我在我的项目中使用文件上传.我想为我要上传到数据库中的文件设置修订号.即我将第一次上传sd.doc文件，将其保存为版本1.下载该文件后，我将进行一些更改，并将其保存为版本2.在查看时，应同时显示两者版本，我应该根据版本选择文件.谁能帮我解决这个问题.

Hi,

I am using the file upload in my project. I like to set the revision number for the file which I am uploading in the database. i.e. I will upload a sd.doc file for first time it will be saved as version 1. After I am downloading that file I will make some changes and I will save that it should be saved as version 2. While viewing it should show both the version and I should choose the file based on the version. Can any one help me to solve this issue.

Thanks in Advance.

推荐答案

每次保存文件时，都需要将修订号设置为新的修订号.
因此，请参见此处 [ ^ ].

You need to set the revision number to a new one everytime a file is saved.
