PHP Question. How to grab current URL and send in an email

[spenland]

I'm sure this will be a piece of cake for you guys. I currently have a form that my company uses for several different promotions that users arrive at through a variety of sources. Each one of these sources have their own referrer i.e Adwords, email ad, etc.

What I would like to do is have a function that will capture the web address currently displayed on the nav bar i.e http://www.mysite.com/web_form.php?referrer=Google

and simply place that address in the email.

How would I do this?

anyone?

Try $_SERVER['PHP_SELF']. It should return the current url. Here is a list of some other predefined variables that php has.

thanks jdiben, I actually found that the PHP_REFERER does exactly what I need, but thanks for pointing me in the right direction!
