Hello @Razi
I have custom field called proforma_invoice, I tried to print_r order.details, this field is present in that array.
but when I tried to access to $order.details.proforma_invoice in /themes/xxx/templates/customer/order-details.tpl, it doesn't work.
How can I access this varibale?
I have defined this varibale in Order.php file and I'm able to access this varibale from backoffice, but it's not working in frontoffice.
Thank you.
