add Symfony Assert in a Callback - validation

Question

I, i have to add an Assert to an atribute when other atribute is equal than something. Like this:
/**
* #Assert\Callback(methods={"isChildMinor",)
*/
class PatientData
{
/**
* #Assert\Date()
*/
public $birthday;
public $role;
public function isChildMinor(ExecutionContext $context)
{
if ($this->role == 3 && check #assert\isMinor() to $birtday) {
=>add violation
}
}
so, i want check if the patient is minor (with assert or somethings else) if the role is equal than 3. How do this?

There are several ways to do, what you want.
1) You could make it right in the form. Like that:
use Symfony\Component\Validator\Constraints as Assert;
public function buildForm(FormBuilderInterface $builder, array $options)
{
$yourEntity = $builder->getData();
//here you start the field, you want to validate
$fieldOptions = [
'label' => 'Field Name',
'required' => true,
];
if ($yourEntity->getYourProperty != 'bla-bla-bla') {
$fieldOptions[] = 'constraints' => [
new Assert\NotBlank([
'message' => 'This is unforgivable! Fill the field with "bla-bla-bla" right now!',
]),
],
}
$builder->add('myField', TextType::class, $fieldOptions);
2) Other way - is to make your custom validation callback in your Entity and play with direct asserts there. It's possible, I think.
3) But the optimal way, from my point of view - is to use several asserts with validation groups. You need to specify Assert\isMinor(groups={"myCustomGroup"}) on birthday field. And then, in your form:
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'validation_groups' => function (FormInterface $form) {
$yourEntity = $form->getData();
if ($yourEntity->role !== 3) {
return ['Default', 'myCustomGroup'];
}
return ['Default'];
},
Hope this'll be helpful for you.
