如何在cakephp3中使用带有多条记录的valitation和flash消息？

Question

我正在尝试构建一个应用程序来保存cakephp3中的多个记录。

现在，我意识到要创建控制器和视图。 但验证和Flash消息不起作用。 请告诉我如何使用验证消息和闪存消息。

控制器：

public function addition5(){
  $this->ViewBuilder()->layout('auth');
  $articles = TableRegistry::get('articles');
  $entities = $articles->newEntities($this->request->data());
  if($this->request->is('post')){
     $articles->connection()->transactional(function () use ($articles, $entities) {
      foreach ($entities as $entity) {
        $articles->save($entity, ['atomic' => false]);
      }
    });
   //var_dump($entities);
  }
 $this->set(compact('articles'));
 $this->set('_serialize', ['articles']);
}

查看：

echo $this->Form->create($articles,["class" => "article_form"]);
for($i = 0; $i < 5;$i++){
  $j = $i + 1;
  echo '<h2 class="add5">add articles('.$j.'/5)</h2>';
  echo $this->Form->hidden($i.'.user_id',['value' => h($this->request->session()->read('Auth.User.id'))]);
  echo $this->Form->input($i.'.title',['label' => 'title','placeholder' => 'title']);
  echo $this->Form->input($i.'.comment',['label' => 'comment','placeholder' => 'comment']);
}
echo $this->Form->button('submit',["class" => "ok"]);
echo $this->Form->end();
