CI框架上傳csv文件

今天遇到在用CI框架上傳csv文件時報錯問題：

The filetype you are attempting to upload is not allowed.

是類型不容許，想到CI框架的config/mimes.php的配置，發現已經有csv的mimes配置，並且在win7下是能夠上傳的

因而百度之，半天沒結果，果真換google，找到以下的記錄：

The answer to my problem was with MIME types—I’ll leave this comment up here in case it is related. My CSV was returning with a MIME type of text/plain instead of any of the many acceptable CSV MIME types, so I just added text/plain to the csv entry in application/config/mime.php

因而在config/mimes.php中的csv數組中加入  text/plain，問題解決
