所以我不断收到错误消息，说我没有选择要上传的文件。我按照codeigniter的站点示例，搜索了很多主题，但没有成功。请帮助我确定我缺少什么或做错了什么。这只是一个简单的 xml 上传，就像几个 kb 的。
控制器：
<? if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class upload extends CI_Controller{
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index(){
$this->load->view("uploadPage", array('error'=>''));
}
function theUpload(){
echo "uploading";
$config['upload_path'] = "./uploads/";
$this->load->library('upload', $config);
if(!$this->upload->do_upload('userfile')){
$error=array('error'=>$this->upload->display_errors());
$this->load->view("uploadPage", $error);
echo "no upload";
} else{
echo "file uploaded";
}
}
}
?>
的HTML：
<body>
<?php echo $error;?>
<?php echo form_open_multipart('upload/theUpload');?>
<input type="file" name="userfile" id="userfile"/>
<input type="submit" name="submit" value="Upload File">
</form>
</body>
如果有帮助，这是我的 htaccess
