Automatic onepage checkout - quote issue - php

Question

I'm creating automated checkout feature, which will create few orders at once:
What's wrong with that?
This script let's say creates 4 different orders with different prodcuts, for different users, but problem lies here, each order created after first order has got subtotal and grand total of first order. How can I reset that?
Mage::app('default');
/**
* Get the resource model
*/
$resource = Mage::getSingleton('core/resource');
/**
* Retrieve the read connection
*/
$readConnection = $resource->getConnection('core_read');
$query = 'SELECT * FROM m4gsrepeated_orders WHERE execution <= CURDATE()';
$all_orders = $readConnection->fetchAll($query);
function addCartItems($products_array) {
$cart = Mage::getModel('checkout/cart');
foreach($products_array as $productw) {
$sku = $productw[0];
/** #var $productCollection Mage_Catalog_Model_Resource_Product_Collection */
$productCollection = Mage::getModel( 'catalog/product' )
->getResourceCollection()
->addFieldToFilter( 'sku', $sku );
/** #var $product Mage_Catalog_Model_Product */
$product = $productCollection->getFirstItem();
// you should have the product now, maybe it isn't even necessary to get the ID
$product = $product->load($product->getId());
$cart->addProduct($product, $productw[1]);
}
$cart->save();
}
foreach ($all_orders as $order) {
//Set basic data
Mage::getSingleton('checkout/session')->getQuote()->setReservedOrderId(null);
$customer = Mage::getModel('customer/customer')
->setWebsiteId(Mage::app()->getStore()->getWebsiteId())
->load($order['user_id']);
// Set as Logged In and Clear Session
Mage::getSingleton('customer/session')->setCustomerAsLoggedIn($customer)->renewSession();
//Set up cart
$cart = Mage::getModel('checkout/cart')->getQuote();
//get current cart items;s
$i=1;
foreach ($cart->getAllItems() as $item) {
$products_current[$i][0] = $item->getProduct()->getSku();
$products_current[$i][1] = intval($item->getQty());
$i++;
}
$i=1;
$cart = Mage::getModel('checkout/cart');

//addCartItems($products_delayed);
$cart->truncate();

}

Answer 1

Problem is fixed:
That lied in checkout/session and customer/session which had to be cleared.
Mage::getSingleton('checkout/session')->clear();
Mage::getSingleton('customer/session')->clear();
That might help someone when resolving batch ordering solution with similar method.
Thanks,
