Question

我在magento面临问题。将产品添加到购物车时，它会成功添加一个项目，但是当我尝试添加另一个项目时，它会删除上一个项目并添加新项目。这是因为引号ID每次都会更改，关闭浏览器或其他任何内容。

知道如何解决此问题吗？

你可以在这个函数中调试

app \ code \ core \ Mage \ Checkout \ Model \ Cart.php

找到这个功能

 public function save()
{
    Mage::dispatchEvent('checkout_cart_save_before', array('cart'=>$this));

    $this->getQuote()->getBillingAddress();
    $this->getQuote()->getShippingAddress()->setCollectShippingRates(true);
    $this->getQuote()->collectTotals();
    $this->getQuote()->save();
    $this->getCheckoutSession()->setQuoteId($this->getQuote()->getId());
    /**
     * Cart save usually called after changes with cart items.
     */
    Mage::dispatchEvent('checkout_cart_save_after', array('cart'=>$this));
    return $this;
}

你可以在这里调试。希望这会对你有所帮助。

我已为自定义价格编辑此代码

      public function save()
                          {
            Mage::dispatchEvent('checkout_cart_save_before', array('cart'=>$this));
        $this->getQuote()->getBillingAddress();
                    $this->getQuote()->getShippingAddress()->setCollectShippingRates(true);
                    $this->getQuote()->collectTotals();

                   // $this->getQuote()->save();
                    if(isset($_POST['product']))
                    $pid=$_POST['product'];

                    if(isset($_POST['npn']))
                    $new_price=$_POST['npn'];

                    foreach($this->getQuote()->getAllItems() as $item) {    
                        $productId = $item->getProductId();     
                        $product = Mage::getModel('catalog/product')->load($productId);
                        if(isset($pid))
                        {
                        if($productId==$pid)
                        {
                        if(isset($_POST['npn']) && $_POST['npn']!='')
                        {
                        $price = $_POST['npn'];
                        $item->setCustomPrice($price);
                        // we need this since Magento 1.4
                        $item->setOriginalCustomPrice($price);
                        }
                        }
                        }
                    }  
                    $this->getQuote()->save();
                    $this->getCheckoutSession()->setQuoteId($this->getQuote()->getId());
                    /**
                     * Cart save usually called after changes with cart items.
                     */
                    Mage::dispatchEvent('checkout_cart_save_after', array('cart'=>$this));
                    return $this;
                }

希望它会帮助你!!!
