示例1: viewElements
/**
* {@inheritdoc}
*/
public function viewElements(FieldItemListInterface $items, $langcode)
{
$element = [];
// As the Field API only applies the "field default value" to newly created
// entities, we'll apply the default value for existing entities.
if ($items->count() == 0) {
$field_default_value = $items->getFieldDefinition()->getDefaultValue($items->getEntity());
$items->status = $field_default_value[0]['status'];
}
