Sylius: require address in registration - php

Question

I want customers to fill in their address right at the registration, not at the checkout of an first order.
I see, that Sylius\Component\Core\Model\Customer has attributes $defaultAddress: AddressInterface and $addresses: Collection|AddressInterface[].
This is where I stucked. If there would be singular ($address: AddressInterface) I would know, I should extend form type and add there address field.
But how to require user to fill in exactly one address into this collection?
I tried this:
My form type used for registration (where parent is Sylius\Bundle\CoreBundle\Form\Type\Customer\CustomerRegistrationType):
->add(
'addresses',
CollectionType::class,
[
'entry_type' => WholesaleCustomerAddressType::class
]
)
Where WholesaleCustomerAddressType is child of Sylius\Bundle\AddressingBundle\Form\Type\AddressType and remove some fields (name, phone, etc.)
How it works:
The address field at the registration page is not rendered (only empty div is). When I dump form.adresses I see it has no children.
It renders only this:
<div data-form-type="collection" id="wholesale_customer_registration_addresses" class="form-control controls collection-widget" placeholder="Addresses"><div data-form-collection="list"></div></div>
How it should work:
The form should render fields for exactly one address. After click submit, the user should be registred, should has exactly one address and this address should be $defaultAddress also.
I see the problem is in the thing, that at the time of registration the collection of addresses is empty. How to add in Sylius a first record?

Answer 1

Might be a little late but if someone else stumbles on your question, this is how I solved it...
As you pointed out yourself there is an attribute $defaultAddress: AddressInterface. Simply add this field to your custom form or in my case the form extension and assign the appropriate type. I used the Sylius\Bundle\AddressingBundle\Form\Type\AddressType and that's it.
My Form extension:
<?php
namespace App\Form\Extension;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\AbstractTypeExtension;
use Sylius\Bundle\AddressingBundle\Form\Type\AddressType;
use Sylius\Bundle\CoreBundle\Form\Type\Customer\CustomerRegistrationType;
final class CustomerRegistrationTypeExtension extends AbstractTypeExtension
{
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options): void
{
// Adding the defaultAddress as extra fields to the form
$builder->add('defaultAddress', AddressType::class, [
'label' => 'sylius.form.customer.default_address',
]);
}
/**
* {#inheritdoc}
*/
public function getExtendedTypes(): array
{
return [CustomerRegistrationType::class];
}
}
Don't forget to add the extension as a service:
app.form.extension.type.customer_registration:
class: App\Form\Extension\CustomerRegistrationTypeExtension
tags:
- { name: form.type_extension, extended_type: Sylius\Bundle\CustomerBundle\Form\Type\CustomerRegistrationType }
And don't forget to render the new field in tour template:
{{ form_row(form.defaultAddress) }}
