In the third part of the series dealing with using Doctrine in your PHP applications, ProDevTips has this third part looking at a method for extending the tool's current functionality.

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).

In the CakePHP blog, The Bakery, there are three new items posted - all three tutorials on different topics:

• 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.
