405 * Jumbled up function.
407 * The purpose of this function is to transition a pending transaction to Completed including updating any
410 * It has been overloaded to also add recurring transactions to the database, cloning the original transaction and
411 * updating related entities.
413 * It is recommended to avoid calling this function directly and call the api functions:
414 * - contribution.completetransaction
415 * - contribution.repeattransaction
417 * These functions are the focus of testing efforts and more accurately reflect the division of roles
418 * (the job of the IPN class is to determine the outcome, transaction id, invoice id & to validate the source
419 * and from there it should be possible to pass off transaction management.)
421 * This function has been problematic for some time but there are now several tests via the api_v3_Contribution test
422 * and the Paypal & Authorize.net IPN tests so any refactoring should be done in conjunction with those.
424 * This function needs to have the 'body' moved to the CRM_Contribute_BAO_Contribute class and to undergo
425 * refactoring to separate the complete transaction and repeat transaction functionality into separate functions with
426 * a shared function that updates related components.
428 * Note that it is not necessary payment processor extension to implement an IPN class now. In general the code on the
429 * IPN class is better accessed through the api which de-jumbles it a bit.
431 * e.g the payment class can have a function like (based on Omnipay extension):
433 * public function handlePaymentNotification() {
434 * $response = $this->getValidatedOutcome();
435 * if ($response->isSuccessful()) {
437 * // @todo check if it is a repeat transaction & call repeattransaction instead.
438 * civicrm_api3('contribution', 'completetransaction', array('id' => $this->transaction_id));

441 * if (!stristr($e->getMessage(), 'Contribution already completed')) {
442 * $this->handleError('error', $this->transaction_id . $e->getMessage(), 'ipn_completion', 9000, 'An error may
443 * have occurred. Please check your receipt is correct');
444 * $this->redirectOrExit('success');
446 * elseif ($this->transaction_id) {
