Fun with Zend action helpers

Posted on October 5, 2010

I’ve now started getting back into the swing of things with Zend helpers. They seem to have changed how all this works from how I remember it, so I got to rack my brain a bit to figure this out. I’ll try to make this post as simple as possible. Again, this is for Zend Framework 1.10.

I’m storing my helpers in application/controllers/helpers. The helper I’m writing is called, let’s say, TestHelper. I created a file, TestHelper.php, in that folder. It’s declared as:
class TestHelper extends Zend_Controller_Action_Helper_Abstract
To get it to be included, I had to do the following two things. First, in application.ini, I added:
resources.frontController.actionHelperPaths.TestHelper = APPLICATION_PATH "/controllers/helpers"
Next, in Bootstrap.php, I added:
protected function _initActionHelpers()
Zend_Controller_Action_HelperBroker::addPath('application/controllers/helpers', '');

Now I’ll be completely honest: I don’t fully get why this works. Based on what I’ve read of other people’s experience, you shouldn’t have to put the line in the Bootstrap and also in application.ini, but I did. Also apparently should be able to call this by saying $this->_helper->functionname(), but I have to do $this->_helper->testHelper->functionname(). A little frustrating, but I guess it’s more clear to see exactly which helper is being referenced when you’re debugging.

I’m going to blame the Zend Framework documentation here, but that’s a story for another day.
