PHP的子文件夾中的會話範圍與AJAX

我有一個用戶登錄會話運行在/級，這工作正常，然後我有一個JavaScript調用文件/ PHP/AJAX.PHP與數據庫後端。事情是我想從初始登錄/級別轉移到ajax.php會話數據，它沒有。有關於這個話題的任何合理的想法？PHP的子文件夾中的會話範圍與AJAX

頁檢查登錄：

<?php 
session_start(); 
echo session_id(); 
if(!isset($_SESSION['loggedin'])) 
{ 
    die("To access this page, you need to <a href='login.php'>LOGIN</a>"); 
} 

define('WP_USE_THEMES', false); //loads wordpress 
require('/home/content/70/9551370/html/alpha/wordpress/wp-blog-header.php'); 
query_posts('showposts=1');

請寄一些代碼！ –

<？php session_start（）;？> ...等待 –

@ TimZhukov-Khovanskiy在下面看到我的答案。 – Matt

把session_start()在需要訪問會話的所有文件的開始。

<?php //very first line of file (ajax.php, index.php, whatever.php) 
session_start(); 
// other PHP scripting here 
. 
. 
. 
?> 
<!-- HTML here if necessary --> 
. 
. 
.

這不起作用。事實上，在jscript調用ajax.php後，會話ID是不同的。 –

會話開始我有login.php： <？php session_start（）; //獲取會話變量 > <標籤即JavaScript的職位，並從> 得到的東西然後ajax.php –
