Points per product, sum points at checkout

[Acolytte]

Hi, i need help and solution. I need admin defined points per product and sum them at cart and checkout. I want to offer a discount based on the sum of the points. Its easy end clear. I already have them stored in custom field.


So i have product "Bike"
Bike price is 100$
Bike points is 10 points.

If i add to cart three bikes, i will have 30 points there. After checkout, the points will reset, you cant stack points.


Its really simple but i didnt find any module capable of this, even how to Sum custom fields. Please help me, i am desperate.

(sorry for language, i am not native english)

well, i need to offer a discount based on the points, not cancel the order. is it in the settings? i would like to be able to test it before buying.

also, the points are saved to user. i want them to be reseted after buy. just, if you reach some value, you will get some discount.

Sounds like you may need to build or commission your own plugin.
