Magento: Getting back shopping cart items after order fails

It’s very awkward if users place an order in your website and by chance the order fails, from end user side or some technical glitch, shopping cart becomes empty. User have to again add items in cart and go through the process which becomes tedious and may be changing their mind to shop.

So here’s a code that does the trick and preserves shopping cart content even if order gets failed.
Open your file where you’re handling your order failure action in frontend. (generally Mage/Checkout/controllers/OnepageController.php)

public function failureAction()
{
    $lastQuoteId = $this->getOnepage()->getCheckout()->getLastQuoteId();
    $lastOrderId = $this->getOnepage()->getCheckout()->getLastOrderId();


    if ($lastQuoteId && $lastOrderId) {
        $orderModel = Mage::getModel('sales/order')->load($lastOrderId);
        if($orderModel->canCancel()) {
            
            $quote = Mage::getModel('sales/quote')->load($lastQuoteId);
            $quote->setIsActive(true)->save();
            
            $orderModel->cancel();
            $orderModel->setStatus('canceled');
            $orderModel->save();

            Mage::getSingleton('core/session')->setFailureMsg('order_failed');
            Mage::getSingleton('checkout/session')->setFirstTimeChk('0');
            $this->_redirect('kcheckout/index/payment', array("_forced_secure" => true));
            return;
        }
    }
    if (!$lastQuoteId || !$lastOrderId) {
        $this->_redirect('checkout/cart', array("_forced_secure" => true));
        return;
    }

    $this->loadLayout();
    $this->renderLayout();
}

Be noted here that we don’t have here onepage checkout so we’re redirecting user to payment page after restoring the cart. You can redirect user to any page as per your need after the cart is restored and previous order is cancelled.

Magento: Joining/group by – order, invoice, shipment tables

Ever tried to join multiple tables in Magento? Joining and grouping tables is not that easy in Magento ORM than in simple MySql way we did for years.

Here is a piece of code where I was required to grab all the data from orders, invoices, shipments to generate reports for warehouse people to make their life easier.

$collection = Mage::getResourceModel('sales/order_shipment_item_collection');
$collection->addFieldToSelect('section_id');
$collection->addFieldToSelect('shelf_id');
$collection->addFieldToSelect('rack_id');
$collection->addFieldToSelect('box_id');
//$collection->addFieldToSelect('GROUP_CONCAT(DISTINCT main_table.product_id SEPARATOR ",")','product_ids');</p>
$collection->getSelect()->joinLeft('sales_flat_shipment_grid', 'main_table.parent_id = sales_flat_shipment_grid.entity_id', array('increment_id as shipment_increment_id', 'created_at as shipment_created_at', 'order_increment_id','total_qty'));
$collection->getSelect()->joinLeft('sales_flat_shipment_track', 'sales_flat_shipment_grid.entity_id = sales_flat_shipment_track.parent_id', array('number as track_id', 'carrier_code as carrier_name'));
$collection->getSelect()->joinLeft('sales_flat_order', 'sales_flat_shipment_track.order_id = sales_flat_order.entity_id', array('created_at as order_created_at','grand_total as ord_grand_total'));
$collection->getSelect()->joinLeft('sales_flat_order_item', 'main_table.order_item_id = sales_flat_order_item.item_id', array('product_type'));
$collection->getSelect()->joinLeft('sales_flat_order_payment', 'sales_flat_shipment_track.order_id = sales_flat_order_payment.parent_id', array('method as payment_method'));
$collection->getSelect()->joinLeft('sales_flat_order_address', 'sales_flat_shipment_track.order_id = sales_flat_order_address.parent_id', array('firstname','lastname','street','city','postcode','region','telephone'));
$collection->getSelect()->joinLeft('sales_flat_invoice', 'sales_flat_shipment_track.order_id = sales_flat_invoice.order_id', array('grand_total'));
//$collection->addAttributeToFilter('main_table.price', array('gt' => 0));
if($pickup_ids!='' &#038;&#038; is_array($pickup_ids))
    $collection->addAttributeToFilter('sales_flat_shipment_grid.entity_id', array('in' => $pickup_ids));
$collection->getSelect()->columns(
    array('product_ids' => new Zend_Db_Expr(
        "IFNULL(GROUP_CONCAT(DISTINCT main_table.product_id SEPARATOR ';'), '')"
)));
$collection->getSelect()->columns(
    array('weight' => new Zend_Db_Expr(
        "IFNULL(SUM(main_table.weight)/2, '')"
)));
$collection->getSelect()->group('shipment_increment_id');
//$collection->getSelect()->group('track_id');
//Mage::log($collection->getSelect()->__toString());
$this->setCollection($collection);
//$this->getCollection()->getSelect()->limit();

Although the query is so expensive, I have not yet tried to optimize it due to lack of time.

Magento: Getting more than one records from core_config_data table

To select any particular record from core_config_data table in magento is quite simple.

1

Mage::getStoreConfig('sales_email/order/template');

But what if you want all the data pertaining to sales order email or for any other thing stored in magento’s config table? You may need other data like “enabled”, “identity”, “guest_template”, “copy_to” which can accomplish otherwise in 5 requests.
So here is how you should write the code to get all the data for some particular expression as per your need.

1
2

$qrySalesOrder = Mage::getModel('core/config_data')->getCollection()->addFieldToFilter('path',array('like'=>'sales_email/order/%'));
//Mage::log($qrySalesOrder);

Magento Admin – Forcing Invoice and Ship button together

Ever wondered what if you want to do invoice and shipment with just one click in your website admin? Yes, Magento allows you to integrate both these in one step.

Edit your module’s config.xml and Observer.php for this to happen.

config.xml snippet:

1

3
4
5
6
7
8
9
10
11

<events>
            <sales_order_place_after>
                <observers>
                    <namespace_module>
                        <type>singleton</type>
                        <class>Namespace_Module_Model_Observer</class>
                        <method>doForceInvoiceWithShipment</method>
                    </namespace_module>
                </observers>
            </sales_order_place_after>
</events>

Every time a order is placed, frontend as well as backend, your observer method will be called which will force invoice and shipment to show in one button in Manage Orders for particular order at backend.

Observer.php snippet:

1
2
3
4
5

public function doForceInvoiceWithShipment($observer) {
        $order = $observer->getOrder();
        $orderId = $order->getIncrementId();
        Mage::getModel('sales/order')->loadByIncrementId($orderId)->setForcedDoShipmentWithInvoice(true)->save();
}

Now you can place a order and check at backend under Sales->Orders clicking on latest order to see “Invoice & Ship” button integrated rather than “Invoice” and “Ship” button separated.

} else {
    $tax = '';
}
