[TYPO3] set language variable from TS

[Sebastian Fuchs]

Hi,
just wanted to post my solution to my problem. probably it helps 
somebody....

for the country selection i use now a menu generated by a userfunction.

This userfunction takes 3 TS varaibles defining
a. the Page UIDs of the menu items to show
b. the sys_language uids to link to
c. the sys_language uids to display the link in

with this function i am sure that the different country trees are 
entered in a defined language.

it is called by this TS-snip:

temp.menu_international = COA
temp.menu_international {
20 < temp.menu_mask
20.special = userfunction
20.special.userFunc = user_menuFunc->makeInternationalMenu
20.special.userFunc.value = 3,270,540
20.special.userFunc.lang = 1,2,5
20.special.userFunc.displaylang = -1

}

the file has to be included and now the class-code:




require_once(PATH_tslib."class.tslib_pibase.php");

class user_menuFunc extends tslib_pibase {

	var $prefixId = "user_menuFunc";		// Same as class name
	var $scriptRelPath = "scripts/class.user_menuFunc.php";	// Path to this 
script relative to the extension dir.

   /** Build the international menu
   *  conf parameters are:
   *  userFunc.value = comma-sep-list of page uids in the menu (e.g. 3,244)
   *  userFunc.lang = comma-sep-list of language_uids to link to or 
single negative value for all entries to link to (e.g 0,3,5 or -5)
   *  userFunc.displaylang = comma-sep-list of language_uids to display 
the link in or single negative value for all entries display in (e.g 
0,0,1,3,5 or -5)
   * @param	string Content-String
   * @param	array TS-Configuration Array
   * @return	array of menu entries
   * @access public
   */
   function makeInternationalMenu($content,$conf){
	//debug($conf);
	if ( isset($conf['userFunc.']) && isset($conf['userFunc.']['value']) ) {
		$pid_arr = t3lib_div::intExplode(',',$conf['userFunc.']['value']);
		$lang_arr = t3lib_div::intExplode(',',$conf['userFunc.']['lang']);
		$displaylang_arr = 
t3lib_div::intExplode(',',$conf['userFunc.']['displaylang']);

		$ret_arr = array();
		for($i=0;$i<count($pid_arr);$i++){
			if( $lang_arr[0] < 0 || !isset($lang_arr[$i])){
				$lang_id = abs($lang_arr[0]);
			} else {
				$lang_id = $lang_arr[$i];
			}
			if( $displaylang_arr[0] < 0 || !isset($displaylang_arr[$i])){
				$displaylang_id = abs($displaylang_arr[0]);
			} else {
				$displaylang_id = $displaylang_arr[$i];
			}

			$uid = $pid_arr[$i];
			if($displaylang_id>0) {
				$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('*', 
'pages_language_overlay', 'pid='.$uid.' AND 
sys_language_uid='.$displaylang_id , 'uid,title');
				$row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($res);
			} else {
				$row = $this->pi_getRecord('pages',$uid,1);
			}
			if ( is_array($row) ) {
				$titel = $row['title'];
			} else {
				continue;
			}

			if( $lang_id>0 ){
				$param=array('L'=>$lang_id);
			} else {
				$param=array('L'=>0);
			}
			$ret_arr[$i] = array(
								'title' => $titel,
								'_OVERRIDE_HREF' => $this->pi_getPageLink($uid,'',$param),
							);
		}
		return $ret_arr;
	} else {
		return array();
	}
   }  //  makeInternationalMenu

}
