# Problems with wp_insert_comment

 * I’m using wordpress to implement a very simple blogging system on my already 
   existing website. I’ve now come across a problem with inserting comments.
 * I’m using wp_insert_comment to add a new comment for a specific post like below
   which works just fine.
 *     ```
       $comment_post_ID = (int) $_POST['comment_post_ID'];
       $comment_author = ( isset($_POST['author']) ) ? trim(strip_tags($_POST['author'])) : null;
       $comment_author_email = ( isset($_POST['email']) ) ? trim($_POST['email']) : null;
       $comment_author_url = ( isset($_POST['url']) )     ? trim($_POST['url']) : null;
       $comment_content = ( isset($_POST['comment']) ) ? trim($_POST['comment']) : null;
       $comment_type = 'comment';
       $comment_parent = isset($_POST['comment_parent']) ? absint($_POST['comment_parent']) : 0;
   
       $commentdata = compact('comment_post_ID', 'comment_author', 'comment_author_email', 'comment_author_url', 'comment_content', 'comment_type', 'comment_parent', 'user_ID');
   
       $comment_id = wp_insert_comment( $commentdata );
       ```
   
 * The problem appears when I try to check for duplicate comments. I do this by 
   getting all of the comments for the post and then comparing the new comment with
   the old ones. So basically I add the following before the w_insert_comment function.
 *     ```
       $comments = get_comments("post_id=$comment_post_ID");
   
       code here to compare these comments to the new one.
       ```
   
 * I’ve narrowed it down to the get_comments function. If I don’t include it everything
   works fine. If I do include it the insertion of the comment doesn’t happen. Any
   ideas why?
 * Any help would be much appreciated.
