Thanks for the link... the code works for adding comments to other languages.

I still have one problem however...

comments are duplicated to reviews areas on other pages where they do not belong. How can i keep comments linked to posts where they were created?

please see post_pg.png as attached previously

- If you disable WPML comment merging plugin, does the comments remains duplicate?
- If you disable WPML multilingual plugin, does the comments remains duplicate?

I'll wait for your findings.

hi there

my apologies for the late reply...

if i disable WPML comment merging then problem of comments showing on reviews section is solved.

if i disable WPML multilingual plugin then my reviews section disappears as well as other features such as image gallery etc.

i have decided to remove the reviews area on the affected pages to avoid this problem. I need the duplication of post comments to translated pages, but cannot afford to have these comments displaying on review areas. This is a solid but temporary solution to the problem. I hope that the folks from WPML Comment merging will once again update their plugin to avoid this feature.

🙂 thanks for the assistance

Here's a possible solution. It's not tested because I took the snippet out of our codebase.


global $sitepress;
remove_filter('comments_clauses', array( $sitepress, 'comments_clauses' ), 10);
add_filter('pre_get_comments', 'my_pre_get_comments', 100, 1);

function my_pre_get_comments(\WP_Comment_Query &$wp_comment_query)
    if (($postId = $wp_comment_query->query_vars['post_id'])) {
        $postIds = [$postId];

        // get all languages
        $languages = apply_filters('wpml_active_languages', null, 'skip_missing=1');
        $type = get_post_type($postId);
        foreach($languages as $l) {
            if(!$l['active']) {
                $otherId = apply_filters('wpml_object_id', $postId, $type, false, $l['language_code']);
                if ($otherId) {
                    $postIds[] = $otherID;

        // don't query for a specific post, instead query all language posts
        $wp_comment_query->query_vars['post_id'] = '';
        $wp_comment_query->query_vars['post_ID'] = '';
        $wp_comment_query->query_vars['post__in'] = $postIds;
