Symfony表单子表单类型的property_path

Question

我明白，如果我放

        ->add('visitor.name', TextType::class, [
            'property_path' => 'vistorName'
        ])

这与<input name="vistorName"相同

如何为子窗体执行类似操作，将所有子字段作为父字段名称，而不将其作为子数组放入。

        $builder->add('customer', CustomerType::class);

客户类型

    $builder
        ->add('name', TextType::class)
        ->add('email', EmailType::class)
        ->add('phone', PhoneNumberType::class, [
            'default_region' => 'GB', // TODO GLOBAL release
            'format' => PhoneNumberFormat::NATIONAL
        ]);

上面的表格应该生成<input name="name"... <input name="email"...而不是跟随<input name="customer[name]"...

我怎样才能做到这一点？

以下是完整的代码示例

// Cart model
class Cart {

    protected $productName;

    /** @var Customer */
    protected $customer;
}

// Customer model
Class Customer {

    protected $name;

    protected $email;

    protected $phone;
}


//CustomerType form
$builder
    ->add('name', TextType::class)
    ->add('email', EmailType::class)
    ->add('phone', PhoneNumberType::class, [
        'default_region' => 'GB', // TODO GLOBAL release
        'format' => PhoneNumberFormat::NATIONAL
    ]);


// main parent form

class MainFormType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('productName', TextType::class)
            ->add('customer', CustomerType::class); // need property_path for this, so all the inner fields can be used as parent
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Cart::class,
            'required' => false
        ]);
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix()
    {
        return 'cart';
    }
}

Answer 1

它的工作原理相反：

场景：

VisitorEntity：

• TypeOfVisitorEntity
• CustomerEntity

现在您要更新VisitorEntity customer.name：

class MainFormType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('productName', TextType::class)
            ->add('customerName', TextType::class, ['property_path'=>'customer.name'])
            ->add('customerEmail', TextType::class, ['property_path'=>'customer.email'])
            ->add('customerPhone', TextType::class, ['property_path'=>'customer.phone'])
    ;
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Cart::class,
            'required' => false
        ]);
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix()
    {
        return 'cart';
    }
}

property_path

https://symfony.com/doc/3.4/reference/forms/types/form.html#property-path

type：any default：字段的名称

默认情况下，Fields显示表单域对象的属性值。提交表单时，将提交的值写回对象。

如果要覆盖字段读取和写入的属性，可以设置property_path选项。其默认值是字段的名称。

如果希望在读取或写入对象时忽略该字段，可以将property_path选项设置为false，但不建议使用property_path，则应使用映射选项。
