Building An Extensible Form Validator Class - Closing Time (
Page 12 of 12 )
And
that's about all for the moment. In this article, you expanded your knowledge of
PHP's OOP capabilities by actually using all that theory to build something
useful - a form validation widget which can be used to verify the data entered
into an online form, and provide a way for you to take action in case the data
entered by the user does not met your expectations.
If you're a
stressed-out Web developer working on a Web site, a Web application or an
embedded system, you might find this object a handy tool in your next
development effort. If you're a novice programmer struggling to understand how
OOP can make your life easier, I hope this article offered some pointers, as
well as some illustration of how object-oriented programming works. And if you
don't fit into either of those categories - well, I hope you found it
interesting and informative, anyway.
See you soon! Note: All examples in
this article have been tested on Linux/i586 with Apache 1.3.20 and PHP 4.1.1.
Examples are illustrative only, and are not meant for a production environment.
