UPDATE: You can also take a look at the paymentDemo module for some example code.
A payment always needs to have one data container which contains all information that the payment method needs to process the transaction. For example, in the case of a credit card payment, the data container would contain the credit card number, card holder, cvc number, and the expiration date. So, when you have collected this data from the customer, you can simply create a payment by calling the static
$payment = Payment::create(123.45, 'EUR', $paymentData);
Everytime, you want to change the state of a payment, you have to perform a transaction on it. Currently, the following transactions are available:
See also the State Flows for when you can perform which transaction on a payment.
In order to approve a payment, you have to perform an APPROVE transaction against it. Not all payment methods support APPROVE transactions, in these cases the approval is considered to be successful anyway. This is simply done by calling
performTransaction() on the payment:
$payment = Payment::create(123.45, 'EUR', $data); $payment->performTransaction(FinancialTransaction::TYPE_APPROVE);
If you only pass the transaction’s type to performTransaction(), it will make some assumptions as to which amount you would like to approve, and in which currency. If you want to set these values manually, you need to create the transaction yourself. But you don’t need to worry, FinancialTransaction also provides a neat static constructor for you:
$payment = Payment::create(123.45, 'EUR', $data); $transaction = FinancialTransaction::create( FinancialTransaction::TYPE_APPROVE, $payment, 100, 'USD' ); $payment->performTransaction($transaction);
As you have probably noticed, the approval transaction does neither cover the entire amount of the payment nor does it have the same currency as the payment. This is absolutely permissible as the payment system will use the current exchange rates to convert amounts accordingly (in order for this to work, you need to execute
php symfony jmsPaymentPlugin:updateRates via a daily cronjob).
You can perform multiple APPROVE transactions against a payment as long as the target amount of the payment has not been reached by these transactions. However, there can only be one open transaction at any given time.
