Hello,

How to pass an arbitrary value to increase order's amount from my custom module ?

I'm trying to make a donation module who allows customer to add arbitrary amount to their orders, I'm able to store this value, but how to add it to the order amount ?

Thanks a lot.

Hi,

I think the simplest   way is  to create a product call "  Donation "   and let customers add it if they want.

You can use a module like crosseling to display that donation in product  details page and in shopping cart summury.

Hello, thank you for your answer

Finally I made a module to do it.

And it works as you said.
