How can I get array key => errorMessage from $violations. Symfony 4 - php

Question

Here is my code
$arParams = $request->all();
$validator = Validation::createValidator();
$groups = new GroupSequence(['Default', 'custom']);
$constraint = new Assert\Collection([
'name' => new Assert\Length(['min' => 2]),
'city' => new Assert\Length(['min' => 2]),
'email' => new Assert\Email(),
'phone' => new Assert\Length(['min' => 18]),
'message' => new Assert\NotNull()
]);
$violations = $validator->validate($arParams, $constraint, $groups);
If i get some errors, how can I get an array like
['name' => not enough symbols, 'email' => wrong email]?
I tried to use foreach on $violations but cant find all the methods of its elements Phpstorm sign $violation as mixed. I found only $violation->getMessage() and ->getCode()

I recommend you to read this article https://symfony.com/doc/current/validation.html
If validation fails, a non-empty list of errors (class ConstraintViolationList) is returned.
So you can get your list this way:
if ($violations->count() > 0) {
$formatedViolationList = [];
for ($i = 0; $i < $violations->count(); $i++) {
$violation = $violations->get($i);
$formatedViolationList[] = array($violation->getPropertyPath() => $violation->getMessage());
}
}
Couple explanations. We use methods from violation api count() or get a number of violations, and after in for loop we use get($i) for get every violation by index. After we use getPropertyPath() for get path (name of your property) and getMessage() for get message.
