首先，我想澄清一下，我并没有(甚至)为我的表单使用 Entities/Doctrine。我正在使用网络服务来添加/编辑数据库的数据字段

我正在开展一个项目，我需要编辑具有多个地址的公司信息。 第一个地址始终是物理地址，因此我在与公司数据相同的循环中获取它。

然而，第二个(和第三个，或第四个，如果存在的话)地址被放置在一个单独的数据库条目中。 我可以用一种形式编辑公司数据和公司地址(物理地址)(因为数据都在一组中)因此我只需要一种形式，而不必使用循环地址。

现在我想编辑第二个地址。我正在遍历 twig 中的地址并打印出该公司的所有其他地址。 据我所知，Symfony 不允许相同形式的多个实例，因为这会干扰 ID 等。

问题是我应该如何只为特定地址呈现表单。我想通过单击按钮进行编辑(如果不编辑，则使用 bootstrap collapse 隐藏表单)

我的代码是这样的:

Controller :

public function editcompany(Request $request, $klantnr)
{

    [...]

    $result = [
        'gegevens' => [],
        'addresses' => [],
    ];

    foreach ($company as $row) {
        $dataFields = [
            [...] // The data fields of the company (including the physical address)
        ];
        foreach ($dataFields as $dataField) {
            if (empty($result['gegevens'][$dataField])) {
                $result['gegevens'][$dataField] = $row[$dataField];
            }
        }
        if($row['AdrGid'] != $result['gegevens']['AdrGid']) {
            $result['addresses'][$row['AdrGid']] = [
                [...] // The data fields for the other addresses 
            ];
        }
    }

    // The form creation of the company data form
    $form = $this->createForm(EditcompanyForm::class);

    // The form of the other addresses
    $form_adres = $this->createForm(EditcompanyAdresForm::class, array(
        [...]
    ));
    $form->handleRequest($request);
    $form_adres->handleRequest($request);


    if($form->isSubmitted() && $form->isValid()) {
        [...] // Handling the submitted data for the company data
    }

    // GEKOPPELDE ADRESSEN company
    if($form_adres->isSubmitted() && $form_adres->isValid()) {

        [...]

        $data = array(
            [...] // Setting the data for the other addresses
        );

        [...]

        // Passing the data and other options to the webservices
        $this->get('http')->companyRequest($data, $admincode, $service, $token);

        $request->getSession()
            ->getFlashBag()
            ->add('success', 'Linked address successfully edited');

        return $this->redirect($request->getUri());
    }

    return $this->render('pages/company/edit.html.twig', array(
        'client' => $result,
        'form_company' => $form->createView(),
        'form_company_adres' => $form_adres->createView()
    ));
 }

表单生成器(抽象类型):

class EditcompanyAdresForm extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $factuuradres = $options['NawFactuurAdres'];
        $lands = $options['lands'];

        $data = array();
        $builder
            [...] // Add the necessary fields
    }
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            [...] // setting defaults here
        ));
    }
    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix()
    {
        return 'appbundle_form_editcompanyadresform';
    }
}

Twig 模板(显示地址:

{% for address in client.addresses %}
    <div class="right-cont-grey">
        [...] // showing addresses
    </div>
{% endfor %}

Twig模板(编辑形式):

{% for address in client.addresses %}
    {{ form_start(form_company_adres, {'  method': 'POST'}) }}
    {{ form_row(form_company_adres._token) }}
        <section class="collapse" id="adres_plus">
            <div id="adres" class="new-adres collapse right-cont-grey">
                <div class="col-sm-12">
                    [...] // Form_widgets with values from database
            </div>
        </section>
    {{ form_end(form_company_adres) }}
{% endfor %}

简而言之:

如何在不干扰的情况下为每个地址使用地址表？也许在循环内的 Twig 文件中创建 View (渲染)？ 我的表单已预先填入数据库中的数据，因此我可以对其进行编辑。

最佳答案

修改了关于我们在聊天中讨论的内容的答案:

正如我在评论中所写，我确定您只需要设置一个 collection field .然后，整个复杂性基本上消失了。

一个非常简单的例子是:

Controller :

public function editCompanyAction(Request $request)
{
    // get the data anyway you see fit and produce a model (this could also be a dedicated DTO)
    $company = $this->getInput();

    // create the form
    $form = $this
        ->createForm(CompanyWithAddressesType::class, $company)
        ->handleRequest($request)
    ;

    // handle submission
    if ($form->isSubmitted() && $form->isValid()) {
        dump($form->getData()); // === $company
    }

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

表格

这里的重要部分是您添加的字段的名称与作为数据提供的数组中的键匹配!

class CompanyWithAddressesType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // combine the company with a collection of addresses:
        $builder
            ->add('gegevens', CompanyType::class)
            ->add('addresses', CollectionType::class, [
                'entry_type' => AddressType::class,
            ])
        ;
    }
}

class CompanyType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // all the fields that are *extra* for companies, address fields are inherited
        // because this type extends the address type (see below getParent)
        $builder
            ->add('NawWebsite', TextType::class)
            ->add('email1', TextType::class)
            ->add('AdrNaam1', TextType::class)
        ;
    }

    /**
     * @return @inheritdoc
     */
    public function getParent()
    {
        return AddressType::class;
    }
}

class AddressType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // all the fields that define an address
        $builder
            ->add('AdrStraat', TextType::class)
            ->add('AdrHuisnummer', TextType::class)
            ->add('AdrPostcode', TextType::class)
            ->add('NawFactuurAdres', CheckboxType::class)
        ;
    }
}

Twig :

简单的输出表格。任何form customization适用

{{ form_start(form) }}
    <div>
        <h4>Company</h4>
        {{ form_row(form.gegevens.NawWebsite) }}
        {{ form_row(form.gegevens.email1) }}
        {{ form_row(form.gegevens.AdrNaam1) }}
    </div>

    <div>
        <h4>Main address</h4>
        {{ form_rest(form.gegevens) }}
    </div>

    <div>
        <h4>Extra addresses</h4>
        {% for address in form.addresses %}
            {{ form_errors(address) }}
            {{ form_widget(address) }}
        {% endfor %}
    </div>

    <button>Submit</button>
{{ form_end(form) }}
