Apply discount on subtotal (order editor)

[royal38]

Hello,

 

I use the contrib order editor which is great but I have a little bug with it : Discount don't apply on subtotal, only on total.

 

Because of that, tax and price excluding tax are wrong because there are based on the subtotal.

 

 

As you can see, subtotal don't include the discount :angry: but is included in the total. :blink:

 

I try all this afternoon to modify the file order.php which is in the file "order_editor", but I failed to apply "discount" which is a custom on the subtotal.

 

I don't know how to apply discount on this code :

 

 

Thanks a lot for your help.

 

Bye ;)
