Call below function every time before do_upload

$this->upload->initialize($upload);

Assume all files in this array

$_FILES['userfile']['name']
then your script would look like

        $this->load->library('upload');     for ($k = 0; $k < count($_FILES['userfile']['name']); $k++) {         $this->upload->initialize($upload); //must reinitialize to get rid of your bug ( i had it as well)         if (!$this->upload->do_upload('userfile',$k)) {             $this->load->view('upload/image_form', $data + array('error'=>$this->upload->display_errors()));         }         $udata[$k] = $this->upload->data(); //gradually build up upload->data()     }

回答2:

if you look at the CI manual you have to provide the field name for the upload.

$field_name = "some_field_name"; $this->upload->do_upload($field_name);

you will need to do this for each of the different files you want to update, perhaps in a loop.
