如何解决CakePhp-如何从购物车列表中删除购物车行

我的购物车列表显示以下列列表。

产品价格数量总计

产品1 200 5 1000

Product2 300 3 900

我的Carts控制器中具有Index.php的此Cart列表。如何从列表中删除添加的项目？

下面的index.php代码实际上显示了添加的项目列表。

<?php
        $total=0;
    ?>
    <!-- slider Area Start-->
    <div class="slider-area ">
        <!-- Mobile Menu -->
        <div class="single-slider slider-height2 d-flex align-items-center" data-background=<?= @$this->Url->build('/img/hero/category.jpg')?>>

在我的Cart控制器中删除函数，如下所示：

 public function delete($id = null)
    {
        $this->request->allowMethod(['post','delete']);
        $cart = $this->Carts->get($id);
        if ($this->Carts->delete($cart)) {
            $this->Flash->success(__('The cart has been deleted.'));
        } else {
            $this->Flash->error(__('The cart could not be deleted. Please,try again.'));
        }

        return $this->redirect(['action' => 'index']);
    }
