I have a plugin that expects there to be a default "uncategorized" category with ID=1. I've inadvertantly deleted the uncategorized category. Is it possible to recreate the category as ID=1? When I look at a default WP install, I see that the table "wp_terms" has uncategorized as the first record with id 1. It also appears that the "wp_term_relationships" and "wp_term_taxonomy" tables are in play in this regard. How would one go about recreating this category? | You need 3 steps: 1.Creating a term in wp_terms with ID is 1 2.Insert a term_taxanomy into wp_term_taxonomy with term_id is 1, and taxonomy must be category 3.Insert a term_relationships into wp_term_relationships with object_id is 1 and term_taxonomy_id is 1 Run below code in PHPMYADMIN to re-create this category! <code> INSERT wp_terms(term_id, `name`, slug) VALUES (1, 'Uncategorize', 'uncategorized'); INSERT wp_term_taxonomy(term_taxonomy_id, term_id, taxonomy, parent) VALUES (1, 1, 'category', 0); INSERT wp_term_relationships(object_id, term_taxonomy_id, term_order) VALUES (1, 1, 0); </code> | Default category got deleted.

Is there anyway to disable custom dragging and sorting of the posting fields in admin? From time to time, the fields gets dis-ordered, and I have to sort them back to the way I want it, witch is kinda annoying. I want this also because I'm going to have other editors on the site, and I want a standardized order for everybody. I also want the excerpt-field to be above the content-field. Is all this possible? | I can answer the last part: "I also want the excerpt-field to be above the content-field. Is all this possible?" The only way to move anything above the content field is via JavaScript--there are no php hooks or filters up there. It's kind of a lame workaround because you can usually see (visually) the jump as the fields reorder. But AFAIK it's the only way to do this. <code> jQuery(document).ready( function($) { // On DOM ready move the excerpt field above the WYSIWYG field if( document.getElementById('postdiv') && document.getElementById('postexcerpt') ) { jQuery('#postexcerpt').insertBefore('#postdiv'); } else if( document.getElementById('postdivrich') && document.getElementById('postexcerpt') ) { jQuery('#postexcerpt').insertBefore('#postdivrich'); } }); </code> | Default, locked sorting of posting fields | wordpress |

I like to have a clean blog, and I also like that comments that are replies to other comments actually are replies to other comments.

On the right rail here: http://www.julianamaeberger.com/soma/sample-testimonial-3/ I am showing a random post "Testimonial". Below that I am showing all featured images for the category "Testimonial" so that you can flip through the images and choose where you want to go next. I want to highlight the image that is related to the content above, but can't figure out how to do it. This is my first time building templates, so I may be going about it the wrong way. Any help in the right direction would be much appreciated. Here is the code for the right rail: <code> <div class="rightcolumn"> <div class="testimonial"> <h3>Testimonials</h3> <?php $postslist = get_posts('category_name=testimonial&numberposts=1&orderby=rand'); foreach ($postslist as $post) : setup_postdata($post); ?> <?php the_content(); ?> <?php endforeach; ?> </div> <div class="carousel default"> <div class="jCarouselLite"> <ul class="portfolio"> <?php $postslist = get_posts('category_name=testimonial&numberposts=-1&order=DES'); foreach ($postslist as $post) : setup_postdata($post); ?> <li> <?php the_post_thumbnail( 'nav' ); ?> </li> <?php endforeach; ?> </ul> </div> <script type="text/javascript"> $(".default .jCarouselLite").jCarouselLite({ btnNext: ".default .next", btnPrev: ".default .prev", visible: 3, scroll: 3, speed:100 }); </script> </div> </div> </code> | How you want to highlight this image is specific to your layout, but it probably involves setting a class to the <code> <li> </code> surrounding it? You can do this by comparing the ID of the post you have displayed with the ID of the post of which you are showing the thumbnail. In your first loop you save the ID: <code> $current_testimonial_id = get_the_ID(); </code> In your second loop you compare it to the current thumbnail: <code> <li <?php if ( get_the_ID() == $current_testimonial_id ) { echo ' class="highlighted"'; } ?>> </code> A quick tip if you are working with multiple loops: most template functions accept post ID parameters, so you don't have to use the <code> setup_postdata() </code> function which sets some global variables. This is handy if you need the "main" post query again after your extra loop. So the following code works just a well for the second loop: <code> <ul class="portfolio"> <?php $testimonials = get_posts('category_name=testimonial&numberposts=-1&order=DESC'); foreach ($testimonials as $testimonial) : ?> <li <?php if ( $testimonial->ID == $current_testimonial_id ) { echo ' class="highlighted"'; } ?>> <?php echo get_the_post_thumbnail( $testimonial->ID, 'nav' ); ?> </li> <?php endforeach; ?> </ul> </code> | How to show a featured image as current? | wordpress |
I'd like to have my header banner change every day, chosen (e.g. randomly) from a list/folder of images. So far I only found plugins that select a random banner per post or per page view, neither is what I want. Do you know of a plugin, or any other way? Edit: Example. I'm adding a folder to my wordpress installation. This folder contains some header images. Every 24 hours, an random image is chosen from this folder and becomes the header image for 24 hours, until another random image is chosen. Actually, I don't care how exactly the image is chosen - I'm fine with rotating through all images in the folder as well. The only thing I care about is that the chosen image stays there for 24 hours. Basically it's the same as if I were picking a new header image manually every day. | <code> <div id="header"> <?php mt_srand((int)date('z')); $headers=glob(PATH_TO_FILES .'/*.jpg'); $header=mt_rand(0,count($headers)-1 ); ?> <img id="header-image" `src="<?php echo URL_TO_FILES . '/'.basename($headers[$header]); ?>" alt="header" /> </div> </code> replace your current header with this. I will of course help you implement this further if you need help.

I am looking for a wordpress plugin that allows my users to customize which posts are appearing on the home page. The users should have a settings page where they can select which categories and tags they´d like to see posts from. Do you know if anything like that has been developed? Free or premium. | I am looking for a wordpress plugin that allows my users to customize which posts are appearing on the home page. Not sure there's any particular plugins for this, but it's certainly possible with a few functions. The users should have a settings page where they can select which categories and tags they´d like to see posts from. Easier than providing a settings page that's seperate from the profile page, i'd actually suggest adding a couple of new fields to the user's profile page, you can call the section home preferences or whatever you like. Example follows... Step 1 - Add custom fields to the user profile page Here i took the same approach as Mike did when answering: stackexchange-url ("How to add custom form fields to the user profile page"), firing on two actions to account for user profile saves and admin user edits. <code> add_action( 'show_user_profile', 'home_prefs_profile_fields' ); add_action( 'edit_user_profile', 'home_prefs_profile_fields' ); function home_prefs_profile_fields( $user ) { $um = get_user_option( 'taxonomy_selection', $user->ID ); $tags = ( isset( $um['post_tag'] ) ) ? $um['post_tag'] : array(); $cats = ( isset( $um['categories'] ) ) ? $um['categories'] : array(); ?> <div id="home-prefs"> <h3>Home Preferences</h3> <table class="form-table"> <tr> <th> <label for="tax_input[post_tag]">Tags</label><br /> <span class="description">Choose which tags you want to display on the home page.</span> </th> <td> <ul id="tag-checklist"> <?php wp_terms_checklist( 0, array( 'taxonomy' => 'post_tag', 'selected_cats' => $tags ) ); ?> </ul> <br class="clear" /> <hr /> </td> </tr> <tr> <th> <label for="post_category">Categories</label><br /> <span class="description">Choose which categories you want to display on the home page.</span> </th> <td> <ul id="category-checklist"> <?php wp_category_checklist( 0, 0, $cats, false ) ?> </ul> </td> </tr> </table> </div> <?php } </code> Information on the term and category checklists can be found in the source(no docs yet). http://core.trac.wordpress.org/browser/tags/3.0.2/wp-admin/includes/template.php#L217 Step 2 - Handle saving data on profile/user update Again, two actions, depending on whether it's a user saving profile changes or another user making changes to another user's profile. <code> add_action( 'personal_options_update', 'save_home_prefs' ); add_action( 'edit_user_profile_update', 'save_home_prefs' ); function save_home_prefs( $user_id ) { if ( !current_user_can( 'edit_user', $user_id ) ) return false; $data = array(); if( isset( $_POST['tax_input'] ) ) { foreach( $_POST['tax_input'] as $taxonomy => $term_ids ) if( !taxonomy_exists( $taxonomy ) ) continue; else $data[$taxonomy] = array_map( 'intval', $term_ids ); } if( isset( $_POST['post_category'] ) ) $data['categories'] = $_POST['post_category']; update_user_meta( $user_id, 'taxonomy_selection', $data ); } </code> NOTE: It wouldn't hurt to add further sanitization to the above. Step 3 - Adjust the CSS Indent children terms, float the main list items, so busy taxonomies don't consume so much height. <code> add_action( 'admin_print_styles-user-edit.php', 'tax_checklist_css' ); add_action( 'admin_print_styles-profile.php', 'tax_checklist_css' ); function tax_checklist_css() { ?> <style type="text/css"> .children { text-indent: 20px } #tag-checklist li { float:left;width:30% } #category-checklist li { float:left;width:30% } #category-checklist li li { float:none;width:auto } </style> <?php } </code> NOTE: 30% width on the list items basically gives you the appearance of 3 columns of terms, you're welcome to adjust the CSS to suit. This could also just as easily be turned into an enqueue, which will provide some level of caching, inline CSS is quicker to test is all... ;) Step 4 - Filter home query based on user prefs Add a filter onto home queries based on user configured settings for tags and categories. <code> add_action( 'pre_get_posts', 'do_user_post_selection' ); function do_user_post_selection( $query ) { if( !is_home() || !is_user_logged_in() ) return; if( isset( $query->query_vars['post_type'] ) && ( 'nav_menu_item' == $query->query_vars['post_type'] ) ) return; if( 1 < did_action('wp') ) return; global $current_user; $tax_selection = get_user_option( 'taxonomy_selection', $current_user->ID ); if( empty( $tax_selection ) ) return; if( isset( $tax_selection['categories'] ) && ( is_array( $tax_selection['categories'] ) ) && ( !empty( $tax_selection['categories'] ) ) ) $query->set( 'category__in', $tax_selection['categories'] ); if( isset( $tax_selection['post_tag'] ) && ( is_array( $tax_selection['post_tag'] ) ) && ( !empty( $tax_selection['post_tag'] ) ) ) $query->set( 'tag__in', $tax_selection['post_tag'] ); return; } </code> NOTE: You don't have to use a <code> pre_get_posts </code> filter, you could use <code> parse_query </code> or pass values into a <code> WP_Query </code> object, i personally just find the chosen hook easy to use(and it's what i'm use to using). UPDATE: Move the home prefs elements to the top of the profile page. <code> function move_prefs() { ?> <script type="text/javascript"> jQuery(document).ready(function($){ $('#home-prefs').prependTo('#your-profile'); $('input[type=checkbox]').attr('disabled',false); }); </script> <?php } add_action( 'admin_head-user-edit.php', 'move_prefs' ); add_action( 'admin_head-profile.php', 'move_prefs' ); </code> NOTE: There's a slight HTML update to the <code> home_prefs_profile_fields </code> function also required, i've updated the function as appropriate in Step 1 . RE: Checkboxes showing disabled from subscribers(see comments). The reason this occurs is due to a capability check in the term checklist functions, these functions are typically used on post creation type screens, so expect the user to have the capability to assign terms to a post(or type), this obviously doesn't apply to this particular case so we can safely remove the disabled attribute from them(jQuery above has been ammended with the appropriate change). Hope that helps... :) | Filter index page plugin | wordpress |
I would like to change the order in which users are displayed in the admin. At the moment it seems that they are order by the username. I think I have found the right place in the wp-admin/users.php, which is around line 187: <code> ORDER BY user_login"); </code> I am not 100% sure if this is right as I don't know much about the code. Could anyone confirm if I am in the right place and what I should do to change the order.

You can call your Twitter function above this and it should work. You'd be better off using a theme framework with some custom hooks because hooking into <code> the_content </code> in this way can get very buggy very fast depending on what other filters/hooks your theme and plugins are using to modify <code> the_content </code> . I don't know why it happens, I just know that it does. | write in functions.php | wordpress |
How difficult would it be to add an option for "nofollow" to the Link editor's existing "Link Relationship(XFN) options list? Alternately, or better yet, in addition, add an item to the "Bulk Actions" listing called "Make links no follow" that would make all selected links rel="nofollow". I'd like to add this feature to my theme's functions.php | Alternatively you can undo the code that disables the relationship box by re-pointing the enqueue to the xfn.js script.. First create a modified version of that script, like so.. <code> jQuery(document).ready( function($) { //$('#link_rel').attr('readonly', 'readonly'); $('#linkxfndiv input').bind('click keyup', function() { var isMe = $('#me').is(':checked'), inputs = ''; $('input.valinp').each( function() { if (isMe) { $(this).attr('disabled', 'disabled').parent().addClass('disabled'); } else { $(this).removeAttr('disabled').parent().removeClass('disabled'); if ( $(this).is(':checked') && $(this).val() != '') inputs += $(this).val() + ' '; } }); $('#link_rel').val( (isMe) ? 'me' : inputs.substr(0,inputs.length - 1) ); }); }); </code> Save as xfn.js and place into a plugin's folder or the current theme's folder. NOTE: It's a direct copy of the original(existing) script enqueued by WordPress, i've left original code that sets the rel input to read-only so you can see what's been changed(one line). Then add this to your plugin code, or theme's functions.php, and uncomment the appropriate line in the code sample.. <code> function switch_xfn_src( $src, $handle ) { if( 'xfn' == $handle ) //$src = plugins_url( '/xfn.js', __FILE__ ); // For use inside plugin //$src = get_bloginfo( 'stylesheet_directory' ) .

I'd like to add some code to my plugin populate a specific sidebar (if it exists) with a text widget containing preset content. Assuming that the sidebar I'm trying to preset is referenced by ID as "my-widget", how would I preset the content's of that widget with a text widget containing the text "Hello World"? | You need to do this in two steps. First create the actual widget. Find a widget ID that does not exist, and toss in an extra entry in (off the top of my head) the widget_text option, which corresponds to the text widget config.

I have a custom post type that I want to display the page you are on and how many pages total in this manner "Page 3 of 5" (meaning you are on page 3 of a 5 page post).

Running IIS 7 and WP 3.0. I've got a web.config that has the necessary rewrite rules to make permalinks work, and they're working. However, if I point to n-nexus.realtimepublishers.com/content/?feed=rss2, the server first generates an HTTP 404. Weirdly, it then delivers the RSS feed. The problem is that the initial 404 makes things like FeedBurner and Safari barf; Firefox displays the feed properly (you can see the 404 error in Live HTTP Headers, though).

I display a random post loop on a page. I'd like to put a "refresh" link to refresh the content of the loop via ajax. Is this possible? This is my loop if it helps: <code> <ul id="content-inner" class="thumb-grid clearfix"> <?php query_posts('posts_per_page=20&orderby=rand'); ?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <li> <a href="<?php the_permalink(); ?>"> <img src="<?php echo $my_image_url = get('thumbnail'); ?>" alt="" /> <span class="title"><?php the_title(); ?></span> <span class="feat"><?php $articletags = strip_tags(get_the_tag_list('',', ',''));echo $articletags;?></span> </a> </li> <?php endwhile;?> <?php endif; ?> <?php wp_reset_query(); ?> </ul> </code> | Shouldn't be too tricky. First: create a javascript file and add this: <code> jQuery(document).ready(function($){ $('#refresh-links-id').click(function(e){ e.preventDefault(); $.post(ajaxurl,{action:'jpb_random_loop'}, function(data){ $('#content-inner').fadeOut(250).empty().append( data ).fadeIn(250); }); }); }); </code> Save that file in your theme directory somewhere (could be in a subdirectory too). For this to work, the refresh link should not be inside <code> ul#content-inner </code> . Pretty basic jQuery post call, though. Next, add this to your theme's <code> functions.php </code> file: <code> function jpb_template_redirect(){ if( <conditions under which this javascript should execute> ){ wp_enqueue_script( 'random-loop', '<url to the javascript file above>', array( 'jquery' ), '1.0' ); } } function jpb_random_loop_cb(){ query_posts('posts_per_page=20&orderby=rand'); if (have_posts()) : while (have_posts()) : the_post(); ?> <li> <a href="<?php the_permalink(); ?>"> <img src="<?php echo $my_image_url = get('thumbnail'); ?>" alt="" /> <span class="title"><?php the_title(); ?></span> <span class="feat"><?php $articletags = strip_tags(get_the_tag_list('',', ',''));echo $articletags;?></span> </a> </li> <?php endwhile; endif; die(); } add_action( 'template_redirect', 'jpb_template_redirect' ); add_action( 'wp_ajax_jpb_random_loop', 'jpb_random_loop_cb' ); add_action( 'wp_ajax_nopriv_jpb_random_loop', 'jpb_random_loop_cb' ); </code> That will tie everything together.

Couldn't find anything in the related questions, so here goes: I have a post which, when viewed on the site, is returning a redirect loop. The error page is showing an address for the post that originated when the post was added to a category that was subsequently deleted. www.macrowikinomics.com/innovation-communities/business-economics/will-facebook-be-your-crm-provider is the correct address, but it keeps redirecting to www.macrowikinomics.com/innovation-communities/guest-authors/will-facebook-be-your-crm-provider/. Guest-authors was the old category obviously. My thought was it might be the automatic canonical URL redirect feature. Despite adding the disable canonical url function (src = Mark Jaquith) it continues to redirect to this old address. Cleared the cache and cookies and still it goes. Tried it in another browser and I continue to get the error. There is also no cache plugin running on the site. Could it be something in the pretty permalinks? They're using the format /%category%/%postname%/ Many thanks for any thoughts you can provide. | Do you use a plugin called Redirection? It has a setting that will automatically create redirects when a post permalink is changed, and if the post is renamed and then changed back to the original name, you get a loop.

All right, so we're probably all familiar with the typical way to ensure that your main CSS file is refreshed when you load the page (busting the browser cache), right? <code> <link rel="stylesheet" type="text/css" media="all" href="<?php echo get_stylesheet_uri(); echo '?'.filemtime( get_stylesheet_directory() . '/style.css'); ?>" /> </code> I need to do the same thing on another CSS file. Yes, my style.css file has its own set of @import "css/myFile.css" which are working fine, but humor me, if you will. So, back to header.php, right after that first link, and before the call to wp_head(): <code> <?php $cssFile = get_stylesheet_directory_uri().'/css/other.css'; ?> <link rel="stylesheet" type="text/css" media="all" href="<?php echo $cssFile; echo '?'.filemtime($cssFile); ?>" /> </code> And this leads to a warning (as part of the href attribute of the link when the browser gets the page): Warning: filemtime(): stat failed for http://localhost/wordpress/wp-content/themes/my_theme/css/other.css the path to the file seems to be built correctly (and the other.css file is there), but filemtime (stat, actually) fails on it. How come? Other recommended ways to include the 'latest' version of a CSS file other than style.css? Should I go with wp_register_style instead? If so... how can I tell wp_register_style to bust the browser cache (ie: get me the latest version of the css file, even if the browser has it cached)?

I am trying to modify the support links under the help section (Contextual help).I want to replace these Documentation on Using Themes and Support Forums with my own .So I removed the links in wp-admin folder from many pages under admin section .But for plugin pages,I can't able to find the files to remove. Is there any way to replace or remove the links site wide ? | But for plugin pages,I can't able to find the files to remove. For dealing with plugin/registered pages that you won't necessarily know the hooks for, something like this will work... <code> add_action( 'admin_head', 'set_plugin_help_text'); function set_plugin_help_text() { global $_registered_pages; if( !empty( $_registered_pages ) ) foreach( array_keys( $_registered_pages ) as $hook ) add_contextual_help( $hook, "Your generic plugin page help text" ); } </code> NOTE: I purposely didn't use the contextual help action(as used in RodeoRamsey's answer) because it doesn't work for the above approach(so it wasn't without reason, i notice the other answer got more votes and i presume that *may* be why). Of course do note that the custom-background, custom-header and the theme editor pages under the themes menu also count as registered pages, so they'll naturally be effected by the above code (you can always factor some exclusion code into the above to deal with that though). EDIT BELOW: Additionally if you want to modify the help text for pages that aren't registered, ie. those that exist physically in WordPress and are used by WordPress, you can use the following approach. <code> add_filter( 'contextual_help_list', 'wp_help_info_replace', 10000000, 2 ); function wp_help_info_replace( $help, $screen ) { if( in_array( $screen->id, array( 'post', 'edit-post' ) ) ) $help[$screen->id] = 'Simple example help text'; return $help; } </code> In the above example i'm targetting edit.php and post-new.php , be sure to pay attention to the array values that refer to the screen ID, this value does not match what you'd typically expect to see as the pagehook, i would suggest echo'ing out the screen ID for screens where you're unsure about what the ID may be. | Modify links under 'help section'? | wordpress |

I have a function that defines a custom field on a post type. Say the field is "subhead". When the post is saved, I want to do some validation on the input, and display an error message on the post edit screen if necessary. Something like: <code> // Handle post updating function wpse_update_post_custom_values($post_id, $post) { // Do some checking... if($_POST['subhead'] != 'value i expect') { // Add an error here $errors->add('oops', 'There was an error.'); } return $errors; } add_action('save_post','wpse_update_post_custom_values',1,2); </code> I'm trying to hook this to the save_post action, but I can't figure out how to handle errors. There doesn't appear to be an error object passed into the function, and if i create my own WP_Error obj and return it, it's not respected by whatever mechanism spits out errors on the post edit page. I currently have an on-page error message inside my custom meta box, but this is less than ideal--I'd rather have a big, red, up-at-the-top error like WP normally displays. Any ideas? UPDATE: Based on @Denis' answer, I tried a few different things. Storing errors as a global didn't work, because Wordpress does a redirect during the save_post process, which kills the global before you can display it. I ended up storing them in a meta field. The problem with this is that you need to clear them out, or they won't go away when you navigate to another page, so I had to add another function attached to the admin_footer that just clears out the errors. I wouldn't have expected that error handling for something so common (updating posts) would be this clunky. Am I missing something obvious or is this the best approach? <code> // Handle post updating function wpse_5102_update_post_custom_values($post_id, $post) { // To keep the errors in $errors = false; // Do some validation... if($_POST['subhead'] != 'value i expect') { // Add an error here $errors .= 'whoops...there was an error.'; } update_option('my_admin_errors', $errors); return; } add_action('save_post','wpse_5102_update_post_custom_values',1,2); // Display any errors function wpse_5102_admin_notice_handler() { $errors = get_option('my_admin_errors'); if($errors) { echo '<div class="error"><p>' . $errors .

I've been bashing my head against my desk all afternoon trying to figure this out. I've got a custom post type all set up, with hierarchical set to "true" and I can assign parents and see the relationship in the back end. Which is great. Except I want to list the children (and siblings) of my special new post type. I found this code <code> <?php if($post->post_parent) $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0"); else $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0"); if ($children) { ?> <ul> <?php echo $children; ?> </ul> <?php } ?> </code> which works perfectly when I put it into a page template for pages.

My question: Is there a better mechanic in Wordpress to solve the problem I'm presenting? I'm a developer, so I see this readily as several tables in a custom CMS that I'd just whip up over the weekend ("6 hours tops, promise!") that would quickly get out of hand, so I'd love to leverage my knowledge of WP to get this done more efficiently. | you could make category for each family (name), and a (sub)category for each region, and then assign custom templates to each category using category templates plugin . or - in case you want to use pages instead of posts/categories - then you don't need this plugin but instead just create additional page templates for each family.. both ways will give you a box when you go to create new post / new page which will be on the right side - and there you will be able to choose a custom template for each post/page. for gallery, I recommend NextGEN - you can create separate gallery for each family, and assign them (gallery categories) to post categories or pages. NextGEN will give you lots of options. | Approach to creating a site with this structure | wordpress |

After inspection I found out that the external content (so far just html advertising different kinds of drugs, no scripts) was in the static pages created by w3 total cache.

I have just changed the theme on my blog, and because of a small page width, it breaks the layout. Most of my earlier images (attached in posts) are around 600px in width, and now I need to resize all of them them proportionately to 450px. How do I resize them all at one shot? Is there a plugin for this? P.S.: Writing a CSS rule is a good option, and I've already done that. But I figure resizing the images would also knock off the download overhead for each page! | I asked stackexchange-url ("a similar but broader question"), and I still need to research and write a complete answer. In the meantime here are some pointers that might help you: I wrote stackexchange-url ("a set of plugins that resizes all images to the size used in the editor"). It works by converting <code> <img src="image.jpg" width="200" height="400"/> </code> to <code> <img src="image-200x400.jpg" width="200" height="400"/> </code> ( Resize img tags ) and catching and generating those missing intermediate sizes on request ( On-Demand Resizer ). You should be able to do the first part in bulk, and then let the second plugin handle the new images. It also works with partial information: <code> image-200x.jpg </code> will return a proportionally-resized image 200 pixels wide. Regenerate Thumbnails indeed re-creates images at different sizes, but I don't think it also updates your post content to refer to these images? Even worse, if it deletes the old intermediate sizes, your post will still reference the now non-existing <code> image-600x400.jpg </code> instead of <code> image-450x300.jpg </code> . | Resizing all images | wordpress |

It's already everything in there you might need / can imagine. If you don't want to make use of 3.1 but 3.0, use the 3.1 code as the example you're asking for. The user bar is located in admin-bar.php and class-wp-admin-bar.php . Your theme needs to support <code> admin-bar </code> and the code takes care on it's own by point-cutting the <code> wp_head </code> hook - which you should have in your theme in any case. Script and CSS styles are named 'admin-bar' as well. So it's basically copying over the files to your site, enabling theme support for it and if there are some 3.1 only functions used therein, work around those. You can additionally move those files to your theme, rename functions and classes to reflect your namespace to have this a bit more separated. A benefit to make use of that is that your site will be compatible when updating to 3.1. | User bar above logotipo? | wordpress |

I've tried to explain the benefits of WordPress to others; comparing it to static sites is easy, as (most) everything can be done online with WP.

Call me stupid but I coudn't figure out how to do it. For text input I would just: <code> <input type="text" name="option_name" value="<?php echo get_option( 'option_name' ); ?>" /> </code> and then hook it into workdpress using <code> register_setting() </code> . I could then get its value thru <code> get_option('option_name') </code> . How should I do that with checkboxes and radio buttons? | I tend to store multiple options as an array, so i'd have something like this.. <code> <?php $options = get_option( 'myoption' ); ?> <input type="checkbox" name="myoption[option_one]" value="1"<?php checked( 1 == $options['option_one'] ); ?> /> <input type="checkbox" name="myoption[option_two]" value="1"<?php checked( 1 == $options['option_two'] ); ?> /> </code> However it does depend how the callback function that sanitizes the incoming data deals with the saved value(the callback you should be defining as the third parameter of <code> register_setting </code> ). Personally when i'm dealing with checkboxes I don't set the array key, where as others may choose to set the key to 0(or whatever instead)... So my code actually tends to look like this.. <code> <?php $options = get_option( 'myoption' ); ?> <input type="checkbox" name="myoption[option_one]" value="1"<?php checked( isset( $options['option_one'] ) ); ?> /> <input type="checkbox" name="myoption[option_two]" value="1"<?php checked( isset( $options['option_two'] ) ); ?> /> </code> If i'm only dealing with checkboxes my sanitization callback will look something along the lines of.. <code> public function on_option_save( $options ) { if( !is_array( $options ) || empty( $options ) || ( false === $options ) ) return array(); $valid_names = array_keys( $this->defaults ); $clean_options = array(); foreach( $valid_names as $option_name ) { if( isset( $options[$option_name] ) && ( 1 == $options[$option_name] ) ) $clean_options[$option_name] = 1; continue; } unset( $options ); return $clean_options; } </code> Ripped that straight from one of my plugin classes(a plugin with only checkbox options), but it's not code you can expect to work if you copy, it's there for illustration only.. For radios, if you're not using multiple selection it goes something like this.. <code> <?php $options = get_option( 'my_option' ); ?> <input type="radio" name="myoption[option_three]" value="value1"<?php checked( 'value1' == $options['option_three'] ); ?> /> <input type="radio" name="myoption[option_three]" value="value2"<?php checked( 'value2' == $options['option_three'] ); ?> /> </code> NOTE: It would of course to be wise to check the key is set before comparing against it's value (i've left that out of the above to keep it short). Did the above help? If not, just let me know what needs clarifying... (or what i'm missing).. RE: <code> checked() </code> You can find where the function is defined(in WordPress) here. http://core.trac.wordpress.org/browser/tags/3.0.2/wp-includes/general-template.php#L2228 The first parameter is basically a conditional statement, and the second parameter(if you want to define it) is what to check against. The default value to compare against is TRUE ... so if were to do <code> checked( 1 == 1, true ) </code> i'd be checking if 1 == 1 is equal to true. If the conditional hits a match, then you get <code> checked="checked" </code> returned to you..

How can I extend the functions of the WordPress 3.1 admin bar in my plugins? I am looking for specific hooks and filters to use in adding links or other features to the admin bar. A good example of what has already been done is the Yoast WordPress SEO (Wordpress Plugin). Currently there is no documentation available on extending the admin bar. According to The Codex there are two filters to turn it off or not show it: <code> no_admin_bar() </code> & <code> show_admin_bar() </code> | Yoast's plug-in is actually a very good example if all you want to do is add menus. Basically, the admin bar is just an alternate set of links to the same plug-in admin pages you have in the sidebar. To add the top-level SEO menu, Yoast does the following: <code> $wp_admin_bar->add_menu( array( 'id' => 'wpseo-menu', 'title' => __( 'SEO' ), 'href' => get_admin_url('admin.php?page=wpseo_dashboard'), ) ); </code> This adds a menu named "wpseo-menu" to the admin bar and directs users to the plug-in's dashboard when they click the link. Child links are added in a similar fashion: <code> $wp_admin_bar->add_menu( array( 'parent' => 'wpseo-menu', 'id' => 'wpseo-kwresearch', 'title' => __( 'Keyword Research' ), '#', ) ); </code> You just specify the "parent" of the menu you're adding. Then you can go as deep as you need to, calling <code> $wp_admin_bar->add_menu() </code> when you need to and specifying the appropriate information. For reference, the variable, <code> $wp_admin_bar </code> is an instance of the class <code> WP_Admin_Bar() </code> within WordPress. It has several different methods and properties, but the one you're most interested in here is, obviously, <code> add_menu() </code> . This method accepts certain parameters: title - default false href - default false, parent - default false - pass the ID value for a submenu of that menu id - defaults to a sanitized title value. meta - default false - array of any of the following options: <code> array( 'html' => '', 'class' => '', 'onclick' => '', target => '' ); </code> But the rest of the <code> WP_Admin_Bar() </code> class is pluggable. It just depends on what exactly you're trying to do and how you want to do it.

In the event of multiple categories assigned to a post, then it would simply take the first one.

One way to do this is to put all the default images in a directory and name them for the categories, eg. news.jpg and reviews.jpg then instead of using <code> <?php the_post_thumbnail( 'thumbnail' ); ?> </code> to display your Featured Image you'd use this: <code> <?php if ( (function_exists('has_post_thumbnail')) && (has_post_thumbnail()) ) { the_post_thumbnail('thumbnail'); } else { ?> <img src="whatever/directory/<?php $category = get_the_category(); echo $category[0]->cat_name; ?>.jpg" /> <?php } endif; } ?> </code> So in this example above if the post is in the news category and your writer didn't set the Featured Image it'll default to the image stored at <code> http://www.yoursite/whatever/directory/news.jpg </code> . | Can I set a default featured image for a category? | wordpress |

So instead of <code> /category/sub-category/article.html/attachment/image </code> you can go to <code> /?attachment=image </code> . The only case when this "breaks down" is when you go to <code> /category/sub-category/article.html?attachment=image </code> , because WordPress gets confused: it tries to query for a post and an attachment at the same time. However, this is very simple to handle: check for the request, and if it is an attachment remove the other parameters. <code> add_action( 'parse_request', 'wpse5015_parse_request' ); function wpse5015_parse_request( $wp ) { if ( array_key_exists( 'attachment', $wp->query_vars ) ) { unset( $wp->query_vars['name'] ); unset( $wp->query_vars['year'] ); unset( $wp->query_vars['monthnum'] ); } } </code> Now you only have to change the generated attachment URLs.

Can someone explain to me please how exactly Bad Behavior works? On their official site, they say that it uses HTTP headers, IP, and meta fingerprinting - but I would like some specifics on its mechanisms, not a simple description. To be more precise - how does it profile malicious activity (what kind of activity triggers "falls outside the bounds of a normal human browsing the web"), what does it look for in HTTP headers and metadata? Anyone? thanks! =) PS for mods - please could you add 'bad-behavior' tag? thanks | Bad Behavior does two things: It checks the HTTP request and sees if it is as per the standard or not. Usually spammers don't write their scripts so well as to be fully compliant with the HTTP standard. Bad Behavior can make out poorly scripted HTTP requests from properly scripted ones (which would be sent by genuine visitors using well-designed Web browsers, etc.), and then blocks the improper HTTP requests. It checks the IP address of the machine that sent the HTTP request against a database of known spammer IPs. If the IP address matches one in the database, Bad Behavior will block the request before it gets to the Wordpress engine, thereby conserving your CPU and bandwidth. The spammer that sent the HTTP request will get nothing in the response. This is not done by default - to enable this functionality, you need to be a member of Project HoneyPot, as you rightly mentioned. When you sign up for this Project, you will get a "key" that you need to enter in the plugin settings page to enable this functionality. Hope this helps.

i migrated a wordpress site from one domain to another. I still have images and links that seem to be pointing to my old domain name. where can i get a list of all places in wordpress that hardcode or has the domain name in it. the only place i saw was in the database in the wp_posts table in the guid column. where else should i be looking? | Don't worry about changing the guid, you'll be fine if you never update that field. The main places you'll need to update are in the post_content column of wp_posts (for links and images), and in the wp_options table (for widget data). Before you do any database replacing, though, read through this thread: stackexchange-url ("Easily Move a WordPress Install from Development to Production?") There are some helpful tips there, and there are plugins that will do most of the work for you. | how do i find out why links point to my old domain | wordpress |

I have inherited a situation where our team supports over 100+ separate WordPress installs for various clients. I am looking to make the whole process a bit more efficient. For all of those in a similar situation of managing a large number of Wordpress installs: Are there any tools or techniques that are helpful? The thought of migrating all of these to 3.0.2 by logging in or writing a script from scratch both sound particularly unappealing. | Well it depends on how/where they are hosted. If if they are hosted on different servers or the same I would still use the command line and a script file. If they all have different usernames/passwords you going to have to write a lot. Pre-planning will save you a ton of time in maintenance. First it would be best to get some data on all the sites, for instance versions. Here is an example of a script file for multiple servers, http://www.cyberciti.biz/tips/execute-commands-on-multiple-linux-or-unix-servers.html but in your case you would do something like <code> grep wp_version wp-includes/version.php </code> to get all the version info. Of course if they all have diff admin passwords you would have to include each one. An alternative would be to write a script to crawl the sites to grab the meta generator tags ( though they are sometimes disabled). I would also do a mass backup using the command line and a similar script, possibly automated to a date based dir and using an sql dump. You can then also update to the latest version for all 100+ servers using a command to run a script file. The big drawback would by incompatible plug-ins/themes or if any core code was edited, this is why I would try and gather as much data as possible to avoid any issues with keeping them up to date. I do not know of anyway to automate getting a list of active plugins though, so you might have to manually get some info and hopefully you have command line access to the sites. It might take a while to set this and and perfect it, but the benefit is that you can tell your boss it takes 2 weeks, and that will leave you with 1.9 weeks of free time. | Adminstering Large Number of Wordpress Sites | wordpress |

For setting default values for a particular post type for new posts you can use a small hack by hooking onto <code> default_content </code> (although <code> default_title </code> would also work to), like the example i gave stackexchange-url ("here"). You essentially need two functions, one to modify post objects at the time of save/insert and one to set default post object values, here's an example of the two necessary functions(again noting you can swap my save_post callback for the example already given by TheDeadMedic). <code> add_action( 'save_post', 'check_type_values', 10, 2 ); function check_type_values( $post_id, $post ) { if( $post->post_type ) switch( $post->post_type ) { case 'my_custom_type': $post->post_status = 'private'; $post->post_password = ( '' == $post->post_password ) ?

These entries are 1170 and the <code> meta_key </code> ranges from 45511 to 46788 and the last post (as in the one with the greatest ID) referred to one of these meta keys is dated almost three years ago, so I think they might have been created by some plugin which has been long forgotten now. Is there any way to find out if any plugin uses those kind of meta values? I did a search but found nothing. I'd like to know if they're safe to delete because they seem useless and also mess up the post creation page as they fill the custom field dropdown select (I had to modify the code to exclude numeric meta keys). | The best way to know which plugin was adding them is to search/grep your installation for occurrences of <code> 'wpAjax' </code> and <code> "wpAjax" </code> .

I'd like to modify the properties of a registered style(or script - same applies) before it's been loaded.

Unregister the style and register my own? - I'd then have to unregister both color schemes(classic/fresh) when i'd prefer to simply hook on and tweak the styles object before the enqueue fires. I'm pretty sure it's possible, but simply lacking the brain power to wrap my head around it right now.. (been wired in too long).. Any suggestions welcome.... ;) | Modify a registered style's path I wanted to tweak the path to one of the WordPress admin stylesheets so i could keep requests down, and because it makes little sense to include two stylesheets, when the one i'm calling redefines all the styling in the stylesheet enqueued by WordPress. The idea is basically to re-point the existing style at a different stylesheet, two hooks are appropriate <code> style_loader_src </code> <code> style_loader_tag </code> . The former provides just the stylesheet URL(or path) and the handle(that's the name the style is registered with), the latter provides the complete HTML string(and handle) for the stylesheet being included. I decided to use <code> style_loader_src </code> to switch the colors stylesheet path(src) because that's literally all i need, to adjust the path and know the current handle, so suits my needs perfectly. Example filter that changes the path to the colors stylesheet. Checks if the handle is the colors stylesheet, and updates the path when it is. <code> function switch_stylesheet_src( $src, $handle ) { if( 'colors' == $handle ) $src = plugins_url( 'my-colors.css', __FILE__ ); return $src; } add_filter( 'style_loader_src', 'switch_stylesheet_src', 10, 2 ); </code> The above filter will basically take the existing colors stylesheet output, eg. <code> <link rel='stylesheet' id='colors-css' href='http://example.com/wp-admin/css/colors-fresh.css?ver=20100610' type='text/css' media='all' /> </code> And convert it to.. <code> <link rel='stylesheet' id='colors-css' href='http://example.com/wp-content/plugins/my-plugin/my-colors.css' type='text/css' media='all' /> </code> I find this method preferable to enqueuing an additional stylesheet, it's one less requests, and there's far less CSS overrides required in whatever styling you're doing, because you're essentially hijacking that request to load your own stylesheet instead. | Is it possible to change the attributes of a registered style or script before it fires? | wordpress |

"post_votes"; $results = $wpdb->get_row( "SELECT GREATEST (up, down) FROM $table WHERE voted_post_id = $post_id" ); echo $results->up; //echo if highest value echo $results->down; //echo if highest value } </code> Then in my loop I call the function but get <code> Notice: Undefined property: stdClass::$up </code> for <code> echo $results->up; </code> and the same notice for <code> down </code> . I'm not sure what I'm doing wrong here. | I think you want to use <code> get_var() </code> , not <code> get_row() </code> - looking at the documentation , MySQL's <code> GREATEST </code> just returns a single value. <code> $results </code> will then just be the value of the greatest (be it <code> up </code> or <code> down </code> ). If you want the greatest <code> up </code> and the greatest <code> down </code> , use; <code> $wpdb->get_row("SELECT GREATEST(up) AS 'up', GREATEST(down) AS 'down' ...") </code> | greatest() function returns undefined property | wordpress |
What are the capabilities that a super-administrator has that an administrator does not have? The codex page on user capabilities does not have a list of capabilities of the super-admin. It lists only the capabilities of the administrator. | The super_admin has access to all admininstrator APIs and also the multi-site functions. If you go to the codex page, it will say so: http://codex.wordpress.org/Roles_and_Capabilities#Capability_vs._Role_Table You can find the multisite functions here: http://codex.wordpress.org/Function_Reference#Multisite_functions If you want to do a more fine-grain investigation of what it can call, I suggest you get familiar with the WP code.

( Moderator's note: The original title was: "submit button in wordpress.") I'd like to create a registration form to send an email. I've tried Contact Form 7 but I would like to use my own HTML <code> <form> </code> . I can do the entire coding but I just want to know the code for the "submit" button so that the registrations goes directly to my admin email ID as I don't think the normal HTML code for the submit button will work. Can anyone help me out in this? | Hi @ntechi: While you might be able to do something on the client with jQuery I think your best bet would be to use the Post/Redirect/Get Pattern and submit your registration form via a <code> <form method='post'> </code> action. The code after the screenshot below is a " Page Template " for a " Page " illustrates how to achieve what you've asked for with WordPress. Copy the code to your theme directory as <code> page-contact-form.php </code> (or some other name you like better) and then create a page that has template set to "Contact Form" as you see in the screenshot (note I kept the page template as simple as possible to illustrate the technique; you'll typically have a lot more code in your real live page templates): <code> <?php /* Template Name: Contact Form */ define('ADMIN_USER','mikeschinkel'); if (count($_POST)) { $admin_user = get_userdatabylogin(ADMIN_USER); $registered_email = $_POST['email']; wp_mail($admin_user->user_email, 'New Site Registration', "New Site Registration:\n\tEmail: {$registered_email}."); } ?> <?php get_header(); ?> <?php if (count($_POST)): ?> <p>Hey <?php echo $_POST['email']; ?>, thanks for registering!</p> <?php else: ?> <form method="post"> Email: <input type="text" name="email" /> <input type="submit" value="Register" /> </form> <?php endif; ?> <?php get_footer(); ?> </code> After you've created your page with the above page template it might look something like this on your external site: And this might be what it looks like after a visitor registers: | Programming WordPress to Send an Email on Registration Form Submit? | wordpress |
I've just moved a site I'm developing to WP3.1 so that I can take advantage of and start testing some of the new features. I'm especially liking the <code> has_archive </code> parameter in registering custom post types. I had a post type called 'recipes', and added this line to the args on registering it: <code> 'has_archive' => 'recipe-listings', </code> From what I understand, that should generate the rewrite rules necessary to make /recipe-listings/ be equivalent to /?post_type=recipe . However, I can't seem to get it working. The generic form http://amritafood.com/?post_type=recipe works fine, but http://amritafood.com/recipe-listings/ just goes to 404. What else do I need to do to get custom post type archives working properly? Has anyone else worked it out yet? | I asked the question too soon. And thanks to @Jan Fabry for pointing me in the right direction. In case anyone else has this problem, here's the answer. Any time the rewrite rules are changed (adding a new post type, changing the slug or the has_archive slug, etc.) you have to call <code> flush_rewrite_rules </code> once. It has to be called after the post types are registered. I put it at the very end of my function which registered the post types on 'init', visited the site once, then deleted it out. Now the site works fine. | Setting up custom post type archives in WP3.1? Any luck? | wordpress |
Guys I know this is the stupid question but need a little help, I need to put ads on my homepage as I have on my post page: These are the ads I get on my post page (i.e <code> single.php </code> ).

Which files do i edit to make the textarea for tag & cat description bigger? Or maybe there's an easier way through functions.php to save having to do it every-time i update wp?

i have a form which is displayed after every post, so i coded it in single.php, but the form is too long so i thought of putting it in jquery section, where if the user wants then he/she can click on open and the form will slide down for this purpose i used slide up/down jquery http : //api . jquery . com/slideDown/ i integrated the jquery in proper order in header.php, here is my header.php jquery code <code> <?php wp_enqueue_script("jquery"); ?> <?php wp_head(); ?> <script type="text/javascript" src="<?php bloginfo("template_url"); ?>/functions/js/jquery-1.4.4.js"></script> <script> $(document.body).click(function () { if ($("h6:first").is(":hidden")) { $("h6").slideDown("slow"); } else { $("h6").hide(); } }); </script> <?php woo_head(); ?> </code> and this is my single.php code, ` <code> <div class="post"> <p><h6> <?php echo do_shortcode("[contact-form 2]"); ?></h6> </p> </div> </code> ` but after doing all this thing my sidebar i.e woo_tabs is not proper you can check the image http://i52.tinypic.com/2gxe90p.jpg here my woo tabs instead of coming side by side, it is coming down, is my code right? | Trim your above code down to.. <code> <?php wp_enqueue_script( "my_script", plugins_url( '/your-script-name.js', __FILE__ ), array( 'jquery' ) ); ?> <?php wp_head(); ?> <?php woo_head(); ?> </code> Place your jQuery into a JS file, then enqueue it with jQuery as a dependancy(as above), this will ensure jQuery is loaded before your script is. Your script also needs to use a no-conflict wrapper , and should be updated to read.. <code> jQuery(document).ready(function($){ $('a#my_id').click(function () { if($("h6:first").is(":hidden")) $("h6").slideDown("slow"); else $("h6").hide(); return false; }); }); </code> Or something to that degree.. NOTE: This is wrong.. <code> <?php wp_enqueue_script("jquery"); ?> <script type="text/javascript" src="<?php bloginfo("template_url"); ?>/functions/js/jquery-1.4.4.js"></script> </code> By doing that you're instructing WordPress to load the included version of jQuery, and then also including your own, so essentially you're loading two versions of jQuery(you only need one, i'd suggest the one WordPress ships with - per above suggested code). Hope that helps.. :) EDIT: jQuery updated inline with request in comments. Accompanying HTML for link to work inline with jQUery. <code> <a id="my_id" href="#showform">My Special Link</a> </code> NOTE: I'm still unclear exactly what this jQuery needs to do for you, so i've simply updated the code posted earlier, i hope that's what you're aiming for... else please please clarify with more details. | need jquery help | wordpress |
I would like to know if it is possible to host a wordpress blog on the subdirectory of a rails application: For instance: I would like to have domain.com/blog instead of having my blog on a subdomain: blog.domain.com . I'm currently using lighttpd, but I can switch to something else if there is a solution. Thanks | You can also set an apache Alias to say /blog is /path/to/wordpress so it's technically not inside your RoR app, you can deploy/make changes to the RoR app all day long then, without the need to worry about overwriting wordpress files. | Host wordpress on a subdirectory of a Rails application | wordpress |

You then have two URLs one of which is the actual physical directory and the other is the one you want to appear to the visitors to your website.

I have come across a function before that displayed the exact SQL code that was used in a loop for example, but can't remember. Can anybody tell me that function? Cheers | Hi @Keith Donegan: If I understand your question correctly I think this is what you are looking for? <code> <?php echo $GLOBALS['wp_query']->request; ?> </code> <code> $wp_query </code> is a global variable that contains the current query run by the loop. If you run the above code anytime while the loop is still active or even right after the loop it should give you the SQL from the loop.

Is there a way to limit the size (dimensions) of the image a user can upload to their profile? It looks like Wordpress does do some kind of limiting as uploading a 1024x768 image the result gets scaled down to 360x270, but where is that configured, either in the UI (which I haven't found) or through code? This is the section of the user profile I'm referring to: | It looks like the author image section of the User Profile editor was from the " Author Image " plugin. I didn't suspect that at first because I didn't know that plugins were allowed to modify that screen, so I thought it was just a build-in Wordpress function and that the plugin just allowed for easy display. As it doesn't look like the plugin has a settings page I ended up just modifying the plugin itself. For those curious, the file to modify is <code> sem-author-image-admin.php </code> and the variable is about 3/4 of the way down, just search for the comment <code> // Set a maximum height and width </code> and you'll find it. (There's no guarantee that this will remain the same in future versions and upgrading the plugin will most likely break this, just an FYI) | Limit author image size | wordpress |
