使用Symfony 3更新數據

Question

我有簡單的編輯表單，用戶必須填寫必填字段。問題是沒有顯示必填字段的驗證，並且字段或數據也不會更改。

UPDATE我的var_dump的$form->isSubmitted()，它顯示bool(false)

這裏是我的控制器：

public function editAction(Request $request, $id) { 

    $company = $this->getDoctrine() 
     ->getRepository('SwipeBundle:Company') 
     ->find($id); 

    if(!$company) { 
     throw $this->createNotFoundException(
      'No Company found for id '.$id 
     ); 
    } 

    $form = $this->createForm(CompanyType::class, $company, array(
     'action'=>$this->generateUrl('swipe_backend_company_edit', array('id'=>$company->getId())), 
     'method'=>'PUT' 
    ));  

    if ($request->getMethod() == "POST") { 

      if ($form->isSubmitted()) { 

       // $em->persist($company); 
       // $em->flush(); 
       echo "Update"; 
      } 
     } 


    return $this->render('Backend/Company/edit.html.twig', array(
     'form'=>$form->createView(), 
     'company'=>$company 
    )); 
} 

這是我的樹枝模板：

{% extends '::Backend/base.html.twig' %} 
{% block body %} 

    <!-- Section --> 
    <section class="sections"> 

     <!-- Side Bar --> 
     {% include '::Backend/side_menu_bar.html.twig' %}

只有一個編輯/更新動作記錄

public function editAction($id) { 

    $em = $this->getDoctrine()->getManager();   
    $company = $em 
     ->getRepository('SwipeBundle:Company') 
     ->find($id); 

    if(!$company) { 
     throw $this->createNotFoundException(
      'No Company found for id '.$id 
     ); 
    } 

    $form = $this->createForm(CompanyType::class, $company, array(
     'action'=>$this->generateUrl('swipe_backend_company_update', array('id'=>$company->getId())), 
     'method'=>'PUT' 
    )); 

    if ($request->getMethod() == "POST") { 

     if ($form->isValid()) { 

      $em->persist($company); 
      $em->flush(); 
     } 
    } 

    return $this->render('Backend/Company/edit.html.twig', array(
     'form'=>$form->createView(), 
     'company'=>$company 
    )); 
} 

，改變在樹枝一樣一編輯操作的形式作用

確保這是對你有用。
