            $quote = Mage::getModel('checkout/cart')->getQuote();
            $_cartItems = $quote->getAllVisibleItems();
            
            foreach ($_cartItems as $_cartItem) {
                $productId = $_cartItem->getData('product_id');               
                                          
                $_cartItem->setOriginalCustomPrice($newprice);
            }
            $quote->collectTotals();
            $quote->save();


注意:如果使用sales_quote_add_item这个observer,代码如下

public function updatePrice( $observer ){

        $event = $observer->getEvent();

        $quote_item = $event->getQuoteItem();

        $new_price = 200;
        $quote_item->setOriginalCustomPrice($new_price);
        $quote_item->setTotalPrice(350);

}

逐行解释这段代码:$(".add-to-cart-btn").click(function() { var itemId = $(this).data("id"); var itemName = $(this).data("name"); var itemPrice = $(this).data("price"); $.ajax({ type: "POST", url: "add-to-cart.php", data: { id: itemId, name: itemName, price: itemPrice } }).done(function(response) { alert(response); }); }); session_start(); $itemId = $_POST["id"]; $itemName = $_POST["name"]; $itemPrice = $_POST["price"]; if (!isset($_SESSION["cart"])) { $_SESSION["cart"] = array(); } array_push($_SESSION["cart"], array("id", $itemId, "name", $itemName, "price", $itemPrice)); echo "添加商品成功!"; $(document).on("click", ".remove-item-btn", function() { var itemId = $(this).data("id"); $.ajax({ type: "POST", url: "remove-from-cart.php", data: { id: itemId } }).done(function(response) { location.reload(); }); }); session_start(); $itemId = $_POST["id"]; foreach ($_SESSION["cart"] as $key => $item) { if ($item["id"] == $itemId) { unset($_SESSION["cart"][$key]); } } echo "删除商品成功!"; $(".checkout-btn").click(function() { var selectedItems = $(".cart-item:checked"); var totalPrice = 0; selectedItems.each(function() { var itemPrice = $(this).parents(".cart-item-row").find(".item-price").text(); var itemQty = $(this).parents(".cart-item-row").find(".item-qty").val(); var subTotal = itemPrice * itemQty; totalPrice += subTotal; }); window.location.href = "checkout.php?id=" + selectedItems.serialize() + "&total=" + totalPrice; }); session_start(); $selectedIds = explode("&", $_GET["id"]); foreach ($selectedIds as $key => $value) { $selectedIds[$key] = substr($value, strpos($value, "=") + 1); } $totalPrice = $_GET["total"];
