Denis, your fix to survey_runtime.js on 02/01/2014 seems to have broken this :)

OK, i try to fix another one with old template ...

I revert or search for a beter way

Token registration form use form#limesurvey too ....

It's not JS ... i send 'lang' now, but same think ...

@tpartner : Can anyone shed some light on why the functionality of the language switcher select was changed?

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=13650

Updated to use existing form (if exist)
Maybe it's better to use allways $_GET for token and register ?
But then need removing existing lang param in URL.

What do you think Tony : better in $_GET or in $_POST ?

Before it's only by url : no get or post, but http://bugs.limesurvey.org/view.php?id=7967

Hi Denis,

The language now switches correctly but, since you are submitting the "register" form, the CAPTCHA warning appears after the switch.

Yes ...

Surely better in $_GET then. But if you have already a /lang/fr in URL : getParam don't get the good param.

But we can have lang-fr or /lang/fr or &lang=fr or ?lang=fr

Did you have an idea to remove it in JS ?

PS: another alternative is to add a data-submit="UrlOfSurveyController" in the select or in the button.
Then we can add directly it to this url.

Got it, add to test with preview to see if it's OK.

Tony : 2nd fix : working in preview/token/register and in survey even if {LANGUAGECHANGER} is not at the good place.

You got it :)

JS needed for change language in token and register.
