Answers ( 1 )


    The remove_meta_box() function in WordPress is used to remove meta boxes from one or more screens in the WordPress admin area. Meta boxes are the draggable boxes visible on post edit screens, which contain various options or information.

    Here's a detailed explanation of the function and its parameters:


    • Purpose: remove_meta_box() is designed to remove a specified meta box from certain screens or contexts within the WordPress admin area. This is useful for customizing the admin interface, especially if certain meta boxes are not needed or if you want to simplify the editing environment.


    1. $id (string, required):

      • Description: This is the ID of the meta box you want to remove. The ID is a unique identifier used in the 'id' attribute for the meta box in HTML.
      • Example: If you want to remove the meta box for custom fields, you would use the ID 'postcustom'.
    2. $screen (string|array|WP_Screen, required):

      • Description: This parameter specifies the screen or screens from which you want to remove the meta box. It can be a single screen ID, a WP_Screen object, or an array of screen IDs.
      • Example: To remove a meta box from the post editing screen, you could use 'post'. If you want to remove it from multiple screens, you can pass an array like ['post', 'page'].
    3. $context (string, required):

      • Description: This refers to the area within the screen where the meta box is displayed. Contexts can be 'normal', 'side', or 'advanced' for post edit screens. For comment screens, the contexts are 'normal' and 'side'. For menus, it's usually 'side'.
      • Example: If a meta box appears on the side of the post edit screen, you would use 'side' as the context.

    Sample Usage:

    Here's an example of how to use remove_meta_box() in a WordPress theme or plugin:

    function my_remove_meta_boxes() {
        remove_meta_box('postcustom', 'post', 'normal'); // Remove Custom Fields meta box from posts
        remove_meta_box('tagsdiv-post_tag', 'post', 'side'); // Remove Tags meta box from the side of posts
        remove_meta_box('dashboard_incoming_links', 'dashboard', 'normal'); // Remove Incoming Links meta box from the dashboard
    add_action('admin_menu', 'my_remove_meta_boxes');

    In this example:

    • The first line removes the 'Custom Fields' meta box from the normal context of the post editing screen.
    • The second line removes the 'Tags' meta box from the side of the post editing screen.
    • The third line removes the 'Incoming Links' meta box from the normal context of the dashboard screen.

    By using remove_meta_box(), you can tailor the WordPress admin interface to better fit your needs or the needs of your clients, removing unnecessary or unwanted elements for a cleaner and more focused editing experience.
