Setting Up Zend Framework

When building a custom e-commerce store with Zend Framework and Authorize.net, proper setup is crucial. Follow these steps to get started efficiently.

Installation Steps

Use Composer to install Zend Framework. Execute the following command:

composer require zendframework/zendframework

Verify the installation by checking the vendor directory for the zendframework folder. Edit the composer.json file to include autoload settings for your application:

"autoload": {
"psr-4": {
"Application\\": "module/Application/src/"
},
"classmap": [
"module/Application/src/"
]
}

Run composer dump-autoload to update the autoloader.

Configuring the Environment

Create the config/application.config.php file to register modules. Add the following code:

return [
'modules' => [
'Zend\\Router',
'Zend\\Validator',
'Application',
],
'module_listener_options' => [
'config_glob_paths'    => [
'config/autoload/{{,*.}global,{,*.}local}.php',
],
'module_paths' => [
'./module',
'./vendor',
],
],
];

Set file permissions for data and cache directories. Run:

chmod -R 0777 data
chmod -R 0777 cache

Configure the database in config/autoload/global.php:

return [
'db' => [
'driver'         => 'Pdo',
'dsn'            => 'mysql:dbname=your_db;host=localhost',
'username'       => 'your_username',
'password'       => 'your_password',
'driver_options' => [
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'',
],
],
];

With these steps, the Zend Framework should be installed and configured properly, setting a strong foundation for integrating Authorize.net and building your custom e-commerce store.

Integrating Authorize.net with Zend Framework

Integrating Authorize.net with Zend Framework is essential for secure and efficient payment processing. We outline the key steps for seamless integration below.

API Key Setup

To begin the integration, create an account with Authorize.net. After logging in, navigate to the API Credentials & Keys section in the Merchant Interface. Generate a new API key and store it securely. Use this key in your Zend Framework application.

Authorize.net provides two keys: API Login ID and Transaction Key. Add these keys to your Zend Framework configuration file. Ensure the keys are encrypted in storage. Example:

return [
'authorize_net' => [
'api_login_id' => 'your_api_login_id',
'transaction_key' => 'your_transaction_key',
],
];

Implementing Transaction Logic

Authorize.net transaction logic includes payment processing methods. First, install the Authorize.net SDK via Composer:

composer require authorizenet/authorizenet

Next, configure the SDK in the Zend Framework application by creating a service factory. Example:

namespace Application\Service\Factory;

use net\authorize\api\constants\ANetEnvironment;
use net\authorize\api\controller\CreateTransactionController;
use net\authorize\api\contract\v1 as AnetAPI;
use Zend\ServiceManager\Factory\FactoryInterface;

class AuthorizeNetServiceFactory implements FactoryInterface
{
public function __invoke($container, $requestedName, array $options = null)
{
$config = $container->get('config')['authorize_net'];
$merchantAuthentication = new AnetAPI\MerchantAuthenticationType();
$merchantAuthentication->setName($config['api_login_id']);
$merchantAuthentication->setTransactionKey($config['transaction_key']);

return new AuthorizeNetService($merchantAuthentication);
}
}

To process a transaction, create a method in your service class. Example:

namespace Application\Service;

use net\authorize\api\contract\v1 as AnetAPI;
use net\authorize\api\controller\CreateTransactionController;

class AuthorizeNetService
{
protected $merchantAuthentication;

public function __construct($merchantAuthentication)
{
$this->merchantAuthentication = $merchantAuthentication;
}

public function chargeCreditCard($amount, $creditCardDetails)
{
$transactionRequest = new AnetAPI\TransactionRequestType();
$transactionRequest->setTransactionType("authCaptureTransaction");
$transactionRequest->setAmount($amount);
$transactionRequest->setPayment($creditCardDetails);

$request = new AnetAPI\CreateTransactionRequest();
$request->setMerchantAuthentication($this->merchantAuthentication);
$request->setTransactionRequest($transactionRequest);

$controller = new CreateTransactionController($request);
$response = $controller->executeWithApiResponse(ANetEnvironment::SANDBOX);

return $response;
}
}

Test the transaction logic in a sandbox environment before moving to production. Ensure all payment information is handled securely to comply with PCI DSS standards.
