I’ve been using qForms for form validation for a long time now. I was fortunate to have a fellow developer tell me about it and have used it ever since. I thought I’d pass the information on to you.
You can view an example of how I use it in the most basic way:

Integrating it within your application framework is trivial yet there are so many validation methods to choose from such as email, integar, numeric, alphanumeric, required, length etc.
This of course does not mean you don’t have to validate on the serverside before writing to your DB of choice. You have to assume that someone will turn off javascript and thus you must validate on the backend. If you don’t, you will expose your database to all kinds of risky scenarios.
I suggest that if you find it useful, you should consider contributing to the ongoing effort of improving it. Click on the “PayPal” link on their site here: http://pengoworks.com/index.cfm?action=get:qforms
Enjoy!
