TOPIC: substraction of field and then update mysql

substraction of field and then update mysql 13 years 2 months ago #16433

hi,

I am trying to make a form where its possible to "pick" an item and when you submit then it should substract to amount and sum-up the mysql with the "new" amount.

Ex.
10 apples

A user type or choose the amount of apples - lets say 2.

On submit it should substract 10-2 and then update mysql with 8.

Can anyone give me an idea to solve this?

Regards,

Michael (Denmark)
