Problemer med 'log in application'

Hej Computerworld,

Jeg sidder med  et problem, som jeg efter et tidsrum ikke endnu har kunne løse:

Jeg her lavet en login-applikation, men hver gang logger ind får jeg "invalid user" (selvom brugeren er eksisternede in min DB)

Koden er herunder

<?php


session_start();



require_once "Auth.php";
require_once "Util.php";





$auth = new Auth();
$db_handle = new DBController();
$util = new Util();

require_once "authCookieSessionValidate.php";

if ($isLoggedIn) {
    $util->redirect("dashboard.php");
}

if (! empty($_POST["login"])) {
    $isAuthenticated = false;
   
    $username = $_POST["user"];
    $password = $_POST["pass"];
   
    $user = $auth->getMemberByUsername($username);
    if (password_verify($password, $user[0]["pass"])) {
        $isAuthenticated = true;
    }
   
    if ($isAuthenticated) {
        $_SESSION["user"] = $user[0]["user"];
       
        // Set Auth Cookies if 'Remember Me' checked
        if (! empty($_POST["remember"])) {
            setcookie("member_login", $username, $cookie_expiration_time);
           
            $random_password = $util->getToken(16);
            setcookie("random_password", $random_password, $cookie_expiration_time);
           
            $random_selector = $util->getToken(32);
            setcookie("random_selector", $random_selector, $cookie_expiration_time);
           
            $random_password_hash = password_hash($random_password, PASSWORD_DEFAULT);
            $random_selector_hash = password_hash($random_selector, PASSWORD_DEFAULT);
           
            $expiry_date = date("Y-m-d H:i:s", $cookie_expiration_time);
           
            // mark existing token as expired
            $userToken = $auth->getTokenByUsername($username, 0);
            if (! empty($userToken[0]["id"])) {
                $auth->markAsExpired($userToken[0]["id"]);
            }
            // Insert new token
            $auth->insertToken($username, $random_password_hash, $random_selector_hash, $expiry_date);
        } else {
            $util->clearAuthCookie();
        }
        $util->redirect("dashboard.php");
    } else {
        $message = "Invalid Login";
    }
}
?>
