Magento BestSeller Module - Summing Configurable Products And Adding Them Back In

Question

This has been bugging me for quite a while. Basically, what we are trying to achieve is in the bestsellers on our front page, to have the products listed in the amount sold. For

Answer 1

You can use the following piece of code to get the simple products attached to the configurable product. I'm not sure if this is 100% correct, I haven't tried it myself.

$simpleProducts = Mage::getModel('catalog/product_type_configurable')->getUsedProducts(null, $product);

Answer 2

Thanks for posting that sample code! I was able to use it to create a solution which should work well for both of us.

I found that configurable product sales are being summed correctly but aren't being included in the results; their child products appear instead. My solution was to include configurable products, do a left join on the catalog_product_super_link table, and filter out anything that has a parent_id. Here are the changes you'll need to make:

Collection.php:

    public function addOrderedQty($from = '', $to = '', $getComplexProducts=false, $getComplexChildProducts = true, $getRemovedProducts = true)
    {
        $qtyOrderedTableName = $this->getTable('sales/order_item');
        $qtyOrderedFieldName = 'qty_ordered';

        $productIdFieldName = 'product_id';

        if (!$getComplexProducts) {
            $compositeTypeIds = Mage::getSingleton('catalog/product_type')->getCompositeTypes();
            $productTypes = $this->getConnection()->quoteInto(' AND (e.type_id NOT IN (?))', $compositeTypeIds);
        } else {
            $productTypes = '';
        }

        if ($from != '' && $to != '') {
            $dateFilter = " AND `order`.created_at BETWEEN '{$from}' AND '{$to}'";
        } else {
            $dateFilter = "";
        }

        $this->getSelect()->reset()->from(
            array('order_items' => $qtyOrderedTableName),
            array(
                'ordered_qty' => "SUM(order_items.{$qtyOrderedFieldName})",
                'order_items_name' => 'order_items.name'
            )
        );

         $_joinCondition = $this->getConnection()->quoteInto(
                'order.entity_id = order_items.order_id AND order.state<>?', Mage_Sales_Model_Order::STATE_CANCELED
         );
         $_joinCondition .= $dateFilter;
         $this->getSelect()->joinInner(
            array('order' => $this->getTable('sales/order')),
            $_joinCondition,
            array()
         );

         // Add join to get the parent id for configurables
         $this->getSelect()->joinLeft(
             array('cpsl' => $this->getTable('catalog/product_super_link')),
             'cpsl.product_id = order_items.product_id',
             'cpsl.parent_id'
         );

        if(!$getComplexChildProducts)
            $this->getSelect()->having('parent_id IS NULL');

        if($getRemovedProducts)
        {
             $this->getSelect()
                ->joinLeft(array('e' => $this->getProductEntityTableName()),
                    "e.entity_id = order_items.{$productIdFieldName} AND e.entity_type_id = {$this->getProductEntityTypeId()}{$productTypes}")
                ->group('order_items.product_id');
        }
        else
        {
            $this->getSelect()
                ->joinInner(array('e' => $this->getProductEntityTableName()),
                    "e.entity_id = order_items.{$productIdFieldName} AND e.entity_type_id = {$this->getProductEntityTypeId()}{$productTypes}")
                ->group('e.entity_id');
        }


        $this->getSelect()->having('ordered_qty > 0');

        // This line is for debug purposes, in case you'd like to see what the SQL looks like
        // $x = $this->getSelect()->__toString();

        return $this;
    }

List.php - Find the following two lines...

$bestsellers->addOrderedQty($startDate, $todayDate, true);
$bestsellers->addOrderedQty('', '', true);

... and change them to:

$bestsellers->addOrderedQty($startDate, $todayDate, true, false, false);
$bestsellers->addOrderedQty('', '', true, false, false);

My changes added two new optional parameters, which both default to true, as to not break existing functionality.

• When $getComplexChildProducts is set to false, all child items of the configurable product will be removed from the results.
• $getRemovedProducts determines whether or not previously ordered products (which have since been deleted from Magento) should also appear.

Please note that your report statistics will need to be up-to-date in order to get accurate results.

Hope this helps! Let me know if you have any questions.
