我正在为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。
我可以得到购物车总数：
global $woocommerce;
$total= $woocommerce->cart->total ;
或者：
WC()->cart->get_total() ;
我该如何调用该函数：
process_payment($order_id)
当我还没有$ order_id而且我只有购物车？
请帮忙。
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;
}
在下订单后，这将挂钩到WooCommerce以触发custom_process_order
你如何创建自定义支付网关？你创建了扩展WC_Payment_Gateway的类，你不需要直接调用process_payment()函数。
你只需要创建扩展WC_Payment_Gateway的类并在你的类上添加该函数，它将自动从checkout进程调用，参见woocommerce/includes/class-wc-checkout.php line 777
process_payment()函数应返回一个包含密钥results和redirect_url的数组
例如：
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 ),
);
}
我有一个使用文件自定义payment.php创建的插件，其中包含与付款提供商连接的表单：

收到付款后如何创建订单（在notification.php中为ACCORD）???
