變量「filterForm」不存在

Question

我想用一包「PetkoparaMultiSearchBundle」做搜索的形式，但我得到這個錯誤，當我嘗試使用

{{ form_rest(filterForm) }} 

這裏是我的檢索類別把表單上我的樹枝。 PHP

class SearchType extends AbstractType{ 

    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
    $builder->add('search', MultiSearchType::class, array(
     'class' => 'SpoiledCarFrontOfficeBundle:Voiture')); 
    } 
    } 

，這裏是我的控制器

* Search a Voiture . 
* 
* @Route("/profile/shop", name="fos_user_profile_listTable") 
* @Method({"GET", "POST"}) 
*/  
    public function listTableAction(Request $request) 
{ 
$search = $request->get('search'); 
$em = $this->getDoctrine()->getManager(); 
$queryBuilder = $em->getRepository('SpoiledCarFrontOfficeBundle:Voiture')- >createQueryBuilder('e'); 
$filterForm = $this->createForm('SpoiledCarFrontOfficeBundle\Form\SearchType'); 

// Bind values from the request 
$filterForm->handleRequest($request); 

if ($filterForm->isValid()) { 
    // Build the query from the given form object 
    $queryBuilder = $this->get('petkopara_multi_search.builder')->searchForm($queryBuilder, $filterForm->get('search')); 
} 

} 

什麼，我做錯了什麼？

您必須將窗體傳遞給視圖。將此添加到您的控制器。

return $this->render(
    'Bundle:Controller:view.html.twig', 
     array(
      'filterForm' => $filterForm->createView() 
    ) 
);
