Language switcher in Symfony stack is compatible with eZ Publish 5.3 / 2014.05
A content can be translated in several languages. Those languages are configured in the system and exposed in SiteAccesses via a prioritized list of languages:
When visiting a content, it may be useful to let the user switch from one translation to another, more appropriate to him. This is precisely the goal of the language switcher.
Configuration: explicit translation SiteAccesses
Configuration is not mandatory, but can help to distinguish which SiteAccesses can be considered translation SiteAccesses.
Note: Top prioritized language is always used for as the SiteAccess language reference (e.g.
fre SiteAccess in the example above).
If several translation SiteAccesses share the same language reference, the first declared SiteAccess always wins.
Configuration: more complex translation setup
There are some cases where your SiteAccesses share settings (repository, content settings...), but you don't want all of them to share the same
translation_siteaccesses setting. This can be the case when you use SiteAccesses for mobile.
Solution is as easy as defining new groups:
Configuration: using implicit related SiteAccesses
translation_siteaccesses setting is not provided, implicit related SiteAccesses will be used instead. SiteAccesses are considered related if they share:
- The same repository
- The same root location Id (see Multisite feature)
In a template
To generate a language switch link, you need to generate the
RouteReference, with the
language parameter. This can easily be done with
ez_route() Twig function:
You can also omit the route, in this case, the current route will be used (i.e. switch the current page):
When using sub-requests, you lose the context of the master request (e.g. current route, current location...). This is because sub-requests can be displayed separately, with ESI or Hinclude.
If you want to render language switch links in a sub-request with a correct
RouteReference, you must pass it as an argument to your sub-controller from the master request.
ezpublish.translationSiteAccess( language )returns the SiteAccess name for provided language (or
nullif it cannot be found)
ezpublish.availableLanguages()returns the list of available languages.
You can easily generate language switch links from PHP too, with the
You can also retrieve all available languages with the
