<?php class MyFilter extends CFilter { protected function preFilter ($filterChain) { // logic being applied before the action is executed echo "-->MyFilter-->pre"; return true; // false if the action should not be executed } protected function postFilter ($filterChain) { echo "-->MyFilter-->post"; } }
