ZF2 Captcha check is ignored when using input filter

I have a form in my ZF2 application with a CAPTCHA element like this:

$this->add(array(
        'type' => 'Zend\Form\Element\Captcha',
        'name' => 'captcha',
        'attributes' => array(
            'class'=>'form-control',
        ),
        'options' => array(
            'label' => 'Please verify you are human.',
            'captcha' => array('class' => 'Dumb')
        ),
    ));

I have an input filter attached to a form that validates other elements in the form (name, email, message). When it is attached to a form, validation for the CAPTCHA field is ignored on validation.

if ($request->isPost()) {          
        // set the filter
        $form->setInputFilter($form->getInputFilter());
        $form->setData($request->getPost());
        if ($form->isValid()) { ...

If I remove the input filter, then the CAPTCHA field is validated correctly, but obviously the other fields don't have validators. What stupid mistake am I making? Is there a way to validate the "CAPTCHA" that I have to set in the input filter?

The problem is I am assuming that in your form, you have created a method called:

getInputFilter ();

which overrides the original getInputFilter (),

there are two solutions:



rename your function in your form to get getInputFilterCustom ()

and then change also:

if ($request->isPost()) {          
    // set the filter
    $form->setInputFilter($form->getInputFilterCustom());

or inside your current getInputFilter () add logic to validate captcha.

This is my code for adding captcha image control in ZF2 form: 

        $this->add(array(
                'name' => 'captcha',
                'type' => 'Captcha',
                'attributes' => array(
                        'id'    => 'captcha',
                        'autocomplete' => 'off',
                        'required'     => 'required'
                ),
                'options'    => array(
                        'label' => 'Captcha :',
                        'captcha' => new \Zend\Captcha\Image(array(
                            'font' => 'public/fonts/arial.ttf',
                            'imgDir' => 'public/img/captcha',
                            'imgUrl' => 'img/captcha'               
                        ))
                ),
        ));


Other form elements use validators from the input filter, but I haven't used any validators to get it to work.



Hope this helps you.

This is because you are not calling the parent getInputFilter () inside yours. Just do

public function getInputFilter()
{
    parent::getInputFilter();

    //... your filters here
}
