Symfony4-处理带有表单收集原型的数据原型发送

Question

我现在要添加附件的邮件表单（功能性邮件）。

我先前创建的上载收藏集的附件，问题是：

• 当我向此表单添加默认值时
  （在控制器中创建表单之前，基本上是$ form-> addPiece（上传））正确显示的字段或可以传递数据的字段，或者我希望选择不显示默认字段
• 当我不符合默认字段时，我会使用javascript显示原型，但是当我验证表单时，该集合中的任何数据都不会发送到控制器

MailType.php

                'entry_type' => UploadType::class,
                'entry_options' => ['label' => false],
