Using observers to modify original function

Postby Davidhill on Fri Apr 21, 2017 9:58 am


I want to change the returned value of the get_products() functions from the shopping cart class. I am thinking on building something like an observer class and call the action on NOTIFIER_CART_GET_PRODUCTS_END notifier, I want to modify the returned value $products_array from the observer class so I don't mess up with the shopping cart class code directly.
Is this possible? If so, How do I accomplish this?please help.
I didn't find the right solution from the internet.
