Many a time, the standard rules are not sufficient to create new promotional rules for a merchant offer. For anyone looking for Magento Development, we explain here the method to add a custom condition (discount applicable only for orders from mobile app) in Shopping cart price rules. Solution:

Step -1: Override the class Mage_SalesRule_Model_Rule_Condition_Address. (Copy the file Address.php from app/code/core/Mage/SalesRule/Model/Rule/Condition/ to app/code/local/Mage/SalesRule/Model/Rule/Condition/)

Step -2: Add the new condition (highlighted) in the $attributes array as given below $attributes = array( 'base_subtotal' => Mage::helper('salesrule')->__('Subtotal'), 'total_qty' => Mage::helper('salesrule')->__('Total Items Quantity'), 'weight' => Mage::helper('salesrule')->__('Total Weight'), 'payment_method' => Mage::helper('salesrule')->__('Payment Method'), 'shipping_method' => Mage::helper('salesrule')->__('Shipping Method'), 'postcode' => Mage::helper('salesrule')->__('Shipping Postcode'), 'region' => Mage::helper('salesrule')->__('Shipping Region'), 'region_id' => Mage::helper('salesrule')->__('Shipping State/Province'), 'country_id' => Mage::helper('salesrule')->__('Shipping Country'), 'only_for_app' => Mage::helper('salesrule')->__('Only for Mobile App'), /* Newly Added Condition */ ); Step -3: Now the condition will display in the shopping cart price rule, Admin -> Promotions -> Shopping Cart Price Rules -> Add New Rule -> Conditions -> Add New. Step -4: To validate this new condition while applying shopping cart price rules, add the below condition (you shall change condition according to your requirement) into validate function public function validate(Varien_Object $object) { : : if ($this->getAttribute() == 'only_for_app') /* checking new condition */ { /* Your custom logic to validate the condition */ if(Mage::getSingleton('core/session')->getMobile()) { return true; /* If validation success apply rule */ } } : : return parent::validate($object); } Step -5: After adding your logic invalidate function, create the shopping cart price rule with your own new condition and check it out from the front end.
