Cakephp-单击“添加到购物车”按钮后，不会重定向到购物车项目页面“购物车/索引”

如何解决Cakephp-单击“添加到购物车”按钮后，不会重定向到购物车项目页面“购物车/索引”

您可以在视图中看到添加单个产品的代码。

当我按下添加到购物车按钮时，如下所示。

 <?= $this->Form->submit('add to cart',['class'=>'btn_3']); ?>

它实际上将数据保存在phpmyadmin的carts表中，但没有重定向到我必须结帐的cart物品页面。

<div class="single_product_text text-center">
            <h3><?= h($product->name) ?></h3>
            <p><?= h($product->description) ?></p>

            <?= $this->Form->create(null,['id'=>'cartForm','url'=>['controller' => 'Products','action' => 'addItem',$product->id]]); ?>
              <div class="card_area">
                  <div class="product_count_area">
                      <p>Quantity</p> 
                      <div class="product_count d-inline-block">
                        
                          <span class="product_count_item inumber-decrement"> <i class="ti-minus"></i></span>
                          <?= $this->Form->hidden('user_id',['value'=>$this->request->getSession()->read('Auth.User.id')]); ?>
                          <?= $this->Form->hidden('product_id',['value'=>$product->id]); ?>
                          <?= $this->Form->hidden('price',['value'=>$product->sell_price]); ?>
                          <?= $this->Form->input('quantity',['class'=>'product_count_item input-number','value'=>1,'min'=>0,'max'=>6,'label' => false,]); ?>
                          <span class="product_count_item number-increment"> <i class="ti-plus"></i></span>
                        
                        
                      </div>
                      <p>$<?= h($product->sell_price) ?></p>
                  </div>
                <div class="add_to_cart">
                    <?= $this->Form->submit('add to cart',['class'=>'btn_3']); ?>
                </div>
              </div>
            <?= $this->Form->end(); ?>
          </div>
        </div>

您可以在Products控制器中看到additem函数，在该控制器中我试图将其重定向到Carts Index页面。目前它只是重定向到同一页面。 @GregSchmidt，但它将数据保存在数据库表购物车中。

public function addItem($id = null)
    {
        $cartModel = $this->loadModel('Carts');

        $cart = $cartModel->find()
        ->where(['Carts.product_id' => $id,'Carts.user_id' => $this->request->getData('user_id')])
        ->contain(['Products']);

        if($cart->isEmpty())
        {
            $cart = $cartModel->newEmptyEntity();
            if ($this->request->is('post')) 
            {
                $cart = $cartModel->patchEntity($cart,$this->request->getData());
                if ($cartModel->save($cart)) 
                {
                    return $this->redirect(['controller'=>'Products','action' => 'view',$id]);
                }
                $this->Flash->error(__('The cart could not be saved. Please,try again.'));
            }//end of post if
        }//end of isEmpty if
        else
        {
            if ($this->request->is(['patch','post','put'])) 
            { 
                foreach($cart as $cart1)
                {
                    $cart1->quantity += $this->request->getData('quantity');
                    if ($cartModel->save($cart1)) 
                    {
                 //       $this->Flash->set(__('The cart has been saved.'),['element'=>'success']);
                        return $this->redirect(['controller'=>'Carts','action' => 'index']);
                    }
                    $this->Flash->set(__('The cart could not be saved. Please,try again.'),['element'=>'error']);
                }//end of foreach
            }//end of if
        }//end of else
