Zend View Helpers inheritance

It’s handy to use View Helpers in Zend FW driven project. For example, you want to make an in-place tracker (e.g. Google Analytics) — you create a helper class My_View_Helper_Tracker inherited from Zend_View_Helper, Zend finds its automatically and then you are free to use your helper method:

echo $this->tracker( $trackerID );

The question is what you gonna do if you want a base class for a family of trackers?

It’s not so obvoius due to naming conventions.

Let’s say you want 2 kinds of trackers: Google Analytics and Euroads.

1. You create such files structure:

library
 - My
   - View
    - Helper
      - Tracker
        Abstract.php
        - Google
          Page.php
        - Euroads
          Owner.php
          Guest.php

2. You name your classes as:

• My_View_Helper_Tracker_Euroads_Guest (extends My_View_Helper_Tracker_Abstract)
• … so on …

3. Class methods are:

public function tracker_euroads_guest(...) ...

4. And the trickiest part: the helper call:

echo $this->tracker_Euroads_Guest
