我有一个捆绑了WordPress主题的脚本。我想把货币从美元改为英镑。主题控制面板中有一个设置，但在结账时不会反映出来。
PayPal技术支持已经查看并返回以下内容：
paymentrequest_0_currencycode已成功传递给SetExpressCheckoutAPI请求（paymentrequest_0_currencycode“GBP”），但它根本未传递给DoExpressCheckoutPaymentAPI请求，因此结果事务失败， ：
errorcode 10444 shortmessage "Transaction refused because of an invalid argument. See additional error messages for details." longmessage "The transaction currency specified must be the same as previously specified."要解决此问题，您必须检查
DoExpressCheckoutPaymentAPI请求，并确保通过paymentrequest_0_currencycode=GBP。
但我不确定应该应用此修复程序的位置我尝试将其添加到DoExpressCheckoutPayment函数中但没有成功。这是完整的脚本。任何提示都会很棒。

看看$fields和StartExpressCheckout()中DoExpressCheckout()数组之间的差异，您会发现后者缺少'PAYMENTREQUEST_0_CURRENCYCODE'。您可以通过将$fields中的DoExpressCheckout()数组修改为以下内容来解决此问题：
global $redux_demo;
$currency_code = $redux_demo['currency-code'];
// FIELDS
$fields = array(
'USER' => urlencode($paypal_api_username),
'PWD' => urlencode($paypal_api_password),
'SIGNATURE' => urlencode($paypal_api_signature),
'VERSION' => urlencode('72.0'),
'PAYMENTREQUEST_0_PAYMENTACTION' => urlencode('Sale'),
'PAYMENTREQUEST_0_CURRENCYCODE' => $currency_code,
'PAYERID' => urlencode($result['PAYERID']),
'TOKEN' => urlencode($result['TOKEN']),
'PAYMENTREQUEST_0_AMT' => urlencode($result['AMT']),
'METHOD' => urlencode('DoExpressCheckoutPayment')
);
