如何创建会话变量并显示另一个页面

在index.php中，我在jQuery中设置了一个会话变量，并且在此页面中获取了我的令牌ID，但我想将其显示在另一个页面（如home.php）中。所以我在home.php页面做如何创建会话变量并显示另一个页面

var val = $.session.get('Token'); 
    alert(); //**getting here undefined**.how can solve this issue please tell me any one

(function($){ 
 

 
    $.session = { 
 

 
     _id: null, 
 

 
     _cookieCache: undefined, 
 

 
     _init: function()

      if (!window.name) { 
 
       window.name = Math.random(); 
 
      } 
 
      this._id = window.name; 
 
      this._initCache(); 
 

 
      // See if we've changed protcols 
 

 
      var matches = (new RegExp(this._generatePrefix() + "=([^;]+);")).exec(document.cookie); 
 
      if (matches && document.location.protocol !== matches[1]) { 
 
       this._clearSession(); 
 
       for (var key in this._cookieCache) { 
 
        try { 
 
        window.sessionStorage.setItem(key, this._cookieCache[key]); 
 
        } catch (e) {}; 
 
       } 
 
      } 
 

 
      document.cookie = this._generatePrefix() + "=" + document.location.protocol + ';path=/;expires=' + (new Date((new Date).getTime() + 120000)).toUTCString(); 
 

 
     }, 
 

 
     _generatePrefix: function() 
 
     {

你为什么不使用一些lib或jQuery插件用饼干代替$ .session是一串代码工作？例如，https://github.com/js-cookie/js-cookie –

为什么不只是使用标准会话cookie来存储和检索信息？ –

措辞，首都 – Mikkel

您可以创建一个应包括在所有其他文件（家在一个文件（header.php文件）会话变量。在这种情况下，PHP）

所以，像这样的

的header.php创建会话

<?php 
    session_start(); 
    if (isset($_SESSION['username'])) { 
     // session already exists 
     echo "User ID:", $_SESSION['id'], "<br />" 
    } else { 
     // New PHP Session 

     $_SESSION['username'] = "loginprocess"; 
     $_SESSION['id'] = 444; 
    } 
?>

可能home.php

<?php require "header.php"; ?> 
<!doctype html> 
<head></head> 
<body> 
<?php 
    if (isset($_SESSION["username"])) { 
     $loggenOnUser = $_SESSION["username"]; 
     echo "Existing User: ", $loggenOnUser, "<br />" 
    } else { 
     $loggenOnUser = " new user"; 
    } 
?> 
    ... 
     <div id="LoggedInUser" class="fluid "> 
      Hi. I'm <?php echo $loggenOnUser; ?> 
     </div>

编辑：

尝试移动您的会话初始化代码要么的header.php或footer.php，包括在每一个其他PHP页面页眉和页脚，这将允许访问每个页面中的会话变量。

包含在其他页面，如标题和footer.php home.php这样的：

<?php require "header.php"; ?> 
. 
. 
//Body 
. 
. 
<?php require "footer.php"; ?>
