The Definitive Guide to Craft Validation for Plugin Developers
The Definitive Guide to Craft Validation for Plugin Developers
A practical guide to unlocking the hidden secrets of validation in Craft CMS.
About the Book
If you're working on a Craft plugin that accepts user input, chances are you'll want to validate that data. Thanks to its Yii underpinnings, Craft includes lots of powerful validation features as standard, but they're not always easy to use or understand.
In an attempt to help us out, Craft adds its own layer of abstraction on top of the Yii validation tools. This makes the syntax a bit more consistent and approachable, but also renders the associated Yii documentation useless. Worse still, the official Craft documentation is currently rather lacking in this area.
That's where this book comes in. It provides a complete guide to validation in Craft 2, all the way from the high-level concepts, right down to the nuts and bolts of implementation.
If you want to know how to implement validation in your Craft plugin as quickly and effectively as possible, you're in the right place.
