Twentyten has a header.php file which has the style.css hardcoded into it: <link rel=”stylesheet” type=”text/css” media=”all” href=”https://wordpress.stackexchange.com/questions/40174/<?php bloginfo(“stylesheet_url’ ); ?>” /> There is no way to wp_dequeue_style because it is never “loaded” with wp_enqueue_style in the first place. To get that out of the header you’ll need to edit the twentyten theme (bad idea) or … Read more
It’s not true that you have to use wp_localize_script before the wp_head. Since 3.3 you can use wp_enqueue_script in the body of the document (i.e. in a widget or shortcode callback) and the script is loaded in the footer. Here’s a skeleton class I’ve used for adding variables for each instance of a widget to … Read more
I found that there is a filter, manage_posts_columns (and a related manage_pages_columns), that lets you modify the column headers on the “All Posts” admin screen. Using this filter is pretty simple, as the filtering function takes in an associative array with the short name of the column as a key and the heading as the … Read more
For AJAX you need to hook into the wp_ajax_{action} hook Specifically, add_action(‘wp_ajax_my_action’, ‘my_action_callback’); add_action(‘wp_ajax_nopriv_my_action’, ‘my_action_callback’); See http://codex.wordpress.org/AJAX_in_Plugins

We can override the Ajax call to wp_ajax_get_tagcloud() and do a clean hack. <?php /* Plugin Name: Custom Admin Tag Cloud */ add_action( ‘wp_ajax_get-tagcloud’, ‘ajax_tag_cloud_wpse_99497’, 1 ); function ajax_tag_cloud_wpse_99497() { // PASTE ALL THE MODIFIED FUNCTION HERE // http://core.trac.wordpress.org/browser/tags/3.5.1/wp-admin/includes/ajax-actions.php#L639 } Restore your core files to its original state, copy the modified function inside the above … Read more
function disable_editor_for_old_posts_wpse_101106($post) { if (strtotime(‘-2 months’) > strtotime($post->post_date)) { remove_post_type_support(‘post’,’editor’); } } add_action(‘add_meta_boxes_post’, ‘disable_editor_for_old_posts_wpse_101106′); I couldn’t find a great hook for this but add_post_meta_boxes_* is early enough, and it passes the $post object to the callback. Basically the filter checks the post on the post edit screen and removes post type support based on the … Read more
The dynamic wp_ajax_ hooks serve mostly organizational convenience on PHP side. You could choose not to use it, then you would probably have to: hook into admin_init check that DOING_AJAX is true check that request ($_REQUEST[‘action’] and rest of it) is your special kind of request Then either process your request and die() or let … Read more
Try changing your content and saving again. This will trigger the action. save_post is only called if the content has changed. To come in before this is checked, you can use the pre_post_update hook. add_action( ‘pre_post_update’, ‘saving_metabox’ ); function saving_metabox( $post_id ) { die(‘test’); }
