注释/回复ID是表单实际发送的值。您可以通过$_GET:

// Default is "no reply" eq. 0
$id = 0;
// Handle replies
if ( isset( $_GET[\'replytocom\'] ) )
{
    $id = filter_var(
        $_GET[\'replytocom\'],
        FILTER_VALIDATE_INT,
        # or:
        # FILTER_SANITIZE_NUMBER_INT
        array(
            \'options\' => array(
                \'min_range\' => 1,
            ),
            # @link http://www.php.net/manual/en/filter.filters.flags.php
            # \'flags\'   => \'\',
        )
    );
    if ( FALSE === $id )
        break;

    $id = absint( $_GET[\'replytocom\'] )
}

好吧，我的错！

我查过了什么get_comments(); 返回，我发现comment_parent 包含初始注释ID的字段。因此，为了添加您想要回复的评论引用，您需要执行以下操作：

<?php
    $pid = get_the_id();            
    $comments = get_comments(\'post_id=\'.$pid);

    foreach ( $comments as $comment ) {         
        $cpid = $comment->comment_parent; // Getting the ID of the parent comment
        $comment_parent = get_comment( $cpid );

        // Do comment rendering here
        ...
    }
?>
