    return $gateways;
}
add_filter('woocommerce_payment_gateways', 'register_paypal_hosted_gateway');

class WC_PayPal_Hosted_Gateway extends WC_Payment_Gateway {
    public function __construct() {
        $this->id = 'paypal_hosted';
        $this->method_title = __('PayPal Hosted Payment', 'woocommerce');
        $this->supports = array('products');
    }

    public function process_payment($order_id) {
        $order = wc_get_order($order_id);
        return array(
            'result'   => 'success',
            'redirect' => $this->get_paypal_redirect_url($order),
        );
    }

    private function get_paypal_redirect_url($order) {
        $return_url = site_url('/thank-you');
        return "https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=your_paypal_email&amount=" . $order->get_total() . "&currency_code=USD&return=$return_url";
    }
}

Step 5: Activate and Test the Plugin
