The Yaf_Controller_Abstract class

(Yaf >=1.0.0)


Yaf_Controller_Abstract is the heart of Yaf's system. MVC stands for Model-View-Controller and is a design pattern targeted at separating application logic from display logic.

Every custom controller shall inherit Yaf_Controller_Abstract.

You will find that you can not define __construct function for your custom controller, thus, Yaf_Controller_Abstract provides a magic method: Yaf_Controller_Abstract::init().

If you have defined a init() method in your custom controller, it will be called as long as the controller was instantiated.

Action may have arguments, when a request coming, if there are the same name variable in the request parameters(see Yaf_Request_Abstract::getParam()) after routed, Yaf will pass them to the action method (see Yaf_Action_Abstract::execute()).


These arguments are directly fetched without filtering, it should be carefully processed before use them.

You can also define a action method in a separate PHP script by using this property and Yaf_Action_Abstract.

Example #1 define action in a separate file

class IndexController extends Yaf_Controller_Abstract {
$actions = array(
/** now dummyAction is defined in a separate file */
"dummy" => "actions/Dummy_action.php",

/* action method may have arguments */
public indexAction($name$id) {
/* $name and $id are unsafe raw data */
assert($name == $this->getRequest()->getParam("name"));
assert($id   == $this->_request->getParam("id"));

Example #2 Dummy_action.php

class DummyAction extends Yaf_Action_Abstract {
/* a action class shall define this method  as the entry point */
public execute() {


module name


controller name


current request object


current response object



view engine object
