Description
Add a sub menu page.
NOTE: If you're running into the "You do not have sufficient permissions to access this page." message in a wp_die() screen, then you've hooked too early. The hook you should use is admin_menu.
This function takes a capability which will be used to determine whether or not a page is included in the menu.
The function which is hooked in to handle the output of the page must check that the user has the required capability as well.
This function should normally be hooked in with one of the the admin_menu actions depending on the menu where the sub menu is to appear:
-
The normal, or site, administration menu The user administration menu The administration menu
Usage
<?php add_submenu_page( $parent_slug, $page_title, $menu_title, $capability, $menu_slug, $function ); ?>
Parameters
$parent_slug
() (required) The slug name for the parent menu (or the file name of a standard WordPress admin page). Use NULL or set to 'options.php' if you want to create a page that doesn't appear in any menu (see example below).
Default:

For Settings: add_submenu_page( 'options-general.php', ... ); Also see

$page_title
() (required) The text to be displayed in the title tags of the page when the menu is selected
Default:
$menu_title
() (required) The text to be used for the menu
Default:
$capability
() (required) The required for this menu to be displayed to the user.
Default:
$menu_slug
() (required) The slug name to refer to this menu by (should be unique for this menu). If you want to NOT duplicate the parent menu item, you need to set the name of the $menu_slug exactly the same as the parent slug.
Default:
$function
() (optional) The function to be called to output the content for this page.
Default:
The function must be referenced in one of two ways:
if the function is a member of a class within the plugin it should be referenced as array( $this, 'function_name' ) if the class is instantiated as an object or array( __CLASS__, 'function_name' ) if its called statically
in all other cases, using the function name itself is sufficient
Return values
string
The resulting page's hook_suffix, or false if the user does not have the capability required.
Notes
For $menu_slug please don't use __FILE__ it makes for an ugly URL, and is a minor security nuisance.
Within the rendering function $function you may want to access parameters you used in
add_submenu_page()
, such as the $page_title. Typically, these will work:$parent_slug:
get_admin_page_parent()
$page_title:
get_admin_page_title()
, or simplyglobal $title
$menu_slug:
global $plugin_page
Example
add_action('admin_menu', 'register_my_custom_submenu_page');function register_my_custom_submenu_page() { add_submenu_page( 'tools.php', 'My Custom Submenu Page', 'My Custom Submenu Page', 'manage_options', 'my-custom-submenu-page', 'my_custom_submenu_page_callback' ); }function my_custom_submenu_page_callback() { echo ''; echo 'My Custom Submenu Page
'; echo '';}
To hide your submenu link from a top level menu item to which it belongs you would instead do,
add_action('admin_menu', 'register_my_custom_submenu_page');function register_my_custom_submenu_page() { add_submenu_page( null //or 'options.php' , 'My Custom Submenu Page' , 'My Custom Submenu Page' , 'manage_options' , 'my-custom-submenu-page' , 'my_custom_submenu_page_callback' );}
If you are attempting to add a sub menu page to a menu page created via add_menu_page()
the first sub_menu_page will duplicate your add_menu_page()
.
If you want a sub_menu_page in this scenario, you should first create a duplicate of your add_menu_page() and then add your sub_menu_page() second:
add_menu_page('My Custom Page', 'My Custom Page', 'manage_options', 'my-top-level-slug');add_submenu_page( 'my-top-level-slug', 'My Custom Page', 'My Custom Page', 'manage_options', 'my-top-level-slug');add_submenu_page( 'my-top-level-slug', 'My Custom Submenu Page', 'My Custom Submenu Page', 'manage_options', 'my-secondary-slug');
