I want to make a language switcher for my site header but I don't want to use the LanguageSupportPageNames module, in this website case I prefer using path siterootpath/services for English and siterootpath/es/services for Spanish, but I can't print the path without $page->localurl() and that function seems to be only available in the LanguageSupportPageNames module .. too if I put siterootpath/es/ in the browser this causes me a 404 error.. How to do this, please?
