LanguageAspect implements AspectInterface

The Aspect is usually available as "language" property, and can be used to find out the "overlay"/data retrieval strategy.

"id" (languageId, int)

  • formally known as $TSFE->sys_language_uid
  • the requested language of the current page (frontend)
  • used in menus and links to generate "links in language with this ID"

"contentId" (int)

  • formally known as $TSFE->sys_language_content
  • the language of records to be fetched
  • if empty, "languageId" is used.

"fallbackChain"

  • when "fallback" go with
  • depends what "contentId" value should be set
  • defined in config.sys_language_mode (strict/content_fallback:4,5,stop/ignore?)
  • previously known as $TSFE->sys_language_mode
  • defines "contentId" based on "if the current page is available in this language"
  • "strict"
  • "fallback" if current page is not available, check the "fallbackChain"
  • "fallbackAndIgnore"

"overlayType"

  • defines which way the records should be fetched from ($TSFE->sys_language_contentOL and config.sys_language_overlay)
  • usually you fetch language 0 and -1, then take the "contentId" and "overlay" them
    • here you have two choices 1. "on" if there is no overlay, do not render the default language records ("hideNonTranslated") 2. "mixed" - if there is no overlay, just keep the default language, possibility to have mixed languages - config.sys_language_overlay = 1 3. "off" - do not do overlay, only fetch records available in the current "contentId" (see above), and do not care about overlays or fallbacks - fallbacks could be an option here, actually that is placed on top 4. "includeFloating" - on + includeRecordsWithoutDefaultTranslation

bool

throws
AspectPropertyNotFoundException
Return values
int|string|array<string|int, mixed>

getContentId()

public getLegacyLanguageMode() : string
Return values
string

getLegacyOverlayType()
