Question

I have an application on facebook and i have the facebook comment box on it. If someone makes a comment using the comment box, is there a way to notify person that a post has been made on their app

I have the following code

<script src="https://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<fb:comments xid="test" canpost="true" candelete="false" href="<%= link %>"  num_posts="10" width="500" send_notification_uid="<%= fbUserId %>" notify="true" publish_feed="true"></fb:comments>

The href – link is a dynamic link depending on where the post was made. The send_notification_uid – user_Id is also dynamic and it retrieves the user id of the person that owns the page.

Any help would be great. It all works apart from the send notification

Answer 1

I believe using the javascript SDK you can subscribe to the comment.create event. Then provided you have the necessary permissions for the uid in question, you could then send them a notification I believe. I haven’t tested this but you need to look at the FB.event.subscribe code

https://developers.facebook.com/docs/reference/javascript/FB.Event.subscribe/

There’s some more information on a post here

Further to this you can test things out on the js skd tool

https://developers.facebook.com/tools/console/

and some sample code

<h1>Defaults</h1>
<fb:comments href="http://www.fbrell.com/"></fb:comments>

<script>
FB.Event.subscribe('comments.add', function(resp) {
console.log('Comment was added' + resp);
});
</script>
