Function and usage of attachment_submit_meta_box() in wordpress


Answers ( 1 )


    The attachment_submit_meta_box() function in WordPress is a specific function used to display submit form fields for an attachment. Here's a detailed explanation and sample usage:


    • Name: attachment_submit_meta_box()
    • Purpose: This function is used to display the submit form fields for an attachment in WordPress. It's typically used in the admin area where you manage media files.


    • $post (WP_Post): This is the only parameter required by the function. It's an object representing the current post or media attachment. The $post object contains all the information about the post or attachment, like its ID, title, content, etc.


    To use this function, you should have a WP_Post object that represents the attachment you're working with. This function is usually not called directly by theme or plugin developers. Instead, it's used internally by WordPress in the media attachment editing screen.

    Here's a basic example of how the function might be used, though it's more illustrative than practical:

    global $post;
    $post = get_post( $attachment_id ); // Assuming $attachment_id is the ID of your attachment
    if ( $post instanceof WP_Post ) {
        attachment_submit_meta_box( $post );

    In this example:

    • We're getting a post object for a specific attachment using get_post().
    • We check if $post is an instance of WP_Post to ensure it's a valid post object.
    • Then, we call attachment_submit_meta_box() with $post as the argument.

    Context and Practical Use

    • Admin Area: This function is mainly relevant in the WordPress admin area, particularly on the attachment editing screen.
    • Custom Development: In most cases, theme or plugin developers do not need to interact directly with this function. It's part of the WordPress core and handles the display of attachment submit boxes automatically.


    • WordPress Core Function: Since attachment_submit_meta_box() is a part of the WordPress core, it's subject to change in future WordPress updates. Always refer to the WordPress Codex or Developer Resources for the most current information.
