I'm pretty sure you cant do what you want (in this context).

Take a look at this page : http://fbrell.com/fb.api/does-like

You'll see you need the user to approve a permission to view the likes.

It's a huge security risk to allow someone to see the 'likes' of a user - even for the current page. Think about it you can easily spoof the current page and pretend to be any page.

BUT...

What I recommend you do is just set a cookie for your own benefit (in javascript) when the user 'Likes' your page. Assuming you're getting a large percentage of your 'Likes' from this page then you can safely correlate the presence of the cookie with a 'Like'.

I've seen some security exceptions doing this, but it seems to work (at least in Chrome).
