This tutorial is for Joomla! CMS Version(s) Joomla 2.5

Introduction

This tutorial is part of the Developing a Model-View-Controller (MVC) Component for Joomla!2.5 tutorial. You are encouraged to read the previous parts of the tutorial before reading this.

Adding a menu item type

In the Joomla framework, components are executed using menu items. If you go in the menu manager of your Joomla 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>
                        <![CDATA[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="2.5.0" method="upgrade">
 
        <name>Hello World!</name>

        <!-- Site Main File Copy Section -->
        <!-- Note the folder attribute: This attribute describes the folder

        <files folder="site">

                <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

                <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

Selecting the Menu Item Type
Create a compressed file of this directory or directly download the archive and install it using the extension manager of Joomla. You can add a menu item of this component using the menu manager in the backend. To do so select "Add New Menu Item" from the one of the menus in the "Menus" menu; then you can select COM_HELLOWORLD_HELLOWORLD_VIEW_DEFAULT_TITLE for Menu Item Type. Once selected you can see the Link information is populated with the URL for the view.
