protected ContentEntityForm::flagViolations(EntityConstraintViolationListInterface $violations, array $form, FormStateInterface $form_state)
Flags violations for the current form.
If the entity form customly adds some fields to the form (i.e. without using the form display), it needs to add its fields to array returned by getEditedFieldNames() and overwrite this method in order to show any violations for those fields; e.g.:
foreach ($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.
