PHP身份验证不起作用

Question

我正在尝试使用我的login.php上的cookie建立对个人资料页面的身份验证。我似乎无法通过login.php来验证用户身份。

这是login.php的代码：

if ($result['Password'] != hashPassword($_POST['Password'],$result['SALT'])) {

echo "<script type='text/javascript'>alert('Failed to Login, Please Try Again')</script>";
echo "<meta http-equiv='refresh' content='0' URL= '/login.php'>";
    exit;
    }

else {
  # A righteous login. First, set the nonce to a value that can be
  # checked in your Account table.
  $nonce = gensym();
  submitDB("UPDATE Customer SET NONCE='" . $nonce . "' WHERE CustomerID=" . $result['CustomerID']);

  # Now set cookies containing credentials that expire in just two
  # hours

  setcookie('CustomerID',$result['CustomerID'],time()+ 60*60*2);
  setcookie('credentials',hash('sha512', $result['CustomerID'] . $nonce),time()+ 60*60*2);

  # Cache name for display on other pages
  setcookie('Name', $result['Name'],time()+ 60*60*2);

  # Refresh this page, which will dispatch me to the right page according to privileges.

  echo "<meta http-equiv='refresh' content='0' URL= '/profile.php'>";

  exit;
  }

任何帮助将不胜感激！提前谢谢
