Codeigniter没有将视频上传到服务器，但已创建目录

Question

  

大家好，我有一个文件可以上传视频到服务器但是什么时候   在我的localhost上测试，它工作得非常好，但是当我移动到   服务器，只创建了目录，但视频不是   上传。

所以下面的代码确实获得了任何文件类型（只有Permitted）并将它们转换为.flv文件，然后将它们上传到服务器，然后将名称存储到数据库中。

  

我面临的另一件事是，当我点击上传视频文件时，   它确实出现了成功消息，但没有报告错误

        $err_msgs   ='';

这里的每件事都适用于我的localhost
