Sådan uploader du flere billeder ved hjælp af codeigniter

Kald nedenstående funktion hver gang før do_upload

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

Antag alle filer i dette array

$_FILES['userfile']['name']
så ville dit script se ud

        $this->load->library('upload');
    for ($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()
    }
