use Symfony\Component\Form\Extension\Core\Type\DateType;

// ...

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        // ...
        ->add('date', DateType::class, [
            'label' => '选择日期',
            'widget' => 'single_text',
            'format' => 'yyyy-MM-dd',
            'attr' => ['class' => 'datepicker'],
        ])
        // ...
    ;
}

use AppBundle\Entity\YourEntity;
use AppBundle\Form\YourFormType;

// ...

public function yourAction(Request $request)
{
    $entity = new YourEntity();
    $form = $this->createForm(YourFormType::class, $entity);

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        // 处理表单提交
        $entityManager = $this->getDoctrine()->getManager();
        $entityManager->persist($entity);
        $entityManager->flush();

        // 重定向或显示成功消息
    }

    // 渲染表单视图
    return $this->render('your_template.html.twig', [
        'form' => $form->createView(),
    ]);
}
