No, not out of the box. That said, here's a quick and dirty solution that will work with Javascript enabled.

Login as root

Download and install the autotags plugin: http://code.google.com/p/geeklog/downloads/detail?name=autotags_1.1.0_1.8.0.zip

Enable PHP code execution in autotags:
From "Admins only" menu select "Groups"
Find "Autotags Admin" and click "Edit"
Tick the box "autotags.PHP" and click "Save"

Create a new autotag:
From "Admins only" menu select "Autotags"
Click "Create new"
For "Tag" enter "langsel"
Tick the box near "Replace with PHP?"
Click "Save"

Open the file "system/lib-custom.php"
At the bottom of the file (but before the line "?>" ) add the below code and save the file.

PHP Formatted Code
function phpautotags_langsel()
{
global$_USER,$_CONF,$_SCRIPTS;

if($_USER['uid']){
$retval="<a href='".$_CONF['site_url']."/usersettings.php'>Change in profile</a>";
}else{
$_SCRIPTS->setJavascript('

            <script type="text/javascript">

                $(document).ready(function () {

                    $("#langsel").show().change(function () {

                        var selection = $("#langsel option:selected").val();

                        document.cookie = "'.$_CONF['cookie_language'].'=" + escape(selection);

                        location.href = "";

                    });

                });

            </script>

        ');
$language= MBYTE_languageList($_CONF['default_charset']);
$retval='<noscript>This functionality requires JavaScript</noscript>'. LB;
$retval.='<form><div><select id="langsel" style="display: none">'. LB;
foreach($languageas$langFile=>$langName){
$retval.='<option value="'.$langFile.'"';
if($langFile== COM_getLanguage()){
$retval.=' selected="selected"';
}
$retval.='>'.$langName.'</option>'. LB;
}
$retval.='</select></div></form>';
}
return$retval;
}

Create a new block:
From "Admins only" menu select "blocks"
Click on create new
Enter "Language selection" as title and whatever you like for the name
For block content add:

PHP Formatted Code
[langsel:]

Tick the box near "Autotags"
Save and logout

Done. You should now have a language selection block for anonymous users.

Hi,

This is also working as a block without the autotag step. I only changed $_USER['uid'] > 1

PHP Formatted Code
function phpblock_langsel()
{
global$_USER,$_CONF,$_SCRIPTS;

if($_USER['uid']>1){
$retval="<a href='".$_CONF['site_url']."/usersettings.php'>Change in profile</a>";
}else{
$_SCRIPTS->setJavascript('

            <script type="text/javascript">

                $(document).ready(function () {

                    $("#langsel").show().change(function () {

                        var selection = $("#langsel option:selected").val();

                        document.cookie = "'.$_CONF['cookie_language'].'=" + escape(selection);

                        location.href = "";

                    });

                });

            </script>

        ');
$language= MBYTE_languageList($_CONF['default_charset']);
$retval='<noscript>This functionality requires JavaScript</noscript>'. LB;
$retval.='<form><div><select id="langsel" style="display: none">'. LB;
foreach($languageas$langFile=>$langName){
$retval.='<option value="'.$langFile.'"';
if($langFile== COM_getLanguage()){
$retval.=' selected="selected"';
}
$retval.='>'.$langName.'</option>'. LB;
}
$retval.='</select></div></form>';
}
return$retval;
}

Yes it is a really good feature and it could become a default block on new Geeklog install

The solution is in PHP, in fact no one said anything about Java. I mentioned JavaScript, which is a client side scripting language that most modern browsers have built-in, so you don't have to worry about that.

Anyway, read this: http://www.geeklog.net/article.php/20011231130438109
And then use the code from Ben's post.

Ok, so it is an error in my server i think.
i think i know how to create a new php block because i've got a site where it uses more of 100 phpblocks but i'll say you what i did.

1-. Copy and paste the Ben's code in my system/lib-custom.php at the end but before ?>
2-. Create a new block: Title "Language selection" (i think it is no important but i do it), Type phpblock, in options of php block i write "phpblock_langsel" without (). Permisions all checked.
3-. Save

There are some part of code that not work and i don't know why.

1-. I exit of system and visit it like anonymous. (Before i clean cockies in firefox).
2-. Only show the tittle of block (Language selection)

If i delete, in Ben's code, the part

PHP Formatted Code
style="display: none"

, my site show the box with languages. Only two (Spanish and English). That's wright because i only have these languages in my languages directory.

But i switch languages in box and it do nothing.

My site, under construction, www.lawebdelcamping.com
thanks for all.

OK, i can see the problem on your site, you are missing jQuery.

Please put back:

PHP Formatted Code
style="display: none"

And include jQuery:

PHP Formatted Code
function phpblock_langsel()
{
global$_USER,$_CONF,$_SCRIPTS;

if($_USER['uid']>1){
$retval="<a href='".$_CONF['site_url']."/usersettings.php'>Change in profile</a>";
}else{
$_SCRIPTS->setJavascriptLibrary('jquery');// Add this line
$_SCRIPTS->setJavascript('

            <script type="text/javascript">

                $(document).ready(function () {

                    $("#langsel").show().change(function () {

                        var selection = $("#langsel option:selected").val();

                        document.cookie = "'.$_CONF['cookie_language'].'=" + escape(selection);

                        location.href = "";

                    });

                });

            </script>

        ');
// etc...

Try this code below as jQuery library is not set on new install. Do not remove the display: none, It must be working (see demo here).

PHP Formatted Code

function phpblock_langsel()
{
global$_USER,$_CONF,$_SCRIPTS;

$_SCRIPTS->setJavaScriptLibrary('jquery');

if($_USER['uid']>1){
$retval="<a href='".$_CONF['site_url']."/usersettings.php'>Change in profile</a>";
}else{
$_SCRIPTS->setJavascript('

            <script type="text/javascript">

                $(document).ready(function () {

                    $("#langsel").show().change(function () {

                        var selection = $("#langsel option:selected").val();

                        document.cookie = "'.$_CONF['cookie_language'].'=" + escape(selection);

                        location.href = "";

                    });

                });

            </script>

        ');
$language= MBYTE_languageList($_CONF['default_charset']);
$retval='<noscript>This functionality requires JavaScript</noscript>'. LB;
$retval.='<form><div><select id="langsel" style="display: none">'. LB;
foreach($languageas$langFile=>$langName){
$retval.='<option value="'.$langFile.'"';
if($langFile== COM_getLanguage()){
$retval.=' selected="selected"';
}
$retval.='>'.$langName.'</option>'. LB;
}
$retval.='</select></div></form>';
}
return$retval;
}

I've created an improved solution for this issue.
The new solution also works without JavaScript and for logged-in users.
