How do you pass HTTP_REFERER through a web form?

[edrandall]

I'm a php newbie, so forgive my ignorance!

I'm designing a site with an EMAIL THIS PAGE option - i.e., you click EMAIL THIS PAGE, fill out a quick form, and the form processor sends out an email with the URL of the page just prior to the form.

I'm almost there, but I can't figure out exactly how to use "HTTP_REFERER" to 1) get the URL of the page linking to the form, and 2) pass the URL through the form to the form processing script so it can be e-mailed.

Here's a little code I thought might do the trick: (no such luck)

(FROM THE FORM PAGE)

<input type="hidden" name="url" value="$_SERVER['HTTP_REFERER']">

(IN THE FORM PROCESSING SCRIPT)

$url = $_POST['url']

Anyone know what I'm missing??

Thanks in advance,
Ed

Try changing it to this

<input type="hidden" name="url" value="<?php print $_SERVER['HTTP_REFERER'];?>">.
