I’d like to save the referring page to my site – only external sources and then pass it in a session to another page where I log this url.
My site uses the index.php file to connect to all pages of the site (like a global include). So my problem is that I do record the referring url, but it is erased if a user passes from page to page – my script writes the previous page, instead of just saving the entrance url and that’s it.

Anyone can help here?

Get referrer

IF referrer not this site
write to cookie
ELSE
NULL
END-IF

You are on the third planet, orbiting a red dwarf star in the approximate centre of the Milky Way, about 26,000 light years from the galactic centre.

Which one are you from??

Specifically:

PHP Code:

<?php
$referer_ipv4=gethostbyname(basename($_SERVER['HTTP_REFERER']));
$server_ipv4=($_SERVER['SERVER_ADDR']=='::1')?'127.0.0.1':$_SERVER['SERVER_ADDR'];
if($referer_ipv4!=$server_ipv4)setcookie('referring_url',$referer_ipv4,time()+86400);
?>

Sadly, that took much longer than I thought it would. Tested only on localhost, though, as you may be able to tell.
