使用php SDK登录Facebook无效

Question

I'm using facebook's php sdk for a login system on localhost. It was working fine without any problems. But when i try to login now, after clicking the login button it just brings me back to the same page without actually logging me in and changes the url to something like this:

http://localhost/test.php?code=AQA6J5GuQQFCpc9mkOOmuR2...etc

I have double-checked all the code and all the source php sdk files needed. They are all there and haven't been changed from the last time i was able to successfully login. But for some reason it isn't working. Can someone please help me out.

As far as I can see Facebook requires the registration of your web site for the ap, to prevent hackers. Therefore I don't think it can ever work if your running it on localhost, it would have to run on a domain name.
