im trying to do an app that doesn’t require to redirect for authorize.
What i wanted to do is an app that detects if it likes a page it shows some content,
of doesn’t like, it shows another kind of content.
How can i do ?
Thanks and have a nice day!
You can do this using the PHP SDK (or similar). All you have to do is put the app on a Fan Page and decode the
signed_requestparameter and see if the user has liked the page (liked =>1.You can decode the signed_request by calling:
$facebook->getSignedRequest();and thenvar_dumpit to see the data it returns.
