Codeigniter中的文件上传错误

I am trying to upload an image in codeigniter.

here is my view file code.

<form action="<?php echo site_url('pages/data_submitted') ?>" method="get" enctype="multipart/form-data">
Image: <input type="file" name="image"/>
<button>Submit</button>
</form>

and this is my controller code.

class Pages extends CI_Controller 
{ 
 public function data_submitted(){
 $config['upload_path']   =   "img/";
$this->load->library('upload',$config);
$this->upload->do_upload();
$finfo=$this->upload->data();
$data = $this->upload->display_errors();

$this->load->model('user_model');
$this->user_model->insert_item($data);
}
}

and here is my model code

<?php
class User_model extends CI_Model {
function __construct(){
    /* Call the Model constructor */
    parent::__construct();
}


public function insert_item($item){

    print_r($item);
}
}
?>

What is wrong with this code... Here I passed $data just to check whether any error occur or not. And it is showing "You did not select a file to upload.' even I select a file. please help me.

  class Pages扩展CI_Controller 
 {
公共函数 data_submitted（）{
 $ config ['upload_path'] =“img /”; 
 $ this-＆gt; load-＆gt; library（'upload'，$ config）; 
 $ this-＆gt; upload-＆gt  ; do_upload（）; 
 $ finfo = $ this-＆gt; upload-＆gt; data（）; 
 $ data = $ this-＆gt; upload-＆gt; display_errors（）; 
 
 $ this-＆gt; 负载＆GT;模型（ 'user_model'）; 
 $的这 - ＆GT; user_model-＆GT; insert_item（$数据）; \ N} \ N} 
   
 
 
这里是我的模型代码 
 
 
 ＆lt;？php 
class User_model extends CI_Model {
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ @  :: __ construct（）; 
} 
 
 
公共函数insert_item（$ item）{
 
 print_r（$ item）; 
} 
} 
？>＆gt; 
  <  / pre> 
 
 
此代码有什么问题... 
我传递$ data只是为了检查是否发生错误。  
它显示“您没有选择要上传的文件。” 即使我选择了一个文件。
请帮助我。

    Refer this code. this will surely work for you

    public function uploadImage() {
        $this->load->helper(array('form', 'url'));  
        $config['upload_path'] = 'assets/images/b2bcategory';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '1000';
        $config['max_width'] = '2024';
        $config['max_height'] = '1768';
        $config['width'] = 75;
        $config['height'] = 50;
        if (isset($_FILES['catimage']['name'])) {
            $filename = "-" . $_FILES['catimage']['name'];
            $config['file_name'] = substr(md5(time()), 0, 28) . $filename;
        }
        $config['overwrite'] = TRUE;
        $config['remove_spaces'] = TRUE;
        $field_name = "catimage";
        $this->load->library('upload', $config);
        if ($this->input->post('selsub')) {
            if (!$this->upload->do_upload('catimage')) {
                //no file uploaded or failed upload
                $error = array('error' => $this->upload->display_errors());
            } else {
                $dat = array('upload_data' => $this->upload->data());
                $this->resize($dat['upload_data']['full_path'],           $dat['upload_data']['file_name']);
            }
            $ip = $_SERVER['REMOTE_ADDR'];
            if (empty($dat['upload_data']['file_name'])) {
                $catimage = '';
            } else {
                $catimage = $dat['upload_data']['file_name'];
            }
            $data = array(            
                'ctg_image' => $catimage,
                'ctg_dated' => time()
            );
            $this->b2bcategory_model->form_insert($data);

        }
    }
