We need small fix in our pdf invoice for oscommerce webshop.
If we add anything negative like a discount or credit note it add to the total instead of subtract.
Also need an extra option pdf.
the pdf is not standard oscommerce but created specially for us.
with template in (pdf) in.
We need another pdf for Tax free orders,which means total tax column out and red rext text free (in Dutch) .
So the link must gave query like if tax href = odf normal when is tax in, and pdf_tax-free for orders without any tax.
so that if tax free the link is changed automatically.
only bid if you know FPDF AND oscommerce
