DevShed:
Creating a Validation Helper Class
August 17, 2009 @ 15:10:31

DevShed has continued their series looking at helpers in PHP5 applications with this new tutorial about creating a simple validation helper to ensure inputted data is as it should be.

In this fifth part of the series I plan to build a class that will be responsible for validating input data, either supplied by users or from a different source. In this specific project, this validation helper will make use of the PHP filter extension to perform the pertinent checking processes, but it can be easily adapted to use custom methods as well.

Their example code sets up two methods for validating integers and floats against the values given. It uses the filter extension to run the check.
