Question

我从cakephp2切换到cakephp3。在这里我无法理解，如何存储相关数据。我有一个名为Orders的表和一个名为Ordersarticles的表。有一个视图，其中订购了订单信息和多个orderarticle。现在我想将数据存储在控制器中。

我有以下代码

  public function add(){

   $order = $this->Orders->newEntity();

   if ($this->request->is('post')) {

      $order = $this->Orders->patchEntity($order, $this->request->getData());

      $i = 0; //Index for each Field
      foreach($order->Orderarticles['article_id'] as $oaarticleid){
        $orderarticles = [
            'article_id' => $oaarticleid,
            'amount' => $order->Orderarticles['amount'][$i]
        ];
        $i++;
      }

      $order['Orderarticles'] = $orderarticles;

      //Store Order
      if ($result = $this->Orders->save($order)) {

        //Store orderArticles
        $this->Flash->success(__('The order has been saved.'));

        //return $this->redirect(['action' => 'index']);
      }
      $this->Flash->error(__('The order could not be saved. Please, try again.'));
  }

循环中的orderArticles准备正确的格式。但是，当我想存储信息时，只存储订单，而不是存储订单。我完全不知道如何存储其他信息...

我还尝试先存储订单，获取插入的ID，然后存储orderarticles。但我完全失败了。我觉得在Cakephp中有新的东西。你能救我吗？

我猜你在保存订单后不想这样做。

   if ($result = $this->Orders->save($order)) {
        $articles = $this->request->getData("articles");

        $i = 0;
        foreach ($articles as $article) {
            $data = [
                'article_id' => $result->id,
                'amount' => $i++
            ];
            $article = $this->Orderarticles->newEntity();
            $article = $this->Orderarticles->patchEntity($article, $data);
            $this->Orderarticles->save($article);
        }
    }
