How to display comments in reverse order with pagination?

  • Resolved Andry

    There is a need to implement a toggle button, that when it is pressed, the comments that were shown to the post, with pagination (from old to new) after its pressing were displayed from new to old (with the same pagination). In the documentation of wp_list_comments() there is a description of the ‘reverse_top_level’ parameter which is responsible for that. But in my case something goes wrong. Here is my code

    <?php if (post_password_required()) {
    return;
}
$post_id = get_the_ID();
$per_page = 4;
$comments_count = get_comments_number($post_id);


if (isset($_GET['cpage']) && is_numeric($_GET['cpage'])) {
    $page = (int)$_GET['cpage'];
}
$page = max(1, $page);

if ($GET_value_filter == 'newest') { /// In this parameter, I take away from the GET parameter of the page that this is sorting from new comments to old comments.
           
            function custom_default_comments_page2($value)
            {
                return 'newest';
            }

            add_filter('pre_option_default_comments_page', 'custom_default_comments_page2');

            $arg = array(
                'type' => 'comment',
                'reverse_top_level' => 1,
                'callback' => 'reviews_theme_comment',
                'per_page' => $per_page,
                'number' => $per_page,
                'cpage' => $page,
            );
            

            wp_list_comments($arg);
   
        }

    This is where 2 errors occur.

    1. I expect the first page of comments to show me 4 comments (‘per_page’ => 4), but for some reason it shows me only 2 *It should be clarified that when displaying comments from old->new it is indeed the last page with 2 comments. But here the first page should have 4 comments.
    2. The last page of pagination contains the same set of comments as the first one, no matter how many comments are displayed per page….

    I need to get comments for a custom post type, and these paginated comments should not conflict with the theme that users leave for posts. So I shouldn’t care what the site administrator sets in this set.

    Can anyone have something useful to say about this problem?

    @sajjadakbari Thanks for the explanation, but the solution you suggested doesn’t work.

    @sajjadakbari Unfortunately, your advice did not solve the problem. Can you show with a real example?

    https://alteredspoon.s3-tastewp.com/wp-admin/

    [redacted]

    I created test post with comments

    https://alteredspoon.s3-tastewp.com/test/ and when I push link https://alteredspoon.s3-tastewp.com/test/?filter=newestI need order this comments in correct pagination but it doesn’t work

    elseif ($GET_value_filter == 'newest') {

            echo '<h1>We need to show newest order comments</h1>';


            $comment_count = wp_count_comments($post_id);
            $comments_count = $comment_count->approved;

            $offset = ($page - 1) * $per_page;


            $args = array(
                'type' => 'comment',
                'status' => 'approve',
                'post_id' => $post_id,
                'order' => 'DESC',
                'offset' => $offset,
                'number' => $per_page,
            );

            $comments = get_comments($args);

            wp_list_comments(array(
                'type' => 'comment',
                'callback' => 'reviews_theme_comment',
                'comments' => $comments,
                'total' => $comments_count,
                'per_page' => $per_page,
                'reverse_top_level' => true,
            ));
    }

    You can correct this code on \wp-content\themes\twentytwenty\template-parts\custom-comments-template.php

    @sterndata Can you propose other way to show sandbox for WordPress ?

    here’s one: https://wpsandbox.net/

    BUT do not post IDs and passwords here, for a sandbox, test site, staging site, or real site. It sets a bad example and not everyone is careful.

    @sajjadakbari Unfortunately, the solution you suggested doesn’t work. Here is the full code of the page with comments.
