How to add mapping to a form

I have a form which I create using a form class. One field of this form is country_id, which gives me a country id in a text field.

However, I want create a select field instead, and not only with all ids, but rather with country names mapped by those ids.

I have a table in a database mapping country ids to names. However, the form uses only one entity, not this one.

How can I create that select using this other table here? How can I solve this?

Thanks!

EDIT:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', 'text', ['required' => false])
            ->add('address', 'text', ['required' => false])
            ->add('zipCode', 'text', ['required' => false])
            ->add('city', 'text', ['required' => false]);

        $builder->add('country', 'entity', [
            'class'    => 'AcmeBundle:Country',
            'property' => 'shortName',
            'required' => false,
        ]);

        // $builder->add('country', 'text', ['required' => false]);

        $builder->add('number', 'text', ['required' => false]);
    }

That's the whole method inside the, let's call it, Foo entity. It generates proper HTML with ids as values, but there are still those errors I mentioned in the comment.

You need the entity Field Type. Your FormType should look like this:

$builder->add('country', 'entity', array(
    'class' => 'YourBundle:Country',
    'property' => 'name',
));

Checkout the docs for more info.
