我正在为woocommerce开发一个自定义支付网关，支付网关需要在处理付款之前进行注册，并且需要提交表单以重定向到网关的付款页面，用户将在其中提供他的卡详细信息。
需要使用表单提交重定向，因为必须传递我在注册调用中获得的事务ID和URL：
以下是我的支付网关的实际流程：
1-注册电话（必须通过orderID，金额，ReturnURL） 我在payment_fields（）函数中这样做，而不是将返回值放在隐藏的表单中。 2-重定向调用（必须以PortalURL为我的表单操作且TransactionID为隐藏字段的形式传递TransactionID，PortalURL）
这是我的支付网关类：

现在我的问题是，我在payment_fields（）函数中需要OrderID，OrderTotal和get_return_url（）。
我已经完成了以下所有方法，但没有一个适合我。

不工作：
global $wp;
$order_id = $wp->query_vars['order-pay'];
$order = new WC_Order( $order_id );
不工作：
get_query_var('order-pay');
任何人都可以帮我分类这个。因为我被困在这里。阅读woocommerce的所有文档并搜索堆栈溢出很多，但没有一个对我有用。
我正在使用最新版本的WooCommerce和WP。

我正在寻找类似的东西，但我担心你无法实现这一点，这是process_checkout方法的生命周期：
https://docs.woocommerce.com/wc-apidocs/source-class-WC_Checkout.html#895
如你所见@ line 928
$order_id = $this->create_order( $posted_data );
订单是在您即将付款时创建的，您之前无法获得订单。
答案 1 :(得分：1)
你不能像上一篇文章那样获得$ order_id，但你可以通过执行以下操作来检索payment_fields（）函数中购物车的货币和价值：
$currency = get_woocommerce_currency();
$value = max( 0, apply_filters( 'woocommerce_calculated_total', round( WC()->cart->cart_contents_total + WC()->cart->fee_total + WC()->cart->tax_total, WC()->cart->dp ), WC()->cart ) );
希望这有帮助
答案 2 :(得分：0)
我已经使用以下代码实现了它。
global $woocommerce;
$ordID = $woocommerce->session->order_awaiting_payment;
