Why data is not send by form submitting (zf2 forms + filters)? - zend-framework2

Question

I have problem:
When I fill in form and pressing add button page is reloaded, but no data is added to the database.
Code of NewsController, add action is below:
public function addAction() {
$form = new AddNewsForm();
$form->get('submit')->setValue('Add1');
$request = $this->getRequest();
if ($request->isPost()) {
$form->setData($request->getPost());
var_dump($form->isValid());
if ($form->isValid()) {
echo "form is valid";
$objectManager = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
$blogpost = new NewsItem();
$blogpost->exchangeArray($form->getData());
$blogpost->setCreated(time());
$blogpost->setUserId(0);
$objectManager->persist($blogpost);
$objectManager->flush();
// Redirect to list of blogposts
return $this->redirect()->toRoute('news');
}
}
return array('form' => $form);
}
Class AddNewsForm is included as use \News\Form\AddNewsForm as AddNewsForm; above.
I tried to debug my code and realized, that $form->isValid() return false all time. I tried to fill in all fields of form — it says that form is not valid. If not all fields are filled in it false too.
The problem is with validation, I think, so I will add here how I assing filter to the form. This is how I assing filter to my form:
$this->setInputFilter(new AddNewsInputFilter());
Class AddNewsInputFilter is included by this:
use \News\Form\AddNewsInputFilter as AddNewsInputFilter;
I don't think it is good to paste there ~100 lines of code, so I will just give a link to files in my github repo (full code of controllers/files available here):
AddNewsForm.php — file, where I create the form
AddNewsInputFilter.php — file, where I set fil
NewsController.php — file, controller, where I call created form
Repository link — root dir of my module
So the problem is that $form->isValid(); doesn't show is form valid or not properly and I don't know why. Note, that request is getting properly and first condition is passed (but second is not passed). It is the problem, thats why I am writing here.
How I can solve it?
Thanks is advance!

Answer 1

try var_dump($form->getMessages()) and var_dump($form->getInputFilter()->getMessages()) in controller(after calling $form->isValid()) or in view . see what error you getting and on witch element ?
NOTICE : getMessages() will be empty if $form->isValid() has not been called yet,
UPDATE : do this in controller :
var_dump($form->isValid());
var_dump($form->getMessages())
var_dump($form->getInputFilter()->getMessages())
