Magento：在AJAX响应中获取所有更新的购物车项目数据

我的购物车与弹出窗口类似：

我通过AJAX调用一次更新购物车中具有自定义选项的多个可配置项目

但我无法将所有项目数据返回到AJAX响应

我得到的只是第一个项目的价格和rowTotal。对于其余项目，itemPrice和rowTotal设置为0

代码：

public function updateItemOptionsAction()
{
    $cartData = $this->getRequest()->getParam('cart');
    Mage::log($cartData);
    if (is_array($cartData)) {
        $result = array();
        $result['data'] = array();
        foreach ($cartData as $index => $data) {
            $cart   = $this->_getCart();
            $params = $data;
            $id = (int)$data['id'];

            if (!isset($params['options'])) {
                $params['options'] = array();
            }
            $result['data'][$index] = array();
            $oldQty = null;
            $kitType = $params['efk_kType'];
            $params['super_attribute'] = array($data['sAttr']=>$kitType);
            unset($params['sAttr']);
            $stock = null;
            try {
                if (isset($params['qty'])) {
                    $product = Mage::getModel("catalog/product")->load($params['product']);
                    $childProducts = Mage::getModel('catalog/product_type_configurable')->getUsedProducts(null, $product);
                    foreach($childProducts as $cProd){
                        if($cProd->getKitType() == $kitType){
                            $stock = intval(Mage::getModel('cataloginventory/stock_item')->loadByProduct($cProd)->getQty());
                        }
                    }
                    if(intval($params['qty']) > $stock){
                        $oldQty = intval($params['qty']);
                        $params['qty'] = $stock;
                        $result['data'][$index]['revised'] = true;
                    }

                    $filter = new Zend_Filter_LocalizedToNormalized(
                        array('locale' => Mage::app()->getLocale()->getLocaleCode())
                    );
                    $params['qty'] = $filter->filter($params['qty']);
                }

                $quoteItem = Mage::getSingleton('checkout/cart')->getQuote()->getItemById($id);
                if (!$quoteItem) {
                    Mage::throwException($this->__('Quote item is not found.'));
                }

                //Its going to infinity loop duwe to Varien Object need to check later
                //$item = $cart->updateItem($id, new Varien_Object($params));
                $item = Mage::getSingleton('checkout/cart')->updateItem($id, $params);

                if (is_string($item)) {
                    Mage::throwException($item);
                }
                if ($item->getHasError()) {
                    Mage::throwException($item->getMessage());
                }
                Mage::log('hi2');

                $related = $params['related_product'];
                if (!empty($related)) {
                    Mage::getSingleton('checkout/cart')->addProductsByIds(explode(',', $related));

                    array('item' => $item, 'request' => $this->getRequest(), 'response' => $this->getResponse())
                );
                $cart->getQuote()->setTotalsCollectedFlag(false);
                Mage::getSingleton('checkout/cart')->init();

                        if($oldQty > $item->getQty()){
                            $message = $this->__('%s has been revised due to stock limitations. You may proceed with the order for the revised quantity.', Mage::helper('core')->escapeHtml($item->getProduct()->getName()));
                        }else{
                            $message = $this->__('%s was updated in your shopping cart.', Mage::helper('core')->escapeHtml($item->getProduct()->getName()));

        $totals = Mage::getSingleton('checkout/cart')->getQuote()->getTotals();
        $result['data']['subTotal'] = Mage::helper('checkout')->formatPrice($totals['subtotal']->getValue());
        if(isset($totals['discount']) && $totals['discount']->getValue()){
            $result['data']['discount'] = Mage::helper('checkout')->formatPrice($totals['discount']->getValue());
        }else{
            $result['data']['discount'] = Mage::helper('checkout')->formatPrice(0);
        }
    }
    $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
}

我得到了AJAX响应

{
    "data": {
        "1187": {
            "success": true,
            "message": "THREE PHASE SOLID STATE RELAY WITH ZVS was updated in your shopping cart.",
            "itemId": "1191",
            "itemPrice": "<span class=\"price\">20b9  3,799</span>",
            "qty": 1,
            "rowTotal": "<span class=\"price\">20b9  3,799</span>",
            "forLoop": "yes"
        },
        "1189": {
            "success": true,
            "message": "AUTO INTENSITY CONTROL OF STREET LIGHTS was updated in your shopping cart.",
            "itemId": "1193",

            "qty": 1,
            "rowTotal": "<span class=\"price\">20b9  0</span>",
            "forLoop": "yes"
        },
        "grandTotal": "<span class=\"price\">20b9  8,798</span>",
        "totalItems": 2,
        "subTotal": "<span class=\"price\">20b9  8,798</span>",
        "discount": "<span class=\"price\">20b9  0</span>"
    }
}

{
“数据”：{
"1187": {
“成功”：没错，
“消息”：“带ZVS的三相固态继电器已在您的购物车中更新。”，
“itemId”：“1191”，
“项目价格”：“20b9 3799”，
“数量”：1，
“rowTotal”：“20b9 3799”，
“forLoop”：“是”
},
"1189": {
“成功”：没错，
“消息”：“您的购物车中的路灯自动亮度控制已更新。”，
“itemId”：“1193”，
“项目价格”：“20b9 0”，
“数量”：1，
“rowTotal”：“20b9 0”，
“forLoop”：“是”
},
“总计”：“20b9 8798”，
“总计项目”：2，
“小计”：“20b9 8798”，
“折扣”：“20b9 0”
}
}

我将第二个项目的itemPrice和rowTotal设置为0。每次我只得到第一项的正确值。如果我一次更新5个项目（例如），那么第一个项目的值是正确的，而重新定义项目的值是0

如果我在得到AJAX响应后刷新购物车，那么它将正确显示所有项目的itemPrice和rowTotal更新值

注：20b9是印度卢比符号的十六进制代码

请指出我错在哪里

提前谢谢。

你工作太努力了。。。尝试更新控制器服务器端的项目，保存当前报价。。。然后有一个控制器方法，加载当前的.phtml并将html作为cart块的json返回，然后用新的块替换整个cart html块（div）

在控制器方法的末尾

$this->getResponse()->setBody( json_encode(
array("html" => 
            Mage::app()->getLayout()->createBlock('checkout/[[whatevertag_is_to_cart_div phtml block]]')->toHtml()
     )
);

我没听懂你的话。如果可能，请用代码向我解释。我是magento的新手。现在有意义了吗？购物车中的项目更新是否正确，而您在ajax响应中只得到错误的数据，以便再次重新填充购物车弹出窗口？
