Capability parameter of add_submenu_page() function can only take a single capability, so if you are using the built in roles you can select a capability fro the long list that both administrators and editors have any of these (use any of these freely): moderate_comments manage_categories manage_links unfiltered_html edit_others_posts edit_pages edit_others_pages edit_published_pages publish_pages delete_pages delete_others_pages delete_published_pages … Read more
The WordPress functions changed since the answers here in 2014. As of today (Version 4.6.1) this code will create a main menu named “My Menu” , main item and sub item. To run code just paste and saves in your functions.php file in your child theme. $menu_id = wp_create_nav_menu(‘My Menu’); $parent_item = wp_update_nav_menu_item($menu_id, 0, array( … Read more
If you connect your functions with proper hooks your submenu page will be displayed after your post type and taxonomy. Take a look at my example: /** * Register event post type * * Function is used by init hook */ function wpse_288373_register_event_post_type() { $labels = array( ‘name’ => __( ‘Events’ ), ‘singular_name’ => __( … Read more
It would go like this (note the absence of the function parameter – and also the capability instead of a role). add_action( ‘admin_menu’, ‘wpse_74421_menu_admin’ ); function wpse_74421_menu_admin() { add_submenu_page( ‘edit.php?post_type=events’, ‘Add Gallery’, ‘Add Gallery’, ‘delete_plugins’, ‘admin.php?page=nggallery-add-gallery’ ); }
You’d have to manipulate the global $submenu and modify the link in it. Or use jQuery. The following example adds a submenu in the Dashboard menu and changes the destination link just after. The submenu page will dump the contents of the global var. add_action( ‘admin_menu’, function() { add_submenu_page( ‘index.php’, ‘Sandbox Options’, ‘Options’, ‘administrator’, ‘sandbox_options’, … Read more
Make sure that your add_action hook is set to admin_menu. Here’s a sample code: add_action(‘admin_menu’, ‘wpse149688’); function wpse149688(){ add_menu_page( ‘Wholesale Pricing’, ‘Wholesale’, ‘manage_options’, ‘woo-wholesale’, ‘woo_wholesale_page_call’); add_submenu_page( ‘woo-wholesale’, ‘Registrations’, ‘Registrations’, ‘manage_options’, ‘woo-wholesale-registrations’, ‘wwpr_page_call’ ); } Also check whether user you’ve logged in as has the ability to view this menu. As this menu is set using … Read more
I renamed the “SmartPost E-mail” plugin folder so it loads after the “SmartPost” plugin – I think. I’m pretty sure this “weird” behavior has to do with the order in which plugins are loaded. If a plugin is loaded before its “parent” plugin, then the weird behavior mentioned above will probably happen.
For the custom link into the admin menu, you need to pick up a top-level menu item by its slug and register the function using the admin_menu action hook. Here is the list of Main Admin Menu slugs. index.php => Dashboard edit.php => Posts upload.php => Media link-manager.php => Links edit.php?post_type=page => Pages edit-comments.php => … Read more
This is an old post but can’t you just use wordpress $menu and/or $submenu globals like Oleg suggested in number 2. When in doubt copy WordPress: wordpress/wp-admin/menu.php For example to add link this seems like it would work: function add_external_link_admin_submenu() { global $submenu; $permalink = admin_url( ‘edit-tags.php’ ).’?taxonomy=category’; $submenu[‘options-general.php’][] = array( ‘Manage’, ‘manage_options’, $permalink ); … Read more
Set the parent_slug property to null, example; add_submenu_page( null // -> Set to null – will hide menu link , ‘Page Title’ // -> Page Title , ‘Menu Title’ // -> Title that would otherwise appear in the menu , ‘administrator’ // -> Capability level , ‘menu_handle’ // -> Still accessible via admin.php?page=menu_handle , ‘page_callback’ … Read more
