PSR-15 middleware to redirect user to correct site language.
- Language detection is based on HTTP headers (browser language) or IP address.
- When the user switches the language, a cookie gets set to save the new language as preferred language.
Example of how the extensions determines the site to redirect to via HTTP headers:
If Accept-Language is
en-US,de-AT it looks for sites with an hreflang of
en-US. If there is no match it then looks for
en. If there is still no match it repeats the same logic with
de-AT and so on.
Install via Extension Manager or composer.
composer require urbantrout/site-language-redirection
Update the GeoIP2 database file for IP address based redirects via CLI or Scheduler.
Create new task of class Excute console commands and set Schedulable Command to sitelanguageredirection:updatedb
Use this option to periodically update your database file.
This step creates a file under
\TYPO3\CMS\Core\Core\Environment::getVarPath() . '/sitelanguageredirection/'with all the geolocation information.
Note: This does not alter your SQL database.
Update the preferred method in your site configuration in the tab Site Language Redirection. Defaults to HTTP headers.
Changing this value to IP address updates
config/sites/<sitename>/config.yamland adds the following line of code:
This feature adds the possibility to define fallback languages. So for instance, if there's no italian version of the website, redirect to english version, and so on.
Site configuration would look like this with optional
SiteLanguageRedirectionMethod: 1 SiteLanguageRedirectionFallbacks: fr: 'en' it: 'en'
