I'm running Magento 1.8 Community edition. I have a product with one custom choice.

So I add the choices and give them SKU NO INSTALLATION with SKU:TILLV000 INSTALLATION with SKU: TILLV001 SUPER INSTALLATION with SKU: TILLV002

Now IF you choose any of the custom choices with SKU: TILLV001 OR TILLV002. Rhen I would like to enable free shopping.

I added that as a shopping cart rule

If ALL of these conditions are TRUE : If an item is FOUND in the cart with ANY of these conditions true: SKU is TILLV001, TILLV002

It doesnt apply? What have I done wrong?

Magento does not take into account custom options when calculate shopping cart rules unless you have an extension for this.

We do the following trick: rewrite class Mage_SalesRule_Model_Rule_Condition_Product and add 2 new custom attributes 'Custom Options SKU' and 'Custom Options Values'

Then get options to validate as $options = $product->getTypeInstance(true)->getOrderOptions($product);

and SKU as $object->getSku() where $object is the quote item.

  • The file path is app\code\core\Mage\SalesRule\Model\Rule\Condition\Product.php for the original magento file, and I think you need to create a new local module to rewrite it.

  • Not sure I follow after you add the attribute to _addSpecialAttributes() - If I add a new attribute to the select element using: $attributes['quote_item_myattribute'], do I simply need to set this to $product in the validate() method? Ie: $product->setQuoteItemMyattribute($object->getMyattribute())?
