       $builder->add('name', 'entity', array(
    'class' => 'AcmeIndexBundle:Provincia',
    'query_builder' => function(EntityRepository $er) {
        return $er->createQueryBuilder('u')
            ->orderBy('u.name', 'ASC');
    },'empty_value' => $options['prova'] 
));

    }

but not work why?

Answer 1

Simply pass it to the constructor :

$this->createForm(new ProvinciaType($options), $provincia)

And use it in the form :

public function __construct($options) {
    $this->options = $options;
}

Then use this in buildForm :

$options = $this->options;
....
function(EntityRepository $er) use ($options)
    ...
},'empty_value' => $options['prova'] 
....
