simple Solution: use a non-image-extension in the function-call like
<?php if(function_exists('language_menu')) { language_menu('txt'); } ?>
it replace only the file extension from the menu code and show's the ALT-Text from the image (not W3C-valide!!)
better solution: replace the function
set_language_icon() with the same name in
modules / mod_multilingual / lang.functions.php<?php //for colored code only, dont copy this line
function set_language_icon ($pageId = 0, $ext='gif' )
{
if (!preg_match("/jpg|png|gif|svg|txt|TXT/", $ext)) $ext='gif';
$return_value = array();
$mod_path = dirname(__FILE__);
$mod_rel = str_replace($_SERVER['DOCUMENT_ROOT'],'',str_replace('\\', '/', $mod_path ));
$mod_name = basename($mod_path);
$array = get_page_languages();
$array2= get_pageCode_values( $pageId );
$langPageArray = array_merge($array , $array2);
foreach( $langPageArray as $key=>$value )
{
$langKey = $key;
if($array[$langKey]['visibility'] == 'hidden') {continue;}
$page_title = get_languages($langKey);
$langUrl = get_page_url( $value);
$class = strtoupper($langKey) == LANGUAGE ? 'class="current"' : ' class="default"';
$return_value [ $langKey ] = "\t\t".'<a '.$class.' href ="'. $langUrl .'" title="'.$page_title.'" >'.PHP_EOL;
$return_value [ $langKey ] .= "\t\t\t".'<span>';
if ($ext=='TXT'){
$return_value [ $langKey ] .= " $page_title " ;
} else if ($ext=='txt'){
$return_value [ $langKey ] .=" $langKey " ;
} else {
$return_value [ $langKey ] .= PHP_EOL."\t\t\t\t".'<img src="'.WB_URL.'/modules/'.$mod_name.'/flags/'.strtolower( $langKey ).'.'.$ext.'" alt="'.$page_title.'" title="'.$page_title.'" />'.PHP_EOL."\t\t\t";
}
$return_value [ $langKey ] .= '</span>'.PHP_EOL."\t\t".'</a>'.PHP_EOL;
}
return $return_value;
}
}
now you have different way's to call the language menu
1. Extension ==
txt - Result is the language Key like
DE EN as your menu
<?php if(function_exists('language_menu')) { language_menu('txt'); } ?>
2. Extension ==
TXT - Result is the page titel of the first page in every avaiable language like
Deutsch English as your menu
<?php if(function_exists('language_menu')) { language_menu('TXT'); } ?>
3. Extension ==
gif - Result are the flags of the first page in every avaiable language like

as your menu with gif-files
<?php if(function_exists('language_menu')) { language_menu('gif'); } ?>
3. Extension ==
png - Result are flags of the first page in every avaiable language like

as your menu, but with png-files
<?php if(function_exists('language_menu')) { language_menu('png'); } ?>
the function
set_language_icon() allowed also jpg-files and svg-files. but for this file extension, you have to add a flag-set into folder
modules / mod_multilingual / flagsP.S. Code is part of the next module version
