Developing a Basic Component

Let's create a Hello World! component.

Public display

With your favorite file manager and editor, create a file yoursite/components/com_helloworld/helloworld.php containing 

Hello world

You can test this basic component by putting index.php?option=com_helloworld in your browser address (don't forget to prefix this address with your Joomla!1.6 installation path) after installing this component.

Administrator management

With your favorite file manager and editor, create a file yoursite/administrator/components/com_helloworld/helloworld.php containing 

  1. Hello world administration

You can test this basic component by putting administrator/index.php?option=com_helloworld in your browser address after installing the component.

Packaging an installation zip file

If you have used Joomla before reading this tutorial, you have noticed that extensions are installed using a compressed file containing all the things which are needed for installing and uninstalling them.


With your favorite file manager, create a directory (outside your Joomla!1.6 installation directory) containing

Create a compressed file of this directory or directly download the archive and install it using the extension manager of Joomla!1.6. You can test this basic component by putting index.php?option=com_helloworld or administrator/index.php?option=com_helloworld in your browser address. You can also notice that the Hello World! component is visible in the administrator site of your Joomla!1.6 installation under the Components menu.
