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
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>’; }
You can use the fourth parameter of add_menu_page(), the my_unique_slug, to check if the page exists: if ( empty ( $GLOBALS[‘admin_page_hooks’][‘my_unique_slug’] ) ) add_menu_page( ‘Page Title’, ‘Top Menu Title’, ‘manage_options’, ‘my_unique_slug’, ‘my_magic_function’ ); $GLOBALS[‘admin_page_hooks’] is the list of registered pages.
