3. 11.x core/lib/Drupal/Core/Field/Plugin/Field/FieldFormatter/EntityReferenceFormatterBase.php \Drupal\Core\Field\Plugin\Field\FieldFormatter\EntityReferenceFormatterBase::getEntitiesToView()

Returns the referenced entities for display.

The method takes care of:

• checking entity access,
• placing the entities in the language expected for display.

It is thus strongly recommended that formatters use it in their implementation of viewElements($items) rather than dealing with $items directly.

For each entity, the EntityReferenceItem by which the entity is referenced is available in $entity->_referringItem. This is useful for field types that store additional values next to the reference itself.

Parameters

\Drupal\Core\Field\EntityReferenceFieldItemListInterface $items: The item list.

string $langcode: The language code of the referenced entities to display.

Return value

\Drupal\Core\Entity\EntityInterface[] The array of referenced entities to display, keyed by delta.
