Zend View Helpers inheritance

development, php, plugin, zend Comments Off on 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

jQuery plugin: Add2Cart

jquery, plugin 20 Comments »

I added a jQuery plugin called add2cart.

This plugin implements visual effect of adding something to cart (busket). Visually it’s similar to Microsoft Word post-save visual effect, when a gray rectangular of page moves down to the toolbar.

Example of usage:

<input type="button" value="Add to cart"
  onclick="$.add2cart( 'product1_id', 'cart_img_id'  )" />

You can try it out at demo page.
