登录页面和配置文件页面重定向系统不显示正确的页面

Question

我有一个登录页面，允许用户提交注册的电子邮件和密码，如果数据正确，那么系统会重定向到个人资料页面，在这里我会遇到问题。

当我尝试提交写入数据时，系统不会将我重定向到个人资料页面。

但如果我回复确认消息表明数据正确，则浏览器会显示此消息

如何解决这个问题？

的login.php

<?php
session_start();
error_reporting(E_ALL);
require_once('include/connect.php');
$message = ""; 
if(!empty($_POST['email']))
{

$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);

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

  if($login_check > 0)
  {
      $row = mysql_fetch_array($sql);

          $id = $row['user_id'];
          $_SESSION['user_id'] = $id;

          $firstname = $row['first_name'];
          $_SESSION['first_name']= $firstname;

          $email = $row['email_address'];
          $_SESSION['email_address']= $email;

          mysql_query("UPDATE user SET last_log_date=now() WHERE user_id='$id'");

        //$message = "correct email and passworddd!!";  
          header("Location: profile.php");    
  }//close if 
  else
  {
      $message = "incorrect Email or Password!!";
      //exit();
  }
}//close if

?>

profile.php

<?php
session_start();
 require_once('include/connect.php'); 


if(isset($_GET['user_id']))
{
    $id=$_GET['user_id'];
    var_dump($id);

}
elseif(isset($_SESSION['user_id']))
{
    $id= $_SESSION['user_id'];
}

else
{
    print "Important  data  are missing";
    print_r($_SESSION);
    exit();

}

$sql = mysql_query("SELECT * FROM user  WHERE user_id='$id'") or die(mysql_error());
$row = mysql_fetch_array($sql);

   $firstname=$row['first_name'];
   $lastname=$row['last_name'];
   $birth_date=$row['birth_date'];
   $registered_date=$row['registered_date'];
   //***************for upload img*****************//
   $check_pic="members/$id/image01.jpg";
   $default_pic="members/0/image01.jpg";
   if(file_exists($check_pic))
   {
       $user_pic="<img src=\"$check_pic\"width=\"100px\"/>";
   }
   else
   {
       $user_pic="<img src=\"$default_pic\">";
   }
   echo $id, $firstname, $birth_date;
?>

简单:)只需将所有这些代码放在内容的顶部，并确保header("Location: profile.php");正在工作的页面上没有任何内容，因为如果有某些内容无法加载。我还建议在exit;

之后使用header("Location: profile.php");
