I have a shopping cart rule setup which applies a discount if the product has a specific attribute - there's no coupon code involved.

Throughout the site I just need to check whether or not that shopping cart rule has been applied to the quote.

I've tried this:

$coupon_code = Mage::getSingleton('checkout/session')->getQuote()->getCouponCode();

But that doesn't work; it only works with coupon codes input by the user.

How would I check if such a shopping cart rule has been applied?

$appliedRuleIds = Mage::getSingleton('checkout/session')->getQuote()->getAppliedRuleIds();

This will give you the ids of the rules applied to the quote separated by comma.
you can turn them into an array like this:

$appliedRuleIds = explode(',', $appliedRuleIds);

if you want to get the rules applied as objects you can do this:

//$rules = Mage::getModel('salesrule/rule')->getCollection()->addFieldToFilter('rule_id' => array('in' => $appliedRuleIds));
$rules =  Mage::getModel('salesrule/rule')->getCollection()->addFieldToFilter('rule_id' , array('in' => $appliedRuleIds));

foreach ($rules as $rule) {
    //do something with $rule
}
  • hi marius, i have to apply similar solution. but getAppliedRuleIds stores both catalog price rule and shopping cart price rule. Now if the field value is only 6 (which is catalog price rule) and a shopping cart price rule too exists in store with id 6. in this case, with your solution, how can we define which one was applied ? shopping cart price rule or catalog price rule ? any help is appreciated. – Reena Parekh Jun 26 '15 at 14:24
  • @ReenaParekh. I'm almost certain the getAppliedRuleIds does not return the catalog price rules applied to the quote/order. Only shopping cart price rules that are applied. – Marius Jun 26 '15 at 14:27
  • Hi @Marius , I too need to get the same thing what you have mentioned in above code in magento2.2.2. So Please tell me how do I solve the same issue in magento 2 – Jaisa Feb 28 '18 at 7:28
