Introduction[edit]

This tutorial is part of the Developing a MVC Component for Joomla!3.2 tutorial. You are encouraged to read the previous parts of the tutorial before reading this.

Abstract[edit]

Generally speaking, this article describes how to get a link on your joomla page to open a specific page of your component. This gets simply done by adding an xml file to your specific page into your view folder.

E.g.

site/views/helloworld/tmpl/

Contains your view page default.php that we want to open.

A file default.xml is placed next to this file with some xml. This makes joomla able to recognize the view file default.php as a menu item.

Adding a menu item type[edit]

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="3.2.0" method="upgrade">

	<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

		<files folder="admin">
			<!-- Admin Main File Copy Section -->
			<filename>index.html</filename>
			<filename>helloworld.php</filename>
			<!-- SQL files section -->
			<folder>sql</folder>
		</files>
	</administration>

Packaging the component[edit]

Content of your code directory 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.
