Password_verify bcrypt not working

Question

谢谢你在这个问题上的帮助。我试图将密码与php password_verify进行比较，但它不起作用。我的代码有问题吗?(我得到第二条消息"无效的用户或密码")干杯!

function login_aut($uname, $pass){
     include('_con.php');
     include('password.php');
    $stmt = $conex->prepare("SELECT id, pass FROM tb_users WHERE uname =?");
    /* bind parameters for markers */
    $stmt->bind_param("s", $uname);
    /* execute query */
    $stmt->execute();
    /* get num of rows */
    $stmt->store_result();
    $numrows = $stmt->num_rows;
    if(($numrows) == ""){echo 'INVALID USER ';die();}
    $stmt->bind_result($u_id,$upass);
    $stmt->fetch();
    /* close statement */
    $stmt->close();

if (!password_verify($pass,$upass)) { echo 'INVALID USER OR PASSWORD'; die(); }

谢谢大家的帮助!问题出在DB列的长度上，它不够长，不能进行哈希。谢谢你！
