如何在magento中添加新项目之前清除/删除购物车项目？

Question

我尝试使用以下代码删除/清除购物车商品,它已删除购物车中的所有商品.但未添加新商品/商品.

二手代码

1.Mage::getSingleton('checkout/session')->clear();
2.Mage::getSingleton('checkout/cart')->truncate();
3.$quote = Mage::getSingleton('checkout/session')->getQuote(); 
$quote->delete();
4.Mage::getSingleton('checkout/cart')->truncate()->save();
5.Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
6.foreach( Mage::getSingleton('checkout/session')->getQuote()->getItemsCollection() as $item ){
    Mage::getSingleton('checkout/cart')->removeItem( $item->getId() )->save();
}
7.$cartHelper = Mage::helper('checkout/cart');
        $items = $cartHelper->getCart()->getItems();       
        foreach ($items as $item)
        {
                $itemId = $item->getItemId();
                $cartHelper->getCart()->removeItem($itemId)->save();
        }

8.$quote = Mage::getSingleton('checkout/session')->getQuote();
$item = $quote->getItemByProduct($product);
$quote->removeItem($item->getId());

9.$quote->removeAllItems();

请任何人建议我以上我的要求.谢谢你提前.

这里是删除以及将产品添加到购物车的解决方案

$params['qty'] = 1;
$product = $this->_initProduct($_product); // here initialize the product

$cart = Mage::getModel('checkout/cart');                
$cart->truncate(); // remove all active items in cart page
$cart->init();
$cart->addProduct($product,$params);                        
$cart->save();
