I figure I would just share how I handle multiple uploads in CI, it's a little different than your method:

Form looks like this:

Upload/multiple_upload function in controller looks like this:

function multiple_upload()
{
    $config['upload_path'] = './userpics/originals/'; // server directory
    $config['allowed_types'] = 'gif|jpg|png'; // by extension, will check for whether it is an image
    $config['max_size']    = '512'; // in kb
    //$config['max_width']  = '1024';
    //$config['max_height']  = '768';

    $this->load->library('myupload');
    $error = array(); $data = array();
    for ($i=0;$imyupload->initialize($config);
            if (!$this->myupload->do_upload('userfile',$i)) {
                    $error[] = $this->myupload->display_errors();
            }
            $data[$i] = $this->myupload->data(); //gradually build up upload->data()
    }

    if ( count($error) > 0 )        
    {
        print_r($error);
    }    
    else
    {
        print_r($data);
    }
}    

At this point I made a copy of CI upload class, and pasted it into my applications library directory. A few changes need to be made. I named it myupload.

@ Line 143:

public function do_upload($field = 'userfile')

change to

public function do_upload($field = 'userfile', $i = 0)

Any lines in this function above line 200, you must add [$i] to the end of the $_FILES variables.

Example:

is_uploaded_file($_FILES[$field]['tmp_name'])

change to:

is_uploaded_file($_FILES[$field]['tmp_name'][$i])

There are 9 lines to be updated.
