I want to apply a 10 percent discount for the whole total. However, if the discount amount is greater than $100, I would like to only apply $100 fixed price instead of 10%. For example if 2 items total to $200, the 10% will apply and if the total is $2,000, only apply $100 discount.
I am using an observer
sales_quote_collect_totals_after
and that seems to work but don't know the code logic.
$discountAmount= ((float) $oCoupon->getDiscountAmount()/100) *$total;
if ($discountAmount>100) {
foreach($quote->getAllItems() as $item){
$item->setDiscountAmount(100);
$item->setBaseDiscountAmount(100);
$item->setCustomPrice($total - 100);
$item->getProduct()->setIsSuperMode(true);
$item->save();
}
}
Every time I run this code, the item changes its price and the whole total as well. I don't want the items to change their price, only the grand total and the discount amount. Does any one know how I would go about doing this.
Thanks.
May this can help you check that out.as keep the code that much you needed.
