If语句不适用于访问级别php mysql

我已经搜索了太多关于我可能做错了什么的信息，但是我没有得到一个if声明来提供我想要的结果。这不是我第一次使用if语句，但这似乎是一个挑战。好的，我想根据用户访问级别隐藏列表项的一部分，但我似乎没有让它按预期工作。我的访问级别为普通用户1级，管理员2级

我到底做错了什么？

我终于找到了解决方案，我丢失了双等号来证明我数据库中的数据是正确的，这是我为

<ul>
    <li><a href="#MyBookings" title="My Bookings">My Items</a></li>
    <li><a href="#MyReviews" title="My Reviews">Submit Item</a></li>
    <?php if($_SESSION['privillages'] = '2'){ ?>
       <li><a href="#Incomings" title="Incomings">Incoming Items  </a> </li>
    <?php }else{?>
    <?php } ?>
    <li><a href="#MySettings" title="Settings">Account Settings</a></li>
</ul>`

public function login( array $data )
    {
        $_SESSION['logged_in'] = false;
        if( !empty( $data ) ){

            // Trim all the incoming data:
            $trimmed_data = array_map('trim', $data);

            // escape variables for security
            $email = mysqli_real_escape_string( $this->_con,  $trimmed_data['email'] );

            if((!$email) || (!$password) ) {

            }
            $password = md5( $password );
