[Plugin : Polylang] – How to get the latest comments for the current language ?

Hi, I find a solution which works using the fine polylang API :

//Original : does not manage language. display all comments. doesn't care about the comment language
		//$comments = get_comments( array( 'number' => $number, 'status' => 'approve' ) );
		/************************************************************/

		$current_lng= pll_current_language(); //retrieve current language
		$lng_objects = get_posts(array(
		'post_type' => 'post',
		'lang' => $current_lng, // use language slug in the query
		'showposts' => 150 //remove if problem. here for perf. this prevents loading all posts.
));
$lng_ids=array() ;
foreach ($lng_objects as $objects)
	array_push($lng_ids, $objects->ID) ;
$string_lng_ids=implode(",", $lng_ids); //build ID string for sql query

global $wpdb;
$query_lng_comments="
select wp3_comments.*
from wp3_comments
inner join wp3_posts on wp3_posts.ID=wp3_comments.comment_post_ID
where comment_approved=1
and wp3_posts.ID in ($string_lng_ids)
order by comment_date desc
limit 0,$number
";
$comments=$wpdb->get_results($query_lng_comments);
/*********************************************************/

Hope this could help.

Don’t know why either. Thanks for your answer.
