Here is a solution I just came up with which doesn’t use jQuery: There is a filter parent_file in wp-admin/menu-header.php which runs right before outputting the menu. The inline comment says: For plugins to move submenu tabs around. It is just a filter on the global variable $parent_file and I am not sure what it … Read more
I made this work iterating through a post types list, and pinpointing the correct $menu key for the post type using a secondary function (instead of manually iterating through the $menu object). Function reference: get_post_types and wp_count_posts. add_action( ‘admin_menu’, ‘pending_posts_bubble_wpse_89028’, 999 ); function pending_posts_bubble_wpse_89028() { global $menu; // Get all post types and remove Attachments … Read more
Here’s an example of the data returned from the wp_get_update_data() function: Array ( [counts] => Array ( [plugins] => 3 [themes] => 2 [wordpress] => 0 [translations] => 0 [total] => 5 ) Displaying the number of updates available in the Admin area => 3 Plugin Updates, 2 Theme Updates ) So the number of … Read more
Use a submenu page as parent slug. The admin menu has just two levels, so the imaginary third level will be hidden. Sample code, tested: add_action( ‘admin_menu’, ‘wpse_73622_register_hidden_page’ ); function wpse_73622_register_hidden_page() { add_submenu_page( ‘options-writing.php’, ‘Hidden!’, ‘Hidden!’, ‘exists’, ‘wpse_73622’, ‘wpse_73622_render_hidden_page’ ); # /wp-admin/admin.php?page=wpse_73622 } function wpse_73622_render_hidden_page() { echo ‘<p>hello world</p>’; }
The ‘View details’ link in the installed plugins list table is only shown for plugins that are hosted in the WordPress.org plugin repository. If you take a look at the source for WP_Plugins_List_Table->single_row(), you’ll see that the details link is only generated if there’s API data present, e.g. the slug is set: // Details link … Read more
No, it is not possible to create third level menu in admin panel. If you look at the definition of add_submenu_page, you need to mention the parent slug name. For eg: add_menu_page ( ‘Test Menu’, ‘Test Menu’, ‘read’, ‘testmainmenu’, ”, ” ); add_submenu_page ( ‘testmainmenu’, ‘Test Menu’, ‘Child1’, ‘read’, ‘child1’, ”); The first parameter of … Read more
add_action(‘admin_menu’, ‘my_remove_sub_menus’); function my_remove_sub_menus() { remove_submenu_page(‘edit.php’, ‘edit-tags.php?taxonomy=category’); remove_submenu_page(‘edit.php’, ‘edit-tags.php?taxonomy=post_tag’); }
There is a dirty (actually dirty as hell) way to attach a ordinary WordPress page as archive page from a custom post type settings page. You need to unregister post type first, and create again. If you don’t use custom arguments or if you brave enough try this code. Add this code fragment end of … Read more
I ran into that issue too, and it turns out that it was because there actually was an error that wasn’t displaying. Once I fixed that underlying error, the top margin problem went away. This is in wp-admin/admin-header.php: // Print a CSS class to make PHP errors visible. if ( error_get_last() && WP_DEBUG && WP_DEBUG_DISPLAY … Read more
Hi @JM at Work: Yes, it is unfortunately that the submenu page is added for every menu page. It would be nice if there were an option but alas, there currently is not. To remove the submenu page option in WordPress 3.1 or great use remove_submenu_page() with code like this in your theme’s functions.php file, … Read more
