I would like to export Magento Sales Order Customer info programmatically, what functions or methods should I use and what steps should I do to export the Magento sales order customer info programmatically
You need to retrieve the Magento sales orders first (with attribute filter if need), then call fputcsv to save data into excel format file
Mage::app()->getStore()->setId(Mage_Core_Model_App::ADMIN_STORE_ID);
$orders = Mage::getModel('sales/order')->getCollection();
$orders->addAttributeToFilter('grand_total', array('gt' => '10.00'));
$fp = fopen('path/exportfile.csv', 'w');
if(count($orders) > 0){
foreach($orders as $order) {
$countryCode = $order->getBillingAddress()->getCountryId();
$country = Mage::getModel('directory/country')->loadByCode($countryCode);
$countryName = $country->getName();
$fields = array($order->getId(), $order->getBillingAddress()->getFirstname(),$order->getBillingAddress()->getLastname(), $order->getBillingAddress()->getEmail(), $order->getBillingAddress()->getCity(), $order->getBillingAddress()->getTelephone(), $countryName, $order->getStatus());
fputcsv($fp, $fields);
}
}
