I found this code and would like to modify it as follows: if someone changes the display_name, the name in the comments should also change. I was able to achieve this with the following code in the comments:
$usermeta = get_userdata($comment->user_id); <?php echo $usermeta->display_name?>
However, I don't know how to change the code below to show display_name here as well.
if( $comment->comment_parent ) comment_author( $comment->comment_parent );
I appreciate any help.
