Hello,
I must modify invoice template and add tax value calculations not only for whole invoice but separately to every position(product) on invoice.
Products have different tax values.
I've added columns called tax
to invitems
and invoicedetails
tables and I'm looking for place where invoice positions are calculated on ex. keyup events.
I also should change invoice tax field behaviour - it should contain now the sum for tax position of every invoice product and be readonly.
The second question is:
when I press add invoice invoices_add.php
is fired and, automaticly, product called Title 1
(id=1) from invitems
table is added as the first position of invoice.
How to change that to any other invitems row as a default for adding new invoice?
Can you help me?
Regards,
Jacek
