Accessing the Facebook signed_request parameter in iframe tab page
i was wondering how to access the Facebook signed_request parameter inside an iframe tab?
$_REQUEST['signed_request']
$_POST['signed_request']
Do I always ge开发者_如何学运维t the signed_request? Or do I need to authorize the user first?
Thanks,
Ohh the Facebook PHP SDK has a method for that (using $_REQUEST): $facebook->getSignedRequest()
