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