Updating price in product page with javascript

[lightdown]

Hello,

I'm trying to develop a module to calculate the product price from a product tables, and my problem is How can I update the product price in real time? I know how to update the price in our_price_display span, but, when I click in add to cart, the product is added to the cart with the original price. 

Any idea ?

 

Thanks

You have a long way to get that.

 

Is not difficult but is not that simple like just change the price you need to check the Cart class and learn how these work, after that you are going to add hack to keep your selection for the whole process

And that is the point: "keep your selection for the whole process". Is there any documentation about that? Where is stored all the information about the product? In Cookie or other global var?

I have develop some modules and in the BO all seem to be is more easy (access to cookie, global vars, product object, etc), but in front office...how can i do that?

Thanks

You need to work with the overriding  of the cart, and use the cart tables for keep info

 

you can get the cart id using the cookies and look on the cart_product table

I think you are right. I'll try that solution.

Thanks!
