OR and语句addAttributeToFilter magento

我创建了以下代码

$todayDate  = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT);
$tomorrow = mktime(0, 0, 0, date('m'), date('d')+1, date('y'));
$dateTomorrow = date('m/d/y', $tomorrow);

$collection = Mage::getResourceModel('catalog/product_collection');
$collection->setVisibility(Mage::getSingleton('catalog/product_visibility')->getVisibleInCatalogIds());

$collection = $this->_addProductAttributesAndPrices($collection)
->addStoreFilter()
->addAttributeToFilter('special_price', array('neq' => ""))
->addAttributeToFilter('special_from_date', array('date' => true, 'to' => $todayDate))
->addAttributeToFilter('special_to_date', array('or'=> array(0 => array('date' => true, 'from' => $dateTomorrow), 1 => array('is' => new Zend_Db_Expr('null')))), 'left');

这很好用。但我现在想用OR语句。 我想我可以用这个来解决它：

$collection->addAttributeToFilter(array(
array('attribute'=> 'someattribute','like' => 'value'),
array('attribute'=> 'otherattribute','like' => 'value'),
array('attribute'=> 'anotherattribute','like' => 'value'),
));

但没有成功。 所以我的问题是如何添加或声明

$todayDate  = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT);
$tomorrow = mktime(0, 0, 0, date('m'), date('d')+1, date('y'));
$dateTomorrow = date('m/d/y', $tomorrow);

$collection = Mage::getResourceModel('catalog/product_collection');
$collection->setVisibility(Mage::getSingleton('catalog/product_visibility')->getVisibleInCatalogIds());

$collection = $this->_addProductAttributesAndPrices($collection)
->addStoreFilter()
->addAttributeToFilter('special_price', array('neq' => ""))
->addAttributeToFilter('special_from_date', array('date' => true, 'to' => $todayDate))
->addAttributeToFilter('special_to_date', array('or'=> array(0 => array('date' => true, 'from' => $dateTomorrow), 1 => array('is' => new Zend_Db_Expr('null')))), 'left');

或

多谢各位

太好了,， Lex检查以下链接

检查以下链接

来自Magento维基：

// Add OR condition:
$collection->addAttributeToFilter(array(
    array(
        'attribute' => 'field_name',
        'in'        => array(1, 2, 3),
        ),
    array(
        'attribute' => 'date_field',
        'from'      => '2000-09-10',
        ),
    ));

所以写下你的查询，据我所知，是

"....WHERE special_price <> "" AND special_from_date <= '2012-07-02' AND (special_to_date >= '2012-07-03' OR special_to_date IS NULL)..."
