Magento – How to check if a collection has items

user1618341,According magento an order can place from one store,Magento is save order store id at sales_flat_order,sales_flat_grid order.

At your collection you need get store_id.Also need rectify collection query,Please use * instead of some field

<?php
    try {
        $orders = Mage::getModel('sales/order')->getCollection()
            ->addFieldToFilter(
                'status',
                array(
                    'nin' => array('complete', 'canceled', 'processing', 'holded', 'fraud'),
                    'in' => 'pending',
                ))
            ->addAttributeToSelect('store_id')
            ->addAttributeToSelect('status');
    }
catch (Mage_Core_Exception $e) {
}

I have put the condition to skip create shipment for one store view[if($eachorder->getData('store_id')!=='YOUSKIPSTOREID'):]

see code:

try {

    foreach ($orders as $eachorder) {


        $order = Mage::getModel("sales/order")->load($eachorder->getId());
        if (!$order->canInvoice()) {
            Mage::throwException(Mage::helper('core')->__('Cannot create an invoice.'));
        }
        $invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();
        if (!$invoice->getTotalQty()) {
            Mage::throwException(Mage::helper('core')->__('Cannot create an invoice without products.'));
        }
        $invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_ONLINE);
        $invoice->register();
        $transactionSave = Mage::getModel('core/resource_transaction')
            ->addObject($invoice)
            ->addObject($invoice->getOrder());
        $transactionSave->save();
        /* put code for skip for one store */
        if($eachorder->getData('store_id')!=='YOUSKIPSTOREID'):

            $shipment = $order->prepareShipment();

            if ($shipment) {
                $shipment->register();
                $order->setIsInProcess(true);

                $transaction_save = Mage::getModel('core/resource_transaction')
                    ->addObject($shipment)
                    ->addObject($shipment->getOrder())
                    ->save();
            } else {
                throw new Exception("Cant get shipment");
            }
        endif;

        $order->setState(Mage_Sales_Model_Order::STATE_COMPLETE);
        $order->save();
    }

}catch (Mage_Core_Exception $e) {

}

If you getting the issues for create invoice and shipment,Please see my Blog:

Create invoice:

Create Shipment:

The table you are looking for is a simple table.

When your host restored your database, it sounds like it did not have the core_store table inside of it. Also, it might be that there is a table prefix that might or might not be at play here.

Try these first:

1. Check your database to ensure there is a core_store (or variant) table available.
2. Check to make sure your local.xml config file is pointing to the right database.
3. Ask your host to restore from another restore point.
4. Check to ensure your local.xml didn't have a table prefix recently added or removed.

If that does not work, you can always do raw SQL inside your database.

PLEASE NOTE: TEST THIS ON A NON PRODUCTION ENVIRONMENT BEFORE PRODUCTION!

Core Store Table:

CREATE TABLE `core_store` (
  `store_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Store Id',
  `code` varchar(32) DEFAULT NULL COMMENT 'Code',
  `website_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Website Id',
  `group_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Group Id',
  `name` varchar(255) NOT NULL COMMENT 'Store Name',
  `sort_order` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Store Sort Order',
  `is_active` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Store Activity',
  PRIMARY KEY (`store_id`),
  UNIQUE KEY `UNQ_core_store_CODE` (`code`),
  KEY `IDX_core_store_WEBSITE_ID` (`website_id`),
  KEY `IDX_core_store_IS_ACTIVE_SORT_ORDER` (`is_active`,`sort_order`),
  KEY `IDX_core_store_GROUP_ID` (`group_id`),
  CONSTRAINT `FK_core_store_GROUP_ID_core_store_GROUP_GROUP_ID` FOREIGN KEY (`group_id`) REFERENCES `core_store_group` (`group_id`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `FK_core_store_WEBSITE_ID_WBCORE_WEBSITE_WEBSITE_ID` FOREIGN KEY (`website_id`) REFERENCES `wbcore_website` (`website_id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COMMENT='Stores';

Insert default entries:

INSERT INTO `core_store` VALUES (0,'admin',0,0,'Admin',0,1),(1,'default',1,1,'Default Store View',0,1);
