CGI Programming 101

CGI Programming 101 will show you how to add guestbooks, page counters, shopping carts and other interactive elements to your website. CGI programming is easy to learn; if you know HTML, you can learn CGI. You don't need any prior programming experience.

CGI Tutorial
CGI is the Common Gateway Interface which allows you to create Web pages on the fly based on information from buttons, checkboxes, text input and so on. The pages can be images, sounds, text and indeed everything else transferable by the Web. They can even be references to other Web pages. In this tutorial we concentrate on creating HTML documents (rather than images and sounds) but the principles transfer readily to other formats. This should provide a good start to cope with the more comprehensive documentation elsewhere.

CGI Made Really Easy

This primer focuses on writing CGI scripts to process HTML forms on the Web. It skips some details, but can bring you up to speed fast (literally an hour or less), and covers 90% of real-world situations.

The Common Gateway Interface

Once you have a basic idea of what CGI is and what you can use it for, you should read this primer which will help you get started writing your own gateways. After reading this document, you should have an overall idea of what a CGI program needs to do to function.
