I need to create a new view template file for products filtered by a custom attribute set as "purpose".
So far so good, I have a template file that list products by visibility:
<?php
$visibility = array(
Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH,
Mage_Catalog_Model_Product_Visibility::VISIBILITY_IN_CATALOG
);
$storeId = Mage::app()->getStore()->getId();
$_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('*')
->addOrderedQty()
->addAttributeToFilter('visibility', $visibility)
->setOrder('ordered_qty', 'desc');
?>
How to make this code query for 'purpose'?
