    @sem101, when receiving, “Undefined Index,” notices from PHP, usually a key is not set. You check if it’s set with:

    isset()

    Example:

    MRP_save_relationships( $post_id, isset( $_POST['MRP_related_posts'] ) );

    The developer may wish to add a ternary operator as well. Good luck.
