我有一位观察员,如果他们缺货(即顾客返回购物车x次,并且购物车中的物品已缺货),则从购物车中移除商品,以及向用户显示消息。Magento在观察员中重新计算购物车总计
删除项目工作正常,但更新购物车总额不。任何帮助将不胜感激!
我的观察者观察sales_quote_save_before事件:
public function checkStockStatus($observer)
{
// return if disabled or observer already executed on this request
if (!Mage::helper('stockcheck')->isEnabled() || Mage::registry('stockcheck_observer_executed')) {
return $this;
}
$quote = $observer->getEvent()->getQuote();
$outOfStockCount = 0;
foreach ($quote->getAllItems() as $item) {
$product = Mage::getModel('catalog/product')->load($item->getProductId());
$stockItem = $product->getStockItem();
if ($stockItem->getIsInStock()) {
// in stock - for testing only
$this->_getSession()->addSuccess(Mage::helper('stockcheck')->__('in stock'));
$item->setData('calculation_price', null);
$item->setData('original_price', null);
}
else {
//remove item
$this->_getCart()->removeItem($item->getId());
$outOfStockCount++;
$this->_getSession()->addError(Mage::helper('stockcheck')->__('Out of Stock'));
}
}
if ($outOfStockCount) > 0) {
$quote->setTotalsCollectedFlag(false)->collectTotals();
}
Mage::register('stockcheck_observer_executed', true);
return $this;
}
protected function _getCart()
{
return Mage::getSingleton('checkout/cart');
}
protected function _getSession()
{
return Mage::getSingleton('checkout/session');
}
你可以接受答案,然后让别人知道它已经解决了 –
