Here are the code of prepare and done action in controller:
public function preparePaypalAction(Request $request)
{
$paymentName = 'ibase_paypal_express_checkout';
$form = $this->createPurchaseForm();
$form->handleRequest($request);
if ($form->isValid()) {
$data = $form->getData();
$storage = $this->get('payum')->getStorage('Ibase\PaymentBundle\Entity\PaymentDetails');
/** #var \Ibase\CartBundle\Entity\PaymentDetails $paymentDetails */
$paymentDetails = $storage->createModel();
$paymentDetails['PAYMENTREQUEST_0_CURRENCYCODE'] = $data['currency'];
$paymentDetails['PAYMENTREQUEST_0_AMT'] = $data['amount'];//total amount ??
$storage->updateModel($paymentDetails);
$captureToken = $this->get('payum.security.token_factory')->createCaptureToken(
$paymentName,
$paymentDetails,
'payment_done' // the route to redirect after capture;
);
$paymentDetails['INVNUM'] = $paymentDetails->getId();
$paymentDetails['RETURNURL'] = $captureToken->getTargetUrl();
$paymentDetails['CANCELURL'] = $captureToken->getTargetUrl();
$storage->updateModel($paymentDetails);
return $this->redirect($captureToken->getTargetUrl());
}
return $this->render('PaymentBundle:PaypalExpress:paypalPrepare.html.twig', array(
'form' => $form->createView(),
'paymentName' => $paymentName
));
}
public function doneAction(Request $request)
{
$token = $this->get('payum.security.http_request_verifier')->verify($request);
$payment = $this->get('payum')->getPayment($token->getPaymentName());
$status = new BinaryMaskStatusRequest($token);
$payment->execute($status);
if ($status->isSuccess()) {
$this->getUser()->addCredits(100);
$this->get('session')->getFlashBag()->set(
'notice',
'Payment success. Credits were added'
);
} else if ($status->isPending()) {
$this->get('session')->getFlashBag()->set(
'notice',
'Payment is still pending. Credits were not added'
);
} else {
$this->get('session')->getFlashBag()->set('error', 'Payment failed');
}
return $this->redirect('home');
}
/**

*/
protected function createPurchaseForm()
{
return $this->createFormBuilder()
->add('amount', null, array(
'data' => 1,
'constraints' => array(new Range(array('max' => 2)))
))
->add('currency', null, array('data' => 'AUD'))
->getForm()
;
}
Anyone can help will be appreciate!

Answer 1

Look at your YML file
contexts:
Ibase_paypal_express:
and your code :
$paymentName = 'ibase_paypal_express_checkout';
Notice the capital 'I' and string name? Those two names/values should be the same.
So either
$paymentName = 'Ibase_paypal_express';
or
contexts:
ibase_paypal_express_checkout:
