      • Example Values: A numeric value representing the bookmark ID.
    3. $context (string, optional):

      • Default Value: 'display'.
      • Other Possible Values: 'edit', 'db', etc., depending on how you want to manipulate or display the data.

    Return Values:

    • Type: string|WP_Error
    • Description: The function returns the value of the specified field if successful. If an error occurs, it returns a WP_Error object.

    Sample Usage:

    Example 1: Retrieve the Name of a Bookmark

    $bookmark_id = 123; // Replace with your bookmark ID
    $bookmark_name = get_bookmark_field('name', $bookmark_id);
    if (!is_wp_error($bookmark_name)) {
        echo 'Bookmark Name: ' . esc_html($bookmark_name);
    } else {
        echo 'Error retrieving bookmark name.';

    Example 2: Retrieve the URL of a Bookmark in Edit Context

    $bookmark_id = 456; // Replace with your bookmark ID
    $bookmark_url = get_bookmark_field('url', $bookmark_id, 'edit');
