我有以下代码:
public function adminListAction(Request $request)
{
if (!$this->isGranted('ROLE_ADMIN')) {
return new JsonResponse("Not granted");
}
$page = $request->query->get('page', 1);
$criteria = new DocumentaryCriteria();
$criteria->setStatus(DocumentaryStatus::PUBLISH);
$criteria->setSort([
DocumentaryOrderBy::CREATED_AT => Order::DESC
]);
$qb = $this->documentaryService->getDocumentariesByCriteriaQueryBuilder($criteria);
$adapter = new DoctrineORMAdapter($qb, false);
$pagerfanta = new Pagerfanta($adapter);
$pagerfanta->setMaxPerPage(12);
$pagerfanta->setCurrentPage($page);
$items = (array) $pagerfanta->getCurrentPageResults();
$data = [
'items' => $items,
'count_results' => $pagerfanta->getNbResults(),
'current_page' => $pagerfanta->getCurrentPage(),
'number_of_pages' => $pagerfanta->getNbPages(),
'next' => ($pagerfanta->hasNextPage()) ? $pagerfanta->getNextPage() : null,
'prev' => ($pagerfanta->hasPreviousPage()) ? $pagerfanta->getPreviousPage() : null,
'paginate' => $pagerfanta->haveToPaginate(),
];
return new JsonResponse($data);
}
它返回以下内容,注意空对象数组
{“项目”:[ {},{},{},{},{},{},{},{},{}],“count_results”:9,“current_page”:1,“number_of_pages”: 1、“下一个”:空,“上一个”:空,“分页”:假}
通过这样做,我知道它们的属性不为空:
foreach ($items as $item) {
echo $item->getTitle();
}
// 返回“纪录片 1”
