Question

I am trying to do simple contact us page with flashmessenger helper plugin.
I have implemented it as below, but my problem is i have to submit the form twice to get the flashmessagers showing in the page.
What i am i doing wrong here ..
show the messages on the first submit ?
how do i hide the form the after submit ?
in my controller
// Add content to this method:
public function contactAction()
{
$form = new ContactForm();
$form->get('submit')->setValue('Submit');
$request = $this->getRequest();
if ($request->isPost()) {
$contact = new Contact();
$form->setInputFilter($contact->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$data=$form->getData();
//var_dump($data);
$mail = new Mail\Message();
$mail->setBody($data['comment'])
->setFrom($data['email'], $data['name'])
->addTo(IEMAIL, COMPANY )
->addReplyTo($data['email'], $data['name'])
->setSubject($data['subject']);
$transport = new Mail\Transport\Sendmail();
$transport->send($mail);
$this->flashMessenger()->addMessage('Thanks you for the submission ');
}
else{
$this->flashMessenger()->addMessage('Opps somethinge went wrong ..!');
}
}
/**/
return new ViewModel(array(
'customMessage' => 'Welcome to the sales',
'form' => $form
));
}
IN my view i have the coding as
<?php
$title = 'Contact Us';
$this->headTitle($title);
?>
<h1><?php echo $this->escapeHtml($title); ?></h1>
<?php echo $this->customMessage ?>
<?php
if ($this->flashMessenger()->hasMessages()):
echo $this->flashMessenger()->render('success', array('alert', 'alert-danger'));
// In any of your .phtml files:
$flash = $this->flashMessenger();
$flash->setMessageOpenFormat('<div%s>
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">
×
</button>
<ul><li>')
->setMessageSeparatorString('</li><li>')
->setMessageCloseString('</li></ul></div>');
echo $flash->render('error', array('alert', 'alert-dismissable', 'alert-danger'));
echo $flash->render('info', array('alert', 'alert-dismissable', 'alert-info'));
echo $flash->render('default', array('alert', 'alert-dismissable', 'alert-warning'));
echo $flash->render('success', array('alert', 'alert-dismissable', 'alert-success'));
?>
<? endif ?>
<?php
$form->setAttribute('action', $this->url('contact', array('action' => 'submit')));
$form->prepare();
echo $this->form()->openTag($form);
echo $this->formRow($form->get('name'));
echo $this->formRow($form->get('email'));
echo $this->formRow($form->get('subject'));
echo $this->formRow($form->get('comment'));
echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();

Answer 1

The flash messenger does not work in the way you are expecting. It is designed for showing messages to the user after a redirect. To do this it adds any messages you pass to it to a session container so they can be retrieved on the next request. This behaviour (Post/Redirect/Get) is a common pattern in web applications as it reduces of the chance of a user accidentally re-submitting form submissions by refreshing the page.
If you add a redirect after your $transport->send($mail);, then the successful submissions should work how you expect. For the failed ones to work you'll need to write your own helper that does same-request messaging as well (which is what I normally do). Instead you might want to get rid of the fail message and just let the form's inbuilt error messaging do its thing.

Change this code in controller...
$message = '';
$flashMessenger = $this->flashMessenger();
if ($flashMessenger->hasMessages()) {
$message = $flashMessenger->getMessages();
}
And in View
<?php if(is_array($message) && count($message) > 0){
foreach($message as $messageKey => $messageValue){?>
<div style= "color:red"> <?php echo $messageValue; ?> </div>
<?php } } ?>
