Php mvc体系结构中的嵌套注释

我正在创建一个没有框架的MVC架构的网站。在博客中也有类似的评论。我希望能够回答一个评论。但是回答功能不起作用（当我想回答一条评论时，它与第一条评论相同），我很难找到原因？你能帮我吗？以下是网站地址：cedricjager.com/stream

下面是connection.php：

class Connection {

// Connection
private function getBdd() {
try {
  $bdd = ConfigDB::database();
  $pdo = new PDO("mysql:host={$bdd['host']}; dbname={$bdd['db_name']}", "{$bdd['username']}", "{$bdd['password']}");
  $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
  print "Error!: " . $e->getMessage() . "<br/>";
  die();
}
return $pdo;
}

// Query
public function query($sql, $params = array(), $fetch = null) {
try {
  $req = self::getBdd()->prepare($sql);
  $req->execute($params);

  if ($fetch == 'one') {
    return $req->fetch();
  } else if ($fetch == 'all') {
    return $req->fetchAll();
  } else {
    return $req;
  }

 } catch (PDOException $e) {
  print "Error!: " . $e->getMessage() . "<br/>";
  die();
 }
 }

<div id="comment-<?= $critic['id'] ?>">

<span class="text-muted">le <?= $critic['date'] ?></span>
</p>
<div class="blockquote">

    <input type="hidden" name="valeur" value="<?= $critic['id_movie'] ?>">
    <input type="hidden" name="idval" value="<?= $critic['id'] ?>">
    <?php if($critic['depth'] <= 1): ?>
      <button  type="button" class="reply btn btn-default" data-id="<?= $critic['id'] ?>"><i class="fas fa-comments"></i></button>
    <?php endif; ?>
    <button type="submit" name="signal" class="btn btn-default"><i class="fas fa-bolt"></i></span></button>
  </p>
  </form>

  </div>

 <div id="answer">
<?php if(isset($critic['children'])): ?>
    <?php foreach($critic['children'] as $critic): ?>
        <?php require('comments.php'); ?>

<?php endif; ?>

首先，我相信您从未设置“comment.php”视图中提到的
子索引：

<?php if(isset($critic['children'])): ?>
    <?php foreach($critic['children'] as $critic): ?>
        <?php require('comments.php'); ?>
    <?php endforeach; ?>
<?php endif; ?>

现在评论家应该有一个“儿童”索引，其中列出了所有儿童。它允许您无限制地构建注释树。
您需要记住的是，在发布新评论时正确设置父id

如果它解决了你的问题，请告诉我

      <div class="sectioncomments" id="comments">
    <?php foreach($critics as $critic): ?>
        <?php require('comments.php'); ?>
    <?php endforeach; ?>
  </div>
  <hr>
