Hooks in Action Helpers
Nov 05, 2008 @ 10:34:40

Rob Allen has posted this look at using hooks inside of action helpers (a follow-up from his previous article on action helpers):

Hooks are a feature of action helpers that allow you to automatically run code at certain points in the dispatch cycle. Specially, there are two hook functions available for action helpers: preDispatch and postDispatch. These allow you to ensure that some functionality is always run for each request.

He creates a simple action helper that grabs a random quote from an array and drops it into a property of the helper. By defining a preDispatch method inside of the helper, the HelperBroker knows to pull the method in an execute it immediate before the rest of the actions are executed. A calls to addHelper with the hooks defined is all it takes to glue it together with the execution.
