Magento的產品收集與特定ID

Question

我選擇產品

$products = Mage::getModel('catalog/product')->getCollection()->addAttributeToFilter('entity_id', array('in' => $productIds)); 

我怎麼能archieve該集合是相同的順序在$ productIds的ID？

感謝

Answer 1

$productIds = array(1,3,2); 
    $products = Mage::getModel('catalog/product')->getCollection() 
       ->addAttributeToFilter('entity_id', array('in' => $productIds)); 


    $products->getSelect()->order("find_in_set(entity_id,'".implode(',',$productIds)."')"); 

    foreach($products as $product) 
    { 
     echo $product->getEntityId(); 
     echo $product->getSku(); 
    }
