I have a stock of books. When I get new copies to the stock, I need to update the number of copies
id book copy[/u]
1 Raven 3
What function could I use and where? maybe afterSave function in the model (?)
I don’t want just update the number in admin. I need to:
insert number of new copies in a form
let the function handle the calculations
update the number of copies in the table
Fx there are 3 copies in the table.I get 2 more copies so I there should be 5 copies instead of 3 in the table.
You could use beforeSave for that
protected function beforeSave()
// increase your database counter, here
Thank you for reply.
anyway, the problem is the database counter. table:library, column:copy. I need to change the number of copies based on user input.
meaning user form input + current number of coppies = [b]updated number of copies in the table (column copy)
