How to update product price on shopping cart page that dont need override

[phinq1910]

Hi.

 

I have created a module with my custom fields for each product on version 1.6.

Now, i am using override for class Product.php with function getPriceStatic to update product price on Shopping Cart page. (http://localhost/ps1619/order)

 

I want to ask: Is there a way to update product price on Shopping Cart page which have not override above?

 

I know hook hookDisplayShoppingCart but seems it can not update product price because product object is protected

 

Any ideas or solutions.

 

Thank you
