copied!<p>After digging a bit into Magento's core code, I found that you need to use <code>$item->getProduct()->setIsSuperMode(true)</code> in order to make <code>$item->setCustomPrice()</code> and <code>$item->setOriginalPrice()</code> work.</p> <p>Here is some sample code you can use within an Observer that listens for the <code>checkout_cart_product_add_after</code> or <code>checkout_cart_update_items_after</code> events. The code is logically the same except <code>checkout_cart_product_add_after</code> is called for only one item and <code>checkout_cart_update_items_after</code> is called for all items in the cart. This code is separated/duplicated into 2 methods only as an example.</p> <h3>Event: checkout_cart_product_add_after</h3> <pre><code>/** * @param Varien_Event_Observer $observer */ public function applyDiscount(Varien_Event_Observer $observer) { /* @var $item Mage_Sales_Model_Quote_Item */ $item = $observer->getQuoteItem(); if ($item->getParentItem()) { $item = $item->getParentItem(); } // Discounted 25% off $percentDiscount = 0.25; // This makes sure the discount isn't applied over and over when refreshing $specialPrice = $item->getOriginalPrice() - ($item->getOriginalPrice() * $percentDiscount); // Make sure we don't have a negative if ($specialPrice > 0) { $item->setCustomPrice($specialPrice); $item->setOriginalCustomPrice($specialPrice); $item->getProduct()->setIsSuperMode(true); } } </code></pre> <h3>Event: checkout_cart_update_items_after</h3> <pre><code>/** * @param Varien_Event_Observer $observer */ public function applyDiscounts(Varien_Event_Observer $observer) { foreach ($observer->getCart()->getQuote()->getAllVisibleItems() as $item /* @var $item Mage_Sales_Model_Quote_Item */) { if ($item->getParentItem()) { $item = $item->getParentItem(); } // Discounted 25% off $percentDiscount = 0.25; // This makes sure the discount isn't applied over and over when refreshing $specialPrice = $item->getOriginalPrice() - ($item->getOriginalPrice() * $percentDiscount); // Make sure we don't have a negative if ($specialPrice > 0) { $item->setCustomPrice($specialPrice); $item->setOriginalCustomPrice($specialPrice); $item->getProduct()->setIsSuperMode(true); } } } </code></pre>
