FormBuilder 如何反转 ChoiceList 的内容

Question

实际上我从 EntityType 创建了一个 ChoiceType (https://symfony.com/doc/current/reference/forms/types/choice.html)，我想反转恢复的数据。

$formMapper
        ->with('Niveau', ['class' => 'col-md-12'])
        ->add('number', EntityType::class, array('required' => true, 'label' => 'NUMBER',
            'class' => Number::class,
            'choice_label' => 'info',
        ))
        ->end();

示例：我得到 [1, 2, 3, 4, 5] 并且我想要 [5, 4, 3, 2, 1] 在我的选择列表中。

有没有办法按 DESC 而不是 ASC 排序？我应该从 NumberRepository 调用请求吗？

我认为这就是您所需要的：

$builder->add('users', EntityType::class, array(
    'class' => User::class,
    'query_builder' => function (EntityRepository $er) {
        return $er->createQueryBuilder('u')
            ->orderBy('u.username', 'ASC');
    },
    'choice_label' => 'username',
));
