Question

我想在不同表中的$ model-> product中添加proid，我想获取添加到购物车中的产品id并将它们存储在以逗号分隔的DB（phpmyadmin）中

controller.php（我从那里获取会话）

class CartController extends \yii\web\Controller
{
    public $totalItems=0;
    public $totalPrice=0.00;
    //public $netPrice = 0;

    public function actionAdd($id = null)
    {
        if(!intval($id) || empty($id)){
           Yii::$app->session->setFlash('error','cannot find this product');
            return $this->redirect('/front');

        }

        if(!isset(Yii::$app->session['cart'])){
            Yii::$app->session['cart'] = [];
            Yii::$app->session['total_items'] = 0;
            Yii::$app->session['total_price'] = 0.00;

        }
           $this->addtocart($id);

           $this->setTotal();
           //$model = new Orders();
           //$model->ordername = ;
              // $model->ordertotal = $netPrice ;
            return $this->redirect('index');


    }
    public function addtocart($id){
        if(isset(Yii::$app->session['cart'][$id])){
            $session = Yii::$app->session['cart'];
            $session[$id]= $session[$id] +=1;
            Yii::$app->session['cart']= $session;
        }
        else{
            $session = Yii::$app->session['cart'];
            $session[$id] = 1;
            Yii::$app->session['cart'] = $session;
        }
    }
    public function setTotal(){
        Yii::$app->session['total_items']=$this->totalItems(Yii::$app->session['cart']);
        Yii::$app->session['total_price']=$this->totalPrice(Yii::$app->session['cart']);

        $this->totalItems = Yii::$app->session['total_items'];
        $this->totalPrice = Yii::$app->session['total_price'];





    }
    public function totalItems($cart){
        $totalItems = 0;
        if(is_array($cart)){
            foreach ($cart as $id=>$qty){
                $totalItems += $qty;
            }

            return $totalItems;
        }
        //return $totalItems;
    }
    public function totalPrice($cart){
        $netPrice = 0.00;
        if(is_array($cart)){
            foreach ($cart as $id=>$qty){
                $item = $this->findProduct($id);
                $netPrice += $item->price * $qty;
            }
            //return $netPrice;
        }
        return $netPrice;
    }


    public function findProduct($id){
        return Products::findOne($id);
    }
    public function updateCart(){
        foreach(Yii::$app->session['cart'] as $id=>$qty){
            if(isset($_POST[$id])){
                if($_POST == 0){
                    $session = Yii::$app->session['cart'];
                    unset($session[$id]);
                    Yii::$app->session['cart'] = $session;
                }
                else{
                    $cart = Yii::$app->session['cart'];
                    $cart[$id] = $_POST[$id];
                    Yii::$app->session['cart'] = $cart;
                }
            }
        }
    }


    public function actionIndex()
    {
        if(!isset(Yii::$app->session['cart']) || empty(Yii::$app->session['cart'])){
            Yii::$app->session->setFlash('error','cart is empty');

        }
// i made a table named order with colums ordertotal and products where ordertotal should store the total value and products should store the product id which are added to cart got the order total but didn't get products
            $model = new Orders();
            $model->ordertotal = $this->totalPrice(Yii::$app->session['cart']); //got the order total from this 
           //$model->product=add the product id( <?= Html::a('AddToCart',['/cart/add','id'=> $p->proid], ['class' => 'btn btn-success']) ?> //this is my product page where i 'add to cart' from) seperated by comma

        if($model->save()){
            print_r('ok');

        }
        else{
           echo $model->getErrors();

        }



        return $this->render('index',[
            'totalItems' => $this->totalItems(Yii::$app->session['cart']),
            'totalPrice' => $this->totalPrice(Yii::$app->session['cart']),
        ]);
    }

}

我从t = PLX5MZfWdby5QFDLU-Ov7Ixv6AilU-mgcQ获得了上面的代码”

实现新模型并将其添加到db是我的实现

product.php

<?php foreach ($product as $p) { ?>
                <div class="col-md-4">

                    <h2><?php echo $p->name?></h2>
                    <?php echo "<br/>"?>
                    <?php echo "Name: ".$p->name?>
                    <?php echo "<br/>"?>


                     <?php echo "price: ".$p->price?>
                    <?php echo "<br/>"?>
                    <?= Html::a('AddToCart',['/cart/add','id'=> $p->proid], ['class' => 'btn btn-success']) ?>



                </div>
            <?php } ?>

您必须更改服务器功能，首先需要更改addtocart功能。

添加Yii::$app->session['cart']['id'][] = $id;

Yii2商店产品ID（以逗号分隔）
