symfony - 如何在 symfony 中为奏鸣曲块服务添加中继器（克隆）字段

问题描述

我正在使用 CMS 选项处理 symfony(4.2) 项目。所以我决定使用 Sonata bundles 来实现类似 WP 的 CMS。目前我已经安装并使用了 SonataAdminBundle、SonataMediaBundle、SonataBlockBundle...等。我还为页面块创建了带有基本表单字段的自定义服务，它对我来说很好用。现在我想创建一个带有重复字段的表单，如克隆系统

我创建了一个名为 CloneType 的新表单类型并自定义了表单模板。还在块服务文件中添加了 CloneType 字段，现在表单如下图所示

在浏览器中检查时，我的输入看起来像这样

 <input type="text" id="s9fdc9db89c_settings_cxi_different_title" name="s9fdc9db89c[settings][cxi_different][title_1]" class=" form-control" value="test">
 <input type="text" id="s9fdc9db89c_settings_cxi_different_title" name="s9fdc9db89c[settings][cxi_different][title_2]" class=" form-control" value="test">

namespace App\Form\Type;

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

{
    public function getParent()
    {
        return FormType::class;
    }
}

    <div class="clone-wrapper">

                    var id = this.id || "";
                    var match = id.match(regex) || [];
                    if (match.length == 3) {
                        this.id = match[1] + (cloneIndex);
                    }

src/Application/Sonata/BlockBundle/Block/CxiDifferentBlockService.php

<?php 
namespace App\Application\Sonata\BlockBundle\Block;

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\FormType;
use Sonata\Form\Type\ImmutableArrayType;
use Sonata\Form\Validator\ErrorElement;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\BlockBundle\Meta\Metadata;

use Sonata\BlockBundle\Model\BlockInterface;
use Sonata\BlockBundle\Block\Service\AbstractBlockService;

use App\Form\Type\CloneType;
use Sonata\AdminBundle\Admin\AdminInterface;
class CxiDifferentBlockService extends AbstractBlockService
{
 public function buildEditForm(FormMapper $formMapper, BlockInterface $block)
 {
    $formMapper
        ->add('settings', ImmutableArrayType::class, [
            'keys' => [
                ['title', TextType::class, [
                    'label' => 'Title (H2)',
                    'required' => false,
                ]],
                [$this->getCloneBuilder($formMapper), null, []],                   
            ],
        ])
    ;        
  }
  protected function getCloneBuilder(FormMapper $formMapper)
  {
     return $formMapper->create('cxi_different', CloneType::class, ['required' => false,'by_reference' => false,'allow_extra_fields'=>true])
         ->add('title', TextType::class,['required' => false, 'allow_extra_fields'=>true, 'by_reference' => false])
    ;
  }
}

我想更新数据库中的克隆字段值。但它不起作用。我在提交表单时检查了数据。奏鸣曲形式未在 post 数组中添加克隆字段。帖子数组看起来像下面的实际结果

实际结果 ：

Array(
 [title] => test
 [cxi_different] => Array
    (
        [title_1] => test
    )
)

预期结果 ：

Array(
 [title] => test
 [cxi_different] => Array
    (
        [title_1] => test
        [title_2] => test
    )
)

提前致谢！

解决方案

我已经使用CollectionType来实现这一点，并且我已经按照以下步骤来实现这一点

第 1 步： 我在 src/Form/CloneFormType.php 中添加了新的 FormType

<?php

namespace App\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Sonata\AdminBundle\Form\Type\CollectionType;

final class CloneFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('title_1', TextType::class)
            ->add('title_2', TextType::class)
            ;
    }
}

第 2 步： 现在 BlockService 应该是这样的

<?php 
namespace App\Application\Sonata\BlockBundle\Block;

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\FormType;
use Sonata\Form\Type\ImmutableArrayType;
use Sonata\Form\Validator\ErrorElement;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\BlockBundle\Meta\Metadata;
use Sonata\BlockBundle\Block\BlockContextInterface;
use Sonata\BlockBundle\Model\BlockInterface;
use Sonata\BlockBundle\Block\Service\AbstractBlockService;
use App\Application\Sonata\PageBundle\Entity\Block;
use App\Form\CloneFormType;
use Sonata\AdminBundle\Admin\AdminInterface;
class CxiDifferentBlockService extends AbstractBlockService
{
 public function buildEditForm(FormMapper $formMapper, BlockInterface $block)
 {
    $formMapper
        ->add('settings', ImmutableArrayType::class, [
            'keys' => [
                ['title', TextType::class, [
                    'label' => 'Title (H2)',
                    'required' => false,
                ]],
                ['cxi_different', CollectionType::class, [
                    'required' => false,
                    'allow_add' => true,
                    'allow_delete' => true,
                    'prototype' => true,
                    'by_reference' => false,
                    'allow_extra_fields' => true,
                    'entry_type' => CloneFormType::class,
                ]],                  
            ],
        ])
    ;        
  }
}

第 3 步： 您可以删除以下文件。使用此CollectionType时不需要

  1. src/Form/Type/CloneType.php
  2. 模板/sonataadmin/forms/clone.twig.html
  3. 也不要忘记从 src/Application/Sonata/BlockBundle/Block/CxiDifferentBlockService.php 中删除这一use App\Form\Type\CloneType;行use App\Form\CloneFormType;（
