     class ExampleForm extends Form implements InputFilterProviderInterface
     {
         public function init()
         {
             $this->add([

                 ],
                 'attributes' => [

                     'class'    => 'form-control',

                 'options' => [

                 ],
             ]);
         }
    
         public function getInputFilterSpecification()
         {
             return [
                 'email' => [
                     'required' => true,
                     'filters'  => [
                         ['name' => 'StringTrim'],
                         ['name' => 'StripTags'],
                     ],
                     'validators' => [
                         ['name' => 'EmailAddress'],
                     ],
                 ],
             ];
         }
     }

     $app->map(['GET', 'POST'], '/', function ($request, $response) {
         $sm = $this['serviceManager'];
         $formElementManager = $sm->get('FormElementManager');
         $form = $formElementManager->get("RKA\ExampleForm");
    
         if ($request->isPost()) {
             $data = $request->post();
             $form->setData($data);
             $isValid = $form->isValid();
             if ($form->isValid()) {
                 echo "Success!";
                 exit;
             }
         }
    
         $this['view']->render($response, 'home.twig', array(
