Passing cookie value to include files

[Anon]

I have a menu it's an include file I have a link that looks like this

<A HREF="file.php?user_id=<? echo $user_id ?>">Link</A>

This should echo the cookie value right is there something wrong or a different way to call the cookie value

Heres cookie
<?
if (!isset($user_id)) {
$token = MD5(uniqid(rand()));
setcookie("user_id",$token,time()+86400,"/","zonysystems.com");
}
?>

TIA

You need to pull the cookie out of $HTTP_COOKIE_VARS

so

$user_id = $HTTP_COOKIE_VARS["user_id"]; before you create the url link
