Dear Users,
here is what i do: in a template i use a href on a picture.

<a href="internal-page-name/"><img src="path-to-the-image" width="xx" height="xx" alt="alternate-title" title="title" /></a>

When i click on the picture i am always forwarded to the internal-page-name with the configured standard language.
I couldn't find a way to fix this problem.

Can you give an example of where the page should go for the other languages?

I'm switching languages by adding the local to the URL e.g. http://www.silverstripe.org/?locale=fr_FR

If i do not add a locale in the href, the href will forward to the default locale. I want the link to 'recognize' the selected language and forward accordingly.
This should be possible if i used a cookies- or sessions-variable for the language. Unfortunately i don't know how to implement it in a at least half-descent way.

Yes, definately go for session variables. That will solve all of your problems. All of them!

http://www.w3schools.com/PHP/php_sessions.asp

This is how I would go about using session variables for what you are doing:

Where you are checking for $_GET['locale'] (im guessing page controller init function), if it is set then set the session variable:

if (isset($_GET['locale']) 
{
$_SESSION['locale'] = $_GET['locale'];
}

Then, where you are currently using the $_GET['locale'] value, just use the $_SESSION['locale'] instead.

This should mean you only have to put ?locale=xx_XX in where the language is being changed, and no where else, but still all the pages should load in language xx_XX.

Thanks for your reply! Unfortunately i could not get your code working.

Now i added
/* handling of locales */
function getCurrentLanguage() {
$curLang = Session::get('currentLang');
$localeString = "";

if ($curLang == "de") {
$localeString = "de_DE";
return $localeString;
}

elseif ($curLang == "en") {
$localeString = "en_US";
return $localeString;
}
elseif ($curLang == "fr") {
$localeString = "fr_FR";
return $localeString;
}

to the init function of the controller. Is this valid php? Could you give me a hint on how to call a function from within a template?

Yes this is valid code.

To call a function in the template:

$CurrentLanguage

You can test this by putting die('Hello World'); at the start of the function and calling the function from your template.

You really should set $localeString to a default language and always return something (I guess this does depend on how you parse what this function returns).

Your code here relies on you setting the session variable currentLang somewhere else.

Thanks again!
Here is what i did:
In the page class i added a function:

function getCurrentLanguage() {
return Translatable::get_current_locale();
}

In the template i just call the function: <a href="URL/?locale=$getCurrentLanguage">
