The Bakery Everything CakePHP

This component adds a few validation options to the already wonderful CakePHP form validation. These features include:
Confirm - Checks two or more fields to make sure they are an exact match (designed for password creation).
Unique - Checks to make sure that a field is not already present in the database (ie email, username, etc).
More output options - There are three output options - unordered list in a div tag of your choice, a JavaScript alert, or just the array to do what you want with it.
Error Class - It has the option to change the CSS class of the label tags for the invalid fields.

The component uses Ajax to be able to validate without refreshing the page. It also relies heavily on the "Standard" CakePHP naming conventions for easier integration.

Here's a way to perform a cleaner and better way of validating your model data in CakePHP.

Automates several aspects of multi-page forms including data persistence, form preparation, wizard resetting (manual and automatic), and wizard navigation (including jumping between steps) while maintaining flexibility with custom validation and completion callbacks.
