我只为我的wordpress网站选择了两个级别的评论。如何显示第一级的注释数？（深度-1）
GET_COMMENTS_NUMBER of Depth-1(级别1)(1帖子)

在wp\\U注释表中，如果comment_parent 等于0，这是一级注释。
function get_num_toplevel_comments() {
global $wpdb;
return $wpdb->get_var("
SELECT COUNT(*)
FROM $wpdb->comments
WHERE comment_parent = 0
");
}

基于akTed\'s答案：
function get_top_level_comments_number( $post_id = 0, $onlyapproved = true ) {
global $wpdb, $post;
$post_id = $post_id ? $post_id : $post->ID;
$sql = "SELECT COUNT(*) FROM $wpdb->comments WHERE comment_parent = 0 AND comment_post_ID = $post_id";
if( $onlyapproved ) $sql .= " AND comment_approved=\'1\'";
return (int) $wpdb->get_var( $sql );
}

使用中的代码this answer 只删除一个!:
add_filter( \'comments_clauses\', \'wpse_78628_top_comments_only\' );
$comments = get_comments();
remove_filter( \'comments_clauses\', \'wpse_78628_top_comments_only\' );
function wpse_78628_top_comments_only( $clauses )
{
$clauses[\'where\'] .= \' AND comment_parent = 0\';
return $clauses;
}

下面是一些完整的工作代码，基于前面的答案。
<?php
add_filter( \'comments_clauses\', \'wpse_78490_child_comments_only\' );
function wpse_78490_child_comments_only( $clauses )
{
$clauses[\'where\'] .= \' AND comment_parent != 0\';
return $clauses;
}
$count = get_comments( array(\'post_id\' => $post->ID, \'count\' => true) ); echo $count; ?>
结束
