Question

So this is what I’m doing- I am using facebook login for my site using the php-sdk. I have given the redirect URI to a function that checks if the user exists in my database, if not create the user, then redirect to my home page.

redirect uri is http://somedomain.com/login/check_fb_login
check_fb_login will check if user exists in db, if not create

However, my check_fb_login is not getting the value of the userID.

 $facebook->getUser() is getting 0

Why is this so? getUser should return a value because the user has already been authenticated by facebook right?

Answer 1

Check you are initializing $this->facebook object (by printing appId) or not.
