A payment module is a regular PrestaShop module, except that it extends the
PaymentModule class instead of the
class MyOWnPaymentMethod extends PaymentModule
It can be attached to the following hooks:
payment: to display the payment method.
paymentReturn: to display the payment confirmation.
The handling of the payment itself is done through a controller or a remote server.
If you are using a remote server, a return URL makes it possible to execute a script from your module's folder in order to validate and register the payment.
In order to register the payment validation, you must use the
validateOrder() method from the
PaymentModule class, using the following parameters:
(integer) id_cart: the ID of the cart to validate.
(integer) id_order_state: the ID of the order status (Awiting payment, Payment accepted, Payment error, etc.).
(float) amount_paid: the amount that the client actually paid.
(string) payment_method: the name of the payment method.
Here are a few basic rules:
Check that the module is activated:
if (!$this->active) return;
