The Yaf_Controller_Abstract class

(Não há informação de versão disponível, talvez apenas no SVN)

Introdução

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()).

Propriedades

actions

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

Exemplo #1 define action in a separate file

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

    /* action method may have arguments */
    public indexAction($name, $id) {
       assert($name == $this->getRequest()->getParam("name"));
       assert($id   == $this->_request->getParam("id"));
    }
}
?>

Exemplo #2 Dummy_action.php

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