更改PHP代碼Joomla插件

Question

如何更改代碼，使文本「我是一個快樂的插件」僅出現在已歸檔的項目中？

這是PHP代碼：

<?php 
// No direct access allowed to this file 
defined('_JEXEC') or die('Restricted access'); 

// Import Joomla! Plugin library file 
jimport('joomla.plugin.plugin'); 

//The Content plugin MakePlugIn 
class plgContentMakePlugIn extends JPlugin 
{ 
    function plgContentMakePlugIn (&$subject) 
    { 
     parent::__construct ($subject); 
    } 
    function onPrepareContent (&$article, &$params, $page=0) 
    { 
     print "I am a happy plugin"; 
    } 
} 
?> 

Answer 1

看起來這是你在找什麼：

function onPrepareContent (&$article, &$params, $page=0) 
{ 
    if ($article->state==-1) { 
     print "I am a happy plugin"; 
    } 
}
