New to PHP - Basic, simple shopping cart

diablokicks · May 10, 2010

I am fairly new to using php, i have zymic free web hosting and am trying to implement a shopping cart. With zymic they won't let you use "outside connections" so it eliminates shopping cart software. I have come up with some code that looks promising for my needs, however i am having some issues with trying to get the shipping costs set. Let me explain before i give my code. The product is handmade Christmas stockings, so most likely individuals will only be ordering a quantity of 1 for each stocking, but possibly two different stockings. The shopping cart code i have will change the shipping costs if they order qty 2 or more of one product (shipping for first one is 6 dollars, then drops to 2 dollars for each additional stocking), but the shipping will be 6 dollars per each different stocking if they order different stockings. I would like to have the shipping be six dollars for the first initial stocking and increase by 2 dollars for each additional stocking.

I understand shipping 1 is initial for one product and shipping 2 is the incrementing after that. I thought about changing the serial numbers to all the same things, because is still shows them as different products, but if a qty is incorrect, if a user tries to correct it it will drop it from the cart.

SO to summarize, i would like to have an initial charge for the first stocking x amount, and then any other stocking that gets added be y amount. Any help will be greatly appreciated

I am not sure what is considered to be an outside connection, but I have created an e-commerce application that you can use, or just look at the code to see how I made it:

http://bitbucket.org/skunkbad/community-cart/

This is a CodeIgniter application. CodeIgniter is a simple PHP framework. I can't provide lots of free support, but with some effort you should be able to figure out how to use it.
