如何在Symfony DateType字段中设置日期范围？

Question

我需要在窗体的dateType字段上的最小和最大日期上设置范围。我的代码在这里。

 public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('date',DateType::Class, array(
        'widget' => 'single_text',
        'attr' => array(
            'min' => new \DateTime(),
            'max' => new \DateTime('+7 day'),
    )));
}

 public function buildForm(FormBuilderInterface $builder, array $options){
       $builder->add('date',DateType::Class, array(
                 'widget' => 'choice',
                 'years' => range(date('Y'), date('Y')+100),
                 'months' => range(date('m'), 12),
                 'days' => range(date('d'), 31),
               ));
 }
