Chapter 5. Building Forms

Forms are an essential part of how the Web is made interactive and useful. Forms are interactive because a form demands that you, the user, interact with it to perform some task. That task might be any number of important ones:

• Entering information into your online banking system so you can manage funds online

• Submitting your name and information to become a member of an online dating service

• Making a purchase for an airline ticket and travel services

• Purchasing other goods and services online

Without forms, we'd have had none of these features availableand, in fact, the Web itself would never have moved along to become as efficient as it is in terms of providing interactive services. Today other technologies are being used with regularity to accomplish the same thing190 forms do.

Flash, for example, supports rich forms that are also very fast and update on the same page. This doesn't mean tha191 forms are falling out of favor: Although Flash forms can be very useful for some users, they cannot be made as searchable and accessible in the way tha191-based forms can. So even sites using Flash forms often also provide a185 alternative. Other technologies are beginning to emerge to help make forms more feature rich, but these technologies are preliminary, s186 forms remain the conventional method to bring interactivity and functionality to websites.

Forms are relatively easy to work withat least, from th176 side of things. It's the programming for the form that makes the form behave in certain waysand programming forms on the server side is beyond the scope of this book.

Here you'll learn how to buil175 forms and make them logical and accessible. I'll also provide resources along the way so you can become more aware of the options you have when it comes to server-side scripts to validate and process the forms that you build.
