I made a few Facebook FBML Canvas pages (Facebook considers these to be Applications) for a company, and they requested that users who "Like" the page would be redirected to another page, or the page will display different content with AJAX.
I went through the Facebook Developers Documentation, but I can't find a clue on how to do it.
I'm sure someone has done it before, any suggestions?
I found this on the Facebook forum I think it might help you out!
How can i redirect when someone like/share?
I haven't tried it myself though!
Good luck!
You can use either the JS or PHP sdk to check if a user liked a page. See examples below...
Uses JS sdk to check if a user liked a page (can be any page, just set the page id). This can be used in a standalone app or from within a page tab. - http://unbound-media.com/facebook/how-to-tell-if-a-facebook-user-likes-your-facebook-application/
Uses PHP sdk to check if a user liked the page from a tabbed app (can only check if user liked the current page they're on). This method can also be converted to JS. - How to check if a user likes my Facebook Page or URL using Facebook's API
If you are dealing with facebook app tab page, the following code helps you to find isfan status
$signed = parse_signed_request($_REQUEST['signed_request'], 'YOUR-APP-SECRET');
if ($signed['page']['liked'] == 1) {
$fan = true;
} else {
$fan = false;
}
