So basically I downloaded this website template from here https://w3layouts.com/super-market-e-commerce-online-shopping-flat-bootstrap-responsive-web-template/
Im looking to create my own eccomerce store. How would I go about attaching this website to a database so users can register/login and so i can update the catalogue and recieve orders? Any help would be appreciated..Leaning more towards any guides couldnt seem to find any.
The template you downloaded is just the HTML, CSS, and JavaScript for animations. There are a wide variety of routes you could take in connecting it to a database and adding the user account functionality.
I suggest reading the answers to this question: E-commerce from scratch or not
If you are looking to have an e-commerce site for the purpose of selling items, your best option is to not reinvent the wheel and use a service such as OpenCart.
However, if you want a learning experience, then look up guides on PHP and MySQL. PHP is a server-side scripting language that is used for processing information on the server, which is something you would be doing a lot in an e-commerce application. MySQL is a database application that will store your data. These two technologies, along with the template, will be enough to create a basic e-commerce site. You will also need a web host and a domain.
I suggested PHP and MySQL for their widespread usage and availability of tutorials and guides. There are many more server-side languages and database systems that could be used for this project.
