Building E-Commerce Shopping Cart Website in PHP & MySQL

Here I'm going to build a Shopping Cart with these features

In FrontEnd Displaying Products and home page and displaying products with categories. Next adding to products cart from home page category page and adding product to cart in multiple quantity from single product page.

Next is displaying products added to cart in cart page and also in drop-down menu with checkout link.

While user goes to checkout page after adding products to cart. We will check user logged in or not?
If user logged in we will allow him to checkout page or else he will be prompted to login or register.
If he is a new user, he should register. If he is not a new user, he can login with his login credentials.

In checkout page, if the user already has billing details. It will be displayed or else user will be prompted to enter billing details.

After that user can choose the payment method and accept the terms his order will be placed. For now, I'm using only Cash On Delivery method.

If we use payment gateways, user will be redirected to payment gateway. If he pays we will store transaction id and other information from payment gateway provider into our database.

Customer can submit reviews to product, customer can submit only one review per product.

Customer can cancel his order. Also customer can update his or her address from my account page.

Customer can check all the orders from my account page. And also view single orders from single order view page.

Wishlist for customer to add products to wishlist and remove products from wishlist.

In Back End Admin Area, Admin User will be able to login and add, edit & delete products. And also admin user can check the orders. Go through the list of customers and go through all the reviews submitted by customers.

Order Processing from backend, admin can process the order in 4 different stages one is Order Placed, Order In Progress, Order Dispatched, and Order Delivered.

A lot more features are included.
