update customer attribute in frontend account profile form - frontend

Question

I'm learning Shopware and I got to something I can't figure out how to solve.
I'm writing a test plugin that adds an attribute to the customer. I've added the correspondent field to the Registration form and it saves its value to the db automatically, like I read somewhere in the docs.
Now I wanted to let the attribute be editable in the account profile page, after the password field. I managed to put the input there, and even show the value from the db. But when I change the value and save, the value its not updated. I don't know if it is just a matter of getting the field name right, or do I need to override something else. Or is it just not possible? Any help on how to achieve this would be greatly appreciated.
Relevant code below:
plugin bootstrap
public function install(InstallContext $context)
{
$service = $this->container->get('shopware_attribute.crud_service');
$service->update('s_user_attributes', 'test_field', 'string');
$metaDataCache = Shopware()->Models()->getConfiguration()->getMetadataCacheImpl();
$metaDataCache->deleteAll();
Shopware()->Models()->generateAttributeModels(['s_user_attributes']);
return true;
}
register/personal_fieldset.tpl
{extends file="parent:frontend/register/personal_fieldset.tpl"}
{block name='frontend_register_personal_fieldset_password_description'}
{$smarty.block.parent}
<div class="register--test-field">
<input autocomplete="section-personal test-field"
name="register[personal][attribute][testField]"
type="text"
placeholder="Test Field"
id="testfield"
value="{$form_data.attribute.testField|escape}"
class="register--field{if $errorFlags.testField} has--error{/if}"
/>
</div>
{/block}
account/profile.tpl
{extends file="parent:frontend/account/profile.tpl"}
{block name='frontend_account_profile_profile_required_info'}
<div class="profile--test-field">
<input autocomplete="section-personal test-field"
name="profile[attribute][testfield]"
type="text"
placeholder="Test Field"
id="testfield"
value="{$sUserData.additional.user.test_field|escape}"
class="profile--field{if $errorFlags.testField} has--error{/if}"
/>
</div>
{$smarty.block.parent}
{/block}

The form type that it's used on registration isn't the same you have on profile.
If you check \Shopware\Bundle\AccountBundle\Form\Account\PersonalFormType::buildForm, you can see
$builder->add('attribute', AttributeFormType::class, [
'data_class' => CustomerAttribute::class
]);
That means the attributes are included on form and they will be persisted. That's why you can save the value on registration form.
On profile you have \Shopware\Bundle\AccountBundle\Form\Account\ProfileUpdateFormType. And here the attribute isn't added to form builder.
How to extend the ProfileUpdateFormType?
Subscribe Shopware_Form_Builder on Bootstrap (or on a specific Subscriber class)
$this->subscribeEvent('Shopware_Form_Builder', 'onFormBuild');
Create the method onFormBuild to add your logic
public function onFormBuild(\Enlight_Event_EventArgs $event) {
if ($event->getReference() !== \Shopware\Bundle\AccountBundle\Form\Account\ProfileUpdateFormType::class) {
return;
}
$builder = $event->getBuilder();
$builder->add('attribute', AttributeFormType::class, [
'data_class' => CustomerAttribute::class
]);
}
With this approach all attributes are available on your profile form.
Other possibility you have is using the 'additional' property instead of 'attribute' and then subscribe a controller event or hook a controller action to handle your custom data.
