Php 如何在symfony表单中禁用必填字段？

我有一个需要zipcode的地址表单类型。这是密码

class AddressType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('poBox', TextType::class, ['required' => false])
            ->add('roomNumber', TextType::class, ['required' => false])
            ->add('building', TextType::class, ['required' => false])
            ->add('street', TextType::class, ['required' => false])
            ->add('street2', TextType::class, ['required' => false])
            ->add('country', null, [
                "invalid_message" => "Country is required."
            ])
            ->add('state', null, [
                "invalid_message" => "State is required."
            ])
            ->add('city', null, [
                "invalid_message" => "City is required."
            ])
            ->add('zipCode', TextType::class, [
                "invalid_message" => "Postal Code given is not a valid value.",
                "required" => true,
                "constraints" => [
                    new NotBlank(["message" => "Postal Code is required"]),
                    new Length(["min" => 5, "max" => 5, "exactMessage" => "Postal Code must be a 5-digit code" ]),
                    new Regex(["pattern" => "/^[0-9]+$/", "message" => "Postal code must be numbers only"])
                ]
            ]);
    }

正如您所看到的，我只需要zipcode。我有另一种形式，我称之为人型。这个表单类型，我继承了AddressType类。但正如您所看到的，我禁用了必填字段（false）

每次提交表单时，我都会收到表单错误

需要邮政编码

。我已经为AddressType禁用了person类型表单中的必填字段。我无法将邮政编码的必填字段更改为false，因为其他表单类型（如CompanyType）需要邮政编码。有人在如何将必填字段更改为false时遇到这种问题吗？

您只需添加此代码即可

$builder->get('address')->setRequired(false);

$builder->get('address')->setRequired(false);
