Magento Content management System is an easy to use and flexible eCommerce CMS. You can customize the settings for your online store in simple steps. This blog post will cover one such customization for Magento store managers – how to programmatically Add Product to Cart with Price Change.

How to Programmatically Add Product to Cart with Price Change in Magento

After digging a bit into Magento’s core code, I found that you need to use $item->getProduct()->setIsSuperMode(true) in order to make $item->setCustomPrice() and $item->setOriginalPrice()work.

Here is some sample code you can use within an Observer that listens for the checkout_cart_product_add_after or checkout_cart_update_items_after events. The code is logically the same except checkout_cart_product_add_after is called for only one item and checkout_cart_update_items_after is called for all items in the cart. This code is separated/duplicated into 2 methods only as an example.

Use the following code to programmatically add product to cart with price change (put it into Observe.php):

Event: checkout_cart_product_add_after

 Event: checkout_cart_update_items_after

This will surely help you to programmatically add product to cart with price change. But, if you unsuccessfully in changing it, then request a quote. Our Magento team will provide you expert guidance for detecting and solving the problems.
