Adding Languages

The Site Management > Sites module lets you specify which languages are active for your site, which languages are available, and how they should behave. New languages for a site can also be configured in this module.

When the backend shows the list of available languages, the list of languages is limited to the languages defined by the sites module. For instance, the languages are used in the page module language selector, when editing records or in the list module.

The language management provides the ability to hide a language on the frontend while allowing it on the backend. This enables editors to start translating pages without them being directly live.

Note

In case no site configuration has been created for a tree, all configured languages are displayed. In this case the page TSconfig options mod.SHARED.defaultLanguageFlag, mod.SHARED.defaultLanguageLabel and mod.SHARED.disableLanguages settings are also considered - those are obsolete, if a site configuration exists.

Language fallbacks can be configured for any language except the default one. A language fallback means that if content is not available in the current language, the content is displayed in the fallback language. This may include multiple fallback levels - for example, "Modern Chinese" might fall back to "Chinese (Traditional)", which in turn may fallback to "English". All languages can be configured separately, so you can specify different fallback chains and behaviors for each language.

Example of a language configuration (excerpt):

config/sites/<some_site>/config.yaml | typo3conf/sites/<some_site>/config.yaml

languages:
  - languageId: 0
    title: English
    navigationTitle: ''
    base: /
    locale: en_GB.UTF-8
    iso-639-1: en
    hreflang: en-US
    direction: ltr
    typo3Language: default
    flag: gb

Configuration properties

enabled

Type: bool
Example: true

Defines, if the language is visible on the frontend. Editors in the TYPO3 backend will still be able to translate content for the language.

languageId

Type: integer
Example: 1

For the default/main language of the given site, use value 0. For additional languages use a number greater than 0. Every site should have at last one language configured - with languageId: 0.

Attention

Once pages, content or records are created in a specific language, the languageId must not be changed anymore.

title

Type: string
Example: English

The internal human-readable name for this language.

websiteTitle

Type: string
Example: My custom very British title

Overrides the global website title for this language.

navigationTitle

Type: string
Example: British

Optional navigation title which is used in HMENU.special = language.

base

Type: string / URL
Example: /uk/

The language base accepts either a URL or a path segment like /en/.

baseVariants

Type: array

Allows different base URLs for the same language. They follow the same syntax as the base variants on the root level of the site config and they get active, if the condition matches.

Example:

baseVariants:
  -
    base: 'https://example.localhost/'
    condition: 'applicationContext == "Development"'
  -
    base: 'https://staging.example.com/'
    condition: 'applicationContext == "Production/Sydney"'
  -
    base: 'https://testing.example.com/'
    condition: 'applicationContext == "Testing/Paris"'

locale

Type: string / locale
Example: en_GB

The locale to use for this language. For example, it is used during frontend rendering. That locale needs to be installed on the server. In a Linux environment, you can see installed locales with locale -a. Multiple fallback locales can be set as a comma-separated list. TYPO3 will then iterate through the locales from left to right until it finds a locale, that is installed on the server.

iso-639-1

Type: string
Example: en

The two-letter code for the language according to ISO-639 nomenclature.

hreflang

Type: string
Example: en-GB

The frontend language for hreflang and lang tags.

direction

Type: string
Example: ltr

The text direction for content in this language (left-to-right or right-to-left).

typo3Language

Type: string
Example: en

Language identifier to use in TYPO3 XLIFF files.

flag

Type: string
Example: gb

The flag identifier. For example, the flag is displayed in the backend page module.

fallbackType

Type: string
Example: strict

The language fallback mode, one of:

fallback

Fall back to another language, if the record does not exist in the requested language. Do overlays and keep the ones that are not translated.

It behaves like the old config.sys_language_overlay = 1. Keep the ones that are only available in default language.

strict

Same as fallback but removes the records that are not translated.

If there is no overlay, do not render the default language records, it behaves like the old hideNonTranslated, and include records without default translation.

free

Fall back to another language, if the record does not exist in the requested language. But always fetch only records of this specific (available) language.

It behaves like old config.sys_language_overlay = 0.

fallbacks

Type: comma-separated list of language IDs
Example: 1,0

The list of fallback languages. If none has a matching translation, a "pageNotFound" is thrown.
