Partners:

You may complete this assignment individually or with one partner.  Both partners must understand all aspects of the code produced as I will ask questions about your code when it is demoed to me.

Overview:

The purpose of this assignment is to bring together many of the concepts covered during this course including HTML, JavaScript and Perl.

Your Task:

Create a mini-online store.  You can sell any products, just find some pictures on the internet of the products you wish to sell.  Here is what your online store must be able to do:

HTML (with JavaScript) Pages...

• Product pages
  • Display several products with a picture, description and price for each.
  • Allow the user to select products and quantities of these products to order
    • this information is keep in a cookie for use on the "order total page"
• Order total page
  • Displays a summary of their order including taxes and final price
    • product quantities obtained from cookie
    • taxes and total calculated using JavaScript
  • Asks user if they wish to proceed with purchase, if they select yes, go to the customer info page
• Repeat customer page
  • Asks user if they have ever purchased before from your store before
    • if yes, they fill in a login name and password
      • send name and password over a secure connection to the server to look up in a user name and password file (text file which must be able to contain several users and passwords, details below...)
    • if no, they click a button to proceed to Customer information page
• Customer information page
  • If user provides incorrect name and password, or if they have never ordered before
    • display form to allow user to enter information for shipping and billing
      • form includes: first name, last name, full address, phone number, credit card number and expiry date
  • If user has provided a correct name and password from previous page
    • display form with all user information filled in from a file containing user information
    • this information must be sent to the browser using a secure connection
  • When user clicks submit, you must
    • verify that all information has been entered using JavaScript before the form is sent
    • if form is complete, send this information to the server over a secure connection
• Confirmation page
  • server send back over secure connection a unique receipt number and note assuring the customer that their order was received

Text Files

• Pervious customer information
  • holds names, passwords, and all user information for several users

Perl Scripts

• Password verification and customer information retrieval script
  • receives a name and password, checks that it is valid, if it is, sends back all customer information for this customer as stored on the server for the customer information page
• Order receiving and confirmation script
  • sends a confirmation number to the user
  • ideally this script should write the order information into an order text file as well as update the customer information file, however, since we can't write from a Perl script to a file on the server, we will not implement either of these features

Mark Breakdown:

• Product pages allow user to select among several products [1 mark]
• Product selections keep in cookie and are displayed on the order total page [1 mark]
• Order total page correctly calculates taxes and totals using JavaScript [1 mark]
• Repeat customer page sends name and password securely to password verification and customer information retrieval script [1 mark]
• Password verification and customer information retrieval script looks up name and password, and send back all relevant information to be displayed in the customer information page form. [2 marks]
• Customer information page allows all info to be entered and sent securely to the order receiving and confirmation script [1 mark]
• Order receiving and confirmation script receives all info successfully and sends back receipt message. [1 mark]
• Pages are well designed with consistent attractive look (a style sheet would be nice, but is not required) [1 mark]

Demo For Marks:

You may demo your work to me during any CST8127 lab between now and December 6th.  No assignments will be demoed after December 6th.  If you have completed this lab with a partner, both partners must be present at the time of the demo.
