我有一个基于非实体的表单，它使用XSD架构构建，我的问题是，当我提交表单时，除文件外一切正常..
处理提交表单时有处理权：
$value[$sectionName]['photo'] ='/Upload/'.$field->getClientOriginalName();
$field->move($dir, $field->getClientOriginalName());
使用文档：https://symfony.com/doc/current/controller/upload_file.html 我认为，要上传我的文件，我只需要使用move（）函数。
最奇怪的是，文件上传到我想要的地方，在我的上传/上传中。目录。
但是当我的页面重新加载时，FileType为空白，内部没有文件。
感谢提前帮助。抱歉我的英语不好，早上好！

This is the expected behaviour, so that if you submit the form again, the file won't be re-uploaded unnecessarily.
It sounds to me like your upload code is working fine but you have a small misunderstanding of how the HTML File input behaves. The input field temporarily holds the path to the file on your local machine - not the uploaded file.
If you want to see the uploaded file (path), you need to do some custom coding in your form to make that happen.
