php - Symfony 4 类型：选项“0”不存在

Question

我找到了与我的类似问题的答案，但我不明白它是如何工作的以及我应该在我的代码中更改什么。所以我请你帮忙，我有这个错误信息：

选项“0”不存在。定义的选项有：“action”、“allow_extra_fields”、“allow_file_upload”、“attr”、“auto_initialize”、“block_name”、“by_reference”、“compound”、“constraints”、“csrf_field_name”、“csrf_message”、“csrf_protection” ", "csrf_token_id", "csrf_token_manager", "data", "data_class", "disabled", "empty_data", "error_bubbling", "error_mapping", "extra_fields_message", "help", "help_attr", "inherit_data", “invalid_message”、“invalid_message_parameters”、“label”、“label_attr”、“label_format”、“mapped”、“method”、“

这是我的类型：

    {
        $resolver->setDefaults([
            'data_class' => Property::class,
        ]);
    }
}

希望你能理解我的英语，有人可以帮助我（并解释我如何避免再次犯这个错误）

谢谢

编辑：那些无用的[]有问题

->add('equipments', EntityType::class, [
            'required' => false,
            'label' => 'Equipements',
            [
                'class' => Equipment::class,
                'multiple' => true,
                'expanded' => true,
                'choice_label' => 'name'
            ]
        ])

，我解决了，但错误信息是一样的

我认为你的 [] 太少了：

->add('equipments', EntityType::class, [
            'required' => false,
            'label' => 'Equipements',
            //[
                'class' => Equipment::class,
                'multiple' => true,
                'expanded' => true,
                'choice_label' => 'name'
            //]
        ])
