写入过程

复制代码 代码如下:

// Get the path of the configuration file

$fname = JPATH_CONFIGURATION.DS.'configuration.php';

// clear cache

$cache = JFactory::getCache();

$cache->clean();

// Update the credentials with the new settings

$config =& JFactory::getConfig();

$config->setValue('config.custom_var', 'xxx');

// Get the config registry in PHP class format and write it to configuation.php

jimport('joomla.filesystem.file');

if (!JFile::write($fname, $config->toString('PHP', 'config', array('class' => 'JConfig')))) {

die(JText::_('ERRORCONFIGFILE'));

}

提取过程

复制代码 代码如下:

global $mainframe;

$mainframe->getCfg('custom_var');
