function field_attach_validate

Performs field validation against the field data in an entity.

Parameters

\Drupal\Core\Entity\EntityInterface $entity: The entity with fields to validate.

array $options: An associative array of additional options. See field_invoke_method() for details.

Throws

Drupal\field\FieldValidationException If validation errors are found, a FieldValidationException is thrown. The 'errors' property contains the array of errors, keyed by field name, language and delta.

Code

  // Let other modules validate the entity.
  // Avoid module_invoke_all() to let $errors be taken by reference.
