I’m glad you have decided to make form validation easy, that’s how it’s supposed to be! With this script you are able to validate any sort of input coming from any type of array data source ($_POST, $_GET, array).
The script can be plugged in with your existing html form code without drastically changing the source code. The script doesn’t just validate data it populates form input fields, checkboxes and select lists if a default value has been set and when a form is posted and returned to the user. This way no information has to be typed twice when a form is not valid on the first try.
Predefined validation rules such as required, format, min and max comes built into the script but how you want to validate each and every form field is totally up to you. With custom functions you are able to hook up into the script and supply your own validation rules and error messages.
