Need Quick PHP Help with PHP Class + AJAX

Hi there, I have an e-commerce cart in php and it uses a lot of Ajax. I'm trying to access a config table of settings inside the cart so I can use it to hide certain fields if the Admin sets fields to hide.

The settings table is like: ID, Name, Value

I can force the cart to display the settings values but as soon as I change anything on the cart with Ajax it breaks the cart.

I want to fix this right now. I can give you FTP Access, but I would prefer someone to chat with me or screenshare so we can fix it together quickly.

Thanks!!
