1. Install Payment Plugins for Stripe WooCommerce Plugin

   • Supports coexistence of multiple payment gateways
   • Settings → Payments → Enable "Multi Gateway Mode"

function thai_payment_gateway_rules($gateways){

    if(WC()->customer->get_billing_country() === 'TH'){

        unset($gateways['paypal']); //对泰国客户隐藏PayPal

    }

    

    $cart_total = WC()->cart->total;

    if($cart_total > 5000){ //大额订单只显示银行转账

        return ['kbank_transfer' => $gateways['kbank_transfer']];

    }

    

    return $gateways;

}

B. PromptPay QR Code Advanced Integration

1. Dynamic QR code generation programme:

   • Real-time generation of Bank of Thailand-compliant QR codes using ThaiQR PHP library

// checkout.js to add it:

jQuery(document).ready(function($){

    $('#promptpay-qr-container').qrCode({

        text: "00020101021129370016A00000067701011101130066"+merchantID+"53037645802TH6304",

        height: 200,

        colourDark : "#000000",
