This may be too general to have much meaning, but maybe someone can picture the idea if I describe it well.
OSCommerce already has a web interface for customers to order, and a web interface for administration.
What it doesn't have natively is the ability for a third party (a store clerk, a phone operator, etc.) to enter an order on behalf of a customer.
There is an add-on that allows Create Account, and Create Order, and it's installed in some OSC versions, notably OSCMax, but not in all, and to my knowledge, not in the core. Even if it were, there is yet another add-on for OSCommerce called Admin Levels or something similar that determines what certain users/groups can and can't do in the OSCommerce back Admin backend.
It seems much simpler to create the Create Account and Create Order functions in PHPRunner. I am sure that there is some logic in the Shopping Cart Template that has value, like the managing of inventory.
What would be the best/easiest way of keeping the functionality of the Shopping Cart Template, and adding in the PHPR security features, but using the OSCommerce data tables?
Best,
Ken
