I would like to encourage my facebook app users to invite more friends to join the app. Therefore, I will let them freely use my app after they invite more than 50 friends (no matter their friends join the app or not is also ok).

But the problem is: how can I check the number of invitation sent by that users?

Thanks.

there is no built in option in facebook for this.

I'm using the FB request dialog and whenever we send request facebook will return a set of request id's (in case of multiple simultaneous requests) .

And then just have your own table say 'tbl_requests' where you can update the current user_id with the request_id returned by the facebook dialog.. The advantage is that you can then backtrack these request_ids when the invited person accepts his invitation.

the sample code could be,

function invite(){
var receiverUserIds = FB.ui({ 
 method : 'apprequests',
 message: 'just a invite msg'
 title: 'Select your friends to join the app',
},
function(receiverUserIds) {
 if(receiverUserIds){  
  $.ajax({
       type: "POST",
       url: "your_file.php",
       req_ids="+receiverUserIds.request_ids,
  });
 }
}
);                 
}

In your_file.php process your request_ids and store them on db and then whenever you want to count the no of request sent you can just query with the current user_id

        console.log(response);
        for (var i = 0; i < response.to.length; ++i)
