Display commenter’s registration date on comments?
In your wp_list_comments callback function, you can call get_userdata to get any additional comment author data: $userdata = get_userdata( $comment->user_id ); echo ‘Registered: ‘ . $userdata->user_registered; // format the date // Sunday January 13th 2013 echo ‘Registered: ‘ . date( ‘l F jS Y’, strtotime( $userdata->user_registered ) );
