Prestashop 1.4購物車更新問題（貨幣換算）

Question

我在執行$ cart-> update（）時遇到一個奇怪的問題； 更改貨幣后

例如，以磅為單位，購物車的總金額為£896.32 ，當前匯率為1.388889 （歐元）

因此，以歐元計算，應為896.32 * 1.388889 = 1244.89（四舍五入）

但是，如果我在結帳和付款模塊上，我會：

$cookie->id_currency = 1; //1 for EUR
$cart->id_currency = $cookie->id_currency;
$cart->update();
//and then...
$amount = number_format($cart->getOrderTotal(true, 3), 2, '.', '');

它完全出錯了……最后的$ total變量是錯誤的。

調試控制台： $ cart-> update（）之前；

$cart   Smarty_Variable Object (3)
->value = Cart Object (14)
   ->id = 2899
   ->id_address_delivery = "5"
   ->id_address_invoice = "5"
   ->id_currency = "3"
   ->id_customer = "3"
   ->id_guest = "998683"
   ->id_lang = "1"
   ->id_carrier = "14"
   ->recyclable = "1"
   ->gift = "0"
   ->gift_message = ""
   ->date_add = "2015-12-09 10:08:27"
   ->secure_key = "5b5c81dbecc7b7e1d9603752071321b7"
   ->date_upd = "2015-12-09 17:17:15"
->nocache = false
->scope = "Smarty root"


$total  Smarty_Variable Object (3)
->value = "£896.32"
->nocache = false
->scope = "Smarty root"

$ cart-> update（）之后；

$cart   Smarty_Variable Object (3)
->value = Cart Object (14)
   ->id = 2899
   ->id_address_delivery = "5"
   ->id_address_invoice = "5"
   ->id_currency = 1
   ->id_customer = "3"
   ->id_guest = "998683"
   ->id_lang = "1"
   ->id_carrier = "14"
   ->recyclable = "1"
   ->gift = "0"
   ->gift_message = ""
   ->date_add = "2015-12-09 10:08:27"
   ->secure_key = "5b5c81dbecc7b7e1d9603752071321b7"
   ->date_upd = "2015-12-09 17:19:41"
->nocache = false
->scope = "Smarty root"

$total  Smarty_Variable Object (3)
->value = "1 239,67 €"
->nocache = false
->scope = "Smarty root"

如您所見，這1 239,67€是錯誤的，應該改為1 244,89€ 。

拜托，錯誤在哪里？ 我為此而瘋狂。 非常感謝您的幫助。

發現了這個問題

在數據庫中有一個extra_shipping_cost字段，當您更改幣種時該字段不會更新。 我不知道在最新的PS版本中行為是否有所不同，但這肯定是開發人員的疏忽。
