问题
i upgrade template 2.5 to 3.0, template upgrade but come the following error.
Fatal error: Class 'JParameter' not found in template/theme/index.php on line xxx
回答1:
JParameter was removed in Joomla 3.0 and now either JForm or in most cases JRegistry should be used.
So use the following code, and change to suit your own needs
$jparams = new JRegistry();
$variable = $jparams->get('param_name');
