lib/div in a nutshell


Learn from example extensions in TER:
=====================================

1.) Hello World: apples - A very minimalistic example.
2.) Beginners example: bananas - A workging guestbook. 
3.) Advanced example: efaq - FAQ with many modern features.


Understanding the SPL objects chain:
======================================

SPL (Simple PHP Library) objects have a lot in common with
array. You process your data through the request lifecycle
by "feeding" one SPL object as input to the next:

request  >  object1  >  object2  ...  objectX  >  response 


Understand the class hierarchy:
===============================

All classes inherit from the class tx_lib_object:

                    tx_lib_object
                         |
          ---------------------------------
				  	|            |               |
  tx_lib_controller   tx_lib_model   tx_lib_view
            |            |               |
  yourController      yourModel      yourView	



Understand the "Central Quad":
===============================

 * $controller - The controller object.
 * $context    - Multiple context properties.
 * $parameters - Object containing the request parameters. 
 * $configurations - Object containing all configurations.

 $configurations $context $parameters 
               |   |       |
                $controller
                    |
              $exampleObject   // Represting all "controlled" objects.


Mind 3 central rules: 
=====================

[1] The controller is the central object. It must be set to each
    "controlled" object of your extension, either by constructor
		or by function or directly.

		a.) By the constructor: $exampleObject = new exampleClass($this);	
		b.) BY function: $exampleObject->controller($this); 
		c.) Directly: $exampleObject->controller = $this; 

[2] Each "controlled" object can always access the "Central Quad"
    via the controller:

		a.) $this->controller
		b.) $this->controller->context
		c.) $this->controller->configurations
		d.) $this->controller->parameters

[3] Remember that you can simply extend your controller by 
    registering new actions to it from other extensions.
