上传代码点火器htaccess只是不工作

我创建了与CI用户指南完全相同的副本，甚至更改了
$this->upload->do_upload("name_of_file_input");我试过两种

./data/
./application/data/

作为我的文件夹上传，CHMOD 0777，仍然上传不起作用
我启动了FF和FireBug来查看我从本地主机发送/获得的头，我认为问题可能在.htaccess文件中，但不太确定。。。
我在子文件夹localhost/something/ (or http://192.168.0.101/sms/)
上工作我的routes.php应该很好，没有404或任何其他问题，除了上传脚本

同样奇怪的是，我必须制作这样的表格

<?=form_open_multipart("/sms/upload/do_upload")?>

它创建了这个

<form action="http://localhost/sms/sms/upload/do_upload" method="post" accept-charset="utf-8" enctype="multipart/form-data">

注意双sms/sms/这显然是错误的，但我的htaccess重定向正确，正如你在这里看到的

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单

<?=form_open_multipart("/upload/do_upload")?>

它给我带来了一个错误，当然是

HTTP/1.1 301 Moved Permanently
Date: Tue, 28 Aug 2012 01:52:43 GMT
Server: Apache/2.4.2 (Win32) OpenSSL/1.0.1c PHP/5.4.4
Location: http://192.168.0.101/upload/do_upload

且明显http://192.168.0.101/upload在我的本地主机上不存在，我的整个安装都在子文件夹/sms/

下我的.htaccess

<IfModule mod_rewrite.c>
# mod_rewrite rules
RewriteEngine on

 RewriteBase /sms/
# This will make the site only accessible without the "www."

新信息：

似乎在点击"上传"按钮后，它被重定向到"某个地方"（带有"附加"的数据），并从"某个位置"重定向到我的实际上传脚本，该脚本完成了所有工作（没有"附加"数据），因此我认为这是.htaccess的问题。CI抛出此错误

您没有选择要上载的文件。

<?php
class Upload extends CI_Controller {
function __construct()
{
    parent::__construct();
    $this->load->helper(array('form', 'url'));
}
function index()
{
    $this->load->view('upload_form', array('error' => ' ' ));
}
function do_upload()
{
    $config['upload_path'] = './data/';
    //$config['allowed_types'] = 'gif|jpg|png';
    //$config['max_size']   = '100';
    //$config['max_width']  = '1024';
    //$config['max_height']  = '768';
    //$config['file_name'] = $_FILES['userfile']['name'];
    $this->load->library('upload', $config);
    if ( ! $this->upload->do_upload("userfile"))
    {
        $error = array('error' => $this->upload->display_errors());
        $this->load->view('upload_form', $error);
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());
        $this->load->view('upload_success', $data);
    }
   }
  }
 ?>
