Magento:通过事件以编程方式更新购物车 [英] Magento: Programatically update cart via event
问题描述
我迷上了sales_quote_save_after
事件分配器.首先,作为测试,我试图将商品放入购物车并将其价格更改为0.这样做之后,我将使用其他一些商品.
I'm hooking into the sales_quote_save_after
event disaptcher. Firstly as a test I'm trying to get the items in the cart and change their prices to 0. After I do that I'll be building in some other stuff.
我遇到了麻烦.我可以更改单价没问题,但是当我重新计算购物车总额时,价格就会恢复为原始价格.
I'm having trouble. I can change the unit price no problem, but when I go to recalculate the cart totals the prices are reverting back to the original price.
public function sales_quote_save_before($observer) {
if (Mage::registry('basket_observer_executed')) {
return $this;
}
$quote = $observer->getEvent()->getQuote();
foreach ($quote->getAllItems() as $item) {
if($item->getId()) {
$item->setCustomPrice(0);
}
}
Mage::register('basket_observer_executed', true);
$quote->save();
$quote->setTotalsCollectedFlag(false)->collectTotals();
}
有人能指出我在重新计算总数的同时保持新价格吗?
Can anyone point me towards maintaining the new price whilst doing the recalculation of the totals?
推荐答案
我会尝试使用其他事件.我总是使用checkout_cart_save_after
来执行类似的操作.使用我提到的事件,使用以下代码:
I'd try using a different event. I always use checkout_cart_save_after
for doing similar actions.Using the event I mentioned, use the following code:
$cart = $observer->getData('cart');
$quote = $cart->getData('quote');
$items = $quote->getAllVisibleItems();
foreach($items as $item)
{
$item->setCustomPrice(0);
$item->setOriginalCustomPrice(0);
$item->getProduct()->setIsSuperMode(true);
$item->save();
}
$quote->save();
$quote->setTotalsCollectedFlag(false)->collectTotals();
