Okay so i have a code so that upon login it issues a cookie, and when login is successful it re-directs to the proper page but does not register as the user being loged in.

<?php
$login_error = "";
if (isset($_POST['login_username']) && isset($_POST['login_password'])) {
    $login_username = strip_tags(addslashes(trim($_POST['login_username'])));
    $login_password = strip_tags(addslashes(trim($_POST['login_password'])));

if (!empty($login_username) && !empty($login_password)) {
    $checkLogin = $db->fetch($db->query("SELECT id, twmauth FROM users WHERE username = '".$login_username."'AND password = '".md5($login_password)."' AND status = '1'"));

    if ($checkLogin != NULL) {
        setcookie("user_id", $checkLogin['id'], time()+604801, "/", DOMAIN);
        setcookie("twmauth", $checkLogin['twmauth'], time()+604801, "/", DOMAIN);
        gotoURL(HTTP_SERVER_BASE."websites");
    }
    else {
    $login_error = "Invalid login details. Try again.";
    }
}
}
?>

Code dependent if user is loged in:
