Trouble implementing Facebook page tab competition

I am developing a Facebook page tab that will hold a competition.

So firstly there is the fan gate, I have implemented that easy enough with the Facebook php sdk and the signed request.

When the user gets through the fan gate I.e liked the page. There is a form with entry details.

Now I can only allow someone to enter the competition once.

So what I tried was to get the user id, but depending on the Facebook account I either get back the ID or else I get the user ID =0.

Is there any way for me to get a unique value so I can store that the user has entered the competition without having to allow access.

The user id is given in the signed request only if the user has given permissions to the application.
