【问题描述】:
我正在开发一个 Symfony 2 项目,我使用了 KnpPaginatorBundle,第一页正常工作,但第二页显示此错误:“控制器必须返回响应(给定 null)。您是否忘记添加返回语句在你的控制器的某个地方?“我不明白这个请帮助我
这是我的控制器:
public function searchAction(Request $request) {
$search_form = $this->createForm(new SearchInterventionBatimentType());
if ($request->isMethod('post')) {
$search_form->handleRequest($request);
if ($search_form->isValid()) {
$data = $search_form->getData();
$from = $data['from'];
$to = $data['to'];
$intervenant= $data['intervenant'];
$type= $data['type'];
$batiment = $data['batiment'];
$em = $this->getDoctrine()->getManager();
$intervention = new InterventionBatiment();
if(is_null($intervenant) && is_null($type) && is_null($batiment)) {
$intervention = $em->getRepository('SecteurBundle:InterventionBatiment')->findByDate($from,$to);
} elseif(is_null($type) && is_null($batiment)) {
$intervention = $em->getRepository('SecteurBundle:InterventionBatiment')->findByDateAndIntervenant($from,$to,$intervenant);
} elseif (is_null($intervenant) && is_null($batiment)) {
$intervention = $em->getRepository('SecteurBundle:InterventionBatiment')->findByDateAndType($from,$to,$type);
} elseif (is_null($intervenant) && is_null($type)) {
$intervention = $em->getRepository('SecteurBundle:InterventionBatiment')->findByDateAndBatiment($from,$to,$batiment);
} elseif (is_null($batiment)) {
$intervention = $em->getRepository('SecteurBundle:InterventionBatiment')->findByDateAndIntervenantAndType($from,$to,$type,$intervenant);
} else {
$intervention = $em->getRepository('SecteurBundle:InterventionBatiment')->findByAll($from,$to,$type,$intervenant,$batiment);
}
$paginator= $this->get('knp_paginator');
$result= $paginator->paginate(
$intervention, /* query NOT result */
$request->query->getInt('page', 1)/*page number*/,
$request->query->getInt('limit', 8)/*limit per page*/
);
return $this->render(
'SecteurBundle:InterventionBatiment:recherche.html.twig',
array('interventions' => $result,'form' => $search_form->createView())
);
}
}
}
