如何让所有朋友都喜欢在Facebook上？

Question

I would like to get all likes of a user's friend on Facebook. So far I know how to take all likes of an authenticated user by FQL query:

SELECT object_id, object_id_cursor,object_type, post_id, post_id_cursor, user_id FROM like WHERE user_id =me()

However I'd like to have similar information about ALL user's friends.
So the question is how to get all likes from user's friends. Does anybody can give me a hint on it?

Answer 1

I don't think it's possible to get all with FQL, you need to get a list of the user's friends id's, and then run the query against each friend..

$friends = array(); //an array of user ids
foreach($friends as $value){
    //Create query
    $fql = "SELECT object_id, object_id_cursor,object_type, post_id, post_id_cursor, user_id FROM like WHERE user_id = $value";
}

However I don't think you want to go with FQL , you can do things in an easier manner using the graph API with batched requests (you'll end up with hundreds of API calls if you do this in FQL, and will probably end up with your APP blocked by facebook)

Answer 2

So far you can take only URLs that your friends have liked. Here is the FQL request to do it:

SELECT url FROM url_like WHERE user_id={friendId}

All friend ids you can get by fql query or by API call.
