PHP - Avactis Shopping Cart Programmer - Experienced with this cart We are in need of a PHP Developer with Experience with the complex functions of the Avactis Shopping Cart. We are PHP Developers and we are having a tough time with this system. Task 1: file affected: system: avactis-system/modules/checkout/actions/[login to view URL] line: 106 template: [login to view URL] On checkout there is a field we added that if its not valid the system takes you back to the page that the field is in, However we want the system to give the user an alert box before the redirect. ( this sounds simple but we have been trying to make this work for 2 days now ) Task 2: file affected: {cant find it maybe you can} On [login to view URL] post back there is a field that we passed called TawPagID, we want you to insert this into an auto increment table we created. Please ONLY BID if you have worked with this system and you know it wellwe have a deadline and wish to complete this ASAP. thanks
