我正在向 WP Woocommerce 添加自定义支付网关。 我想获取创建的购物车的当前用户 order_id。
我可以获得购物车总数：
global $woocommerce;
$total= $woocommerce->cart->total ;
或与：
WC()->cart->get_total() ;
如何调用函数：
process_payment($order_id)
当我还没有 $order_id 而我只有购物车时？
（错误的问题：还没有order_id）
【问题讨论】：
标签： wordpress woocommerce payment-gateway
最初提出的问题的答案是：
您的购物车中还没有订单 ID。 只有结帐完成后，订单 ID 才存在。
答案与问题不相符，可能需要再次询问或编辑。
【讨论】：
add_action('woocommerce_payment_complete', 'custom_process_order', 10, 1);
function custom_process_order($order_id) {
$order = new WC_Order( $order_id );
$myuser_id = (int)$order->user_id;
$user_info = get_userdata($myuser_id);
$items = $order->get_items();
foreach ($items as $item) {
if ($item['product_id']==24) {
// Do something clever
}
}
return $order_id;
}
这将挂钩到 WooCommerce 以在下订单后触发 custom_process_order

如何创建自定义支付网关？
您是否创建了扩展 WC_Payment_Gateway 的类，
你不需要直接调用process_payment()函数。
您只需要创建扩展WC_Payment_Gateway 的类并将该函数添加到您的类中，它将自动从结帐过程中调用
见woocommerce/includes/class-wc-checkout.php线777
process_payment() 函数应该返回一个带有键 results 和 redirect_url 的数组
示例：
public function process_payment( $order_id ) {
$order = wc_get_order( $order_id );
// Set order status
$order->update_status( 'processing', __( 'Payment created from custom gateway' ) );
// Reduce stock levels
wc_reduce_stock_levels( $order_id );
// Remove cart
WC()->cart->empty_cart();
// Return thankyou redirect
return array(
'result' => 'success',
'redirect' => $this->get_return_url( $order ),
);
}
【讨论】：
validate_fields() 验证它并返回bool（true 或false），或者在挂钩woocommerce_checkout_process 上检查它，您可以在class-wc-checkout.php 文件https://github.com/woocommerce/woocommerce/blob/master/includes/class-wc-checkout.php 上查看结帐过程的代码

收到付款后如何创建订单（notification.php 中的案例 ACCORD）???
【讨论】：
如果您的用户尝试付款但失败，您可能需要检查 $order_id = WC()->session->get( 'order_awaiting_payment' );
