我创建了与CI 用户指南完全相同的副本，我什至更改了$this->upload->do_upload("name_of_file_input");
我都尝试了
./data/
./application/data/
作为我要上传的文件夹，CHMOD 0777，仍然无法上传。
我启动了 FF 和 FireBug 来查看我从本地主机发送/获取的标头，我认为问题可能出在 .htaccess 文件中，但不太确定……
我在子文件夹上工作，localhost/something/ (or http://192.168.0.101/sms/)
我的 routes.php 应该没问题，没有 404 或除了上传脚本之外的任何其他问题
另外奇怪的是我必须制作这样的表格
<?=form_open_multipart("/sms/upload/do_upload")?>
这创造了这个
<form action="http://localhost/sms/sms/upload/do_upload" method="post" accept-charset="utf-8" enctype="multipart/form-data">
注意double sms/sms/这显然是错误的，但是我的 htaccess 它正确重定向，如您在此处看到的
HTTP/1.1 301 Moved Permanently
Date: Tue, 28 Aug 2012 01:49:47 GMT
Server: Apache/2.4.2 (Win32) OpenSSL/1.0.1c PHP/5.4.4
Location: http://192.168.0.101/sms/upload
Content-Length: 337
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html; charset=iso-8859-1
如果我创建这样的表格
<?=form_open_multipart("/upload/do_upload")?>
它当然会很好地给我一个错误
HTTP/1.1 301 Moved Permanently

显然我的本地主机上不存在http://192.168.0.101/upload我的整个安装在子文件夹/sms/
我的 .htaccess下
<IfModule mod_rewrite.c>

新信息：
似乎在点击“上传”按钮后，它被重定向到“某处”（带有“附加”数据），并从“某处”重定向到我的实际上传脚本，该脚本完成所有工作（没有“附加”数据）因此我认为这是.htaccess的问题。CI 抛出此错误
您没有选择要上传的文件。
