[RESOLVED] why isn't this working...

[listenmirndt]

i am trying to set a cookie based on the first entry into my website (HTTP_REFERER)

but after visting the next page, it shows the most recent HTTP_REFERRER (my website)

if (empty($HTTP_COOKIE_VARS[ref]))

{
setcookie("ref", $_SERVER[HTTP_REFERER]);
}

echo $HTTP_COOKIE_VARS[ref];

so i thought this would only set the cookie ref IF it was empty, but it seems to set it no matter what...

Couple of problems:

1. The $HTTP_COOKIE_VARS variable has been deprecated for some time now; you should be using $_COOKIE instead.

2. Strings in array indexes should be quoted (just as they would be elsewhere).

EDIT: Also note that unless you specify otherwise, cookies will be set for the current "subdirectory" in the URL, e.g. a cookie set in mysite.com/foo/bar.php won't be visible in mysite.com/bar/foo.php unless you specify the path as '/' (meaning the entire domain).

Speaking of the domain, also note that mysite.com and www.mysite.com are not the same as far as cookies are concnered (since the former has no subdomain while the latter does).

thanks! it was a path issue
