Question

我的Symfony表单使用BirthdayType字段。它的默认行为是为月，日和年添加三个单独的下拉菜单。我按照here所述添加了文本小部件选项，以便具有三个单独的文本输入字段。我的问题是：如何为每个输入字段生成标签？

生成的HTML是：

   <div id="user_birthDate">
       <input type="text" id="user_birthDate_month" name="user[birthDate][month]" required="required">
       <input type="text" id="user_birthDate_day" name="user[birthDate][day]" required="required">
       <input type="text" id="user_birthDate_year" name="user[birthDate][year]" required="required">
   </div>

FormBuilder（节选）：

 public function buildForm(FormBuilderInterface $builder, array $options): void
 {
     $builder
        ->add('birthDate', BirthdayType::class, ['widget' => 'text'])
        ->add('next', SubmitType::class);
  }

Answer 1

您可以像使用“小部件”一样在选项中添加标签

public function buildForm(FormBuilderInterface $builder, array $options): void
 {
 $builder
    ->add('birthDate', BirthdayType::class, [
         'widget' => 'text',
         'label' => 'Birthday label that you want to show',
        ])
    ->add('next', SubmitType::class);
 }

另请参见https://symfony.com/doc/current/forms.html#field-type-options

您应该制作一个自定义树枝：

{#birthdate.html.twig !#}

{% block birthday_widget %}
    {% spaceless %}
     <label> month </label>
     <input type="text" id="user_birthDate_month" name="user[birthDate][month]" required="required">

     <label> day </label>
     <input type="text" id="user_birthDate_day" name="user[birthDate][day]" required="required">

     <label> year </label>
     <input type="text" id="user_birthDate_year" name="user[birthDate][year]" required="required">

    {% endspaceless %}
{% endblock %}

并将此行添加到config.yml中：

# app/config/config.yml
twig:
    form_themes:
        - 'form/birdhdate.html.twig'
