产品集合上的多项选项属性过滤器不起作用

Question

我试图基于一个属性过滤产品集合，该属性是多选择属性。这是我的代码，

$collection2 = Mage::getModel('catalog/product')->getCollection();

$collection2->addAttributeToSelect('name'); 
$collection2->addAttributeToSelect('manufacturer');
$collection2->addAttributeToSelect('printer_family');
$collection2->addAttributeToSelect($attributeCode);

$collection2->addFieldToFilter(array(
array('attribute'=>'manufacturer','eq'=>$ctname), 
)); 


$collection2->addFieldToFilter(array(
array('attribute'=>'printer_family','eq'=>$value), //this filter is not working
)); 

.

变量$值被检索如下

$product->getAttributeText($attributeCode);

.

谁能告诉我我做错了什么？

Answer 1

只是改变

->addFieldToFilter(array(
array('attribute'=>'printer_family','eq'=>$value), //this filter is not working
)); 

.

到

addFieldToFilter('printer_famil',
    array(
        array('finset'=> array($val1)),
        array('finset'=> array($val2)),
        array('finset'=> array($val3)),
    )
);

.
