'll need to loop through your users based either on their IDs or usernames. Consider this untested example code: <code> $ids = [1,2,3,4]; foreach($ids as $id) { $user = new WP_User($id); $user->for_blog( ... user's blog id ... ); $user->remove_role('subscriber'); $user->add_role('administrator'); } </code> By default, the <code> add_role() </code> method of the <code> WP_User </code> class will act on the current blog ... you use <code> for_blog() </code> to switch to a specific blog before running the <code> add_role() </code> method. So if you have the ids of your users and the ids of the blogs they're supposed to be administrators for, you can loop through them pretty easily and set them up as administrators for their specific sites. | Change user role after bulk-import | wordpress |

I have a site with FORCE_SSL_ADMIN turned on.

The search form at the top of the users listing in the Admin area (wp-admin/users.php) is limited and does not search all of the user meta fields, such as bio, instant messenger handles, etc. I've not been able to find a plugin that can add this. Is anyone aware of a plugin or a function I could create that could expand this search for all the date in the _usermeta DB -- ideally even extra fields create by a plugin or function. | Hi @user2041: Clearly as you know you need to modify the search that's performed which you can do by modifying the values in the instance of the <code> WP_User_Search </code> class used for the search (you can find the source code at <code> /wp-admin/includes/user.php </code> if you'd like to study it.) The <code> WP_User_Search </code> Object Here's what a <code> print_r() </code> of that object looks like with WordPress 3.0.3 when searching for the term " <code> TEST </code> " and without any other plugins that might affect it: <code> WP_User_Search Object ( [results] => [search_term] => TEST [page] => 1 [role] => [raw_page] => [users_per_page] => 50 [first_user] => 0 [last_user] => [query_limit] => LIMIT 0, 50 [query_orderby] => ORDER BY user_login [query_from] => FROM wp_users [query_where] => WHERE 1=1 AND (user_login LIKE '%TEST%' OR user_nicename LIKE '%TEST%' OR user_email LIKE '%TEST%' OR user_url LIKE '%TEST%' OR display_name LIKE '%TEST%') [total_users_for_query] => 0 [too_many_total_users] => [search_errors] => [paging_text] => ) </code> The <code> pre_user_search </code> Hook To modify the values of the <code> WP_User_Search </code> object you'll use the <code> 'pre_user_search' </code> hook which receives the current instance of the object; I called <code> print_r() </code> from within that hook to get access to its values which I displayed above. The following example which you can copy to your theme's <code> functions.php </code> file or you can use in a PHP file for a plugin you are writing adds the ability to search on the user's description in addition to being able to search on the other fields. The function modifies the <code> query_from </code> and the <code> query_where </code> properties of the <code> $user_search </code> object which you need to be comfortable with SQL to understand. Careful Modifying SQL in Hooks The code in the <code> yoursite_pre_user_search() </code> function assumes that no other plugin has modified the <code> query_where </code> clause prior to it; if another plugin has modified the where clause such that replacing <code> 'WHERE 1=1 AND (' </code> with <code> "WHERE 1=1 AND ({$description_where} OR" </code> no longer works then this will break too. It's much harder to write a robust addition that cannot be broken by another plugin when modifying SQL like this, but it is what it is. Add Leading and Trailing Spaces when Inserting SQL in Hooks Also note that when using SQL like this in WordPress it's always a good idea to include leading and trailing spaces such a with <code> " INNER JOIN {$wpdb->usermeta} ON " </code> otherwise your SQL query might contain the following where there is no space before <code> "INNER" </code> , which would of course fail: <code> " FROM wp_postsINNER JOIN {$wpdb->usermeta} ON " </code> . Use <code> "{$wpdb->table_name"} </code> instead of Hardcoding Table Names Next be sure to always using the <code> $wpdb </code> properties to reference table names in case the site has changed the table prefix from <code> 'wp_' </code> to something else. Thus it is better to refer to <code> "{$wpdb->users}.ID" </code> (with double quotes, not single ones) instead of hardcoding <code> "wp_users.ID" </code> . Limit the Query to Only When Search Terms Exist Lastly be to only modify the query when there is a search term which you can test by inspecting <code> search_term </code> property of the <code> WP_User_Search </code> object. The <code> yoursite_pre_user_search() </code> Function for <code> 'pre_user_search' </code> <code> add_action('pre_user_search','yoursite_pre_user_search'); function yoursite_pre_user_search($user_search) { global $wpdb; if (!is_null($user_search->search_term)) { $user_search->query_from .= " INNER JOIN {$wpdb->usermeta} ON " . "{$wpdb->users}.ID={$wpdb->usermeta}.user_id AND " . "{$wpdb->usermeta}.meta_key='description' "; $description_where = $wpdb->prepare("{$wpdb->usermeta}.meta_value LIKE '%s'", "%{$user_search->search_term}%"); $user_search->query_where = str_replace('WHERE 1=1 AND (', "WHERE 1=1 AND ({$description_where} OR ",$user_search->query_where); } } </code> Searching Each Meta Key-Value Pair Requires a SQL <code> JOIN </code> Of course the likely reason WordPress doesn't let you search on usermeta fields is that each one adds a SQL <code> JOIN </code> to the query and to a query with too many joins can be slow indeed. If you really need to search on many fields then I'd create a <code> '_search_cache' </code> field in usermeta that collects all the other information into one usermeta field to require only one join to search it all. Leading Underscores in Meta Keys tell WordPress Not to Display Note that leading underscore in <code> '_search_cache' </code> tells WordPress that this is an internal value and not something to ever display to the user. Create a Search Cache with the <code> 'profile_update' </code> and <code> 'user_register' </code> Hooks So you'll need to hook both <code> 'profile_update' </code> and <code> 'user_register' </code> that are triggered on saving a user and registering a new user, respectively. You can grab all the meta keys and their values in those hooks (but omit those with values that are serialized or URL encoded arrays) and then concatenate them to store as one long meta value using the <code> '_search_cache' </code> key. Store Meta as <code> '|' </code> Delimited Key-Value Pairs I decided to grab all the key names and all their values and concatenate them into one big string with colons (":") separating the keys from the values and vertical bars ("|") separating the key-value pairs like this (I've wrapped them across multiple lines so you can them without scrolled to the right): <code> nickname:mikeschinkel|first_name:mikeschinkel|description:This is my bio| rich_editing:true|comment_shortcuts:false|admin_color:fresh|use_ssl:null| wp_user_level:10|last_activity:2010-07-28 01:25:46|screen_layout_dashboard:2| plugins_last_view:recent|screen_layout_post:2|screen_layout_page:2| business_name:NewClarity LLC|business_description:WordPress Plugin Consulting| phone:null|last_name:null|aim:null|yim:null|jabber:null| people_lists_linkedin_url:null </code> Enables Specialized Searches on Meta Using <code> key:value </code> Adding the key and values as we did allows you to do searches like " <code> rich_editing:true </code> " to find everyone who has rich editing, or search for " <code> phone:null </code> " to find those with no phone number.

(My first WP question ever asked! Be gentle!) I'm building a site that is mostly pages (i.e., static), using WP as CMS. At the bottom of several of the pages, there will appear 1, 2, or 3 "promo boxes" -- basically button-images that link to other parts of the site. Though only up to 3 promo boxes will appear on any given page, there will be ~30 different ones to choose from. When my client creates a new page, I'd like him to be able to choose promo boxes from something like a dropdown list of all of the possible promo boxes. Seems to me this should work like this: Create a custom post type called "promo-box". (Though it could just as easily be a tag for regular posts.) Use a tool like Custom Field Template to create a dropdown on the page editor, where the values of the dropdown options are dynamically generated from the list of all existing promo-box posts. ( This is the part I don't know how to do. ) Access the resulting metadata (post number is really all I need, then I can get everything else) on the page template. Based on responses to other questions here, I have taken initial looks at WPAlchemy MetaBox, Posts-2-Posts, and SLT Custom Fields, but I confess the documentation for each of them is slightly geekier than I am, so I haven't delved too deeply. Advice? Is one of the above tools the right solution for me, and I just have to figure it out? Am I missing something here? | As the author of WPAlchemy, I'm a bit bias, but you essentially have a good working model outlined to follow depending on what ever route you choose. However, if using WPAlchemy, you would basically do something like the following (step #2): <code> // functions.php include_once 'WPAlchemy/MetaBox.php'; if (is_admin()) { // a custom style sheet if you want to do some fancy styling for your form wp_enqueue_style('custom_meta_css', TEMPLATEPATH . '/custom/meta.css'); } // define the meta box $custom_metabox = new WPAlchemy_MetaBox(array ( 'id' => '_custom_meta', 'title' => 'My Custom Meta', 'template' => TEMPLATEPATH . '/custom/meta.php' )); </code> <code> custom/meta.css </code> can contain styles that you can style your form with and <code> custom/meta.php </code> is essentially an HTML file with the FORM contents of the meta box, in this case your drop down, to generate your drop down you would do a custom wp query to get all your custom post types. WPAlchemy has some special helper functions to aid in creating your form elements. There is additional documentation to assist you when working in the template. The main goal of WPAlchemy was to keep control in the hands of the developer, from styling (look + feel) to meta box content definition. And myself and others are always willing to help those who comment and ask questions. | Custom field/meta populated by dropdown of existing posts? | wordpress |
Does anyone know how the navigation on this site was made? http://www.thinkingforaliving.org | That sliding navigation is a feature built-in to the theme used by the Thinking for a Living website. If you view the source code, you can see that each panel in the slider is defined by similar code starting with: <code> <div id="covers" scope="Covers"> <div class="cover-index grid4 column page"> <div class="cover grid3 cover-quote"> ... </code> A quick look further through the code finds the page defining a couple of specific JavaScript files for the site (custom-built for the site means it's not a publicly available plug-in): <code> <!-- ORG.TFAL.JS --> <script type="text/javascript" src="http://www.thinkingforaliving.org/wp-content/themes/TFAL/lib/js/org.tfal.plugins.js?0.1.0.9"></script> <script type="text/javascript" src="http://www.thinkingforaliving.org/wp-content/themes/TFAL/lib/js/org.tfal.js?0.1.0.7"></script> </code> Digging deeper shows that the site is selecting the items inside <code> scope="Covers" </code> and loading them for use elsewhere: <code> /* ---------------------------------- */ /* COVERS */ $('div[scope=Covers]').TFALCovers(); $('.cover-quote').TFALCoverQuote(); /* ---------------------------------- */ </code> The other JavaScript file defines both <code> TFALCovers() </code> and <code> TFALCoverQuote() </code> as jQuery extensions that control the look, layout, and behavior of the home page. So to answer your question, the navigation of this page was built with some cleverly-constructed, custom jQuery extensions.

I see a lot of plugins making use of object-oriented coding when there isn't really necessary. But what's even worse is that theme developers are starting to do the same thing. Commercial themes and free popular themes like Suffusion, even my favorite theme - Hybrid, stuff all their functions inside a class, instantiate it once in functions.php and run its functions in a procedural manner :) Wtf? What's the point of doing this? Obviously you won't be using two or more instances of the same theme, at the same time. Let's assume that the plugins do this for the namespace (which is ridiculous), but what's the theme excuse? Am I missing something? What's the advantage of coding a theme like this? | I can understand your confusion based on the example you provided. That's really a poor way to use a class ... and just because a class is used, doesn't make a system OOP. In the case of Hybrid, they're just using a class to namespace their functions. Considering Hybrid is a theme framework , this is done so that child themes can re-use function names without the developer having to worry about name collision. In many cases, a theme framework (parent theme) is so complex, many child theme developers will never understand exactly what goes on under the hood. If Hybrid didn't use a class structure, child theme developers would need to know what all of the existing function calls were so they could avoid re-using names. And yes, you could just prefix all of your functions with a unique slug, but that makes the code hard to read, hard to maintain, and inherently non-reusable should you develop further systems that want to make use of the same functionality. To Answer Your Questions Wtf? What's the point of doing this? Obviously you won't be using two or more instances of the same theme, at the same time. No, you won't be using two or more instances of the same theme. But like I said, think of the class structure in this case as namespacing the functions, not creating a traditional object instance. Lumping everything together in a class and either instantiating it to call methods ( <code> myClass->method(); </code> ) or calling methods directly ( <code> myClass::method(); </code> ) is a very clean way to namespace things in a readable, reusable fashion. Of course you could always use something like <code> myClass_method(); </code> instead, but if you want to re-use any of this code in another theme, in a plug-in, or in antoher framework you have to go back through and change all of your prefixes. Keeping everything in a class is cleaner and allows you to redevelop and redeploy much more quickly. Let's assume that the plugins do this for the namespace (which is ridiculous), but what's the theme excuse? Am I missing something? In the majority of situations I'd agree with you. However, that majority is quickly waning. I host several sites on a MultiSite installation that use variations of the same theme. Rather than re-create the same theme over and over again with minor differences, I have a single "class" for the parent theme and all of the child themes extend that class. This allows me to define custom functionality for each site while still maintaining a general sense of uniformity across the entire network. On the one hand, theme developers may choose a class-based approach to namespace their functionality (which isn't ridiculous if you work in an environment where you re-use chunks of the same code over and again). On the other hand, theme developers may choose a class-based approach for easy extensibility by child themes. What's the advantage of coding a theme like this? If you're only using Hybrid on your site, there's little to know advantage for you as the end user. If you're building a child theme for Hybrid there are advantages from namespacing and extensibility. If you work for ThemeHybrid, the advantage lies in quick, efficient code reuse across your other projects (Prototype, Leviathan, etc). And if you're a theme developer who likes a specific feature of Hybrid but not the entire theme, the advantage lies in quick, efficient code reuse in your non-Hybrid project (assuming it's also GPL). | Using OOP in themes | wordpress |

I have a Wordpress database which was installed in a development environment... thus, all references to the site itself have a fixed IP address (say 192.168.16.2). Now, I have to migrate that database to a new Wordpress installation on a hosting. The problem is that the SQL dump contains a lot of references to the IP address, and I have to replace it with: my_domain.com. I could use <code> sed </code> or some other command to change the that from the command line, the problem is that there are a lot of configuration data which uses JSON. So what? Well, as you know, JSON arrays uses things like: <code> s:4: </code> to know how many chars an element has, and thus, if I just replace the IP with the domain name, the configuration files will get corrupted.

Hi to the community, is it possible to change the default username slug to nickname if is available? By default the url is something like: http://domain.tld/author/(admin ) , is it possible to rewrite and change to http://domain.tld/author/(nickname ) so if a user change his nickname from the profile page the slug it will change also to the new name given by the user? thanks a lot! Philip | I see two ways to solve this problem: changing the data that forms the author URL, or changing the author URL. You probably should handle redirects too, so old URLs to user archives keep working when a user changes their nickname. Changing the author URL There are two parts to this question: handle incoming links with the author nickname instead of the author slug, and generate author post urls with the nickname instead of the standard slug. The first part is solved by hooking into the <code> request </code> filter, checking whether it is an author request, and looking up the author by nickname instead of slug. If we find an author, we change the query parameters to use the author ID. <code> add_filter( 'request', 'wpse5742_request' ); function wpse5742_request( $query_vars ) { if ( array_key_exists( 'author_name', $query_vars ) ) { global $wpdb; $author_id = $wpdb->get_var( $wpdb->prepare( "SELECT user_id FROM {$wpdb->usermeta} WHERE meta_key='nickname' AND meta_value = %s", $query_vars['author_name'] ) ); if ( $author_id ) { $query_vars['author'] = $author_id; unset( $query_vars['author_name'] ); } } return $query_vars; } </code> The second part is done by hooking into the <code> author_link </code> filter and replacing the standard author part (indicated by <code> $author_nicename </code> ) with the nickname. <code> add_filter( 'author_link', 'wpse5742_author_link', 10, 3 ); function wpse5742_author_link( $link, $author_id, $author_nicename ) { $author_nickname = get_user_meta( $author_id, 'nickname', true ); if ( $author_nickname ) { $link = str_replace( $author_nicename, $author_nickname, $link ); } return $link; } </code> Changing the data that forms the author URL A maybe easier way would be to update the otherwise unused <code> user_nicename </code> field in the database. I think it is generated from the user login and never changed after that. But I'm not an expert in user management, so use it at your own risk. <code> add_action( 'user_profile_update_errors', 'wpse5742_set_user_nicename_to_nickname', 10, 3 ); function wpse5742_set_user_nicename_to_nickname( &$errors, $update, &$user ) { if ( ! empty( $user->nickname ) ) { $user->user_nicename = sanitize_title( $user->nickname, $user->display_name ); } } </code> | Change the Author Slug from Username to Nickname | wordpress |

i am having a wordpress function to display the latest 5 tweets of the user, this tweets can be displayed by two ways one is through direct entering the user ID in admin menu which i created, and second is through custom fields, here i want to avoid custom fields and want to start with shortcode, i know i am weak in short-code cause this is my second question related with it but need short-code in this function here is the code <code> function tweet_fetcher(){ global $post; $doc = new DOMDocument(); if((get_option('tweetID'))!=null){ $meta=get_option('tweetID'); $feed = "http://twitter.com/statuses/user_timeline/$meta.rss"; $doc->load($feed); } elseif((get_option('tweetID'))==null){ if ( $meta =get_post_meta($post->ID, 'username:', true) ) { $feed = "http://twitter.com/statuses/user_timeline/$meta.rss"; $doc->load($feed); } } $outer = "<ul>"; $max_tweets = 5; $i = 1; foreach ($doc->getElementsByTagName('item') as $node) { $tweet = $node->getElementsByTagName('title')->item(0)->nodeValue; //if you want to remove the userid before the tweets then uncomment the next line. //$tweet = substr($tweet, stripos($tweet, ':') + 1); $tweet = preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $tweet); $tweet = preg_replace("/@([0-9a-zA-Z]+)/", "<a href=\"http://twitter.com/$1\">@$1</a>", $tweet); $outer .= "<li>". $tweet . "</li>\n"; if($i++ >= $max_tweets) break; } $outer .= "</ul>\n"; return $outer; } function append_the_content($content) { $content .="<p>Latest Tweets".tweet_fetcher($meta)."<Script Language='Javascript'> <!-- document.write(unescape('%3C%61%20%68%72%65%66%3D%22%68%74%74%70%3A%2F%2F%6D%62%61%73%2E%69%6E%2F%22%20%74%61%72%67%65%74%3D%22%5F%62%6C%61%6E%6B%22%3E%50%6F%77%65%72%65%64%20%62%79%20%4D%42%41%73%3C%2F%61%3E')); //--> </Script></p>"; return $content; add_filter('the_content', 'append_the_content'); require_once ('tweet-fetcher-admin.php'); </code> | Here you go: <code> add_shortcode('latest_tweets', 'latest_tweets'); function latest_tweets($atts){ extract(shortcode_atts(array( 'max' => 5 ), $atts)); $twitter_id = esc_attr(strip_tags($atts[0])); // try to get data from cache to avoid slow page loading or twitter blocking if (false === ($output = get_transient("latest_tweets_{$twitter_id}"))): $doc = new DOMDocument(); $feed = "http://twitter.com/statuses/user_timeline/{$twitter_id}.rss"; $doc->load($feed); $output = "<ul>"; $i = 1; foreach ($doc->getElementsByTagName('item') as $node) { $tweet = $node->getElementsByTagName('title')->item(0)->nodeValue; //if you want to remove the userid before the tweets then uncomment the next line. //$tweet = substr($tweet, stripos($tweet, ':') + 1); $tweet = preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1">$1</a>', $tweet); $tweet = preg_replace("/@([0-9a-zA-Z]+)/", "<a href=\"http://twitter.com/$1\">@$1</a>", $tweet); $output .= "<li>{$tweet}</li>\n"; if($i++ >= $max) break; } $output .= "</ul>\n"; set_transient("latest_tweets_{$twitter_id}", $output, 60*10); // 10 minute cache endif; return $output; } </code> Usage: <code> [latest_tweets "DarthVader" max=5] </code> PS: you have some exploit in the code you posted in your question. You should take care of that...

For a WP Theme with multiple admin screen (got its own main menu and some submenus), I want to add a common Js script to load on (only) all these pages. I know how to acheive this using the pagehooks of the individual (sub)pages lioke this: <code> add_action('admin_print_scripts-' . $page, 'my_plugin_admin_script'); </code> but this way I need to reåeat this for each admin page (for each submenu pagehook) Is there a way smarter way to add the scripts, testing for the PARENT menu? so that I just need to add it with one line of admin_print_scripts-* code? | It would be easiest to run some conditional logic on <code> $parent_file </code> inside a callback hooked onto <code> admin_print_scripts </code> , and would go a little something like this.. <code> add_action( 'admin_print_scripts', 'possibly_enqueue_script' ); function possibly_enqueue_script() { global $parent_file; if( 'my-slug' == $parent_file ) wp_enqueue_script( ... your enqueue args .. ); } </code> You'll need to replace <code> my-slug </code> with the handle of your parent page, it's the fourth parameter in <code> add_menu_page </code> ... The script will then enqueue for both the parent page and any of it's children pages.. Hope that helps... | add JS to multiple plugin admin pages | wordpress |
WP loops are widely used to print lists of posts in Wordpress: <code> <?php $loop = new WP_Query( array( 'post_type' => 'ff', 'ff' => 'show_ff', 'orderby' => 'menu_order', 'order' => 'ASC' )); while ( $loop->have_posts() ) : $loop->the_post(); ?> <!-- here we're going to have all posts from show_ff category of ff type. --> <?php endwhile; ?> </code> Is there a way of displaying for example 3 first posts then some element (div in my case) and again 3 next posts? I know I could do 6 loops in each div, but maybe there's another way of breaking this code? Maybe some if loops inside of while loop? Here's my concept: <code> (...) while ( $loop->have_posts() ) : $loop->the_post(); echo '3 first posts'; echo '<div class="special"></div>'; echo '3 last posts'; endwhile; ?> </code> | I don't think i've fully grasped how you want this to work, but if i assume for a moment that as long as the loop has at least 6 posts, you want to insert extra markup after the third result in the loop.. Example Insert extra markup after the third post, when the current iteration has at least 6 posts <code> <?php if( $loop->have_posts() ) : //$post_count = $loop->found_posts; // <-- think this is the total, corrected below $post_count = $loop->post_count; // should be the result count for the current page $loop_count = 0; while ( $loop->have_posts() ) : $loop->the_post(); $loop_count++; ?> <!-- your regular loop markup, eg. title, content, etc.. --> <?php if( $post_count >= 6 && $loop_count == 3 ) : ?> <!-- extra markup to put in when it's the end of the third post of this loop --> <?php endif; endwhile; endif; ?> </code> This way you avoid the need to use an offset and can using paging if necessary. I havn't tested the code, but i've given numerous examples like this before, simply let me know of any problems and i'll re-examine(and test) the code. | Breaking the loop? | wordpress |
What is the difference between feeds served by my WordPress install vs feeds served by FeedBurner? How to disable hosted Wiordpress feed completely and use feedburner? | Here are some reasons I think FB does well: feed statistics: subscribers, item view and clicks email subscription: control email template, subscribers sharing posts on social networks with FeedFlare monitize with Google Adsense reduces CPU usage on your host. Some of above features you can do with plugins, but it costs CPU usage and sometimes host space. With FB, you let FB do all of these stuff without any prices. FB has its own plugin that redirects WP feed to FB automatically, you can find it in FB. | What is the difference between feeds served by my WordPress install vs feeds served by FeedBurner? | wordpress |
I am using wordpress Multisite installation . 1)I want to run my website faster .Especially the main site.There are near about 50 plugins .I want to exclude many of these plugins on Main site and activate to other sub-sites.Could any body tell me how to do it? I have other three questions related to plugins on multisite installation: 2)Is there any chance for too much load on server or trouble loading pages if I Use 50 + plugins? 3)For two months I installed many plugins and un-installed them .Now i doubt that if the traces of these deleted plugins affect the server load. Is that true? If so how can I get rid of them ? 4)Some of the plugins would be activated on some sub-sites and active on some other sub-sites.So does the plugins on the sub-sites which are not active affect the server load? Thanks in Advance ! | I only recently started to poke multisite, as far as I understand you activate plugins per-site by activating theme in that site's admin area. You can switch between backend of different sites in <code> Super Admin > Sites > (hover cursor on site) > Backend </code> . Server load is not about quantity of plugins, but quality and performance specific of plugins used, amount of page views and caching. You can try plugin like Clean Options to check for leftover settings, but it is still manual work to properly determine and safely remove options. Leftover database tables are even more of a mess. Inactive plugins are not processed in any way. WordPress stores information about active plugins in database and only loads those on the list. Rest are merely ignored files on hard drive when inactive. | Exclude plugins on Main site on Multisite installation? | wordpress |
To simplify the Media Library layout to users when uploading an image, sometimes i hide the following fields: <code> function myAttachmentFields($form_fields, $post) { if ( substr($post->post_mime_type, 0, 5) == 'image' ) { $form_fields['image_alt']['value'] = ''; $form_fields['image_alt']['input'] = 'hidden'; $form_fields['post_excerpt']['value'] = ''; $form_fields['post_excerpt']['input'] = 'hidden'; $form_fields['post_content']['value'] = ''; $form_fields['post_content']['input'] = 'hidden'; $form_fields['url']['value'] = ''; $form_fields['url']['input'] = 'hidden'; $form_fields['align']['value'] = 'aligncenter'; $form_fields['align']['input'] = 'hidden'; $form_fields['image-size']['value'] = 'thumbnail'; $form_fields['image-size']['input'] = 'hidden'; $form_fields['image-caption']['value'] = 'caption'; $form_fields['image-caption']['input'] = 'hidden'; } return $form_fields; } add_filter('attachment_fields_to_edit', 'myAttachmentFields'); </code> Question: How do I hide the Insert into post button and the Set image text link. Thanks in advance | Jose, give this a shot and see if that's the kind of thing you had in mind.. EDIT: Done a little bit of testing and copying of core code to archieve this, but i think the new example i've added below should do what you've described, remove the buttons, "Insert into Post", etc..., but keep a delete link. I've left the original example i provided because it may be useful to someone. New Example Remove buttons, but keep a delete link <code> function myAttachmentFields($form_fields, $post) { // Can now see $post becaue the filter accepts two args, as defined in the add_fitler if ( substr( $post->post_mime_type, 0, 5 ) == 'image' ) { $form_fields['image_alt']['value'] = ''; $form_fields['image_alt']['input'] = 'hidden'; $form_fields['post_excerpt']['value'] = ''; $form_fields['post_excerpt']['input'] = 'hidden'; $form_fields['post_content']['value'] = ''; $form_fields['post_content']['input'] = 'hidden'; $form_fields['url']['value'] = ''; $form_fields['url']['input'] = 'hidden'; $form_fields['align']['value'] = 'aligncenter'; $form_fields['align']['input'] = 'hidden'; $form_fields['image-size']['value'] = 'thumbnail'; $form_fields['image-size']['input'] = 'hidden'; $form_fields['image-caption']['value'] = 'caption'; $form_fields['image-caption']['input'] = 'hidden'; $form_fields['buttons'] = array( 'label' => '', 'value' => '', 'input' => 'html' ); $filename = basename( $post->guid ); $attachment_id = $post->ID; if ( current_user_can( 'delete_post', $attachment_id ) ) { if ( !EMPTY_TRASH_DAYS ) { $form_fields['buttons']['html'] = "<a href='" . wp_nonce_url( "post.php?action=delete&amp;post=$attachment_id", 'delete-attachment_' . $attachment_id ) .
