This documentation is transcluded from Template:GetFallback0/doc.

Test for the presence of a fallback subpage within a specified template (when the non-fallback language specified in parameter does not provide some resource), and returns its code.

If no subpage is found matching the fallback languages returned by either {{GetFallback}} or {{GetFallback2}}, then this template will return the default content language code of the project (as reported by {{CONTENTLANGUAGE}}).


{{GetFallback0 |1= |2= }}

Fallback languages are determined in {{GetFallback}} and {{GetFallback2}}. When this template is used, it cannot test that the subpage discovered is a redirect : no fallback language determined in {{GetFallback}} and {{GetFallback2}} should be redirects, otherwise a template inclusion loop may occur, if a template uses this template (or {{Fallback}}) to retrieve an alternate translation for missing resources that it does not define itself.

For example the fallback of "pt-br" should be "pt", but there must not be any redirect from the fallback subpage "/pt" to "/pt-br" in the rendered page (but the reverse is possible to avoid using this template). The same is true for a subpage "/zh" that must not be redirected to "/zh-hans" or "/zh-hant" (but here also it is safe to create a redirect from "/zh-hans" and/or "/zh-hant" to "/zh").
