Class 'Braintree_Gateway' not found

[petlys]

General information

• SDK/Library version: 3.38.0
• Environment: Sandbox

Issue description

I've downloaded your library directly (i.e from https://developers.braintreepayments.com/client_libraries/php/braintree-php-3.38.0.tgz)

Extracted all the contents of the lib folder into a braintree folder, and created a doPayment.php script as follows:

<?php
require_once './braintree/Braintree.php';

header('Content-type: Application/JSON');

$amount = $_POST["amount"];
$nonce = $_POST["nonce"];

$gateway = new Braintree_Gateway([
    'environment' => 'sandbox',
    'merchantId' => 'my_merchantId_goes_here',
    'publicKey' => 'my_publicKey_goes_here',
    'privateKey' => 'my_privateKey_goes_here'
]);

$result = $gateway->transaction()->sale([
  'amount' => $amount,
  'paymentMethodNonce' => $nonce,
  'options' => [ 'submitForSettlement' => true ]
]);

if ($result->success) {
  http_response_code(200);
  echo json_encode(array("data" => $result->transaction->id));
} else if ($result->transaction) {
  $message = $result->transaction->processorResponseText;
  $code = $result->transaction->processorResponseCode;
  $response = "Error processing transaction.\nCode: $code\nMessage: $message";
  http_response_code(503);
  echo json_encode(array("data" => $result->transaction->id));
} else {
  http_response_code(503);
  echo json_encode(array("data" => $result->errors->deepAll()));
}
?>

But I keep getting Class not found errors, e.g Class 'Braintree_Gateway' not found. Been a long time since I did anything in PHP, so might just be a silly mistake somewhere...

I was able to reproduce the error you are seeing. It's being caused because you need the whole package, not just the lib directory. I believe the autoload.php file won't work properly if you pull out just the lib directory.

After I included the whole thing, it worked just fine.

If you still have issues with your integration after that, please contact our support team.

Hey, I installed the library via composer composer require braintree/braintree_php and get the same error. I just can't find the Braintree_Gateway class anywhere, not sure what you meant by "the whole thing".

[crookedneighbor]

Have you run the install command? https://developers.braintreepayments.com/start/hello-server/php#or-use-composer

Please reach out to our support team so we can troubleshoot your specific integration https://help.braintreepayments.com

Yeah I did. I found this in the Gateway.php Class class_alias('Braintree\Gateway', 'Braintree_Gateway'); So I just used the Gateway class instead, and it got me a token, so it seems to work. Thanks.

If you download the library directly, then you don't need the whole thing, just the lib folder. My issue was that the autoload.php file referenced the wrong folder.
