每个属性'country_of_manufacture'的magento产品计数

Question

我需要根据属性'country_of_manufacture'计算/分组/选择产品。 像这样

  

India =＆gt; 10，Shrilanka =＆gt; 5，

如何在magento中实现它？

Answer 1

    $collection = $this->getLoadedProductCollection()
        ->addAttributeToSelect('*')
        ->addExpressionAttributeToSelect('total_country_of_manufacture',"COUNT({{entity_id}})",'entity_id')
        ->groupByAttribute('country_of_manufacture');

为计数

Mage::getModel('catalog/product')->getCollection()->groupByAttribute('country_of_manufacture')
                ->addExpressionAttributeToSelect("cnt_product",'COUNT({{entity_id}})', 'entity_id')
                ->load();

Answer 2

而不是使用

count($collection)

你可以尝试

$collection->getSelect()->count();
