做到這一點(diǎn)的方法是添加一個(gè)觀察該事件的觀察者'sales_quote_add_item'：
<events>
<sales_quote_add_item>
<observers>
<priceupdate_observer>
<type>singleton</type>
<class>mymodule/observer</class>
<method>updatePrice</method>
</priceupdate_observer>
</observers>
</sales_quote_add_item>
</events>
觀察者應(yīng)具有執(zhí)行以下操作的方法：
public function updatePrice($observer) {
$event = $observer->getEvent();
$quote_item = $event->getQuoteItem();
$new_price = <insert logic>
$quote_item->setOriginalCustomPrice($new_price);
$quote_item->save();
}

您可以使用觀察者類來收聽checkout_cart_product_add_after，并使用產(chǎn)品的“超級(jí)模式”為報(bào)價(jià)項(xiàng)設(shè)置自定義價(jià)格。
在您的/app/code/local/{namespace}/{yourmodule}/etc/config.xml中：
<config>
...
<frontend>
...
<events>
<checkout_cart_product_add_after>
<observers>
<unique_event_name>
<class>{{modulename}}/observer</class>
<method>modifyPrice</method>
</unique_event_name>
</observers>
</checkout_cart_product_add_after>
</events>
...
</frontend>
...
</config>
然后在/app/code/local/{namespace}/{yourmodule}/Model/Observer.php中創(chuàng)建一個(gè)Observer類
<?php
class <namespace>_<modulename>_Model_Observer
{
public function modifyPrice(Varien_Event_Observer $obs)
{
$customPrice = Mage::getSingleton(’core/session’)->getCustomPriceCalcuation(); // Provide you price i have set with session
$p = $obs->getQuoteItem();
$p->setCustomPrice($customPrice)->setOriginalCustomPrice($customPrice);
}
}
