[TYPO3-english] Language key in url

[Richard Jäger]

Hey,
right now users can switch language by clicking on german or english on 
the frontpage, it just adds an L=X, like index.php?id=383&L=0

But im using realurl, so its a bit "ugly". If ur surfing the english 
site the url looks like www.xxx.de/en/bookshop.html and in german 
www.xxx.de/de/bookshop.html

So my question is now, is it possible to change the "de" or "en" if 
someone clicks on a language?

Im using a .inc file for that:

<?php
if (!is_object($this)) die ('Error: No parent object present.');

// First, select all pages_language_overlay records on the current page. 
Each represents a possibility for a language.
$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('*', 
'pages_language_overlay', 
'pid='.intval($GLOBALS['TSFE']->id).$GLOBALS['TSFE']->sys_page->enableFields('pages_language_overlay'), 
'sys_language_uid');

$langArr = array();
while($row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($res))       {
         $langArr[$row['sys_language_uid']] = $row['title'];
}

// Little red arrow, which is inserted to the left of the flag-icon if 
the TSFE->sys_language_uid equals the language uid (notice that 
0=english, 1=danish and 2=german is SPECIFIC to this database, because 
these numbers refer to uid's of the table sys_language)
//$pointer = '<img 
src="'.t3lib_extMgm::siteRelPath('cms').'tslib/media/icons_misc/content_client.gif" 
width="7" height="10" alt="" />';
$pointer = '';

// Set each icon. If the language is the current, red arrow is printed 
to the left. If the language is NOT found (represented by a 
pages_language_overlay record on this page), the icon is dimmed.
$flags = array();
$flags[] = ($GLOBALS['TSFE']->sys_language_uid==0?$pointer:'').'<ul 
class="lang_menu"><li><img 
src="fileadmin/templates/images/right_arrow.gif" alt=""/> <a 
href="'.htmlspecialchars('index.php?id='.$GLOBALS['TSFE']->id.'&L=1').'" 
target="_top">English</a></li>';
$flags[] = ($GLOBALS['TSFE']->sys_language_uid==1?$pointer:'').'<li><img 
src="fileadmin/templates/images/right_arrow.gif" alt=""/> <a 
href="'.htmlspecialchars('index.php?id='.$GLOBALS['TSFE']->id.'&L=0').'" 
target="_top">Deutsch</a></li></ul>';

// Make the little menu. Notice, the menu does ONLY transfer the page-id 
and the "L" variable (which is also SPECIFIC for this website because 
"L" has been used in the extension template used to control the language 
setup)
$content = ''.implode('',$flags).'';
?>


Thanks soooo much in advance, i hope u understand my question :)
