I get the code like this:


1 Answer 1



couponCode = $param['code'] 
$oCoupon = Mage::getModel('salesrule/coupon')->load($couponCode, 'code');
$oRule = Mage::getModel('salesrule/rule')->load($oCoupon->getRuleId());

Then try to apply it to your order see Check if coupon is valid for a quote

  • try to apply oRule with setCouponCode? Feb 10, 2015 at 20:00
  • Suppose a coupon os valid until yesterday and I would execute this code. Would it then return an error or empty? Mar 18, 2016 at 14:44
