1. Definition:
Although there are many uses for the session object, one of the most common uses
is to store items for online shopping. When you shop online, you usually browse around the Web
site, occasionally clicking an "Add to Shopping Cart" button to signal that you want to buy
something. When you are done, you click "Check Out" and fill out your billing information. The
session object is a logical place to keep shopping cart data. You can, of course, keep the data
on the client's browser, but it can get pretty cumbersome trying to keep up with the shopping cart
on the client when the user goes from page to page. You can also store the shopping cart in a
database and just keep enough data in the session to make it possible to retrieve the shopping cart
out of the database. If the database is fast enough and you have so many sessions active at one
time that you can't keep all the data in memory, the database might be a better solution. For most
applications, however, the session is the ideal place.
2. Implementation Code(Input Code):
a. Home page containing the gallery of items in the form of thumbnails. Below each
thumbnail display the price and item code for that item. Also there must be a checkbox
displaying the text add to cart below the pries of each item. User can click on multiple
checkboxes to add items in his cart. At the bottom of the page there must be a submit
button which when clicked, control must be redirected to another page
