ZendFramework 2.0.0rc3 form - php

Question

I try to validate with the form but I cant get error messages.
//this is my code:
$form = new TestForm();
$form->setInputFilter(new TestFilter());
$data = array('id'=>'','email'=>'myemail#myemail.com');
$form->setData($data);
if($form->isValid()){
echo 'ok';
} else {
echo 'not ok <br/>';
$messagesForm = $form->getMessages();
$filter=$form->getInputFilter();
$messagesFilter=$filter->getMessages();
var_dump($messagesForm);
var_dump($messagesFilter);
}
/////////////////
Output
not ok
//messagesForm
array
empty
//MessagesFilter
array
'id' =>
array
'isEmpty' => string 'Value is required and can't be empty' (length=36)
_
How is possible? The filter is ok, but I can't get error messages from the form
Could be a bug or I made something wrong?

Answer 1

I have not worked with ZF2 yet but try to add validators to your elements:
use Zend\Validator;
$this->add(array(
'name' => 'id',
'attributes' => array(
'type' => 'text',
'label' => 'Your name',
),
'validator' => new StringLength(array('max'=>20))
));
}

Answer 2

you must specify 'validators', example of a getInputFilter:
use
Zend\InputFilter\InputFilter,
Zend\InputFilter\Factory as InputFactory,
Zend\InputFilter\InputFilterAwareInterface,
Zend\InputFilter\InputFilterInterface;
class User implements InputFilterAwareInterface
{
public function getInputFilter()
{
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$factory = new InputFactory();
$inputFilter->add($factory->createInput(array(
'name' => 'email',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
),
)));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}

You may do it this way by retrieving input filter from your model and then setting it to a form:
...
$form = new ItemForm();
$form->setInputFilter($user->getInputFilter());
$form->setData($params);
if ($form->isValid()) {
...
}
...
