magento - 在观察者中获取简单产品的选定自定义选项价格

Question

如何在观察者中获取选定的自定义期权价格。我正在使用 checkout_cart_product_add_after 事件作为观察者和观察者代码:

public function applyCartPriceChange(Varien_Event_Observer $observer)
{

    $item     = $observer->getQuoteItem();
    $product  = $item->getProduct();
    $productOptions = $product->getTypeInstance(true)->getOrderOptions($product);
    echo '<pre>';
    print_r($productOptions);
    foreach($productOptions['options'] as $key=>$value){
        if($value['label'] !='Date'){
            echo $value['option_id'];
        }
    }
    exit;

    if ($specialPrice > 0) {
        $item->setCustomPrice($specialPrice);
        $item->setOriginalCustomPrice($specialPrice);
        $item->getProduct()->setIsSuperMode(true);
    }
}

我使用此代码获取所有选定的自定义选项详细信息，但不获取价格 $productOptions = $product->getTypeInstance(true)->getOrderOptions($product); 它打印数组，如下所示:

public function applyCartPriceChange(Varien_Event_Observer $observer)
{
    $item = $observer->getQuoteItem();
    $product = $item->getProduct();
    $productOptions = $product->getTypeInstance(true)->getOrderOptions($product);
    //echo '<pre>';
    //print_r($productOptions);exit;
    foreach ($productOptions['options'] as $key => $value) {

        $product = Mage::getModel("catalog/product")->load($product->getId()); //product id 1
        foreach ($product->getOptions() as $o) {
            $values = $o->getValues();
            if ($o->getTitle() == 'Adult') { //change your custom option title to compare
                foreach ($values as $v) {
                    if ($value['option_value'] == $v->getOptionTypeId()) {
                        $adultPrice = $v->getprice(); /* get price of custom option*/
                        $noOfAdult = $v->getTitle();
                    }
                }
