* [[Learning Joomla 1.5 Extension Development]]
* [http://docs.joomla.org/User:Jeeradate  Me on Joomla Document web site]

* Module : for page rendering known as "boxes" Module are assigned per menu item and may call component. 
* Component: it is mini application with front and back end.

===For 1.6 up===
* Library

==Joomla Framework==
Joomla เป็น PHP4 ไม่ใช่ PHP5 แต่สามารถพัฒนา Extension ด้วย PHP5 ได้ แต่ต้องคำนึงถึงข้อจำกัดของ PHP4 เวลาทำงานกับ Framework 
===Name Conventions===
We'll start by looking some naming conventions.
* Class names should start with an uppercase letter.
* All named elements should use the camelCase standard.
* Method names should start with a lowercase letter.
* Non-public elements should start with an underscore.
===Class Creation===
Class ทุก Class ที่จะสร้างจะต้อง inherit จาก JOject เท่านั้นเพื่อให้รองรับการทำงานพื้นฐานของ Joomla และต้องไม่ลืมที่จะ Call constructor ของ JOject (Parent class) ด้วยนะครับดังตัวอย่าง
<pre>
/**
  * Some Class which extends JObject
  */
class SomeClass extends JObject
{
     /**
      * Object name
      * @var string
      */
     var $name;
     /**
      * PHP 5 style Constructor
      *
      * @access	 protected
      * @param string name
     */
  function __construct($name)
  {
       $this->name = $name;
       parent::__construct();
  }
}

</pre>
PHP 4 doesn't call constructors of the base class automatically from a constructor of a derived class. It is your responsibility to propagate the call to constructors upstream where appropriate.
===Don't stop with die()===
Reff: http://docs.joomla.org/Do_not_use_die_to_debug

เพราะ Joomla เก็บ State ไว้ใน Database จะต้องจบเป็นลำดับดังนี้
<pre>
echo 'Test';
$mainframe->close();
/*
or use:
jexit();
*/
  
or 

function stop($msg = '')
{
    global $mainframe;
    echo $msg;
    $mainframe->close();
  /*
Alternative:
echo $msg;
jexit();
*/
}


</pre>

==Create Template==
* use NVU 's Joomla extension to create template Joomla V 1.0 only Template Design Guide 
**Download Kompozer/NVU and Joomla extensions for NVU  (No need, it obsolete)
