在我正在构建的移动网络应用程序中，我一遍又一遍地遇到同样的问题。在我的 index.php 中，如果我的会话中没有设置任何值，我会重定向到 login.php。用户登录后，我重定向回 index.php。我已经通过 PHP 以及通过 JQuery 的 $.mobile.changePage() 方法尝试了标头重定向。

两种方式都会发生什么是首先加载#home的页面划分。当我使用我的导航栏在同一个多页面中更改为新的页面分区时，它会再次加载 login.php。

索引.php

session_start();
require "init.inc"; 
$email = $_SESSION['email'];
if(!isset($email)){header("Location: login.html");}
else{
    echo

您在此处发布的代码存在多个问题。如果我在这里陈述显而易见的事情，请原谅我。

首先，当您提到 login.php 时，您将重定向到 login.html。

改变

if(!isset($email)){header("Location: login.html");}

到

if(!isset($email)){header("Location: login.php");}

其次，不要忘记删除 login.php 中的“/”错字：

 $dbemail = $row['email']; /

顺便说一句，最好不要回显您所有的 HTML 布局代码，我看到您在 index.php 中使用它。

最后：你可以使用

header("Location: index.php");

在您的登录页面和索引页面之间导航没有任何问题。我已经修改了您的代码，它目前位于以下 URL：单击此处进行演示

供您参考，请在下面找到我的（工作）修改后的 login.php 代码：

登录.php

注意：我添加了一个表单来演示功能

<?php
session_start();
require "init.inc";
if(isset($email)){header( "Location: index.php" ); }
$email=$_POST['email']; 
$wachtwoord=$_POST['wachtwoord'];

            $dbemail = $row['email']; 
            $dbwachtwoord = $row['wachtwoord']; 
        }

        if ($email==$dbemail&&$wachtwoord==$dbwachtwoord)
        {


    if ($email){ //not neccessary
