Reduction amount/percent in order details in ACP

[shutzu]

Title says it all, how can I do that?

tried addiing in AdminOrders.php at line 530

('.$product['reduction_price'].')

not working

Any other ideas?

Or how can I see if a product has price reduced or not on the order detail page. (make it bold if price is reduced)


EDIT:

Adding the line below instead of the first code seems to move something. a big 0 appears in brackets

('.Tools::displayPrice($discount['value'], $currency, false).')
