Hour 22. Basic Forms

What You'll Learn in This Hour:

• How to process basic forms in Perl CGI programs

• How to debug CGI forms

• How to write safer CGI programs

While surfing the Web, you've undoubtedly filled out a few HTML forms. HTML forms, such as email web forms, shopping carts, guestbooks, online auction forms, mailing list subscriptions, and order forms, are used to collect information, such as login information, and even web site preference settings from the web browser's user .

When the user clicks the submit button on those forms, what happens? Almost always, the data from that form is passed to a CGI program. In this hour, you'll learn how to take data from a form and manipulate it in your CGI programs.
