I'm new in php and I learn a lot from stackowerflow. I'm working on some kind of warehouse script. Most of it is done but I have problems with quantity. When I create receipt or delivery note everything work fine but when I try to change quantity at this documents then I lost myself. it work like this when I create delivery note:
- search for buyer
- add the buyer
- search article
- add the article (manualy specify quantity), automaticaly update quantity at my lager (if I had 5 pcs and add 3 pcs my lager is 2 pcs)
in case I make a mistake and I wanna change quantity I add one button called EDIT so I can change it. Then troubles begin. I can change it at delivery note but I cant recover my lager. Because I'm totaly new I'm using the simpliest add, update and delete query. So I'm wonder Can I somehow update my lager after I finish my delivery note. Any idea how to solve my problem?
