我收到错误:
Call to undefined method Symfony\Component\Form\FormBuilder::createView()
以下代码
public function searchAction(Request $request, $type) {
$filters = new Filters();
$form = $this->createFormBuilder($filters)
->setAction($this->generateUrl('project_search'))
->add('name', 'text');
if($type == 'extra') {
$form->add('job', 'text');
}
$form->add('send', 'submit', array('label' => "Envoyer"))
->getForm();
return $this->render('Bundle:Controller:search.html.twig', array(
'form' => $form->createView(),
));
}
我相信这是因为我添加了新的输入$form->add('job', 'text');
。我该如何解决这个问题?
答案 0 :(得分:5)
您需要引用Form
个实例,而不是FormBuilder
。您已经使用了返回所需参考的getForm()
方法,但您并未将其分配到任何地方。
$filters = new Filters();
$formBuilder = $this->createFormBuilder($filters)
->setAction($this->generateUrl('project_search'))
->add('name', 'text');
if($type == 'extra') {
$formBuilder->add('job', 'text');
}
$formBuilder->add('send', 'submit', array('label' => "Envoyer"));
$form = $formBuilder->getForm();
return $this->render('Bundle:Controller:search.html.twig', array(
'form' => $form->createView(),
));
