This is a core PHP project about e-commerce. The client needs a website to showcase their surgical products to the world. He listed all his surgical products on the site by category. Anyone can visit the site, browse the categories, view the product, add the query to the cart, and send the query to the admins. This site has a lot of bugs. All forms show errors on submission so the Client asked me to debug the problem and solve the issue. Alhamdulillah I resolved..
