change admin display name for all existing comments

[mrjWells]

I think this is actually a wordpress question, but hours of searching the web has not helped me find an answer. So, thought I would ask my favorite experts!

Here’s my question: Is there a way to change the admin display name for existing comments?

I know I can edit each comment by hand, but there are thousands of them.
I also know that I can change the display name for future comments in the “edit users” section.

But my goal is to change the display name on all existing admin comments. Can this be done?

Hi,
Please insert this code at functions.php :-

add_filter('get_comment_author', 'wpse31694_comment_author_display_name');
function wpse31694_comment_author_display_name($author) {
    global $comment;
    if (!empty($comment->user_id)){
        $user=get_userdata($comment->user_id);
        $author=$user->display_name;
         $author = ( $author == 'admin' ) ? 'myNewName' :  $author;
    }

    return $author;
}

Thanks 🙂
With Best Regards

Wow, looks good Mohammad.

So, just to be sure I do this correctly, do I put the name I want to display where it says ‘myNewName’?

And do I need to put the old display name or my username anywhere in the code?

The current display name is ‘Jonathan – Advanced Life Skills’ and I just want it to say ‘Jonathan’, my username is ‘jWells’

Hi,
Yes, you can replace myNewName with Jonathan to make change as you desire.
Thanks
