ch10/nature_readme.txt

The version of our Nature's Source website in the nature
subdirectory of this chapter is the "grand finale" version
of the website we have been developing since the beginning
of the text.

In this final version we have all of the following:
- valid HTML 5 markup for page content structure and valid
  CSS 3 for page content styling and layout
- rotating images on the home page and dropdown menus on
  every page, both achieved with the help of JavaScript
- validation of form data entered by clients, using both
  HTML 5 form control validation and JavaScript validation
- server-side processing with PHP to
  -- display a welcome message that includes the date and
     time, updated every 60 seconds with the help of AJAX
  -- send the results from BMI-form and feedback-form
     submission to the client via e-mail
  -- archive feedback-form data on the server
- PHP mysqli_xx() function connections to a server-side MySQL
  database to register users and permit them to login, to
  retrieve product information for display and sale, thereby
  simulating the processing of online sales transactions
- several SQL scripts that can be used from the MySQL command
  line interface to monitor experimentation with registration
  and online shopping activity via the website's e-store
