Answer 1

您应该提供覆盖config参数

$config['upload_path'] = './uploads/';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);
$this->upload->initialize($config);

请参阅上传首选项的文档

Answer 2

我认为你想使用CodeIgniter上传多个文件。如果我是对的那你必须遵循这个答案，那么你肯定得到了解决方案。

在视图页面中

<form action='index.php/upload/do_upload' enctype="multipart/form-data" method="post">  
   <input type="file" name="userfile[]" multiple='multiple' />
   <input type="submit" value="upload" />  
</form>

在控制器中。

public function do_upload()
{
    $config['upload_path']          = './uploads/';
    $config['allowed_types']        = 'gif|jpg|png';
    $config['max_size']             = 10000;
    $config['max_width']            = 1024;
    $config['max_height']           = 768;
    $config['overwrite']            =  true;

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

    $number_of_files_uploaded = count($_FILES['userfile']['name']);

    for ($i = 0; $i < $number_of_files_uploaded; $i++) {
       $_FILES['upl_files']['name']     = $_FILES['userfile']['name'][$i];
       $_FILES['upl_files']['type']     = $_FILES['userfile']['type'][$i];
       $_FILES['upl_files']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
       $_FILES['upl_files']['error']    = $_FILES['userfile']['error'][$i];
       $_FILES['upl_files']['size']     = $_FILES['userfile']['size'][$i];

       if ( ! $this->upload->do_upload('upl_files'))
       {
          $error = array('error' => $this->upload->display_errors());
          var_dump($error);
          $this->load->view('v_upload', $error);
       }
       else
       {
          $data = array('upload_data' => $this->upload->data());

          var_dump( $data);
       }    
    }  
 }

请关注这个名字，这是重要的一部分。
