Filter language in query_posts?

Hello, the solution looks easy… but doesn’t works for me.

I would like to display only post of the selected language.

The whole page is correctly translated but it always display post of any language.

here is the simplified code of my page :

<?php get_header(); ?>

<div class="SC">

<div class="co3">

<div class="actu-droite">

<h3><?php _e('ACTU','DBG');?></h3>

<?php

$args = array('lang' => 'en_us' );

$myposts = get_posts( $args );

foreach($myposts as $post) : setup_postdata($post);

?>

<div class="actu">

<div class="p-head">

<h3><a href="<?php the_permalink(); ?>"><?php the_title()?></a></h3>

</div>

<div class="p-con">

<p class="p-date-cat"><?php the_time('j-m-y') ?> | <?php _e('In:','DBG');?> <?php the_category(', ') ?></p>

<p><?php echo truncate($post->post_content,256); ?></p>

</div>

<ul class="p-det">

<li class="p-det-com"><?php comments_popup_link(__('No Comments','DBG'), __('(1) Comment','DBG'), __('(%) Comments','DBG')); ?></li>

<li class="p-det-more"><a href="<?php the_permalink()?>"><?php _e('More...','DBG');?></a></li>

</ul>

<?php endforeach; ?>

</div>

</div>

</div>

<?php get_footer(); ?>

Every text displayed with _e is translated in the correct language.

I tried this but had not luck, any ideas on fixing it. Using the latest WP3.4.1 and latest XILI-Language:

<?php

$args = array(

‘cat’ => 12,

‘numberposts’ => 20,

‘orderby’ => ‘date’,

‘order’ => ‘DESC’,

‘post_type’ => ‘post’,

‘post_status’ => ‘publish’,

‘lang’ => the_curlang()

);

$postslist = get_posts( $args );

foreach($postslist as $post):

setup_postdata($post);?>

<?php the_field(‘story’); ?>

<hr>

<?php endforeach;?>

I created multi site in wordpress using xili language plugin. Site has blog too. Site main language is Italian, when I click on Blog menu it landed to Spanish site. Please check following url

I check current language by following function, it shows es_es

the_curlang()

I want If I click Blog menu on Italian site then Blog menu must be Italian, If I am on English site and click on Blog menu then menu must be English same as Spanish site.

Hope you understand. I need its solution urgently. Please reply me soon
