I need an action hook written for whmcs. It needs to be placed in the hook AfterShoppingCartCheckout. The hook needs to cause an additional flat fee and percent fee to be added to the purchase of my voip products. I need the additional fees to operate the same way taxes currently operate in the order procedure. In the viewable description of each fee's charge I need a link (target=blank) placed to explain why the fee exists. In the php function where you would place the product id tag to cause the charge to only effect that certain product you may leave the generic [product id tag]. Other generics are acceptable in the code as long as discussed prior to completion of project.
The completed action hook needs to be saved as a .php format and delivered to me before completion of pay. This project needs to completed and received by 2/24/11.
I will need more help in customizing whmcs to accomplish all of my company's needs. Appropriate completion of this task can lead to more work.
