Question

我使用交易评论，因此每条评论都会收到多个回复。我需要得到每个评论的回复计数。我不需要所有评论的总回复数。

我尝试使用此代码：

viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @Override
            public void onPageSelected(int position) {
                if(adapter != null){
                    adapter.getItem(position).onResume();
                }
                Toast.makeText(getApplicationContext(), "Page Selected", Toast.LENGTH_LONG).show();
            }

            @Override
            public void onPageScrollStateChanged(int state) {

            }
        });

另一种方式显示总回复而不是我正在寻找的内容..此代码显示所有评论的所有回复。

functions.php中的代码

$comment_id = get_comment_ID();

$childrenCount = get_comment_meta( $comment_id, "childrenCount" );

$childrenCountNumber = count($childrenCount);

echo $childrenCountNumber

然后在模板页面中回显：

function replies_counter($id){
global $wpdb;
$query = "SELECT COUNT(comment_post_id) AS count FROM $wpdb->comments 
WHERE `comment_approved` = 1 AND `comment_post_ID` = $id AND 
`comment_parent` = 0";
$parents = $wpdb->get_row($query);
return $parents->count;
}

这一个是关于获得所有评论的总回复数。但我需要单独回复每条评论的数量。

如果有人帮助我会很好。

Answer 1

我总是喜欢使用WordPress核心功能，如果有一个可以做我想要的。

您可以使用get_comments轻松实现这一目标。将count arg设置为true。这样它只会检索注释计数。

$args = array(
    'post_id' => $post->ID, //main post id
    'parent' => get_comment_ID(), //the comment id
    'count' => true, //just count
);
$comments = get_comments($args); //number of comments;

Answer 2

为什么不编写这样的自定义函数来按ID获取每个评论的子评论？

function subreplies_counter($id){
  global $wpdb;
  $query = "SELECT COUNT(comment_ID) AS count FROM $wpdb->comments 
  WHERE `comment_approved` = 1 AND `comment_parent` = $id";
  $data = $wpdb->get_row($query);
  return $data->count;
}

这是comment.php中的代码

<?php
/**
 * The template for displaying comments.
 *
 * This is the template that displays the area of the page that contains both the current comments
 * and the comment form.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package Astra
 * @since 1.0.0
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly.
}

/*
 * If the current post is protected by a password and
 * the visitor has not yet entered the password we will
 * return early without loading the comments.
 */
if ( post_password_required() ) {
    return;
}
?>

<div id="comments" class="comments-area">
