how to dynamically set cascade validation of form from controller - symfony

Question

My form looks like this :
class CpanelRetailerForm extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('name', 'text', array(
'attr' => array(
'class' => 'text-input',
'size' => '50'
),
'required' => false
))
->add('email', 'email', array(
'attr' => array(
'class' => 'text-input',
'size' => '50'
),
'required' => false
))
->add('addUser', 'checkbox', array(
'label' => 'Add User account',
'required' => false,
'mapped' => false
))
->add('user',new CpanelUserForm());
}
public function setDefaultOptions(OptionsResolverInterface $resolver) {
$resolver->setDefaults(array(
'data_class' => 'Acme\TestBundle\Entity\Retailer',
//'cascade_validation' => true
));
}
public function getName() {
return 'retailer';
}
}
I want to dynamically set this line from controller depending on whether addUser field is checked or unchecked.
cascade_validation' => true
Here is my controller code:
$form = $this->createForm(new CpanelRetailerForm(), new Retailer());
$form->
if ($this->getRequest()->isMethod('POST')) {
$form->bind($this->getRequest());
if ($form->get('addUser')->getData()) {
// then set the cascade_validation to true here
}
}
How can I do this inside controller?
My attempt :
added this line in my form class:
$builder->addEventListener(
FormEvents::POST_SUBMIT, function(FormEvent $event) {
$form = $event->getForm();
$addUser = $form->get('addUser')->getData();
$validation = false;
if ($addUser) {
$validation = true;
}
$resolver = new OptionsResolver();
$resolver->setDefaults(array(
'cascade_validation' => $validation
));
$this->setDefaultOptions($resolver);
}
);
This didnot work for me. Although I receive data in $addUser, cascade_validation is not added

How can I do this inside controller?
You can´t! Thats the simple answer. Lets take a look at following simple form class:
class TestType extends AbstractType {
/**
* #var boolean
*/
private $myOption;
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options) {
$this->myOption = false;
$builder
->addEventListener(FormEvents::POST_SET_DATA, function(FormEvent $event) {
dump('formEvents::PRE_SET_DATA');
})
->addEventListener(FormEvents::PRE_SET_DATA, function(FormEvent $event) {
dump('FormEvents::POST_SET_DATA');
})
->addEventListener(FormEvents::PRE_SUBMIT, function(FormEvent $event) {
dump('FormEvents::PRE_SUBMIT');
})
->addEventListener(FormEvents::SUBMIT, function(FormEvent $event) {
dump('FormEvents::SUBMIT');
})
->addEventListener(FormEvents::POST_SUBMIT, function(FormEvent $event) {
dump('formEvents::POST_SUBMIT');
})
->add('name', TextType::class)
->add('send', SubmitType::class);
}
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver) {
$resolver->setRequired(array(
'my_option'
));
$resolver->setDefaults(array(
'my_option' => $this->setMyOption()
));
}
/**
* #return bool
*/
public function setMyOption() {
dump($this->myOption);
return $this->myOption;
}
}
Lets take in how you render and handle a form inside a Controller:
public function formAction(Request $request) {
$form = $this->createForm(TestType::class);
dump('calledCreateForm');
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
dump('finished');
dump($form->getData());
die();
}
return $this->render('#TestPra/Test/test_form.html.twig', array(
'form' => $form->createView()
));
}
After submitting the form you get the following output order:
$this->setMyOption() > null
FormEvents::PRE_SET_DATA
FormEvents::POST_SET_DATA
calledCreateForm
FormEvents::PRE_SUBMIT
FormEvents::SUBMIT
FormEvents::POST_SUBMIT
finished
The first thing allways gets called is configureOptions and because you don´t have any data of the filled form before calling handleRequest there is no way to change the options of the allready created form without manipulating Symfonys form component.
