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.

Joomla!1.6 manages languages for components in four different situations:

  • displaying a component in the public site
  • managing a component in the backend
  • managing menus in the backend
  • installing a component (new in 1.6)

Joomla!1.6 uses two different location folder for languages:

  • one in administrator/language or language
  • one in the component folder (administrator/component/*component*/language or component/*component*/language)

It depends how the component is installed.

Adding language translation in the public site

With your favorite file manager and editor, put a file site/language/en-GB/en-GB.com_helloworld.ini. This file will contain translation for the public part. For the moment, this file is empty

site/language/en-GB/en-GB.com_helloworld.ini

 

For the moment, there are no translations strings in this file.

Adding language translation when managing the component

With your favorite file manager and editor, put a file admin/language/en-GB/en-GB.com_helloworld.ini. This file will contain translation for the backend part.

admin/language/en-GB/en-GB.com_helloworld.ini

COM_HELLOWORLD_HELLOWORLD_FIELD_GREETING_DESC="This message will be displayed"
COM_HELLOWORLD_HELLOWORLD_FIELD_GREETING_LABEL="Message"
COM_HELLOWORLD_HELLOWORLD_HEADING_GREETING="Greeting"
COM_HELLOWORLD_HELLOWORLD_HEADING_ID="Id"

Adding language translation when managing the menus in the backend

With your favorite file manager and editor, put a file admin/language/en-GB/en-GB.com_helloworld.sys.ini. This file will contain translation for the backend part.

admin/language/en-GB/en-GB.com_helloworld.sys.ini

COM_HELLOWORLD="Hello World!"
COM_HELLOWORLD_DESCRIPTION="This is the Hello World description"
COM_HELLOWORLD_HELLOWORLD_VIEW_DEFAULT_TITLE="Hello World"
COM_HELLOWORLD_HELLOWORLD_VIEW_DEFAULT_DESC="This view displays a selected message"
COM_HELLOWORLD_MENU="Hello World!"

Adding translation when installing the component

With your favorite file manager and editor, put a file language/en-GB/en-GB.ini. This file will contain translation for the install.

language/en-GB/en-GB.ini

COM_HELLOWORLD="Hello World!"
COM_HELLOWORLD_DESCRIPTION="This is the Hello World description"

The COM_HELLOWORLD_DESCRIPTION can be used in the helloworld.xml file

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.

helloworld.xml

                </languages>
        </administration>
 
</extension>

In this helloworld.xml file, languages are installed in:

  • administrator/language for the admin part (look at the xml languages tag)
  • components/com_helloworld/language for the site part (there are no xml languages tag in the site part of the xml description file, but the language folder is included)
