[wp-hackers] Modifying wp-comments-post.php to accept new custom fields

[DD32]

rather than modifying core files, you should probably use the  
'preprocess_comment' filter inside wp_new_comment() and check for a $_POST  
variable that you've added

However:
compact() takes a list of variables and compacts them into an array, As  
well as adding to that line, you need to also add the actual variable, eg,  
something similar to:
$comment_author_url   = trim($_POST['url']);
$comment_content      = trim($_POST['comment']);

So i miught use
$d_plugin = trim($_POST['d_plugin']);

compact('comment_post_ID', ...., 'd_plugin');
