echo "authmethod = cookies\n";
$cdata = explode("|", $pafiledbcookie);
$ip = $cdata[0];
$user = $cdata[1];
$pass = $cdata[2];
echo "ip = $ip, user = $user, pass = $pass\n";
}
if (!empty($user)) {
echo "user not emtpy\n";
$admin = $pafiledb_sql->query($db, "SELECT * FROM $db[prefix]_admin WHERE admin_username = '$user'", 1);
$adminip = getenv ("REMOTE_ADDR");
$md5ip = md5($adminip);
if ($pass == $admin[admin_password] && $md5ip == $ip) {
$logged = 1;
}
} else {
echo "user empty\n";
$logged = 0;
