I have a controller plugin with postDispatch() hook, and there I have a $variable.
How to pass this variable to the view instance?
I tried Zend_Layout::getMvcInstance()->getView(), but this returns new view instance (not the application resource). The same with $bootstrap->getResource('view').
I don't want to pass it as a request param.
Now, as a workaround I do it using Zend_Registry.
But, is it the best way?
I've been using the ViewRenderer action helper to get the view when I need it. It seems to be the most common way that Zend classes access the view object.
So, in the controller plugin:
class App_Controller_Plugin_ViewSetup extends Zend_Controller_Plugin_Abstract {
public function postDispatch() {
$view = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer')->view;
echo $view->variable;
$view->variable = 'Hello, World';
}
}
In the controller:
class IndexController extends Zend_Controller_Action {
public function indexAction() {
$this->view->variable = 'Go away, World';
}
}
In the view script:
<?php echo $this->variable; ?>
The output is: Go away, WorldGo away, World
It seems like the problem is that the view script renders before the postDispatch() method is called, because this does return the main view object.
in the plugin:
class App_Plugin_MyPlugin extends Zend_Controller_Plugin_Abstract{
public function preDispatch (Zend_Controller_Request_Abstract $request){
$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');
$viewRenderer->setNeverRender(true);
}
public function postDispatch(Zend_Controller_Request_Abstract $request){
$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');
$view = $viewRenderer->view;
$view->variable = 'new value';
$viewRenderer->render();
}
}
In the controller:
class IndexController extends Zend_Controller_Action {
public function indexAction() {
$this->view->variable = 'value';
}
}
In the view script:
<?php echo $this->variable; ?>
The output is: new value
class ZFExt_Controller_Plugin_Passvar extends Zend_Controller_Plugin_Abstract
{
public function postDispatch(Zend_Controller_Request_Abstract $request)
{
$view = Zend_Controller_Front::getInstance()
->getParam('bootstrap')
->getResource('view');
$view->variable = 'Hi there';
}
}
Then in the view script
<p><?php echo $this->variable; ?></p>
