Question

我不知道为什么我无法从控制器变量中获取表单上的值。

我的控制器：

public function indexAction(Request $request,$id){
    $ac = new Usersacademi();
    $form = $this->createForm(UsersacademiType::class,$ac,array('id'=>$id));
    $form->handleRequest($request);

    if($form->isValid()){
        $ac->setIdacademicprogram($form->get("idacademicprogram")->getData());
        $ac->setIduser($form->get("iduser")->getData());
        $em = $this->getDoctrine()->getManager();
        $em->persist($ac);
        $flush = $em->flush();
    }
    else{
    }


    return $this->render("AppBundle:admin:apteacher.html.twig", array(
        "form" => $form->createView()
    ));
}

我的表格：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('idacademicprogram', EntityType::class, array(
            "required"=>"required",
            'class' => 'AppBundle:Academicprogram',
            'choice_label' => 'name'
        ))
        ->add('iduser', NumberType::class, array("required"=>"required",
            "data" =>$options["id"],
            "attr"=>array(
            "class" => "form-iduser form-control"
        )));
}

我收到此错误：

选项＆＃34; id＆＃34;不存在。定义的选项是：＆＃34; action＆＃34;，＆＃34; allow_extra_fields＆＃34;，＆＃34; attr＆＃34;，＆＃34; auto_initialize＆＃34;，＆＃34; block_name＆＃34;，＆＃34; by_reference＆＃34;，＆＃34;复合＆＃34;，＆＃34;约束＆＃34;，＆＃34; csrf_field_name＆＃34;，＆＃34; csrf_message＆＃34;，＆＃34; csrf_protection＆＃34;，＆＃34; csrf_token_id＆＃34;，＆＃34; csrf_token_manager＆＃34;，＆＃34;数据＆＃34;，＆＃34; data_class＆＃34;，＆＃34;禁用＆＃34;，＆＃34; empty_data＆＃34;，＆＃34; error_bubbling＆＃34;，＆＃34; error_mapping＆＃34;，＆＃34; extra_fields_message＆＃34;，＆＃34; inherit_data＆＃34;，＆＃34; invalid_message＆＃34;，＆＃34; invalid_message_parameters＆＃34;，＆＃34;标签＆＃34;，＆＃34; label_attr＆＃34;，＆＃34; label_format＆＃34;，＆＃34;映射＆＃34;，＆＃34;方法＆＃34;，＆＃34; post_max_size_message＆＃34;，＆＃34; property_path＆＃34;，＆＃34; required＆＃34;，＆＃34; translation_domain＆＃34;，＆＃34; trim＆＃34;，＆＃34; upload_max_size_message＆＃34;，＆＃34; validation_groups＆＃34;

在setDefaultOptions中声明一个空数组。

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'YourEntity',
        'id' => array(),
    ));
}

从控制器获取值以形成symfony 3
