Menu order Up or Down

[eluser]Unknown[/eluser]
Hi!

I'm very new to Codeigniter and PHP. But I am right now trying to make menu fully dynamic so that my client can change title, url and order on the site menu.

I can't find any help or anything on how to change the menu order (+1 or -1). It would be very nice if you could help me with this.

I do have a database with a "order" column. Wich I place the orderID in.

Would be very kind if you could help me. Thanks!
