Introduction[edit]
This tutorial is part of the Developing a Model-View-Controller (MVC) Component for Joomla!1.6 tutorial. You are encouraged to read the previous parts of the tutorial before reading this.
[edit]
In the Joomla!1.6 framework, components are executed using menu items. If you go in the menu manager of your Joomla!1.6 installation a HelloWorld menu type does not yet exist. Adding this functionality is easy in Joomla. Simply put a site/views/helloworld/tmpl/default.xml file containing:
site/views/helloworld/tmpl/default.xml
<?xml version="1.0" encoding="utf-8" ?>
<metadata>
<layout title="com_helloworld_HelloWorld_View_Default_Title">
<message>com_helloworld_HelloWorld_View_Default_Desc</message>
</layout>
</metadata>
For the moment the strings won't be translated in the administrator interface. We will see in a later article how translation is performed.
Also modify your helloworld.xml file to indicate a new version:
helloworld.xml
<?xml version="1.0" encoding="utf-8" ?>
<extension type="component" version="1.6.0" method="upgrade">
<name>Hello World!</name>
<creationDate>November 2009</creationDate>
<author>John Doe</author>
<authorEmail>john.doe@example.org</authorEmail>
<authorUrl>http://www.example.org</authorUrl>

<version>0.0.3</version>
<description>Description of the Hello World component ...</description>
<files folder="site">
<filename>index.html</filename>
<filename>helloworld.php</filename>
<filename>controller.php</filename>
<folder>views</folder>
</files>
<administration>
<menu>Hello World!</menu>
<files folder="admin">
<filename>index.html</filename>
<filename>helloworld.php</filename>
</files>
</administration>
</extension>
Packaging the component[edit]
Content of your code directory
- helloworld.xml
- site/index.html
- site/helloworld.php
- site/controller.php
- site/views/index.html
- site/views/helloworld/index.html
- site/views/helloworld/view.html.php
- site/views/helloworld/tmpl/index.html
- site/views/helloworld/tmpl/default.xml
- site/views/helloworld/tmpl/default.php
- admin/index.html
- admin/helloworld.php
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 add a menu item of this component using the menu manager in the backend.
