using $http_referer in $self 4 includes

[Anon]

hi, i'm using fopen to include a referring document so somone can email it as an attachment. trouble is, <FORM action="<?php echo $PHP_SELF; ?>"

it ends up emailing the little emailer form as the attachment. cute huh? any ideas on how to set
$referring_doc = getenv("HTTP_REFERER");
as something that won't change when the script goes to processing?

code at: http://www.uac.pdx.edu/forms/shareit.phps

thank you!

Hi,

I've not looked at your code, but from a previous project, I think I may have a solution. This is what you do:

when someone clicks on "email this page", you are generating that form using PHP right? So, using the PHP, add a hidden form element which stores the referer:

<input type=hidden name="referer_url" value="<?php echo $HTTP_REFERER; ?>">

That way, when the form gets submitted back to $PHP_SELF, you can email the URL: $referer_url (which is the form value) instead of using $HTTP_REFERER (which will point to the PHP program itself).

hope this works!
