Use the FlashMessenger action helper in conjunction with the Redirector.
Usage is very simple. In your action that handles the form, do something
like:
// Add a message
$this->_helper->flashMessenger->addMessage('success!');
// Redirect
// Provide the name of the next action; when used like this, it acts
// like _forward(), but issues a redirect:
$this->_helper->redirector('next'); //
Then, in the action to which you redirected:
$flash = $this->_helper->getHelper('flashMessenger');
if ($flash->hasMessages()) {
$this->view->messages = $flash->getMessages();
}
Note that the assumption is that there may be multiple messages, so an
array of messages will be returned; simply grab the first one if you
know there will only ever be one:
<?= $this->escape($this->messages[0]) ?>
