Facebook: Determine if User is Fan (likes page)

Question

Is there a way to determine if the current user is a fan (now: likes the page) using facebook connect?

I know this is possible in the REST api, but I would like to be able to just use connect instead.

Answer 1

First you need to log the user in with Facebook connect and the Javascript SDK.

Then in Javascript you can use FB.api to call the Graph API.

FB.api('/me/likes');

This requires the user_likes permission to be granted when they login.

Answer 2

I'd rather use FQL: SELECT page_id FROM page_fan WHERE uid=me() and page_id=114342017879

If the query returns an empty array, then your user is not fan. If it returns the page id in an array, then he's fan:

[
    {
        "page_id": "114342017879"
    }
]
