            $this->load->library('upload', $config);
            if($this->upload->do_upload())
            {   $data = array('upload_data' => $this->upload->data());  }
            else{   $error = array('error' => $this->upload->display_errors()); }
        }

    }

Please change your PHP code and try this out

$this->upload->do_upload()

to

$this->upload->do_upload($field_name)

where $field_name is your input name attribute.
