Welcome to the home of ValidateThis
ValidateThis is a framework that allows you to define validation rules for your ColdFusion objects in a single place (either an xml file, or in ColdFusion code) and will then generate client-side and server-side validations for you.
Please check out one of the demos, linked to the right, to see the framework in action, as well as a sample xml file.
The framework, as well as all of the demo code, can be downloaded from validatethis.riaforge.org. Near-complete documentation is now available at www.validatethis.org/docs/, and more in-depth discussion can be found at my blog.
The framework itself has been designed to be extremely flexible and extensible. For example:
- The framework ships with a wide variety of built-in validation types. It is easy to add custom validation types without having to touch any existing framework code.
- The framework ships with client-side validations implemented using the jQuery Validation Plugin. It is possible to add other client-side implementations (e.g., prototype, spry, etc.) without touching any of the existing framework code.
- When validation failures occur the framework will return a suitable and meaningful failure message. These default failure messages can easily be overriden by an application developer.
- In addition to failure messages, the framework will return metadata about the validation failure, which can be used to further customize the display of failure information to a user. This can facilitate internationalization.
- The framework can be used in conjunction with any other framework (e.g., Transfer, Reactor, etc.), or no framework at all. As long as you are using a Business Object, you can use the framework to fulfill your validation needs.
- The framework now supports internationalization (i18n).
