Question

我正在按如下方式拉取一个集合

$collection = Mage::getModel('catalog/product')->getCollection()
->addAttributeToSelect('jan')
->addAttributeToSelect('name')
->addAttributeToSelect('upc')
->addAttributeToSelect('ean')
->addAttributeToSelect('price')
->addAttributeToFilter('ean', array('neq' => ''))
->addFieldToFilter(array(
    array('attribute'=>'type_id','eq'=>'simple')        
))
->setPage(1,5);

目前我正在选择所有简单的产品，其中'ean'不为空。如何选择所有简单的产品，或者up或者jan不为空。

换句话说，只要产品有ean，upc或jan，就选择所有产品。如果它们都是空的，请不要选择它。

public function addAttributeToFilter($attribute, $condition = null, $joinType = 'inner')

溶液：

$collection->addAttributeToFilter(
array(
    array(
        'attribute' => 'ean',
        'neq'        => '',
        ),
    array(
        'attribute' => 'upc',
        'neq'      => '',
        ),
    ),
    array(
        'attribute' => 'jan',
        'neq'      => '',
        ),
    )
);

Magento集合过滤器，其中任何属性为空
