Joomla 2.5檢查用戶登錄

Question

如何檢查用戶是否在Joomla 2.5中登錄？我似乎只能找到舊版joomla的代碼片段。它是一樣的嗎？

Answer 1

if(JFactory::getUser()->id) 
{ 
//user has logged in 
} 

Answer 2

是的，它像以前一樣嘗試這個 -

$user =& JFactory::getUser(); 
if($user->id!=0){ 
//user is logged in 
} 

Answer 3

$user = JFactory::getUser()->guest; 

如果你是PHP 5.3。
