我有一个登录页面，允许用户输入电子邮件和密码然后提交，系统检查数据是否正确，它会显示个人资料页面，如果不正确，它会显示一条消息，通知用户数据不正确。

但问题是，如果我把 header("Location:profile.php"); 系统不工作，但如果我回显一条消息，通知用户数据正确，浏览器会毫无问题地显示此消息

登录.php

<?php
session_start();
ob_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'");

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

?>

配置文件.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;
?>

尝试这个。

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

 $email = $_POST['email'];
 $pass = $_POST['pass'];

 $email1 = mysql_real_escape_string(strip_tags($email));
 $pass1 = mysql_real_escape_string(strip_tags($pass));
 //$pass = md5($pass);

 $sql = mysql_query("SELECT user_id, email_address, first_name FROM user WHERE email_address='$email1' AND password='$pass1' LIMIT 1") or die("error in user table");
 $login_check = mysql_fetch_assoc($sql)

if($login_check)
{
   $row = $login_check;

      $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'");

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

ob_end_flush()在 php 关闭标签之前使用?>

您可以在那里使用 javascript 在个人资料页面上重定向。因为如果之前打印的任何小错误或任何空格 php header() 函数都可能导致一些问题.. 所以那里有更好的用户 javascript。

用下面的代码检查

?>
<script>
window.location.href="profile.php";
</script>
<?

我对 profile.php 的这一行有疑问

require_once('include/connect.php');

如果 profile.php 的路径有问题，你必须改变你的

header(Location: "xyz/profile.php");

请检查此相对路径是否正确！
