Symfony 4 using Validator, how to find out which field the request came from?

Question

symfony

Good afternoon forum!
Can anyone tell me how to find out from which field in the validator the request is being processed and how can I count the locale in the Validator?
Validator is built on this example:
symfony.com/doc/current/validation/custom_constrai...

Answer 1

To solve your problem, it is better to use groups, as answered above. And the answer to your question:

/** @var ConstraintViolation[] $violations */
$violations = $validator->validate($entity);
foreach ($violations as $violation) {
    $property = $violation->getPropertyPath());
}

Answer 2

there are 3 fields, title_ru, title_de and title_en, if the site is currently working on locale==ru, then title_ru is required to fill in; if locale==en, then title_en is required to be filled in

Use validation groups.
One of the options will look something like this.

/**
 * @Assert\NotBlank(groups={"foo_en"})
 */
private $title_ru;

$builder->add('title_ru', null, ['validation_groups' => sprintf('foo_%s', $options['locale'])])

$resolver->setDefaults([
  'locale' => 'en'
]);

$this->createForm(AcmeFormType::class, $object, ['locale' => $request->get('_locale')]);
