Symfony 3在EntityType表单字段中获取对象数据

Question

I've got the Form with two EntityType fields

    public function buildForm(FormBuilderInterface $builder, array $options)
{
     $builder
        ->add('supplier', EntityType::class, array(
            'class'         => 'AppBundle:Supplier',
            'choice_label'  => 'pubName',
            'label'         => false,
            'expanded'      => true
        ))
        ->add('payment', EntityType::class, array(
            'class'         => 'AppBundle:Payment',
            'choice_label'  => 'pubName',
            'label'         => false,
            'expanded'      => true
        ));
}

And I want to get fields of passed objects in Twig template, so I could get the name, or description of every entity to customize my form view. How can I achieve that in the way?

Answer 1

You can create a custom type with EntityType as parent for both of your entities.

Take a look at this documentation page: https://symfony.com/doc/3.4/form/create_form_type_extension.html

Answer 2

You can access the current data of your form via form.vars.value :

{{ form.vars.value.supplier }} {# Your Supplier object #}
{{ form.vars.value.payment }} {# Your Payment object #}
