Hi Expert, having problems about Phalcon\Forms\form after submitting data to form got error

(the form) bizRegisterForm.php

<?php
use Phalcon\Forms\Form;
use Phalcon\Forms\Element\Text;
use Phalcon\Forms\Element\Select;
use Phalcon\Validation\Validator\PresenceOf;
use Phalcon\Validation\Validator\Email;

class bizRegisterForm extends Form
{
  public function initialize($entity = null, $options = null)
  {
    $businessname = new Text('businessname', [
      'placeholder' => 'Use Your Business Trading name'
    ]);
    $businessname->setFilters(['string']);
    $businessname->addValidators([
      new PresenceOf([
        'message' => 'The Business Name is required'
        ])
    ]);
    $this->add($businessname);

    $businessemail = new Text('businessemail', [
      'placeholder' => 'e.g. [email protected]'
    ]);
    $businessemail->setFilters(['email']);
    $businessemail->addValidators([
      new PresenceOf([
        'message' => 'The business e-mail is required'
        ]),
      new Email([
        'message' => 'The business e-mail is not valid'
        ]),
    ]);
    $this->add($businessemail);
  }
}

The Controller

<?php
class BusinessController extends ControllerBase
{
  public function indexAction()
  {
      $form = new registerForm();
     // other code ../
     $this->view->form = $form
  }

  public function registerAction()
  {
    $registerform = new bizRegisterForm;
    if($this->request->isPost())
    {
      $bussiness->business_name     = $this->request->getPost('businessname');
      $bussiness->phone             = $this->request->getPost('businessphone');
     // other code ...
      if($bussiness->save())
      {
        $this->flash->success('fyes please');
      }
      $this->flash->error($bussiness->getMessages());
    }
    $this->view->form = $registerform;
  }
}

register.volt

{{form('id':'register-form', 'class':'form')}}
        <div class="form-group">
         {{form.render("businessname")}}
        </div>
    <div class="form-group">
    {{form.render('businessphone')}}
    </div>
    // the rest of the code
    <div class="form-group">
         <button autocomplete="off" class="button button-full button-primary" type="submit">
          <span class="button-text">Next</span>
         </button>
        </div
{{end_form()}}

Looks like you have return statement before view var "form" assignment. Try to move $this->view->form = $registerform; before if($this->request->isPost()) if you didn't changed $registerform there

Thank you @Boris for fast respons and apologize for late replay. yep this is work like a charms now BUT the form cannot work anymore for full syntax

  public function registerAction()
  {

    /** Get session info */
    $auth             = $this->session->get('auth');
    /** Query the active user */
    $user             = Users::findFirst($auth['id']);
    /** get register form @ bizRegisterForm*/
    $registerform     = new bizRegisterForm();
    // tHE BORIS way :) IT WORKS
    $this->view->form = $registerform;
    //But this form not work anymore
    if($this->request->isPost())
    {
      /** get Business model from Business model */
      $bussiness                    = new Business();
      $bussiness->users_id          = $user->id;
      $bussiness->business_name     = $this->request->getPost('businessname');
      $bussiness->phone             = $this->request->getPost('businessphone');
      $bussiness->email             = $this->request->getPost('businessemail');
      $bussiness->suburb            = $this->request->getPost('businesssuburb');
      $bussiness->business_state_id = $this->request->getPost('businessState');
      $bussiness->postcode          = $this->request->getPost('postcode');

      if($bussiness->save())
      {
        /**saving and redirect...*/
        return $this->response->redirect('complete-business');
      }
      $this->flash->error($bussiness->getMessages());
    }
  }

Since you are using form, there are no need to bind variables to model manually, you can simply do it like that way: (For user binding you can use form callback beforeValidation()/afterValidation() or bind it after form validation)

<?php

    public function registerAction()
    {
        /** Get session info */
        $auth = $this->session->get('auth');
        /** Query the active user */
        $user = Users::findFirst($auth['id']);
        /** get register form @ bizRegisterForm*/
        $registerForm = new bizRegisterForm();

        if ($this->request->isPost()) {

            $business = new Business();

            $registerForm->bind($this->request->getPost(), $business);

            if ($registerForm->isValid()) {
                $business->user_id = $user->id;

                if ($business->save()) {
                    $this->flash->error($business->getMessages());
                } else {
                    return $this->response->redirect('complete-business');
                }

            } else {
                foreach ($registerForm->getMessages() as $message) {
                    $this->flash->error($message->getMessage());
                }
            }
        }

        $this->view->form = $registerForm;
    }
