Symfony 3 - 子表单和元素名称

Question

我想用这样的组合模式创建表单： https://symfony.com/doc/current/form/inherit_data_option.html

我使用 Symfony 3。

它正在运行。我让每个元素都像单个对象并添加这个。

但最后我的表单元素名称变成了

form[subform][element]

如何在名称属性中制作没有子表单的平面结构？

use AppBundle\Base\Form\NickType;
use AppBundle\Base\Form\MailType;
use AppBundle\Base\Form\PassType;
use AppBundle\Base\Form\UserType;


class RegisterType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('nick', NickType::class)
            ->add('mail', MailType::class)
            ->add('password', PassType::class)
            ->add('repeat_password', PassType::class)
(etc...)

和单元素

class NickType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('nick', TextType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'inherit_data' => true
        ));
    }

}

Answer 1

如果 NickType 仅继承 TextType，则无需定义它。您可以删除 NickType、MailType 等

你可以这样做：

class RegisterType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('nick', TextType::class)
        ;
(etc...)

如果你想重用一个表单域，你必须创建一个 Custom Form Field Type:

class NickType extends AbstractType
{
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            //...
        ));
    }

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

您可以从元素名称中删除 form[]，但实际上并不推荐删除它，因为当您读取填充表单数据的请求时，您可以通过表单名称来识别表单。 (via)

You can set the name of the root form to empty, then your field name will be just form. Do so via

// the first argument to createNamedBuilder() is the name
$form = $this->get('form.factory')->createNamedBuilder(null, 'form', $defaultData)
    ->add('from', 'date', array(
        'required' => false,
        'widget' => 'single_text',
        'format' => 'dd.MM.yyyy'
    ));
