We're going to take what was put together in the last 3 videos and now include some server-side validation that will appear asynchronously. This is an example of using Zend_Form as a validation tool via JSON.
Here's the last three videos if you need to catch up:
- Encapsulating Business Rules with Zend_Validate
- Preparing Custom Elements for Zend Validators
- Writing Composite Zend_Form Elements
If you'd like to follow along with this most recent screencast, though, you can download the source directly.
