Zend Framework 2 Repopulate form using validated values - php

Question

I have a simple form class setup along with a filter. After submitting the form, if there's a validation error, the validation/filter works and I can dump the filtered values, but the form does not display the cleaned data. In particular, I am testing with StringTrim and StripTags. I can see the trimmed value, but the final form output still shows the original value submitted. How do I use the validated values instead when the form is repopulated?
An example:
Form data submitted string " asdf ".
Dumping form data, $regform->getData() : "asdf"
The above is expected, but the output in the view still shows the spaces: " asdf ".
I appreciate any input. Code is below. Thank you!
Controller code:
public function indexAction ()
{
$this->layout()->pageTitle = "Account Registration";
$regform = new RegForm($data=null);
if($this->request->isPost()){
$data = $this->post;
$regform->setData($data);
$ufilter = new RegFilter();
$regform->setInputFilter($ufilter->getInputFilter());
if($regform->isValid()){
$this->view->result = "ok";
}
else {
$this->view->result = "Not good";
}
var_dump($regform->getData());
}
$this->view->regform = $regform;
return $this->view;
}
RegForm.php
<?php
namespace GWMvc\Form;
use Zend\Form\Form;
use Zend\Form\Element;
use Zend\Form\Fieldset;
use Zend\InputFilter\InputFilterProviderInterface;
use Zend\Session\Container;
class RegForm extends Form
{
public function __construct($data = null, $args = array())
{
parent::__construct('reg-form');
$this->setAttribute('class', 'form form-inline');
$this->setAttribute('role', 'form');
$this->setAttribute('method', 'post');
$this->setAttribute('action','/app/registration/index');

),
'attributes' => array('id' => 'firstname', 'type' => 'text',
'class' => 'regformitem regtextfield')));
$this->add(array(
'name' => 'lastname',
'type' => 'Zend\Form\Element\Text',
'options' => array(
'label' => 'Last Name:'
),
'attributes' => array('id' => 'lastname', 'type' => 'text',

'options' => array(
'csrf_options' => array(
'timeout' => 600
)
)
));
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Submit',
'class' => 'btn btn-default',

}
}
RegFilter.php
<?php
namespace GWMvc\Form;
use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
class RegFilter implements InputFilterAwareInterface
{
public $username;
public $password;
protected $inputFilter;
public function setInputFilter(InputFilterInterface $inputFilter)
{
throw new \Exception("Not used");
}
public function getInputFilter()
{
if (!$this->inputFilter) {
$this->inputFilter = new InputFilter();
$this->factory = new InputFactory();
$this->inputFilter->add($this->factory->createInput(array(
'name' => 'firstname',
'required' => true,
'filters' => array(
array('name' => 'StringTrim'),
array('name' => 'StripTags'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 50,
),
),
),
)));
$this->inputFilter->add($this->factory->createInput(array(
'name' => 'lastname',
'required' => true,
'filters' => array(
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 50,
),
),
),
)));
}
return $this->inputFilter;
}
}
View Script:
<?php
$form = &$this->regform;
$form->prepare();
echo $this->form()->openTag($form);
echo $this->formElement($form->get('csrf'));?>
<div class="form" gwc="regitem">
<?php echo $this->formRow($form->get('firstname')); ?>
</div>
<div class="form" gwc="regitem">
<?php echo $this->formRow($form->get('lastname')); ?>
</div>
EDIT (SOLUTION)
As per the accepted answer below, it was this easy. Here's what I added.
$valid = $regform->isValid();
$regform->setData($regform->getData());
if($valid){
$this->view->result = "ok";
} else {
// not ok, show form again
}

Answer 1

I guess you have to do it manually:
if($regform->isValid()){
$regform->setData ($regform->getData ())->isValid ();
$this->view->result = "ok";
}
