    The do_trackbacks() function in WordPress is designed to handle the process of sending trackbacks. Trackbacks are a way to notify legacy blog systems that you’ve linked to them. If you link to a WordPress blog, they’ll be notified automatically using pingbacks, no other action necessary. But for sites that don’t support pingbacks, the do_trackbacks() function is used to send a manual trackback. This is a way of interacting and engaging with other blogs.

    Function Definition:

    do_trackbacks( int|WP_Post $post ): void|false

    Parameters:

    • $post (int|WP_Post, required): This parameter can be either the Post ID or a WP_Post object. It refers to the post for which the trackbacks are to be performed.

    Return Value:

    • void|false: The function returns void on successful execution, which means it does not return any value. However, it returns false if the execution fails for some reason, such as if the specified post doesn't exist or if trackbacks are not enabled for the post.

    Sample Usage:

    To use do_trackbacks() in a WordPress theme or plugin, you need to have a specific post ID or a WP_Post object. Here's a simple example of how it can be used:

    // Assume $post_id is the ID of the post for which you want to do trackbacks
    $post_id = 123; // Example post ID
    
    // Perform trackbacks for the specified post
    do_trackbacks( $post_id );
    
    // Alternatively, if you have a WP_Post object
    $post = get_post( $post_id ); // Retrieve the post object
    if ( $post ) {
        do_trackbacks( $post );
    }
    

    In this example, do_trackbacks is called with either a post ID or a WP_Post object. The function takes care of sending trackbacks to the URLs mentioned in the content of the post. This is part of WordPress's linkback mechanism which allows websites to communicate about links and references.
