将以下函数放入主题函数中。php，然后将<?php echo tnc_reactions_count($post->ID); ?> 在你的单曲里。php输出数字。让我知道它是否工作，因为我还没有完全测试它。

function tnc_reactions_count($post_id){
    global $wpdb;
    $comments_table = $wpdb->prefix.\'comments\';
    $commentsmeta_table = $wpdb->prefix.\'commentmeta\';
    $get_post_comments = $wpdb->get_results( "SELECT * FROM $comments_table WHERE comment_post_ID=\'$post_id\'", OBJECT );
    $funny_total = 0;
    $sad_total = 0;
    $hate_total = 0;
    $good_total = 0;

    foreach ($get_post_comments as $key => $value) {
        $comment_id = $value->comment_ID;
        $query_reaction = $wpdb->get_results( "SELECT * FROM $commentsmeta_table WHERE `comment_id`=\'$comment_id\' AND `meta_key`=\'comments_reactions\'", OBJECT );

        foreach ($query_reaction as $key => $value) {

            $get_reaction = $value->meta_value;

            switch ($get_reaction) {
                case \'funny\':
                    $funny_total += 1;
                    break;

                case \'sad\':
                    $sad_total += 1;
                    break;

                case \'hate\':
                    $hate_total += 1;
                    break;

                case \'good\':
                    $good_total += 1;
                    break;
            }
        }
    }
    $output = \'<h3>Reactions</h3>\';
    $output .= \'Funny: \'.$funny_total;
    $output .= \'Sad: \'.$sad_total;
    $output .= \'Hate: \'.$hate_total;
    $output .= \'Good: \'.$good_total;

    return $output;
}
