Question

我试图在索引页面上显示一组单选按钮（男性或女性）。在我的表单中，我构建了这样的表单：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
    ->add('gender', ChoiceType::class, array(
        'choices'  => array(
            'Male' => 1,
            'Female' => 2,
        )));
}

然后在Controller中：

public function indexAction(Request $request)
{
    $participantEntry = new Participants();

    $form = $this->createForm(ParticipantsType::class, $participantEntry,[
        'action' => $request->getUri()
    ]);

    $form->handleRequest($request);

    return $this->render('SurveyBundle:Page:index.html.twig',
        ['form' => $form->createView()]);

}

但是，我不确定如何在我的Twig文件中实际显示为RadioButtons，这是我尝试过的：

{% for g in form.gender %}
    {{ g.value }}
{%  endfor %}

顺便说一句：我的实体中的$性别是一个int

哪个不起作用，有谁知道我做错了什么？

将->add('gender', ChoiceType::class, array( 'choices' => array( 'Male' => 1, 'Female' => 2, ), 'expanded' => true, 'multiple' => false );更改为构建器，如下所示

'expanded' => true

'multiple' => false和form_widget(form.gender)的组合将生成单选按钮，然后在树枝中，只需使用

<telerik:RadGrid RenderMode="Lightweight" id="RadGrid1" runat="server">
    <ClientSettings>
        <Resizing AllowColumnResize="true" ResizeGridOnColumnResize="true" AllowResizeToFit="true" />
    </ClientSettings>
</telerik:RadGrid>

将返回的数组显示为单选按钮
