8. Extension
This project was created A fairly simple PHP shopping cart system. We can also make many improvements and enhancements to it:# In a real online store, some order recording and implementation system may have to be established - in this system , the user cannot see the orders that have been booked.
Customers want to be able to check on the status of their order without having to contact us. Users should have a means of authentication that enables them to view their previous orders and also allow them to closely tie actions to their personal circumstances. It is also more convenient for us to collect some user habit information.
Pictures of the book can be transferred to the site's images directory via a service such as FTP and given an appropriate name. You can upload files to the image insertion page to make this operation easier.
You can add user login, personalized settings and book recommendations, online reviews, membership systems, inventory level checks, etc. There are so many features that can be added.
