Symfony2 custom radio_widget entity access - php

Question

I have a form with 3 entity fields displaying radios input.
->add(
'membership',
'entity',
array(
'class' => 'Comiti\UserBundle\Entity\Membership',
'expanded' => true,
'multiple' => false,
'label' => false,
'empty_value' => 'Aucune adhésion',
'query_builder' => function (MembershipRepository $er) {
return $er->createQueryBuilder('membership')
->where('membership.club = :club')
->setParameter('club', $this->authentication_service->getCurrentClub())
->orderBy('membership.name', 'ASC')
;
},
)
)->add(
'federal_license',
'entity',
array(
'class' => 'Comiti\UserBundle\Entity\FederalLicense',
'expanded' => true,
'multiple' => false,
'label' => false,
'empty_value' => 'Aucune licence',
'query_builder' => function (FederalLicenseRepository $er) {
return $er->createQueryBuilder('federal_license')
->where('federal_license.club = :club')
->setParameter('club', $this->authentication_service->getCurrentClub())
->orderBy('federal_license.name', 'ASC')
;
}
)
)->add(
'insurance',
'entity',
array(
'class' => 'Comiti\UserBundle\Entity\Insurance',
'expanded' => true,
'multiple' => false,
'label' => false,
'empty_value' => 'Aucune assurance',
'query_builder' => function (InsuranceRepository $er) {
return $er->createQueryBuilder('insurance')
->where('insurance.club = :club')
->setParameter('club', $this->authentication_service->getCurrentClub())
->orderBy('insurance.name', 'ASC')
;
}
)
);
I need to define a custom template for those radios input that put in each input an attr whith "data-price".
i made this:
{%- block radio_widget -%}
<input type="radio" data-price="{{Myprivcevar}}" {{ block('widget_attributes') }}{% if value is defined %} value="{{ value }}"{% endif %}{% if checked %} checked="checked"{% endif %} />
Is there any possibility to access to {{MypriceVar }}
I am on Symfony 2.6

You can add attributes to an input without creating a custom template:
{{ form_widget(yourRow, {'attr': {'data-price':'yourValue'}}) }}
Example:
{{ form_widget(choiceFormView, {'attr': {'data-price':'2'}}) }}
result in
<input type="radio" id="form_choice_0" name="form[choice]" required="required" data-price="2" value="1" checked="checked">
