的login.php

Question

我正在使用php和mysql创建一个登录页面，但在输入电子邮件和密码并提交输入后，浏览器显示一个空白页面而不进入个人资料页面。

如何修复此错误???

的login.php

    <?php
    $message = ""; 
    if(isset($_POST['email'])!="")
    {
    require_once('include/connect.php');
    $email = $_POST['email'];
    $pass = $_POST['pass'];

    $email = strip_tags($email);
    $pass = strip_tags($pass);
    $email = mysql_real_escape_string($email);
    $pass = mysql_real_escape_string($pass);
    //$pass = md5($pass);
    $firstname="";
    $email="";
    $sql=mysql_query( "SELECT user_id FROM user WHERE email_address='$email'AND password='$pass'LIMIT 1") or die("error in user table");
    $login_check = mysql_num_rows($sql);

      if($login_check > 0)
      {
          while($row = mysql_fetch_array($sql))
          {
              $id = $row['user_id'];
              $_SESSION['user_id']= $id;
              var_dump($id);
              $firstname = $row['first_name'];
              $_SESSION['first_name']= $firstname;
              var_dump($firstname);
              $email = $row['email'];
              $_SESSION['email']= $email;
              var_dump($email);
              mysql_query("UPDATE user SET last_log_date=now() WHERE user_id='$id'");

              header("Location: profile.php");    

          }//close while

      }//close if
