**php to SQL posting problem** I recently had a program written in php for e-commerce, but there seems to be a problem with the posting of the cart id to the SQL table. The designer is no longer available for questions, so I had hoped to get some help here. I have a brief knowledge of php, but just cant seem to track the problem down. There are two tables used for the cart: store\_shopping\_cart and store\_shopping\_cart\_items Everything works fine until you try to add an item to the cart. It tries to enter a null value into store\_shopping\_cart\_items for the column shopping\_cart\_id The shopping cart id obviously cannot be null or there could be major confusion between different customers. I know you need more information and to look at the code to give me an answer, but there are many dependent php files (classes.php,common.php, etc.) I didnt want to post them all here and waste a bunch of space… Could some1 contact me and help me track this problem down? I’d like to get the site up and working asap because its a much better design than our current site. Thanks TimmyC [TimmyC@5thavenuebling.com](mailto:TimmyC@5thavenuebling.com)
