Joomla 3获取用户ID

Question

我在文件夹 myjoomla/myscript/中有此代码

<?php
define('_JEXEC', 1 );
define('JPATH_BASE', $_SERVER['DOCUMENT_ROOT']."" ); 
define( 'DS','/' );

require_once ( JPATH_BASE.DS. 'includes'.DS.'defines.php' );
require_once ( JPATH_BASE.DS.'includes'.DS.'framework.php' );
require(JPATH_BASE.DS.'libraries/joomla/factory.php');

$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();

jimport( 'joomla.session.session' );
$session                =& JFactory::getSession();

$user =& JFactory::getUser();
echo "id:".$user->id;

我打印 JPATH_BASE 并且没问题。但没有打印id，只打印“0”。我在 joomla 中登录正常。这在本地主机中可以，但在服务器中不行。

谢谢

是的，确实，这就像旧代码。新代码如下所示，

<?php
if (!defined('_JEXEC'))
{
    // Initialize Joomla framework
    define('_JEXEC', 1);
}

// Load system defines
if (file_exists(dirname(__FILE__) . '/defines.php'))
{
    require_once dirname(__FILE__) . '/defines.php';
}
if (!defined('JPATH_BASE'))
{
    define('JPATH_BASE', dirname(__FILE__));
}
if (!defined('_JDEFINES'))
{
    require_once JPATH_BASE . '/includes/defines.php';
}

// Get the framework.
require_once JPATH_BASE . '/includes/framework.php';

$app = JFactory::getApplication('site');
$app->initialise();

$user = JFactory::getUser();
echo "id:".$user->id;

注意:在本地和实时测试您的代码，它对我有用。但不太确定为什么它在您的生活环境中不起作用。但你的代码确实很旧。
