I'm writing a website in php that is supported solely by ads, so I'm trying to write a script that check for a cookie that an ad sets... basically the ad link is: http://www.dpbolvw.net/click-1614732-10380895 and I want to check to see if it sets the cookie after they enter thier email address to make shure they used the ad.

<?

if($_COOKIE['tplset_id']!="" and $_COOKIE['campaign_enc']!="" and $_COOKIE['permsid']!="") {
echo "COOKIES NOT DETECTED";
} else {
echo "COOKIES DETECTED";
}

?>

Is that what you wanted?
