Installation

• Download and place the file(s) in a directory called cldr in your extensions/ folder.

• Add the following code at the bottom of your LocalSettings.php:

  wfLoadExtension( 'cldr' );
  

•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.26 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.26 and earlier), instead of wfLoadExtension( 'cldr' );, you need to use:

require_once "$IP/extensions/cldr/cldr.php";

If you download from git, change the file from CLDR to cldr.

Updating data

The CLDR extension comes with data pre-populated in the language files, but if you want to get the latest data from the Unicode Consortium, you'll need to download it from the CLDR site and then run a rebuild script.

Download newest data from CLDR site:

http://www.unicode.org/cldr/repository_access.html

Example (from within the cldr directory):

wget http://www.unicode.org/Public/cldr/latest/core.zip
unzip core.zip -d core
php rebuild.php

Usage and parameters

Language names

CLDR defines the class LanguageNames which has a static method, getNames(). LanguageNames::getNames accepts three parameters:

1. code - the ISO 639 (see here for details) code of the preferred language to return the list in
2. fbMethod - fallback method. Should be set to one of the following:
   • LanguageNames::FALLBACK_NATIVE (default): Missing entries fallback to the native name
   • LanguageNames::FALLBACK_NORMAL: Missing entries fallback through the fallback chain
3. list - which languages to return. Should be set to one of the following:
   • LanguageNames::LIST_MW_SUPPORTED: Only languages that have localization in MediaWiki
   • LanguageNames::LIST_MW (default): All languages that are in Names.php
   • LanguageNames::LIST_MW_AND_CLDR: All languages that are either in MediaWiki or in CLDR

Example

The language names are best access with MediaWiki core functions:

// Japanisch
$name = Language::fetchLanguageName( 'ja', 'de', 'all' );

Country names

CLDR defines the class CountryNames which has a static method, getNames(). CountryNames::getNames accepts one parameter:

1. code - the ISO 639 code of the preferred language to return the list in

Example

The following example sets a variable to the list of all countries in CLDR in French.

if ( is_callable( array( 'CountryNames', 'getNames' ) ) ) {
    $countries = CountryNames::getNames( 'fr' );
}

Currency names

CLDR defines the class CurrencyNames which has a static method, getNames(). CurrencyNames::getNames accepts one parameter:

1. code - the ISO 639 code of the preferred language to return the list in

Example

The following example sets a variable to the list of all currencies in CLDR in German.

if ( is_callable( array( 'CurrencyNames', 'getNames' ) ) ) {
    $currencies = CurrencyNames::getNames( 'de' );
}

CLDR includes a very large number of currencies, including many that are no longer in use.
