|I am evaluating Foxweb to see if it is appropriate for powering an ecommerce site. |
As with most ecommerce sites, there is a need to keep track of items in a shopping cart. Having read the Foxweb documentation, I can see only three ways of doing this :
Method 1 :
Hold each field of each item in the shopping cart as session variables. For example, if a customer orders one product and the shopping cart needs to store the product code and the price, the session variables will be :
If a customer orders two products, the session variables will be :
If a customer orders three products, the session variables will be :
Method 2 :
Hold each field of each item in the shopping cart in a temporary table ( the temporary table could be named after the session ID, so that each table is unique ).
Method 3 :
Hold each field of each item in the shopping cart in an array, and expand the array as the customer orders more products.
Method 1 seems very clumsy, and I suspect the coding will be very difficult. Method 2 seems capable of dealing with an infinite number of items in the cart, but requires a temporary table to be created and maintained. Method 3 seems to give the benefits of Method 2, without any of the downsides.
a) Am I missing any other methods ?
b) Are my conclusions correct regarding the advantages/disadvantages of each method ?
c) If I were to implement Method 3, how do I go about maintaining a session array ? The Foxweb documentation gives details about single element session variables ( each variable holds one value ), but says nothing about session arrays ( if there is such a thing ).
d) If Method 3 is out of the question, I would have to use Method 2. Has anyone tried this ? Are there any issues that I need to be aware of ?
Many thanks for your replies.
