Coupon info on order list page

Hi, I am struggling a bit with list of orders (on page /index.php?route=sale/order) - I would like to show if (and maybe which) coupon was used in order, so I would like to add another column at /admin/view/template/sale/order_list.tpl (line 134) with something like $order['coupon'], but I don't know where to add this info/parameter so that I can use it here. Can someone help me please?

Hi,

you can download free extension https://www.opencart.com/index.php?rout ... =SmartTech
which adds Invoice No to the order list in admin dashboard. You there find suggestion how make your own if you are little bit familiar with php of course...

Cheers

Great, thank you. It helped - I now managed to solve this.
