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");
