pin payment error - vendor/autoload.php not found

Question

I have installed composer on my pc and running a pin payment script.

require_once __DIR__.'/vendor/autoload.php';
use Omnipay\Common\GatewayFactory;
$gateway = GatewayFactory::create('Pin');
$gateway->setSecretKey('1111111111');
$gateway->purchase(array(
    'email'       => 'abc.php2@gmail.com',
    'description' => 'Widgets',
    'amount'      => '49.99',
    'currency'    => 'USD',
    'card_token'  => $_REQUEST['card_token'],
    'ip_address'  => $_REQUEST['ip_address']
))->send();

I am not sure about require_once _ DIR _.'/vendor/autoload.php'; , where can i find the exact path for the same.

Answer 1

I think as you as "but where do I find the vendor" that you did not run the composer install command.

You have to run it in order to create the vendor dorectory and download the packages. Find out more in the documentation : http://getcomposer.org/doc/00-intro.md#using-composer

Basically, run:

composer install
