Symfony2 + FOSUserbundle + dynamic change validation groups

Question

I am new with Symfony2 and so I am with FOSUserbundle, the registration form I wrote got different fields mandatory based on if it is a company or private person, I set it up etc and if I hardcode the valdiation group in the fos config it will work, but what I need is to set it up dynamic based on the form submit data, I tried to follow: http://symfony.com/doc/current/book/forms.html#book-forms-validation-groups

Seeing that FOSUserbundle use the deprecated OptionsResolverInterface , I even tried it with that one, but whatever I do it is never called.

So my question is kinda, what is the right approach with that bundle to change the valdiation group on the fly based on the submitted data?

Answer 1

Figured it out myself how to do and because I could nowhere on the internet find the solution, answering here my own question for the case someone else need that too:

in the config.yml i set the validationgroup like this

validation_groups: [AppBundle\Form\Type\RegistrationFormType, determineValidationGroups]

and inside that class then:

public static function determineValidationGroups(FormInterface $form){
...
}

And that one returns an array with the validations groups, just dont forget to include for registration for example Registration or it wont validate if the user already exists etc
