具有特定 ID 的 magento 产品集合

Question

我选择的产品

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

我如何才能存档该集合与 $productIds 中的 ID 的顺序相同？

谢谢

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();
    }
