I've got a project that is pretty much complete, and functions well. I wrote it myself, but I'm no guru. It's all PHP/MySQL.
The entire shopping cart writes everything to sessions. And on the order summary, I would like to be able to have an extra button next to each item that would add an additional product option... preferably via AJAX (for example, checking off a checkbox would add $1 to the order). I already have a little bit of AJAX implemented, but I just need a little bit more for one or two more things. It is basically just a button that adds a single extra option to any given item, and also the ability to add any additional options to each item (think text box for special order descriptions).
I can show you more details upon request. And I can walk you through the order system so that you can give me additional suggestions to streamline this project.
Effective as of 2-21-08, we had a lot of changes to this project. Instead, we are going to rebuild our ordering system from the ground up.
The ENTIRE system will need to be AJAX, and also have an administration panel for managing the products, store locations, etc. etc.
I'm sorry that I do not have more details about the system yet, but I will post them ASAP so you can adjust your bids accordingly.
Please stay tuned! I will have more information coming soon!
