FormValidator

It is absolutely essential that you validate data submitted through forms on your web site. Forms are the wild-wild-west. Without forms validation, it is not a question of if you will be hacked, it is a question of when.

I have been using FormValidator for years, updating it regularly with new exploits as they become known. FormValidator has some unique rules, and some that are absolute must-have. Check out the Rules section for an overview.
