Symfony FOSRest ChoiceType

Question

我尝试使用FOSRest提交表单。到目前为止一切顺利，但我想知道choiceType接受哪种格式？它是一个关联数组吗？或者......？

FormType

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('name', TextType::class);
    $builder->add('roles', ChoiceType::class, [
        'multiple' => true,
        'expanded' => true
    ]);
}

提交的数据：

{"group":{"name":"esdfgh","roles":["ROLE_VIEW_ALL_CATEGORIES","ROLE_ADD_RECEIPTS","ROLE_EDIT_RECEIPTS","ROLE_VIEW_ALL_RECEIPTS"]}}

但是这会产生错误：＆＃34;此值无效＆＃34;在ChoiceType上。

Answer 1

您需要提供有效的choices

  

choices选项是一个数组，其中数组键是项目的   label和数组值是项的值

根据你的例子，应该是这样的：

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('name', TextType::class);
    $builder->add('roles', ChoiceType::class, [
        'choices' => [
         "ROLE_VIEW_ALL_CATEGORIES" => "ROLE_VIEW_ALL_CATEGORIES",
         "ROLE_ADD_RECEIPTS" => "ROLE_ADD_RECEIPTS"
        ]
        'multiple' => true,
        'expanded' => true
    ]);
}
