Events Reference

This plugin raises two events, much like normal the Commerce add to cart, which you can listen for in the same way. They are:

onBeforeMultiAddToCart and onMultiAddToCart

In each case the event parameters are:

order (CommerceOrderModel) lineItems (an array of CommerceLineItemModel)

craft()->on('multiAdd_cart.onBeforeMultiAddToCart', function($event) {
    $order = $event->params['order'];
    $lineItems = $event->params['lineItems'];
    $event->performAction = false;
