Introducción

Este artículo es parte del tutorial Desarrollo de un Componente MVC para Joomla! 3.2. Te invitamos a leer las partes anteriores del tutorial antes de leer esto. Joomla! 3.2 gestiona idiomas para los componentes en cuatro situaciones diferentes:

la visualización de un componente en el sitio público
la gestión de un componente en el servidor
la gestión de menús en el lado servidor
la instalación de un componente

Joomla! 3.2 uses two different location folder for languages:

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

It depends how the component is installed.

Adding language translation in the public site

With your favourite 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 favourite 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_HEADING_GREETING="Greeting"
COM_HELLOWORLD_HELLOWORLD_HEADING_ID="Id"

Adding language translation when managing the menus in the backend

With your favourite 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!"

Language File Location Options

Starting with version 1.7 there are 2 ways to install language files for an extension. One can use one or the other or a combination of both.

The 1.5 way will install the files in the CORE language folders (ROOT/administrator/language/ and ROOT/language/). Since version 1.6, include the files in a "language" folder installed at the root of the extension.

Therefore an extension can include a language folder with a .sys.ini different from the one installed in the Joomla core language folders. (This last one not being included in that language folder but in root or any other folder not installed.)

This lets us display 2 different descriptions: one from the sys.ini in the "language" folder is used as a message displayed when installation is finished, the other (from the .ini) is used for "normal" operation, that is, when the extension is edited in the back-end. This can be extremely useful when the installation also uses some scripts and requires a different value for the description.

You Should Note!

Therefore, the xml would include since 1.6:

<files>
<[...]
<folder>language</folder>  // This folder HAS to include the right subfolders, i.e. language/en-GB/ ... language/fr-FR/
<filename>whatever</filename>
[...]
</files>

<administration>
    <files folder="admin">
        <[...]
        <folder>language</folder>
        <filename>whatever</filename>
        <[...]
    </files>
</administration>

and/or then (1.5 way):

<languages folder="joomlacorelanguagefolders"> // If using another language folder for cleanliness. (Any folder name will fit.)
<language tag="en-GB">en-GB/en-GB.whatever.ini</language> // or
<language tag="en-GB">en-GB.whatever.ini</language> if no tagged subfolder
<language tag="en-GB">en-GB/en-GB.whatever.sys.ini</language> // or
<language tag="en-GB">en-GB.whatever.sys.ini</language> if no tagged subfolder
</languages>

or simply in ROOT:

<languages>
<language tag="en-GB">en-GB.whatever.ini</language>
<language tag="en-GB">en-GB.whatever.sys.ini</language>
</languages>

Language file used by the installation script during the installation of a component(the first install, not an upgrade) obeys specific rules described in the article, Specification of language files. During the first installation, only the language file included in the component folder (/administrator/components/com_helloworld/language) is used when present. If this file is only provided in the CORE language folder (/administrator/language), no translation occurs. This also applies to KEYs used in the manifest file.

When upgrading or uninstalling the extension (not installing), it is the sys.ini file present in the extension root language folder which will display the result of the installation from the description key/value. Thereafter, if present, the sys.ini as well as the .ini installed in the CORE language folder will have priority over the files present in the root language folder of the extension.

Advantages of Extension "Language" Folder

The other advantage is that this folder can include multiple languages (en-GB always, fr-FR, it-IT, etc.) not requiring the user to install the corresponding language pack. This is handy as they are available if, later on, a user installs the corresponding pack.

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. You can add a menu item of this component using the menu manager in the backend.

helloworld.xml

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="3.2.0" method="upgrade">

		</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).
