The concept is actually pretty simple. It involves naming your checkbox as an array and the use of the IN mysql clause. This tutorial aims to give a simple example in the hope that, next time someone asks, I can point them to a tutorial rather than explaining all over again.

They include the database structure, insert statements and the code needed to pull and push the information for the checkboxes.

I simply knew we would need the extension capability that the Mdl class allows for sooner or later, I didn't expect it to be this soon though. The main problem here is saving a many to many relationship straight to the database from the $_POST array, to do that we can extend Doctrine Record with a new function I have named fromArrayExt which adds something extra to the normal fromArray method.

He shows how to extend the classes to create custom handlers for a grouping of checkboxes. The new code automatically handles their submitted values and pushes them directly into the database (with a simple save() call).

• The first is a tutorial that shows how to integrate PHPTAL templates into a Cake application (via a custom PhptalView class)
• Next up is a simple one - the creation of a helper to work with multiple checkboxes in a form .
• Lastly, there's a tutorial that shows an implementation for a counterCache object in a simple application.
