Razvoj prilagođenog Gateway-a

Možete kreirati prilagođene payment gateway-e ekstendiranjem klase Base_Gateway.

Klasa Gateway-a

class My_Custom_Gateway extends \WP_Ultimo\Gateways\Base_Gateway {

    public $id = 'my_gateway';

    public function __construct() {
        $this->title = 'My Payment Gateway';
        $this->description = 'Custom payment processing';
        $this->supports = ['one-time', 'recurring'];

        parent::__construct();
    }

    public function process_single_payment($payment, $cart, $order) {
        $result = $this->api_call('charge', [
            'amount' => $payment->get_total(),
            'currency' => $payment->get_currency(),
            'customer' => $payment->get_customer_id()
        ]);

        if ($result->success) {
            $payment->set_gateway_payment_id($result->transaction_id);
            $payment->set_status('completed');
            return true;
        }

        return new WP_Error('payment_failed', $result->error_message);
    }

    public function process_signup($membership, $customer, $cart, $order) {
        $subscription = $this->api_call('subscription/create', [
            'customer_id' => $customer->get_gateway_customer_id(),
            'plan_id' => $membership->get_plan()->get_gateway_plan_id(),
            'trial_days' => $membership->get_trial_days()
        ]);

        if ($subscription->success) {
            $membership->set_gateway_subscription_id($subscription->id);
            return true;
        }

        return new WP_Error('subscription_failed', $subscription->error);
    }
}

Registracija Gateway-a

add_filter('wu_payment_gateways', function($gateways) {
    $gateways['my_gateway'] = 'My_Custom_Gateway';
    return $gateways;
});

Ključne metode

Method	Purpose
process_single_payment()	Rukovanje jednokratnim plaćanjima
process_signup()	Postavljanje ponavljajućih pretplata
process_refund()	Rukovanje zahtjevima za povrat novca
get_payment_methods()	Vraćanje sačuvanih metoda plaćanja za klijenta

Savjeti

• Uvijek vratite WP_Error u slučaju neuspjeha kako bi Ultimate Multisite mogao obraditi prikaz greške.
• Postavite $this->supports kako biste deklarisali koje tipove plaćanja vaš gateway podržava (one-time, recurring).
• Koristite wu_log_add() za logovanje specifično za gateway.
