创建一个表单类型，其中包含两个单独的值，可以使用symfony 4多次添加

php bin/console make:form

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\IntegerType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ExampleFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('value1', TextType::class)
            ->add('value2', IntegerType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            // 设置表单数据类
            'data_class' => ExampleFormData::class,
        ]);
    }
}

namespace App\Controller;

use App\Form\ExampleFormType;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class ExampleController extends AbstractController
{
    /**
     * @Route("/example", name="example")
     */
    public function exampleAction(Request $request): Response
    {
        $form = $this->createForm(ExampleFormType::class);

        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            // 处理表单提交
            $data = $form->getData();
            // 对表单数据进行处理或保存到数据库等操作

            // 重定向到其他页面或返回响应
            return $this->redirectToRoute('success');
        }

        return $this->render('example.html.twig', [
            'form' => $form->createView(),
        ]);
    }
}

{# example.html.twig #}

<form method="post" action="{{ path('example') }}">
    {{ form_widget(form) }}
    <button type="submit">提交</button>
</form>
