Validate a set of constraints against a value.

This validator method is a copy of Symfony's AtLeastOneOf constraint. This is necessary because Drupal does not support validation groups.

Parameters

mixed $value: The value to validate.

\Symfony\Component\Validator\Constraint $constraint: The constraint to validate against.

File

core/lib/Drupal/Core/Validation/Plugin/Validation/Constraint/AtLeastOneOfConstraintValidator.php, line 27

Class

AtLeastOneOfConstraintValidator

Validates the AtLeastOneOf constraint.

Namespace

Drupal\Core\Validation\Plugin\Validation\Constraint

Code

public function validate(mixed $value, Constraint $constraint) : void {
  if (!$constraint instanceof AtLeastOneOfConstraint) {
    throw new UnexpectedTypeException($constraint, AtLeastOneOfConstraint::class);
  }
  $validator = $this->context
    ->getValidator();
  // Build a first violation to have the base message of the constraint.
  $baseMessageContext = clone $this->context;
  $baseMessageContext->buildViolation($constraint->message)
    ->addViolation();
  $baseViolations = $baseMessageContext->getViolations();
  $messages = [
    (string) $baseViolations->get(\count($baseViolations) - 1)
      ->getMessage(),
  ];
  foreach ($constraint->constraints as $key => $item) {
    $context_group = $this->context
      ->getGroup();
    if (!\in_array($context_group, $item->groups, TRUE)) {
      continue;
    }
    $context = $this->context;
    $executionContext = clone $this->context;
    $executionContext->setNode($value, $this->context
      ->getObject(), $this->context
      ->getMetadata(), $this->context
      ->getPropertyPath());
    $violations = $validator->inContext($executionContext)
      ->validate($context->getObject(), $item)
      ->getViolations();
    $this->context = $context;
    if (\count($this->context
      ->getViolations()) === \count($violations)) {
      return;
    }
    if ($constraint->includeInternalMessages) {
      $message = ' [' . ($key + 1) . '] ';
      if ($item instanceof All || $item instanceof Collection) {
        $message .= $constraint->messageCollection;
      }
      else {
        $message .= $violations->get(\count($violations) - 1)
          ->getMessage();
      }
      $messages[] = $message;
    }
  }
  $this->context
    ->buildViolation(implode('', $messages))
    ->addViolation();
}
