# Allow duplicate comment?

 * I need to add the condition “except if duplicate comment_text == ‘no comments’”
   to the duplicate comment validation.
 * I’m a copy-paste dev and I’m not sql-code diver yet. I can see the code below
   is in charge of that, but can’t tell where.
 * Can you help me up? (translating the sql would be a plus and would make you my
   god, hehe)
 *     ```
       $dupe = "SELECT comment_ID FROM $wpdb->comments WHERE comment_post_ID = '$comment_post_ID' AND comment_approved != 'trash' AND ( comment_author = '$comment_author' ";
       	if ( $comment_author_email )
       		$dupe .= "OR comment_author_email = '$comment_author_email' ";
       	$dupe .= ") AND comment_content = '$comment_content' LIMIT 1";
       	if ( $wpdb->get_var($dupe) ) {
       		if ( defined('DOING_AJAX') )
       			die( __('Duplicate comment detected; it looks as though you’ve already said that!') );
   
       		/*wp_die( __('Duplicate comment detected; it looks as though you’ve already said that!') );*/
       	}
       ```

 * Sergio,
 * You can use this code I just wrote as a starting point:
    [http://www.strangerstudios.com/blog/2010/10/duplicate-comment-detected-it-looks-as-though-you%e2%80%99ve-already-said-that/](http://www.strangerstudios.com/blog/2010/10/duplicate-comment-detected-it-looks-as-though-you%e2%80%99ve-already-said-that/)
 * My code at that link works by adding some random text to the end of a new comment
   so it doesn’t look like a dupe. Then that text gets removed from the comment 
   after posting.
 * You can add a conditional to the first function to only add the random code when
   the comment body is “no comment”.
 * e.g.
 *     ```
       if($comment_data['comment_content'] == "no comment")
       {
       //add some random content to comment to keep dupe checker from finding it
       $random = md5(time());
       $comment_data['comment_content'] .= "disabledupes{" . $random . "}disabledupes";	
   
       return $comment_data;
       }
       ```
   
 * You need to use all the code from the link above, but add a conditional like 
   this here. I hope this helps.
