Hi,
@lousyfool :
This is a recent addition to HikaShop. It was added less than a year ago.
So it was mainly mentioned in a blog post. There is no mention of it in the documentation yet.
@Thrane:
I don't know what tag you used exactly but it works fine on my end.
Regarding the code form the other thread, you can replace the line:
$app->enqueueMessage(JText::sprintf('MISSING_QTY_FOR_FREE_SHIPPING',$diffQty));
with:
$app->enqueueMessage(JText::sprintf('MISSING_QTY_FOR_FREE_SHIPPING',$this->currencyClass->format($diffQty, $this->full_total->prices[0]->price_currency_id)));
and it will display the price well formatted with the currency symbol etc.
