CRM_Core_Payment_PaymentExpressIPN

^deprecated Jumbled up function. The purpose of this function is to transition a pending transaction to Completed including updating any related entities. It has been overloaded to also add recurring transactions to the database, cloning the original transaction and updating related entities. It is recommended to avoid calling this function directly and call the api functions: - contribution.completetransaction - contribution.repeattransaction These functions are the focus of testing efforts and more accurately reflect the division of roles (the job of the IPN class is to determine the outcome, transaction id, invoice id & to validate the source and from there it should be possible to pass off transaction management.) This function has been problematic for some time but there are now several tests via the api_v3_Contribution test and the Paypal & Authorize.net IPN tests so any refactoring should be done in conjunction with those. This function needs to have the 'body' moved to the CRM_Contribute_BAO_Contribute class and to undergo refactoring to separate the complete transaction and repeat transaction functionality into separate functions with a shared function that updates related components. Note that it is not necessary payment processor extension to implement an IPN class now. In general the code on the IPN class is better accessed through the api which de-jumbles it a bit. e.g the payment class can have a function like (based on Omnipay extension): public function handlePaymentNotification() { $response = $this->getValidatedOutcome(); if ($response->isSuccessful()) { try { // @todo check if it is a repeat transaction & call repeattransaction instead. civicrm_api3('contribution', 'completetransaction', array('id' => $this->transaction_id)); } catch (CiviCRM_API3_Exception $e) { if (!stristr($e->getMessage(), 'Contribution already completed')) { $this->handleError('error', $this->transaction_id . $e->getMessage(), 'ipn_completion', 9000, 'An error may have occurred. Please check your receipt is correct'); $this->redirectOrExit('success'); } elseif ($this->transaction_id) { civicrm_api3('contribution', 'create', array('id' => $this->transaction_id, 'contribution_status_id' => 'Failed')); }
