Question

我找到了一个与我类似的问题的答案，但是我不明白它的工作原理以及我应该在代码中进行哪些更改。所以，我请求您帮助，我收到此错误消息：

选项“ 0”不存在。定义的选项为：“操作”，“ 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”，“数据”，“ data_class”，“已禁用”，“ empty_data”，“ error_bubbling”，“ error_mapping”，“ extra_fields_message”，“ help”，“ help_attr”，“ heritit_data”， “ invalid_message”，“ invalid_message_parameters”，“ label”，“ label_attr”，“ label_format”，“ mapped”，“ method”，“ post_max_size_message”，“ property_path”，“ required”，“ translation_domain”，“ trim”，“ upload_max_size_message “，” validation_groups“。

这是我的类型：

}

希望您能理解我的英语，并且有人可以帮助我（并向我解释如何避免再次犯此错误）

Thx

编辑：

中的那些useless []有问题

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

，我已解决但错误消息相同

Answer 1

我认为您的[]太少了：

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

Answer 2

这里您缺少标签属性：

->add('description', TextType::class, ['required' => false, 'Description'])

Symfony 4类型：选项“ 0”不存在
