Introduction

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

The first basic component

Let's create a Hello World! component.

Public display

With your favorite file manager and editor, create a file site/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

With your favorite file manager and editor, create a file admin/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

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

• helloworld.xml
• site/helloworld.php
• site/index.html
• admin/helloworld.php
• admin/index.html

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.
