关于文件上传的问题，这样写对不对呢？

view:
------------------------------------

<div>
  <label for="cardid_pic">idcard：</label>
  <input type="file" name="cardid_pic" id="cardid_pic" />

controller:
---------------------------
$cardid_pic = $this->input->post('cardid_pic');
//将文件上传到服务器
$data_result['result_upload'] = $this->becometgmember_model->UploadFile($cardid_pic);


model:

                $this->load->library('upload',$config);

                print_r($this->upload->do_upload());

                if ($this->upload->do_upload()){
                        foreach ($this->upload->data() as $v){
                                $data['file_type'] = $v->file_type;
                                $data['raw_name'] = $v->raw_name;
                                $data['orig_name'] = $v->orig_name;
                                $data['file_size'] = $v->file_size;
                                $data['image_width'] = $v->image_width;
                                $data['image_height'] = $v->image_height;
                        }
                        return $data;
                }else{
                        return FALSE;
                }
        }

错误提示：
----------------------
You did not select a file to upload.

问题：
------------------------
怎么才能将选择的文件传递到model中？post好像不行。

你的文件域的name错了,应该是userfile,如果你在Upload类里改过了,就不是这个问题;如果没改,那么就是你的文件域的name错了,

$cardid_pic = $this->input->post('cardid_pic');
//将文件上传到服务器
$data_result['result_upload'] = $this->becometgmember_model->UploadFile($cardid_pic);

这些没必要。设置
$field_name = "cardid_pic";
  $this->upload->do_upload($field_name);
