php - Symfony表单未显示正确的错误(正在星座图上)

Question

我对表单的约束检查和错误的正确显示存在问题。
问题描述
该表单具有三个复选框，其中两个复选框是用户必须检查的(接受“条款和条件” Material )。

如果仅一个强制性复选框(第一个或第二个)未选中，则错误显示正确

如果未同时选中两个必需复选框，则所有

都不会显示错误

分析已经完成

遍历错误link表明没有错误

如果我在表单中添加其他文本字段，上述问题将消失(但我不希望该字段)。

BookingTermsAndConditionsFormType.php

    public function buildForm(FormBuilderInterface $builder, array $options) {

        $builder

                'label'      => 'accept <a href="#" target="_blank">Terms and Conditions</a>.*',

怎么了

Answer 1

请在这里找到我的解决方法。
我添加了一个附加字段，并使用了HiddenType。这使形式错误可以正常工作。不要问我为什么...
BookingTermsAndConditionsFormType.php

[...]

$builder
    ->add('dummy', HiddenType::class, [
        'label' => 'i am stupid and only needed because constrain-errors are not 
                    displayed correctly without me (e.g. in the case both mandatory 
                    checkboxes are not checked).'
    ])
