WooCommerce订单页面支付完成后更新订单元数据的钩子问题

Hey there, let's get this sorted for you!

The woocommerce_payment_successful_result hook you're using is actually designed to filter the success response sent back by the payment gateway. It fires pretty early in the payment flow—before the order's payment status is fully marked as completed. That's why it's triggering during the cart payment process instead of waiting for the payment to be fully successful.

To update your order meta only after payment is truly finalized and successful, you'll want to use a hook that triggers once the order's payment is confirmed complete. The best picks here are woocommerce_payment_complete or woocommerce_order_payment_complete—both fire exactly when the order's payment status is updated to "paid" (and the order shifts to processing or completed status, depending on your store settings).

Here's your revised code that will behave exactly as you need:

// Hook into the payment complete event
add_action( 'woocommerce_payment_complete', 'update_order_meta_on_payment_success', 10, 1 );

function update_order_meta_on_payment_success( $order_id ) {
    // Optional but recommended: Validate the order exists
    $order = wc_get_order( $order_id );
    if ( ! $order ) {
        return;
    }

    // Update your custom order meta data
    update_post_meta( $order_id, 'payments', 'example data' );

    // If you need to target specific order statuses (e.g., only "processing"), uncomment this block:
    // if ( $order->get_status() === 'processing' ) {
    //     update_post_meta( $order_id, 'payments', 'example data' );
    // }
}

Why this works better: #

• woocommerce_payment_complete fires only after the payment is fully processed and the order's status is updated. No more premature triggers during the initial cart payment flow.
• It's a dedicated action for payment completion, so you don't have to mess with filtering gateway responses or handling incomplete payment states.

If you need to target a specific payment gateway (like Stripe or PayPal), you can use gateway-specific hooks such as woocommerce_stripe_payment_complete—but the generic woocommerce_payment_complete should cover most standard use cases perfectly.
