Hello ! First of all sorry for my awful english, I'm trying to be clear. I would like to add some custom field to the order (delivery date and time). I've found a "tutorial" yesterday, I've tried it, but no luck : - edited the order class -> added two new variable $date_delivery and $time_delivery - edited the order-carrier.tpl -> added two input My problem is : it seems there is no connection between db and ui, so my fields doesn't save to the db. (I also like add them to the outcome order confirmation e-mail , but it's anoter problem and maybe I can solve it, if I solve this problem). What am I missing ? I spend the whole night to figure this out, but no positive result .... Thank you for your time and help.
