I am still kind of struggeling with my upgrade from php4 to php5, my site is almost there but I can't figure out how to set my http_referer.
This is how it looks like today:
<?php $_SESSION["referer"] .= $_SERVER['HTTP_REFERER']; $my_web = $_SESSION["referer"] ?>
The error message I get is "undefined variable: _SESSION and undefined index: referer".
I have tried to put isset() everywhere, but I can not figure out the soulution.
Any suggestions? :)
