Hi,
Many many thanks for the great set of responses. This helps to clarify
nicely. I've created a custom action helper, integrated it into the site,
and confirmed the framework is able to recognize and execute it. However
there remains one perplexing matter: how do I initialize this action helper
in a way that makes several of its variables automatically available to all
controllers? The idea is to completely remove all redundant code from the
various controllers' init() methods, thereby making the variables within the
controller available in each controller's $this context.
Based on your varied responses regarding the action helper, surely there's
some way to do this? The goal is to use this action helper to make the
following variables automatically available to all controllers:
$this->config = Zend_Registry::get('config');
$this->cache = Zend_Registry::get('cache');
$this->db = Zend_Registry::get('db');
Thanks for all of your help!
