I found this online. I don’t want to use session to save it locally and want to change it. Submit the order into the database so that you can see the items in the shopping cart on any computer. I am a novice and learn by myself. I don’t want to use a framework. I can use PHP AJAX MYSQL CSS JAVASCRIPT JQUERY with pure basic code. Can anyone trouble me? Or the teacher can help me implement this function
