In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track
- by Tony
I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize:
<script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script>
FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") });
FB.ensureInit(function () {
FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback);
});
However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error -
FB.ApiClient is undefined
I am also using the FBML fan tag to display the "become a fan" button:
<fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan>
And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan.
The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.
