It all depends on whether the client's browser decides to give that information to your script. The variable $_SERVER['HTTP_REFERER'], if set, refers to the page that led the user there. Unfortunately, browsers aren't obligated to set it in any way, so you can never be sure.
Actually, a more fail-proof method to do that (without Javascript) would be to use an <input type="hidden" name="url" value="CURRENT_URL" /> or something similar.

I like to think about anything that can happen.

The user can change it I think, right?
Yes, I managed to do it in another way, but er, thanks everyone!

Although hard coding it in would work better.Quote from: ephan on September 11, 2011, 04:50:52 pmYes, I managed to do it in another way, but er, thanks everyone!Np, glad to be able to give you some options. How did you actually go about doing it might I ask?
