oroCommerce / Symfony 2.8-如何将自定义字段添加到注册表单

Question

Does anyone know a way to add an extra field (VAT ID provided by the Infinitepay Bundle) to oroCommerce's registration form? I can't find a way to do it.

The issue is that this field isn't part of the CustomerUser entity, but of the associated Customer entity. So the normal builder->add() command doesn't work. I'm also having trouble finding a way to put any code into a Bundle of my own and get it to work (instead of hacking the core). I've already read the Symfony docs, but they didn't help much.

Answer 1

First, you need to create symfony form extension, see documentation

Then add the VAT ID field to form builder and add a POST_SUBMIT listener with a lower priority than this one

In the listener's code, you can map the VAT ID value to the Customer entity.

UPD:

1. How exactly am I supposed to use form type extensions?

Ok. Use this gist

The documentation says they are good for extending field types, not forms.

It's the same. Any form type can be used as a child (field) of another form type.

I can't do it with $builder->add() - that gives me a 500 error because the entity doesn't have that field.

You should add an option 'mapped => false' for your field. See documentation

I also need a way to put it in a bundle of my own, not into the core.

You can modify any form type from your own bundle using form type extensions. This is what they were created for.
