Forms and success output

Well,

It's a beginner's question but I really don't know what is the best way. I have a basic CRUD (Create, Retrieve, Update and Delete) in my project and I'd like to output some message if succeeded or not in a div inside the same page.

So, basically, I have a form which action is set to the same page and I have a div #statusDiv below this same form which I'd like to output something like Register included with success.

What is the best way for doing this?

• Set a flag in the controller $this->view->flagStatus = 'message' then call it in the view?

Just to make it more clear开发者_开发知识库. It's my code:

//IndexController.php indexAction()

...

//Check if there's submitted data
if ($this->getRequest()->isPost()) {
    ...
    $registries->insert($data);
    $this->view->flagStatus = 'message';
}

Then my view:

....
<?php if ($this->flagStatus) { ?>   
    <div id="divStatus" class="success span-5" style="display: none;">
        <?php echo $this->flagStatus; ?>
    </div>
<?php } ?>
....

In this situation since you're redirecting, the $this->view->flagStatus will be lost. Instead what you should use is the flashMessenger Action helper:

http://framework.zend.com/manual/en/zend.controller.actionhelpers.html

basically you use it just like you are currently, except you'd change:

$this->view->flagStatus = 'message';

to

$this->_helper->flashMessenger->addMessage('message');

after this you'll need to send the flashMessenger object to the view. You should do this in a place that gets executed on every page request so you can send messages to any page:

$this->view->flashMessenger = $this->_helper->flashMessenger;

and then change your view to:

<?php if($this->flashMessenger->hasMessages(): ?> 
    <div id="divStatus" class="success span-5" style="display: none;">
        <?php $messages = $this->flashMessenger->getMessages(); ?>
        <?php foreach($messages as $message): ?>
        <p><?= $message; ?></p>
        <?php endforeach; ?>
    </div>
<?php endif; ?>

Hope this helps!
