A very interesting project where we were hired to build a highly customised language switcher combining WPML with Google Translate.
The client is running the site in 7 languages which form the main markets. On top of that it also wants to attract clients from other countries, but those 14 markets do not (yet) justify the budget to translate the entire site in that language.
Therefore the idea was to use Google Translate for those 14 languages and add them to the WPML language selector.
With a creative solution we managed to add the Google languages after the WPML languages and by giving them a class, an icon could be added to show the visitor that those languages are in fact machine translations.
