Moneris-eSELECTplus-API

The PHP API Moneris supplies for eSelectPlus is a terrible mess that throws warnings like they were candy at a parade. This is a simple replacement for people who like PHP5, and hate errors.

Note: as of right now, I've only writting support for purchase, verify, pre-auth, capture, and refund operations. I've also included support for AVS/CVD verification.

Get Started

The first step is to set up your config, and get your Moneris gateway object:

$config = array(
    'api_key' => 'yesguy',
    'store_id' => 'store1',
    'environment' => Moneris::ENV_TESTING
);
$moneris = Moneris::create($config);

There are some handy optional params for the config as well:

$config = array(
    'api_key' => 'yesguy',
    'store_id' => 'store1',
    'environment' => Moneris::ENV_TESTING,
    // optional:
    'require_avs' => true, // default: false
    'avs_codes' => array('A','B', 'D', 'M', 'P', 'W', 'X', 'Y', 'Z'), // default
    'require_cvd' => true, // default: true
    'cvd_codes' => array('M', 'Y', 'P', 'S', 'U') // default
);

To make a purchase is pretty straight forward:

// set up $moneris like we did ^^ up there
$params = array(
    'cc_number' => '4242424242424242',
    'order_id' => 'test' . date("dmy-G:i:s"),
    'amount' => '20.00',
    'expiry_month' => date('m', $time),
    'expiry_year' => date('y', $time)
);
$result = $moneris->purchase($params);

The result object lets you know how everything went:

$result->was_successful(); // did the transaction work?
$result->failed_avs(); // did the transaction pass the AVS check?
$result->failed_cvd(); // did the transaction pass the CVD check?
$result->error_message(); // if something went wrong, what was it?

A common workflow might look like this:

$errors = array();
$result = $moneris->purchase($params);

if ($result->was_successful()) {
    // HOORAY! Party like it's 1999.
} else {
    $errors[] = $result->error_message();
}

There's one caveat though! If a transaction fails AVS/CVD, you still have to void it! An easy way to work around that is to verify the card first!

$errors = array();
$verification_result = $moneris->verify($params);

if ($verification_result->was_successful() && $verification_result->passed_avs() && $verification_result->passed_cvd()) {

    $purchase_result = $moneris->purchase($params);

    if ($purchase_result->was_successful()) {
        // HOORAY! Party like it's 1999.
    } else {
        $errors[] = $result->error_message();
    }

} 

Or:

$errors = array();
$purchase_result = $moneris->purchase($params);

if ($purchase_result->was_successful() && ( $purchase->failed_avs() || $purchase_result->failed_cvd() )) {
    $errors[] = $purchase_result->error_message();
    $void = $moneris->void($purchase_result->transaction());
} else if (! $purchase_result->was_successful()) {
    $errors[] = $purchase_result->error_message();
} else {
    // OMG we're rich!
}

You can view the transaction details via the transaction object.

$result = $moneris->purchase($params);
$transaction = $result->transaction();

You can learn some nift stuff from it, as well as see the XML returned by Moneris.

$transaction->number(); // receipt->TransID from the Moneris XML response
$transaction->amount(); // amount processed
$transaction->response(); // the SimpleXMLElement from the parsed Moneris response.

The capture, void, and refund methods can all accept a transaction object as the first param:

$result = $moneris->purchase($params);
$moneris->refund($result->transaction()); // refund the full purchase
$moneris->refund($result->transaction(), null, '5.00'); // refund $5.00
// OR
$moneris->refund($result->transaction()->number(), $params['order_id'], $params['amount']); // refund the full purchase
$moneris->refund($result->transaction()->number(), $params['order_id'], '5.00'); // refund $5.00

$result = $moneris->preauth($params);
$moneris->capture($result->transaction());
// OR
$moneris->capture($result->transaction()->number(), $params['order_id'], $params['amount']);

$result = $moneris->purchase($params);
$moneris->void($result->transaction());
// OR
$moneris->void($result->transaction()->number(), $params['order_id']);

Lemme know if you have any questions. @ironkeith on the Twitters.
