-The site is finished and satisfied all the requirements.
-"my_Category" table shows the category of the products
-"my_Product" table shows the products available in a category including the product name, price, availability etc.
-All the links have been updated and functioning as required.
--Made some changes in the Site Map structure than the actual website.
-Added a new feature in the quote that changes in every refresh.
-Buying a product asks for login first.
-All the other functionalities works as required.
All the features and functionalities are added based on the requirements. However, shopping cart is not fetching the 
product data from the database. Therefore, when clicking "Buy this item" from the catalog, it doesn't show the specific 
prouducts from the my_Product table ($query = "SELECT * FROM my_Product WHERE product_id = '$productID'";) with this query. 
Instead it shows, some error. Therefore, I have kept the query to show an specific product from the database. Although, 
checkout shows empty items like the way it should behave based on the situation and refer back to the catagory as there are 
no products to purchase.
