致命錯誤：調用未定義的方法CI_Upload :: do_multi_upload（）codeigniter

Question

我已經擴展了CI_Upload類併爲圖像添加了multi_upload函數。這工作正常，但在本地服務器上，它拋出：

Fatal error: Call to undefined method CI_Upload::do_multi_upload() 

它沒有任何意義，因爲我試過，我發現使用谷歌沒有運氣幾種不同的解決方案。

這裏是我的 '應用程序/庫/ MY_upload.php' 類：

class MY_Upload extends CI_Upload { 
    var $return_value; 
function __construct($config = array()) 
{ 
    parent::__construct($config); 
} 


function do_multi_upload($field = 'userfile', $return_info = TRUE, $filenames = NULL){ 

     // Is $_FILES[$field] set? If not, no reason to continue. 
     if (! isset($_FILES[$field])) 
     { 

      $this->ci->set_error('upload_no_file_selected'); 
      return FALSE; 

     } 

     //If not every file filled was used, clear the empties 

     foreach($_FILES[$field]['name'] as $k => $n) 
     { 

      if(empty($n)) 
      { 

       foreach($_FILES[$field] as $kk => $f) 
       { 

        unset($_FILES[$field][$kk][$k]); 

       } 

      } 

     } 

     // Is the upload path valid? 
     if (! $this->ci->validate_upload_path($field)) 
     { 

      // errors will already be set by validate_upload_path() so just return FALSE 
      return FALSE; 
     } 

     //Multiple file upload 
     if(is_array($_FILES[$field])) 
     { 

      //$count = count($_FILES[$field]['name']); //Number of files to process 

      foreach($_FILES[$field]['name'] as $k => $file) 
      { 

       // Was the file able to be uploaded? If not, determine the reason why. 
       if (! is_uploaded_file($_FILES[$field]['tmp_name'][$k])) 
       { 

        $error = (! isset($_FILES[$field]['error'][$k])) ? 4 : $_FILES[$field]['error'][$k];

    } 

} 

?> 

而且控制器調用該函數：

$config = array(
    'allowed_types' => 'jpg|jpeg|gif|png', 
    'upload_path' => $this->image_path, 
    'max_size' => 1500000, 
    'remove_spaces' => TRUE, 

    ); 

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



if($files = $this->upload->do_multi_upload('userfile', TRUE)){ 
    } 
//Fatal error: Call to undefined method CI_Upload::do_multi_upload() in controllers/admin.php on line 160

唉唉確定...所以文件名稱區分在服務器上敏感！ 'MY_Upload.php' 笨蛋！
