Hello,
The modifications in the email notification where about the loading of the "order number" and some other elements from the database when that data is not available in the order object passed in the trigger.
So yes, it is possible that the patch fix your issue for the coupon.
Now because the patch is composed of a lot different modifications in several files ; it will be very complicated for me to give you a full patch like that.
But you might be able to fix your specific problem with a modification in the order preload.
Replacing
foreach($fs as $f) {
if(isset($data->$f) && !isset($data->order->$f))
$data->order->$f = $data->$f;
}
By
foreach($fs as $f) {
if(isset($data->$f) && !isset($data->order->$f))
$data->order->$f = $data->$f;
if(isset($data->old->$f) && !isset($data->order->$f))
$data->order->$f = $data->old->$f;
}
Because HikaMarket 1.7.3 includes the support of product bundles ; it needs HikaShop 3 otherwise it could generate unwanted side effects.
Regards,
