We have a supplier that gives us a txt file with the wholesale price of their products. Some of their products have a unit price but this supplier is selling them to us by using a minimum quantity from this certain products.
So what i need to be done in my modified zen cart [url removed, login to view] store is to add a new database field and also add it in the admin/[url removed, login to view] page so the the administrator that adds a product to our store would have a new field in the [url removed, login to view] page to type in the minimum quantity that a customer can purchase from us (that should be similar to our supplier). When ever someone adds any of these products in his shopping cart then even if he adds one item in their cart should be added the minimum quantity of these products. And a message should appear (like the function that zen cart has for the out of stock items) to notify the customer that this products has a minimum quantity for its order.
The same procedure should happen if someone alters the quantity of these items in his shopping cart.
For example lets say a product sunglasses has a minimum quantity 20 from our supplier
When our administrator adds this product to our store he also fills the minimum quantity field with 20
If a customer adds this product to his cart then a message should appear along with his shopping cart (like with the out of stock items) and this message should state that you can order either the minimum quantity for this product that is 20 or you have to order multiple of the minimum quantity (i mean 40, 60, 80 ...)
