Pluggable functions are less elastic than filters/actions. You can have only one pluggable function “active” – so only one plugin can override the core function. And you don’t have much control over which plugin will it be (WP will use the pluggable function that gets defined first). So it won’t be very useful if all … Read more
The context within the screen IS where the boxes should display. Available contexts vary from screen to screen. Post edit screen contexts include ‘normal’, ‘side’, and ‘advanced’. Comments screen contexts include ‘normal’ and ‘side’. Menus meta boxes (accordion sections) all use the ‘side’ context. Global default is ‘advanced’. So it is the place you are … Read more
You just need to send the nonce along with your AJAX data: $.ajax({ type: ‘POST’, url : profile_edit.ajaxurl, data: $(‘#profile_update’).serialize() + ‘&my_nonce=” + profile_edit.nonce + “&action=update_profile_post’, // don’t forget the action name! }); Alternatively, since you’re using jQuery’s serialize() function, you could just add the nonce directly in the form: <?php wp_nonce_field( ‘update_profile_validation’, ‘my_nonce’ ); … Read more
You can use the show_option_all argument: <?php $args = array( ‘show_option_all’ => ‘Categories’ ); wp_dropdown_categories( $args ); ?> Function Reference/wp dropdown categories
I’m not sure this is a problem you really need to solve. Any regular Chrome user knows this is how Chrome (doesn’t) handle RSS. That said, you can provide a custom feed template. see Customizing Your Feeds in Codex.
Add a static variable to the shortcode handler to check if the shortcode has been called already. Sample code add_shortcode( ‘wpse62826’, ‘wpse_62826_shortcode’ ); function wpse_62826_shortcode() { static $done = FALSE; // Nothing to do. if ( $done ) { return; } if ( is_singular() ) { $done = TRUE; } return ‘<b>I run once on … Read more
I don’t think it’s possible to do it with the get_users function. From what the Codex implies, you cannot pass arrays to the role argument. But it should be fairly easy to code your way out of that limitation. Try this: function filter_two_roles($user) { $roles = array(‘academic’,’student’); return in_array($user->roles[0], $roles); } $users = get_users(‘fields=all_with_meta’); // … Read more
You have to set the $single paramter of get_post_meta to false (or don’t set it) to get an array. Here is a sped-up version: if ($attachment_id = get_post_meta($post_id, ‘featured_image’, true)) : elseif ($attachment_id = get_post_meta($post_id, ‘upload_single_image’, true)) : elseif ($attachment_id = get_post_meta($post_id, ‘create_gallery’, false)) : $attachment_id = $attachment_id[0][‘upload_image’]; endif; Note: I did not test this. … Read more
Fist error I see is a syntax error: depth => 0 should be “depth” => 0 Second error is that you are using a category object like a post object. None of these lines will work: There is no post data to setup. Remove this line: setup_postdata($category); A category object has no category_modified property. Maybe … Read more
I would go about this slightly differently. Still using the wp_get_nav_menu_items filter, but first I’ll build an array containing the IDs of all empty terms. Then I’ll compare each of the $items to this for potential exclusion: add_filter( ‘wp_get_nav_menu_items’, ‘wpse177082’, 10, 3 ); function wpse177082 ( $items, $menu, $args ) { global $wpdb; $empty = … Read more
