public function FieldCollectionItem::save in Field collection 8.3

Same name and namespace in other branches

1. 8 src/Entity/FieldCollectionItem.php \Drupal\field_collection\Entity\FieldCollectionItem::save()

Save the field collection item.

By default, always save the host entity, so modules are able to react upon changes to the content of the host and any 'last updated' dates of entities get updated.

For creating an item a host entity has to be specified via setHostEntity() before this function is invoked. For the link between the entities to be fully established, the host entity object has to be updated to include a reference on this field collection item during saving. So do not skip saving the host for creating items.

Parameters

$skip_host_save: (internal) If TRUE is passed, the host entity is not saved automatically and therefore no link is created between the host and the item or revision updates might be skipped. Use with care.
