獲取Joomla用戶ID返回空白頁

Question

我在Joomla 2.5.16，我想要當前的用戶ID和組ID。

以下代碼返回空白頁面，爲什麼？

<?php 

include_once $_SERVER['DOCUMENT_ROOT']."/includes/defines.php"; 
include_once $_SERVER['DOCUMENT_ROOT']."/includes/framework.php"; 

$user = JFactory::getUser(); 
$group_id = &JFactory::group_id(); 
$user_id = $user->get('id'); 

echo $user_id; 
echo $group_id; 


?> 

Answer 1

試試這個

$user =& JFactory::getUser(); 

if (!$user->guest) { 
    echo 'You are logged in as:<br />'; 
    echo 'User name: ' . $user->username . '<br />'; 
    echo 'Real name: ' . $user->name . '<br />'; 
    echo 'User ID : ' . $user->id . '<br />'; 
}
