PHP Cookies not being set in WAMP

Question

I have two scripts, one for processing a login and one for registering a login, they both create a sessiod id and insert it into both a cookie and a database. The DB insert works just fine, however, the cookies are not set:

login:

//...Stuff...
$sql = "SELECT * FROM dm_users WHERE username = '$username' LIMIT 1";
    $res = mysql_query($sql);
    if(mysql_num_rows($res) == 0) {
        header("Location: denied.php?u");
        die();
    }
    while($r = mysql_fetch_assoc($res)){
        $brought = $r['password'];
    }
    if (PassHash::check_password($brought, $password)) {  
        if($remember == 1) {
            $time = time() + (10 * 365 * 24 * 60 * 60);
        } else {
            $time = 0;
        }
        $val = uniqid() . time();
        setcookie("dmsesid",$val,$time);
        $sql = "INSERT INTO dm_sessions (username,sesid,`timestamp`) VALUES ('$username','$val',now())";
        $r = mysql_query($sql);
        $sql2 = "UPDATE dm_users set lastlogin = NOW() WHERE username = '$username'";
        $r2 = mysql_query($sql2);
        header('Location: ../characters.php');
    } else {  
        //...More stuff...

Register process works in much the same way, but only with the $time = 0; option.

Any help would be greatly appreciated!

I think you have to set the path for the cookie

setcookie("dmsesid",$val,$time, '/');

From PHP manual:

The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain . If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain . The default value is the current directory that the cookie is being set in.
