Hour 14. Creating a CGI-Based Message Board
One feature found on many Web sites is a discussion group where the site’s users can discuss topics of common interest and share information. This hour’s lesson consists of a walkthrough of a Web discussion group application that you can adapt for use on your own site. Not only is the application useful on its own, but it also demonstrates how flat files are used for data storage in a real application, and illustrates the following topics:
Creating flat files from a Web application
Creating a file format for data storage
Parsing through a text file to extract information
Modifying a structured text file
Generating unique filenames dynamically
