If you look in the Mage_Catalog_Block_Product_List_Related::_prepareData method, you'll see that it is using the following code plus some house-keeping:
You could create your own Block that grabs the products from the cart, and loops through the same code. Something like:
$cartHelper = Mage::helper('checkout/cart');
$cart = $cartHelper->getCart();
$cartItems = $cart->getQuote()->getAllItems();
$relatedCollection = new Varien_Data_Collection();
foreach ($cartItems as $cartItem) {
$tempColl = $cartItem->getRelatedProductCollection();
... insert housekeeping code from Related block
... add $tempColl to $relatedCollection
}
you might need to deduplicate the collection (toArray() then array_unique) as it's possible that items in the cart have the same related products, but that should get you in the game at least.

要实现您的需求，只需添加“交叉销售”产品关系即可实现这一目标。

To achieve what you require simply adding "Cross Sell" product relationships will achieve this.

如果您查看
Mage_Catalog_Block_Product_List_Related::_prepareData方法，您会发现它使用以下代码以及一些内务处理：您可以创建自己的块来从购物车中获取产品，并且循环执行相同的代码。类似于：
您可能需要对集合进行重复数据删除（
toArray()然后array_unique），因为购物车中的商品可能具有相同的相关产品，但这应该可以帮助您至少在游戏中。哈特哈，
