Check if someone Likes a specific Facebook Page

I was wondering if there is a way, using the Graph API, to check if a specific user likes a specific Facebook Page.

I know this can be done post-Authentication, but what about if I don't use Facebook Connect. Can I somehow check this?

 

You can try the FQL query statement.

$likeID = $facebook->api( array( 'method' => 'fql.query', 'query' => "SELECT source_id FROM connection WHERE source_id ='$user[id]' AND target_id = '$pageId'" ) );

if($likeID){
    echo "User has liked the page";
}else{
    echo "User hasn't liked the page yet";
}

Code (markup):

 

if you know the user id then use this api pages.isFan

http://developers.facebook.com/docs/reference/rest/pages.isFan/

 

learning here, but does it violate privacy.

 

Thank you, helpful.

 

can i do the same with "Share"?

leaumer is right ,yes you can use it the fql query ,known the user who like it the facbook page

 

Agreed, FQL.query is the way forward. Just make sure that you cache the result, otherwise you'll spend all day wasting API calls and, no doubt, having some failures.
