Payment gateway and api client for Free Kassa service.
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist yarcode/yii2-free-kassa "~1.0"
or add
"yarcode/yii2-free-kassa": "~1.0"
to the require section of your composer.json.
Configure freeKassa component in the components section of your application.
'freeKassa' => [
'class' => '\yarcode\freekassa\Merchant',
'merchantId' => 'YOUR_MERCHANT_ID',
'merchantFormSecret' => 'SECRET_1',
'checkDataSecret' => 'SECRET_2',
'defaultCurrency' => 'DEFAULT_CURRENCY_ID',
'defaultLanguage' => 'ru' // or 'en'
],
To redirect user to PerfectMoney site you need to create the page with RedirectForm widget. User will redirected right after page load.
<?= \yarcode\freekassa\RedirectForm::widget([
'message' => 'Redirecting to payment gateway...',
'api' => Yii::$app->get('freeKassa'),
'invoiceId' => $invoice->id,
'amount' => $invoice->amount,
'description' => $invoice->description,
'email' => $invoice->owner->email
]); ?>
You will need to create controller that will handle result requests from PerfectMoney service. Sample controller code:
<?php
namespace frontend\controllers;
use common\models\Invoice;
use yii\base\Event;
use yii\helpers\ArrayHelper;
use yii\helpers\VarDumper;
use yii\web\Controller;
use yarcode\freekassa\actions\ResultAction;
use yarcode\freekassa\events\GatewayEvent;
use yarcode\freekassa\Merchant;
class PerfectMoneyController extends Controller
{
public $enableCsrfValidation = false;
protected $componentName = 'freeKassa';
public function init()
{
parent::init();
/** @var Api $pm */
$freeKassa = \Yii::$app->get($this->componentName);
$freeKassa->on(GatewayEvent::EVENT_PAYMENT_REQUEST, [$this, 'handlePaymentRequest']);
$freeKassa->on(GatewayEvent::EVENT_PAYMENT_SUCCESS, [$this, 'handlePaymentSuccess']);
}
public function actions()
{
return [
'result' => [
'class' => ResultAction::className(),
'componentName' => $this->componentName,
'redirectUrl' => ['/site/index'],
'sendConfirmationResponse' => true
],
'success' => [
'class' => ResultAction::className(),
'componentName' => $this->componentName,
'redirectUrl' => ['/site/index'],
'silent' => true,
'sendConfirmationResponse' => false
],
'failure' => [
'class' => ResultAction::className(),
'componentName' => $this->componentName,
'redirectUrl' => ['/site/index'],
'silent' => true,
'sendConfirmationResponse' => false
]
];
}
/**
* @param GatewayEvent $event
* @return bool
*/
public function handlePaymentRequest($event)
{
$invoice = Invoice::findOne(ArrayHelper::getValue($event->gatewayData, 'MERCHANT_ORDER_ID'));
if (!$invoice instanceof Invoice ||
$invoice->status != Invoice::STATUS_NEW ||
ArrayHelper::getValue($event->gatewayData, 'AMOUNT') != $invoice->amount ||
ArrayHelper::getValue($event->gatewayData, 'MERCHANT_ID') != \Yii::$app->get($this->componentName)->merchantId
)
return;
$invoice->debugData = VarDumper::dumpAsString($event->gatewayData);
$event->invoice = $invoice;
$event->handled = true;
}
/**
* @param GatewayEvent $event
* @return bool
*/
public function handlePaymentSuccess($event)
{
$invoice = $event->invoice;
// TODO: invoice processing goes here
}
