Configuration

PangalinkBundle configuration is stored in app/config/config.yml file. An example is provided below:

t_fox_pangalink:
    accounts:
        #First bank
        #ID of the first bank. This ID will be used in system. Feel free to write any ID you wish
        swedbank:
            #Type of bank. Possible arguments: swedbank, seb, krediidipank, sampo, nordea, lhv
            bank: swedbank
            #Service URL. Remove in production mode if real bank's URL is necessary
            service_url: "https://pangalink.net/banklink/swedbank"
            #Vendor's bank account number
            account_number: 123456
            #Vendor's name
            account_owner: "Test"

            #Route of the page displayed if payment was cancelled
            route_cancel: "acme_demo_pangalink_swedbank_index"
            #Alternatives to route_return and route_cancel are:

            route_cancel: "acme_demo_pangalink_nordea_index"

Usage

• First of all let's create an action where payment data will be saved

//YourBundle/Controller/SomeController.php

use Sensio\Bundle\FrameworkExtraBundle\Configuration as Sensio;

class SomeController extends BaseController
{

    /**
     * @Sensio\Route
     * @Sensio\Template
     */
    public function indexAction()
    {
        //Amount, payment description and some transaction ID
        $amount = 10.0;
        $description = 'Symfony2 pangalink bundle test';
        $transactionId = mt_rand(0, 999999);
        $transactionId = str_pad($transactionId, 6, '0');

        /* @var $service \TFox\PangalinkBundle\Service\PangalinkService */
        $service = $this->get('tfox.pangalink.service');
         // 'swedbank' is ID of the bank from config.yml
        /* @var $connector \TFox\PangalinkBundle\Connector\SwedbankConnector */     
        $connector = $service->getConnector('swedbank');
        $request = $connector->createPaymentRequest();
        $request
            ->setAmount($amount)
            ->setComment($description)
            ->setTransactionId($transactionId)
            ->setLanguage('EST') //Possible values: EST, ENG, RUS
            // Warning: RUS is not applicable for Nordea
        ;

        // Warning: date is not applicable for Solo protocol (Nordea)
        $request->setDateTime(new \DateTime());

        //Optional. Warning: don't forget to make a 7 + 3 + 1 check of reference number,
        //otherwise bank might not accept sended data
        //Further info: http://www.pangaliit.ee/et/arveldused/7-3-1meetod
        //->setReferenceNumber('123456')
        ;

        return array('payment_request' => $request);

    }
}

• Now you can render your form. You have two ways of doing it. The first way allows you to make any design of the form you want:

//YourBundle/Resources/views/Some/index.html.twig

{# 'swedbank' is bank ID which was defined in config.yml  #}
<form method="post" action="{{ pangalink_action_url(payment_request) }}">
{{ pangalink_form_data(payment_request) }}

{# Just an argument from controller  #}

<input type="submit" value="Begin payment">
</form>

• The second way displays a graphic button which redirects to bank if clicked. Here you can see five different rendered buttons:

//YourBundle/Resources/views/Some/index.html.twig

{# The first argument is a payment request received from controller. The second argument is a button code. Watch the table below.  #}

{{ pangalink_button(payment_request, '88x31') }}

In the table below are provided codes for images which are available in PangalinkBundle.
WARNING! All images are the property of their respective owners (banks). It is usually forbidden to modify provided images.

• The last task is to process a response which was sent by bank. Let's look to controller again:

//YourBundle/Controller/SomeController.php

use Sensio\Bundle\FrameworkExtraBundle\Configuration as Sensio;

class SomeController extends BaseController
{

    /**
     * @Sensio\Route("/process")
     * @Sensio\Template
     */
    public function processAction(Request $request)
    {
            /* @var $service \TFox\PangalinkBundle\Service\PangalinkService */
            $service = $this->get('tfox.pangalink.service');
            // Get a response from bank. 
            // The bundle automatically determines an appropriate connector
            $paymentResponse = $service->getPaymentResponse($request);

            // If no appropriate connector found, the function "getPaymentResponse" returns null
            if(true == is_null($paymentResponse))
                throw new \Exception('Could not determine a bank operator');

            // Check if payment was successful
            if(true == $paymentResponse->isSuccessful()) {
                // Get some properties 
                $paymentResponse->getBankId();
                $paymentResponse->getOrderNumber();
                $paymentResponse->getTransactionId();
                $paymentResponse->getDateTime();
            }

            // Get ID of the connector defined in the Symfony confiruration
            $accountId = $paymentResponse ? $paymentResponse->getConnector()->getAccountId() : 'NONE';
            // Format status
            $status = $paymentResponse && $paymentResponse->isSuccessful() ? 'YES' : 'NO';

            return array(
                'response' => $paymentResponse,
                'account_id' => $accountId,
                'status' => $status
            );
    }
}
