Answers ( 1 )


    The add_media_page() function in WordPress is designed to add a submenu page to the Media main menu. It's a useful function for developers who want to extend the WordPress admin interface, especially in the context of media-related features. Here's a detailed explanation of the function and its parameters:


    • Purpose: Adds a submenu page to the Media main menu in the WordPress admin area.


    • This function allows the addition of a new page under the Media menu in WordPress.
    • It checks for user capabilities to ensure that only users with the required permissions can access this submenu page.
    • The function that outputs the content of the new page should also verify that the user has the required capability.


    1. $page_title (string, required):

      • This is the title of the page, which appears in the title tags of the webpage when the menu is selected.
      • Example: 'My Custom Media Page'
    2. $menu_title (string, required):

      • The text that appears in the Media menu for this submenu.
      • Example: 'Custom Media'
    3. $capability (string, required):

      • Defines the required capability a user must have to see this menu item.
      • Example: 'manage_options', 'edit_posts'
    4. $menu_slug (string, required):

      • A unique identifier for this menu, used in URLs and internally by WordPress.
      • Example: 'custom-media-menu'
    5. $callback (callable, optional):

      • The function that will output the content for this submenu page.
      • Default is an empty string, which means no output function is specified.
      • Example: 'my_custom_media_page_callback'
    6. $position (int, optional):

      • Specifies the position in the menu order where this item should appear.
      • Default is null, which lets WordPress choose the position.
      • Example: 5

    Return Value:

    • Type: string|false
    • Description: Returns the hook_suffix for the newly added page which can be used to reference the page later. Returns false if the user does not have the required capability.

    Sample Usage:

    Here's an example of how you might use add_media_page in a WordPress plugin or theme's functions.php file:

    function my_custom_media_page_callback() {
        echo '<div class="wrap"><h1>Custom Media Page</h1>';
        // Your custom page content goes here.
        echo '</div>';
    function register_my_custom_media_page() {
            'My Custom Media Page', // $page_title
            'Custom Media',         // $menu_title
            'manage_options',       // $capability
            'custom-media-menu',    // $menu_slug
            'my_custom_media_page_callback' // $callback
    add_action('admin_menu', 'register_my_custom_media_page');

    In this example, a new submenu item titled "Custom Media" is added under the Media menu. It's visible only to users with the 'manage_options' capability. The my_custom_media_page_callback function is responsible for rendering the content of this new page.
