Yii2和COOKIES不在拳头加载页面上显示

Question

我使用Yii2框架。我将cookie用于购物车，当有人打开网站并在购物车中添加产品时，我使用cookie中的uniqueID将其添加到表中。问题是，当我第一次在浏览器中打开网站时，$ _ COOKIE不会在功能中显示，但是会生成它。当我刷新页面时，一切正常... 我在这里生成Cookie

if(isset($_COOKIE['uniqueID'])){
    $curr_user = $_COOKIE['uniqueID'];
  }else{
    $expire = time() + 3600;// valid one year
    setcookie('uniqueID', uniqid(), $expire);
    $curr_user = $_COOKIE['uniqueID'];
  }

在这里我将产品添加到购物车：

 <button class="addToCart" type="button" data-toggle="tooltip" title="<?=Yii::$app->OutData->getLabel(56)?>" onclick="buyProductWithQty(<?=$promoProduct->id?>,1,'<?php echo $curr_user?>')"><i class="fa fa-shopping-cart"></i> <span class=""><?=Yii::$app->OutData->getLabel(55)?></span></button>

这是一个功能：

function buyProductWithQty(product_id, quantity, user) {
$.ajax({
    url: '/admin/site/buyproductwithqty',
    method: "POST",
    data: {
        product_id: product_id,
        qty: quantity,
        user:user
    },
    success: function (data) {
        var data = JSON.parse(data);
        if (data['reload'] == 1) {
            addProductNotice2(data['msg'], 'success');

            setTimeout(function(){ location.reload(); }, 2000);
        } else {
            //alert(data['msg']);
            addProductNotice2(data['msg'], 'danger');
            //$.notify(data['msg'], {globalPosition: 'bottom center'});
        }
    }
});

}

这是控制器中的功能：

public function actionBuyproductwithqty() {
    if (isset($_POST['product_id']) and ! empty($_POST['product_id']) and isset($_POST['qty']) and ! empty($_POST['qty'])) {
        $product_id = (int) $_POST['product_id'];
        $quantity = (int) $_POST['qty'];
        $flag = 0;
        $productKey = 0;
        $result['reload'] = 1;
        $result['msg'] = 'Успешно добавен продукт в количката!';
        $product = Product::findOne($product_id);
        if ($product) {
            $productPrice = $product->getPrice();
            $session = Yii::$app->session;

            if(Yii::$app->user->identity){
                $add = new ProductCart();
                $add->product_id =  (int)$_POST['product_id'];
                $add->user_id =  (int)Yii::$app->user->identity->id;
                $add->qty =  (int)$_POST['qty'];
                $add->save(false);
            }else{
                $add = new ProductCart();
                $add->product_id =  (int)$_POST['product_id'];
                $add->user_id =  $_POST['user'];
                $add->qty =  (int)$_POST['qty'];
                $add->save(false);
            }
            if ($flag == 1) {
                $flag2 = 0;
                if (isset($_POST['specVal']) and ! empty($_POST['specVal'])) {
                    foreach ($session['cart'] as $key2 => $productArray) {
                        if (array_diff($_SESSION['cart'][$key2]['specifications'], $_POST['specVal']) === array_diff($_POST['specVal'], $_SESSION['cart'][$key2]['specifications']) and $_POST['product_id'] == $productArray['product_id']) {
                            $flag2 = 1;
                            $productKey2 = $key2;
                            break;
                        }
                    }
                }
