];

配置

添加插件配置

# config/packages/dynamic_form.yaml

dynamic_form:
    recursive: true # Browse config folders recursively
    config_paths: # Files configuration paths
        - '%kernel.project_dir%/config/dynamic_form'
when@prod:
    framework:
        cache:
            pools:
                dynamic_form_pool_cache:
                    adapter: cache.adapter.redis
    dynamic_form:
        cache_pool: dynamic_form_pool_cache # Use cache 'dynamic_form_pool_cache' to store parsed configuration (recommended in production)

表单配置示例

                ],
            ],
        ],
    ],
];

创建表单

<?php

declare(strict_types=1);

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Form\FormFactoryInterface;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Wemxo\DynamicFormBundle\Form\DynamicType;
use Wemxo\DynamicFormBundle\Utils\Helper\DynamicFormHelper;

class AppController extends AbstractController
{
    #[Route(name: 'app_home')]
    public function home(FormFactoryInterface $formFactory): Response
    {
        $user = $this->getUser();
        $countryLabel = $user->getCountry()->getLabel();
        $form = $formFactory->create(DynamicType::class, null, [
            'dynamic_key' => DynamicFormHelper::configKey('address', $countryLabel),
        ]);

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

带有块前缀的表单创建

<?php

declare(strict_types=1);

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Form\FormFactoryInterface;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Wemxo\DynamicFormBundle\Form\DynamicType;
use Wemxo\DynamicFormBundle\Utils\Helper\DynamicFormHelper;

class AppController extends AbstractController
{
    #[Route(name: 'app_home')]
    public function home(FormFactoryInterface $formFactory): Response
    {
        $user = $this->getUser();
        $countryLabel = $user->getCountry()->getLabel();
        $form = $formFactory->createNamed('my_custom_prefix', DynamicType::class, null, [
            'dynamic_key' => DynamicFormHelper::configKey('address', $countryLabel),
        ]);

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

使用表单事件订阅者

1 - 通过实现接口 Wemxo\DynamicFormBundle\EventSubscriber\DynamicFormEventSubscriber 创建一个类。

1.1 - 实现 getName 函数。

1.2 - 实现 getSubscribedEvents 函数。

<?php

declare(strict_types=1);

namespace App\Form;

use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Wemxo\DynamicFormBundle\EventSubscriber\DynamicFormEventSubscriber;

class AddressFormEventSubscriber implements DynamicFormEventSubscriber
{

    public function getName(): string
    {
        return 'address_event_subscriber';
    }

    public static function getSubscribedEvents(): array
    {
        return [
            FormEvents::PRE_SET_DATA => 'onPreSetData',
        ];
    }
    
    public function onPreSetData(FormEvent $event): void
    {
        // do something.
    }
}

1.3 - 更新表单配置

france:
    form:
        subscribers:
            - address_event_subscriber # The value returned from the getName function.
        fields: []
