PHP SDK - Call to confirmation email function breaks success message

Questions
1

Hi,

I’m sending a payment confirmation email to customers (currently in sandbox) for their payment. I have a mailer function added to process-payments.php and I am calling it if $response->isSuccess() just before the echo json_encode($response->getResult());. Here is the code snippet:

if ($response->isSuccess()) {
    sendConfirmationEmail();
    echo json_encode($response->getResult());
  } else {
    echo json_encode(array('errors' => $response->getErrors()));
  }

The payment is successful, and the email is sent, but the success message never appears on the payment page for the customer. What could be wrong?

The issue might be due to the sendConfirmationEmail() function. If this function is causing an error or exception, it could prevent the success message from being displayed. To debug this, you could try commenting out the sendConfirmationEmail() function call and see if the success message appears. If it does, then the issue is likely within the sendConfirmationEmail() function. You should then debug this function to find the exact cause of the issue.

Thanks. I found the issue. I had copied another email function that was part of a php ajax call anf it had an echo at the end, so that was overriding the echo for the success message. Everything is good now.
