將PHP和Jquery Mobile重定向結合起來返回到前面的頁面

在我正在構建的移動Web應用程序中，我一直得到同樣的問題。在我的index.php中，如果我的會話中沒有設置值，我將重定向到login.php。用戶登錄後，我重定向回index.php。我已經通過PHP以及通過JQuery中的$ .mobile.changePage（）方法嘗試了這一點。將PHP和Jquery Mobile重定向結合起來返回到前面的頁面

這兩種方式會發生什麼？首先是#home的分頁加載。當我使用導航欄切換到同一個多頁面中的新頁面分區時，它會再次加載login.php。

的index.php

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

有與你在這裏發佈的代碼多個問題。所以，如果我在這裏說明明顯的話，不好意思。

首先，您重定向到login.html，而您提到login.php。

變化

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

要

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

其次，不要忘記刪除了「/」錯字中的login.php：

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

順便說一句，這是最佳做法是不要回顯你所有的HTML佈局代碼，我看到你在index.php中使用它。

最後：你可以使用

header("Location: index.php");

沒有任何問題，您的用戶名和索引頁之間進行導航。我修改你的代碼，它目前住在以下網址：click here for a demo

供您參考，找到我的（工作）修改login.php中下面的代碼：

的login.php

注：我添加了一個形式來演示功能

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

* Uncommenting the code below should work for you I suppose           * 
*****************************************************************************************************/ 
if (($email&&$wachtwoord)) 
{ 



/* 
$query = mysql_query("SELECT * FROM user WHERE email='$email'"); 
$numrows = mysql_num_rows($query); 
if ($numrows!=0)//als het aantal rijen niet 0 is 
    { 
     while($row = mysql_fetch_assoc($query))//zolang er rijen zijn 
     { 
      $dbid = $row['userId']; 
      $dbemail = $row['email']; 
      $dbwachtwoord = $row['wachtwoord']; 
     } 

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


    if ($email){ //not neccessary 
       */
