I need today-only help refining my custom invoice that is generated with the “PDF Invoices & Packing Slips” plugin for WooCommerce. The invoice template is already in place, but I have two quick code changes left: • Tweak a couple of existing fields (just label and placement adjustments inside the PHP/HTML template). • Inject a new “Discount details” field so every generated PDF shows the order’s discount information alongside existing totals.
