ZF2 simple form validation - validation

Question

I tried to validate a simple form in zend framework 2 for days now.
I checked the documentation and a lot of posts considering this topic but I found no solution!
I have a very simple form:
class AlimentForm extends Form
{
public function __construct($name = null)
{
parent::__construct('aliment');
$this->add(array(
'required'=>true,
'name' => 'year',
'type' => 'Text',
'options' => array(
'label' => 'Jahr',
),
));
$this->add(array(
'required'=>true,
'name' => 'number',
'type' => 'Text',
'options' => array(
'label' => 'Number',
),
));
$this->add(array(
'name' => 'submit',
'type' => 'Submit',
'attributes' => array(
'value' => 'Go',
'id' => 'submitbutton',
),
));
}
}
I created a custom InputFilter:
namespace Application\Form;
use Zend\InputFilter\InputFilter;
class AlimentInputFilter extends InputFilter {
public function init()
{
$this->add([
'name' => AlimentForm::year,
'required' => true,
'validators' => array(
array(
'name' => 'Between',
'options' => array(
'min' => 1900,
'max' => 3000,
),
),
),
]);
}
}
and finally in my controller I try to validate the form
public function alimentAction(){
$form = new AlimentForm();
$form->setInputFilter(new AlimentInputFilter());
$request = $this->getRequest();
if ($request->isPost()) {
$form->setData($request->getPost());
if ($form->isValid()) {
$year = $form->get('year')->getValue();
$number = $form->get('number')->getValue();
return array('result' => array(
"msg" => "In the Year ".$year." you get ".$number." Points"
));
}
}
return array('form' => $form);
}
It can't be that difficult, but from all those different ways to validate a form I found in the net, I'm a bit confused...
What am I missing?
Greetings and thanks in advance

Ok, I solved the problem.
I created a Model for the aliment Form that has a year and a number attribute
and I defined an input filter within that model:
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
class Aliment implements InputFilterAwareInterface
{
public $year;
public $number;
public function exchangeArray($data){
$this->year = (!empty($data['year']))?$data['year']:null;
$this->number = (!empty($data['number']))?$data['number']:null;
}
public function setInputFilter(InputFilterInterface $inputFilter)
{
throw new \Exception("Not used");
}
public function getInputFilter()
{
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$inputFilter->add(array(
'name' => 'year',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'Between',
'options' => array(
'min' => 1900,
'max' => 3000
)
)
),
));
$inputFilter->add(array(
'name' => 'number',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'Between',
'options' => array(
'min' => 1,
'max' => 10
)
)
),
));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
}
In the action method of the controller I was able to set the InputFilter of the model to the form and voila! It worked!
public function alimentAction(){
$form = new AlimentForm();
$request = $this->getRequest();
if ($request->isPost()) {
$aliment = new \Application\Model\Aliment;
$form->setInputFilter($aliment->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$aliment->exchangeArray($form->getData());
$year = $form->get('year')->getValue();
return array(
'result' => array(
//your result
)
);
}
}
return array('form' => $form);
}
The form is correctly validated now and returns the corresponding error messages.
I hope, it help somebody whos got similar problems with validating!
