  2. 9 core/lib/Drupal/Core/Entity/ContentEntityForm.php \Drupal\Core\Entity\ContentEntityForm::flagViolations()

Flags violations for the current form.

If a custom entity form adds some fields to the form (i.e. without using the form display), it needs to add its fields to array returned by getEditedFieldNames() and overwrite this method in order to show any violations for those fields; e.g.:

foreach ($violations
  ->getByField('name') as $violation) {
  $form_state
    ->setErrorByName('name', $violation
    ->getMessage());
}
parent::flagViolations($violations, $form, $form_state);

Parameters

\Drupal\Core\Entity\EntityConstraintViolationListInterface $violations: The violations to flag.

array $form: A nested array of form elements comprising the form.

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form.

ContentEntityForm::validateForm in core/lib/Drupal/Core/Entity/ContentEntityForm.php
Button-level validation handlers are highly discouraged for entity forms, as they will prevent entity validation from running. If the entity is going to be saved during the form submission, this method should be manually invoked from the button-level…
