Chapter 6. Forms

Most CGI programs use HTML forms to gather user input. Forms are comprised of one or more text-input boxes, clickable radio buttons, multiple-choice checkboxes, and even pull-down menus and clickable images, all placed inside the <form> tag. Within a form, you may also put regular body content, including text and images. The JavaScript event handlers can be used in various form elements as well, providing a number of effects such as testing and verifying form contents.
