Dear all,
I have a couple of questions related to ZF's FlashMessenger and
Controller plugins.
I have 2 type of messengers, which both extend the FlashMessenger. The
first one is the ResultMessenger,
which I use to notify the user when an action has succeeded. The other
one is the ErrorMessenger. This one
is used to collect error messages, and notify the user when a certain
action has failed.
The code of these classes is pretty simple, as they just change the
default namespace:
ResultMessenger:
class Sanmax_Controller_Action_Helper_ResultMessenger extends
Zend_Controller_Action_Helper_FlashMessenger
{
/**
* $_namespace
*
* @var string
*/
protected $_namespace = 'error';
}
Usage:
$this->_helper->ResultMessenger->addMessage($this->_tmx->_('common.item.saved'));
ErrorMessenger:
class Sanmax_Controller_Action_Helper_ErrorMessenger extends
Zend_Controller_Action_Helper_FlashMessenger
{
/**
* $_namespace
*
* @var string
*/
protected $_namespace = 'error';
}
Usage (from within a model):
$error =
Zend_Controller_Action_HelperBroker::getExistingHelper('ErrorMessenger');
$error->addMessage($tmx->_('error.accompanimentaims.accompaniment_aim'));
I have also written a small controller plugin, which will automaticly
assign the result and error messages to the view:
class Popovggz_Controller_Plugin_Messages extends
Zend_Controller_Plugin_Abstract
{
public function preDispatch()
{
$view =
Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer')->view;
$errors =
Zend_Controller_Action_HelperBroker::getStaticHelper('errorMessenger')->getMessages();
$result =
Zend_Controller_Action_HelperBroker::getStaticHelper('resultMessenger')->getMessages();
$view->messages = array(
'result' => $result,
'error' => $errors
);
}
}
This plugin is registered into the frontcontroller as follows:
$frontController->registerPlugin(new Popovggz_Controller_Plugin_Messages());
The problem which I am now facing, is that the messages do not show up
until the 2nd request.
Take for instance the following code:
class AccompanimentAimsController extends Zend_Controller_Action
{
public function addAction()
{
// snip
if ($this->_request->isPost()) {
// snip
// the validate method adds messages to to ErrorMessages
// when certain errors occur, and returns false if there are
// messages in the current error namespace.
if (!$tslModel->validate()) {
return;
}
}
}
}
The error messages do not show up, until I press the submit button for
the 2nd time, or go to a different controller/action.
Any ideas/suggestions?
Best,
