How to show the total discount amount on PDF invoices and packing slips receipt

  • Hey,

    First I want to say, what a great plugin!

    We are using Pdf invoices and packing slips plugin for generating the receipts. Is it possible to add the total discount amount to the receipt aswell? For custom fields its nessesary to add <?php $wpo_wcpdf->custom_field(‘custom_fieldname’, ‘Custom field:’); ?> to the Pdf invoices and packing slips template. My question is how should I modify this given code to fetch the total discount amount from your POS plugin?

    Another thing that is bothering me is that when the order total is 0 then it still calculates the tax amount like so: Total 0,00 € (inc. 0,54
    € VAT 24%)

    Please help me!
