我在页面上看到了一个实体的多个字段，我希望每个字段都可以通过 ajax 进行编辑，一次一个。为此，我想出了为所有领域构建一个独特的控制器的想法，但我无法让它工作，我不知道这是否是我尝试做的正确解决方案。我的页面显示字段：

<div>
 <form class="ajax" action="{{ path('ajax_setSocial', { 'id': entity.id }) }}" method="post" {{ form_enctype(form) }}>
  <div class="editor">
        {{ form_errors(form) }}
        <div class="editLabel pls lti">{{ form_label(form.ragSocial) }}</div>
        <div class="editField"> 
            <div class="ptm">
                {{ form_widget(form.ragSocial) }} {{ form_errors(form.ragSocial) }}
            </div>     
            {{ form_widget(form._token) }}
            <div class="mtm">
                <button class="btn btn-primary disabled save" type="submit" disabled>Save</button>
                <button class="btn ann">Cancel</button>
            </div>
        </div>
  </div>
  </form>
 </div>
 <div>
  <form class="ajax" action="{{ path('ajax_setSocial', { 'id': entity.id }) }}" method="post" {{ form_enctype(form) }}>
  <div class="editor">
        {{ form_errors(form) }}
        <div class="editLabel pls lti">{{ form_label(form.pIva) }}</div>
        <div class="editField"> 
            <div class="ptm">
                {{ form_widget(form.pIva) }} {{ form_errors(form.pIva) }}
            </div>     
            {{ form_widget(form._token) }}
            <div class="mtm">
                <button class="btn btn-primary disabled save" type="submit" disabled>Save</button>
                <button class="btn ann">Cancel</button>
            </div>
        </div>
  </div>
  </form>
 </div>

在我的控制器中：

public function setSocialAction(Request $request, $id)
{
    $em = $this->getDoctrine()->getManager();
    $entity = $em->getRepository('MyBusinessBundle:Anagrafica')->find($id);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find Anagrafic entity.');
    }
    $field = $request->get('field');
    $class = $field.'Type()';
    $form = $this->createForm(new $class, $entity);
    $form->bind($request);

    if ($form->isValid()) {
        $em->persist($entity);
        $em->flush();

        $response = new Response();
        $output = array('success' => true);
        $response->headers->set('Content-Type', 'application/json');
        $response->setContent(json_encode($output));

        return $response;
    }

$class = $field.'Type()';
$form = $this->createForm(new $class, $entity); 使用这些代码行，我尝试创建生成表单字段的动态类，但由于它被转换为字符串并且我得到的错误是：

Fatal error: Class 'ragSocialType()' not found

但上课是！并且也被称为顶级文件..我希望我解释一下，我接受任何建议以遵循更好的方法！

$class = $field.'Type'; //remove the ()
$form = this->createForm(new $class, $entity);
