The newest and most complete tutorial to the settings API can be found here. I’d suggest to take a look there. I used a pretty similar way myself. Sidenote: You should really mark some answer a solution. “0% acceptance rate” will people hold back from answering your Qs anymore.
You can hook into ‘post_submitbox_misc_actions’ or ‘post_submitbox_start’: add_action( ‘post_submitbox_misc_actions’, ‘wpse_45720_submitdiv_extra’ ); add_action( ‘post_submitbox_start’, ‘wpse_45720_submitdiv_extra’ ); function wpse_45720_submitdiv_extra() { print ‘<pre>’ . current_filter() . ‘</pre>’; }
The nav_menu_items are already sorted by menu_order. When you go into the Appearance -> Menus and arrange the order menu the menu_order of each menu item gets updated. To change the orderby parameter in the query that displays the menu you can use pre_get_posts to alter it. Example: add_action( ‘pre_get_posts’, ‘wpse_sort_nav’ ); function wpse_sort_nav( $query … Read more
This is how I solved it: In functions.php // Custom Dashboard function my_custom_dashboard() { $screen = get_current_screen(); if( $screen->base == ‘dashboard’ ) { include ‘admin/dashboard-panel.php’; } } add_action(‘admin_notices’, ‘my_custom_dashboard’); dashboard-panel.php <!– Hide Old Wrap with CSS –> <style type=”text/css”> div#wpcontent div.wrap { display: none; } div#wpcontent div.my-dashboard { display: block; } </style> <!– New Wrap … Read more
“Admin Stickies” for custom post types: To support sticky custom posts in the backend, you can use the following code snippet in your functions.php file in the current theme directory or in your custom plugin: /** * Set admin stickies for the ‘foodmenu’ custom post type */ add_action( ‘init’, function() { if( function_exists( ‘wpse_cpt_stickies’ ) … Read more
Ignore my comment about meta_query. Not only does it not work with $query->set(), you wouldn’t be able to control the critical “A OR B” requirement of the query. Instead, I believe what you require is possible via a combination of both the pre_get_posts action hook and posts_where filter hook as follows. add_action(‘pre_get_posts’, ‘my_show_appropriate_posts’); function my_show_appropriate_posts($query){ … Read more
This meta box is using the function wp_dropdown_users() to list all users. It has only one filter to change the output: wp_dropdown_users. But this filter offers just the complete markup and users. It’s neither easy nor fast to parse this via regex for user names, check their roles and then give back an new HTML. … Read more
Post list in admin (edit.php) use a normal WP_Query, just like frontend can be changed using pre_get_posts. add_action(‘pre_get_posts’, ‘reorder_my_cpt’); function reorder_my_cpt( $q ) { if ( !is_admin() || !$q->is_main_query() ) { return; } $s = get_current_screen(); // change ‘book’ with your real CPT name if ( $s->base === ‘edit’ && $s->post_type === ‘book’ ) { … Read more
Use get_edit_post_link filter. add_filter(‘get_edit_post_link’, ‘get_edit_post_link_178416’, 99, 3); function get_edit_post_link_178416($link, $post_id, $context) { $scr = get_current_screen(); if ($scr->id == ‘edit-post’ && $context == ‘display’) { return ‘http://google.com’; } else { return $link; } } You can see it’s used here
You’re supposed to enqueue on the wp_enqueue_scripts event. Placing the function in functions.php and immediately running it, will make it run on all pages, including the admin area Here’s an example from the devhub: /** * Proper way to enqueue scripts and styles. */ function wpdocs_theme_name_scripts() { wp_enqueue_style( ‘style-name’, get_stylesheet_uri() ); wp_enqueue_script( ‘script-name’, get_template_directory_uri() . … Read more
