以编程方式将产品添加到Virtuemart？

Question

For a customer I am building a Virtuemart 2.0.26d website.

Because of a local law, for each unit of a product that is ordered a fee must be added.

So, when ordering 4 products, the fee must be charged 4 times. By law it is required that the total sum of this fee is visible on the invoice/order confirmation.

I looked at the price rules in Virtuemart, but they don't seem to have an option for this. There is a price modifier after tax, but then the fee is visibile as an negative discount. Something I don't want.

The only solution I came up with is to make a new product for the fee and programmatically add this product for each unit. Can this be done by making a Virtuemart Plugin, or must I change the core for this?

Or are there better solutions for this problem?

Answer 1

You can add extra charge by Taxes & Calculation Rules. create new rules and select tax per product for Type of Arithmetic Operation and select Math Operation + Or +% as per you want to add extra fee per product.

Answer 2

您可以向每个产品添加费用金额的自定义字段，并更改付款插件的代码以将此费用添加到您的订单中。
