Developing a Model-View-Controller (MVC) Component for Joomla!1.6 – Part 03

http://docs.joomla.org

Introduction

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.

Adding a menu item type

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 item 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

<extension type="component" version="1.6.0" method="upgrade">     	<name>Hello World!</name>  	<!-- The following elements are optional and free of formatting conttraints -->  	<creationDate>November 2009</creationDate>  	<author>John Doe</author>  	<authorEmail>john.doe@example.org</authorEmail>  	<authorUrl>http://www.example.org</authorUrl>  	<copyright>Copyright Info</copyright>  	<license>License Info</license>  	<!--  The version string is recorded in the components table -->  	<version>0.0.3</version>  	<!-- The description is optional and defaults to the name -->  	<description>Description of the Hello World component ...</description>     	<update> <!-- Runs on update; New in 1.6 -->  		<schemas>  			<schemapath type="mysql">sql/updates/mysql</schemapath>  		</schemas>  	</update>     	<!-- Site Main File Copy Section -->  	<!-- Note the folder attribute: This attribute describes the folder  		to copy FROM in the package to install therefore files copied  		in this section are copied from /site/ in the package -->  	<files folder="site">  		<filename>index.html</filename>  		<filename>helloworld.php</filename>  		<filename>controller.php</filename>  		<folder>views</folder>  	</files>     	<administration>  		<!-- Administration Menu Section -->  		<menu>Hello World!</menu>  		<!-- Administration Main File Copy Section -->  		<!-- Note the folder attribute: This attribute describes the folder  			to copy FROM in the package to install therefore files copied  			in this section are copied from /admin/ in the package -->  		<files folder="admin">  			<!-- Admin Main File Copy Section -->  			<filename>index.html</filename>  			<filename>helloworld.php</filename>  			<!-- SQL files section -->  			<folder>sql</folder>  		</files>  	</administration>     </extension>  

Packaging the component

Content of your code directory

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.
