Question

I am quite new in Symfony2. I am trying to develop a website where someone can register/login. So to i am trying to make the register form but it always thows exception regarding the setDefaultOptions(OptionsResolverInterface $resolver) method.
RegisterType.php:
<?php
namespace MyappBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\NumberType;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class RegisterType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options){
$builder
->add('name', TextType::class, array(
'label' => 'Your Name',
'label_attr' => array(
'attr' => array(
'class' => 'control-label'
)
),
'attr' => array(
'class' => 'form-control'
)
))
->add('email', EmailType::class, array(
'label' => 'Your Email',
'label_attr' => array(
'attr' => array(
'class' => 'control-label'
)
),
'attr' => array(
'class' => 'form-control'
)
))
->add('password',RepeatedType::class, array(
'type' => PasswordType::class, array(
'first_options' => array(
'label' => 'Your Password', array(
'label_attr' => array(
'attr' =>array(
'class'=> 'control-label'
)
)
),
'attr' => array(
'class' => 'form-control'
)
),
'second_options' => array(
'label' => 'Repeat Password', array(
'label_attr' => array(
'attr' =>array(
'class'=> 'control-label'
)
)
),
'attr' => array(
'class' => 'form-control'
)
)
)))
->add('tel', NumberType::class, array(
'label' => 'Your Telephone number',
'label_attr' => array(
'attr' => array(
'class' => 'control-label'
)
),
'attr' => array(
'class' => 'form-control'
)
))
->add('register', 'submit', array(
'attr' => array(
'class' => 'btn btn-default'
)
));
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(['data_class' => 'MyappBundle\Entity\Users']);
}
public function getName(){
return 'register';
}
}
RegisterControler.php
<?php
namespace MyappBundle\Controller;
use MyappBundle\Form\Type\RegisterType;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use MyappBundle\Entity\Users;
use Symfony\Component\HttpFoundation\Request;
class RegisterController extends Controller
{
public function indexAction(Request $request)
{
$user = new Users();
$form = $this->createForm(new RegisterType($user), array(
'action' => $this->generateUrl('myapp_register'),
'method' => 'POST'
));
if($form->isSubmitted() && $form->isValid()){
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
return $this->redirect($this->generateUrl('myapp_homepage'));
}
return $this->render('MyappBundle:Default:register.html.twig', array('form' => $form->createView(),));
}
}
The Error that I get is:
CRITICAL - Uncaught PHP Exception Symfony\Component\OptionsResolver\Exception\UndefinedOptionsException: "The option "0" does not exist. Defined options are: "action", "allow_extra_fields", "attr", "auto_initialize", "block_name", "by_reference", "cascade_validation", "compound", "constraints", "csrf_field_name", "csrf_message", "csrf_protection", "csrf_provider", "csrf_token_id", "csrf_token_manager", "data", "data_class", "disabled", "empty_data", "error_bubbling", "error_mapping", "extra_fields_message", "first_name", "first_options", "inherit_data", "intention", "invalid_message", "invalid_message_parameters", "label", "label_attr", "label_format", "mapped", "max_length", "method", "options", "pattern", "post_max_size_message", "property_path", "read_only", "required", "second_name", "second_options", "translation_domain", "trim", "type", "validation_groups", "virtual"." at C:\Users\Vicky\Documents\My Documents\PROJECTS\VF-HOUSING_SYMFONY\vendor\symfony\symfony\src\Symfony\Component\OptionsResolver\OptionsResolver.php line 760
Can anyone please help me?

Answer 1

I always use the configureOptions method to map my entity to the form. So try this:
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
array(
'data_class' => 'MyappBundle\Entity\Users',
)
);
}

Answer 2

So the problem was solved.
Deleting the following function in RegisterType.php
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
array(
'data_class' => 'MyappBundle\Entity\Users',
)
);
}
and modifying the RegisterControler.php as follows
$user = new User();
$form = $this->createForm(RegisterType::class,$user);
$form->handleRequest($request);
it solves the problem that I mentioned.
Thank you for your help!
