Basic Usage

There is going to be a lot of different things you can do with the Google Checkout API -- so really I've just got things started. You can extend as you see fit.

Usage to Create a Cart/Checkout Order

In any controller, you can setup a method like this to facilitate the Google Cart Checkout functionality

<?php /* in a controller */
/**
* prep the google checkout data
*/
private function __googleCart($order=null) {
if (empty($order)) {
	return false;
}
$this->GoogleCheckoutCart->setup();

// set custom tracking data, for this order
$this->GoogleCheckoutCart->cart->SetMerchantPrivateData(new MerchantPrivateData(array(
	"order_id" => $order['Order']['id'],
	"created" => $order['Order']['created'],
	"user_id" => $order['Order']['user_id'],
	"design_id" => $order['Order']['design_id'],
	"submitted_from" => Router::url($this->here, true),
	"admin_url" => Router::url("/admin/orders/view/{$order['Order']['id']}", true),
	"mod_url" => Router::url("/mod/orders/view/{$order['Order']['id']}", true),
	)));


// put in items (assumes you already have them in your $order data)
foreach ( $order['OrderItem'] as $orderItem ) {
	$this->GoogleCheckoutCart->item(array(
		'name' => $orderItem['name'],
		'description' => OrderItem::desc($orderItem),
		'quantity' => max($orderItem['qty'], 1),
		'unit_price' => $orderItem['cost'],
		'numeric_weight' => max($orderItem['qty'], 1),
		'item_weight' => 'LB',
		'sku' => $orderItem['sku'],
		));
}

// setup shipping
if (count($order['OrderItem']) < 3) {
	   $shipping = new GoogleFlatRateShipping("USPS Priority Mail", 4.55);
} else {
	   $shipping = new GoogleFlatRateShipping("USPS Priority Mail", 6.2);
}
$Gfilter = new GoogleShippingFilters();
$Gfilter->SetAllowedCountryArea('CONTINENTAL_48');
$shipping->AddShippingRestrictions($Gfilter);
$this->GoogleCheckoutCart->cart->AddShipping($shipping);

// setup taxes
$this->GoogleCheckoutCart->tax();

//debug($this->GoogleCheckoutCart->cart->GetXML());

// finalize
if ($this->request->is('post')) {
	// checkout hit, send XML data via API and redirect
	$this->GoogleCheckoutCart->cart->SetAnalyticsData($_POST['analyticsdata']);
	$order['Order']['status'] = 'checkout';
	$this->Order->save($order);
	$this->GoogleCheckoutCart->cart->CheckoutServer2Server();
	// should redirect on it's own... unless there's an error
} else {
	// will setup a button/JS/form to submit back to self, and redirect away to Google Checkout
	$checkout_button = $this->GoogleCheckoutCart->cart->CheckoutServer2ServerButton($this->here, 'large', true);
	$this->set(compact('checkout_button'));
}
}
?>
