Indroduction[edit]

This tutorial is part of the Developing a Model-View-Controller (MVC) Component for Joomla!1.6 tutorial.

The first basic component[edit]

Let's create a Hello World! component.

Public display[edit]

With your favorite files manager and editor, create a file 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).

Administrator management[edit]

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

Hello world administration

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

Packaging an installation zip file[edit]

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.

Delete the components/com_helloworld and administrator/components/com_helloworld directories of your Joomla!1.6 installation.

With your favorite files manager, create a directory (outside of your Joomla!1.6 installation) 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 noticed that the Hello World! component is visible in the administrator site of your Joomla!1.6 installation under the Components menu.
