Zend Framework and Authorize.net integration

Question

Has anyone ever built anything on the subject? Authorize.Net is one of the most widely used payment gateways so i'd image there would be a best practice and/or a solid resource for this integration. I wasn't able to find anything as reliable from my search. Any advise/resource/suggestion is greatly appreciated. "sharing is caring"

Answer 1

The APIs for Paypal and Authorize.net are pretty straightforward. You wouldn't really need to use Zend specific methods to set them up within a Zend application. Magento, which is built on Zend, has an Authorize.net connection, you could take a look at that. Opencart is another open-source shopping cart that has an Authorize.net plugin. I have looked at that and it is decently written and easy to understand.

EDIT: Here's the class for Authorize.net AIM from Opencart (They have a SIM version as well). You should be able to make your own using this as a basis fairly easily.

class ControllerPaymentAuthorizeNetAim extends Controller {
    protected function index() {
        $this->language->load('payment/authorizenet_aim');

        $this->data['text_credit_card'] = $this->language->get('text_credit_card');

        $this->data['entry_cc_expire_date'] = $this->language->get('entry_cc_expire_date');
        $this->data['entry_cc_cvv2'] = $this->language->get('entry_cc_cvv2');

        $this->data['button_confirm'] = $this->language->get('button_confirm');

        $this->data['months'] = array();

        for ($i = 1; $i <= 12; $i++) {
            $this->data['months'][] = array(
                'text'  => strftime('%B', mktime(0, 0, 0, $i, 1, 2000)), 
                'value' => sprintf('%02d', $i)
            );
        }

        $today = getdate();

        $this->data['year_expire'] = array();

        for ($i = $today['year']; $i < $today['year'] + 11; $i++) {
            $this->data['year_expire'][] = array(
                'text'  => strftime('%Y', mktime(0, 0, 0, 1, 1, $i)),
                'value' => strftime('%Y', mktime(0, 0, 0, 1, 1, $i))
