Joomla 1.7版 管理部分启用了插件
插件代码:
<?php
// no direct access
defined('_JEXEC') or die;
jimport('joomla.plugin.plugin');
class plgSystemMetatags extends JPlugin
{
public function __construct(&$subject, $config)
{
parent::__construct($subject, $config);
}
public function onBeforeRender()
{
$document =& JFactory::getDocument();
$document->setMetaData('keywords', 'test keywords');
}
}
但这不起作用
元描述呈现值,在全局配置中设置
