Zend Framework 2 Form Errors Not Showing

Question

I am trying to figure out why Zend Form is not returning errors to my form.

When I take a look inside the: Zdendframework/library/form/form.php file I can see the errors are being generated:

public function isValid()
    {
        if ($this->hasValidated) {
            return $this->isValid;
        }

       ...


        if (!$result) {
            $this->setMessages($filter->getMessages());
        }

        return $result;
    }

If I var_dump($filter->getMessages(), I see the errors.

However when I go back to my form and attempt to dump the messages, there are none available.

My Controller

        $prg = $this->prg();

    if ($prg instanceof Response) {

        return $prg;

    } elseif ($prg === false) {

        return $this->getVM()->setVariables([
            'form' => $this->registerForm
        ]);

    }

    $this->registerForm->setData($prg);


    if ( ! $this->registerForm->isValid($prg) ) {

        return new ViewModel(['form' => $this->updateForm]);
    }

My form:

public function __construct(
        InputFilterInterface $inputFilter,
        $name = null,

        $this->register = $inputFilter;
    }

    public function init()
    {
        $this->add(
            [
                'name' => 'csrfcheck',
                'type' => 'csrf'
            ]
        );

        $this->add(

        );

        $this->add(

            ]

        $this->getInputFilter()->add($this->register, 'user');

        $this->setValidationGroup(

                </div>
                <?= $this->form()->closeTag(); ?>

EDIT

In the controller if I dump this:

    $result = $this->registerForm->getInputFilter()->getMessages();

    die(var_dump($result));

This outputs:

array (size=1) 'user' => array (size=1) 'firstName' => array (size=1) 'isEmpty' => string 'Value is required and can't be empty' (length=36)

Once you have called isValid() if you then dump $this->registerForm->getInputFilter()->getMessages() what do you see? — Ankh

I see the error message when I dump it... I have added it to the opening post. — HappyCoder

Found the error. Its in the controller, I am returning the wrong form on failure. If you add that as your answer, I will give it to you since your suggestion lead me to it. — HappyCoder

As deduced from the comments and HappyCoder themselves, the problem lies in the Controller where the wrong form is being returned to the view.

if ( ! $this->registerForm->isValid($prg) ) {
    return new ViewModel(['form' => $this->updateForm]);
}

Should be:

if ( ! $this->registerForm->isValid($prg) ) {
    return new ViewModel(['form' => $this->registerForm]);
}
