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()).
$module
[, string $controller
[, string $action
[, array $paramters
]]] )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
<?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"));
}
}
?>
Example #2 Dummy_action.php
<?php
class DummyAction extends Yaf_Action_Abstract {
/* a action class shall define this method as the entry point */
public execute() {
}
}
?>
