Question

So I have an iFrame app on a fan page, which includes the comments plugin. Is there a way I/any admin can receive a notification or email every time someone adds a comment?

Answer 1

You can subscribe to comment.create event and send the notification to admin in any way you prefer, once comment is created. Facebook itself doesn’t provide such functionality.

This may looks like this (I assume Facebook JavaScript SDK is already loaded on page before doing this, read about it in documentation on Loading, anyway if you’re using Social Comments Plugin it should be loaded already):

<script type="text/javascript">
  FB.subscribe('comment.create', function(response){
    // Here you need to do a call to some service/script/application
    // to notify your administrator about new comment.
    // I'll use jQuery ajax to call server-side script to illustrate the flow 
    $.post('//hostnamne/path/to/script', {
      "action": "comment created",
      "url_of_page_comment_leaved_on": response.href,
      "id_of_comment_object": response.commentID
    });
  });
</script>

In your script located at http(s?)://hostnamne/path/to/script you can send a notification to admin, how to do it may vary on way you want it for example if you want to send an email you can use something like this php sample (aging this is just a flow sample, not real code you should use):

 <?
   $admin_email = 'root@localhost';

   $commentID = $_REQUEST['id_of_comment_object'];
   $page_href = $_REQUEST['url_of_page_comment_leaved_on'];
   $message = "comment #{$commentID} was leaved on page {$page_href}";

   mail($admin_email, "You have a new comment", $message);
 ?>

If you need to track the deletion of comments too you can use comment.remove event with similar flow…
