我试图在下拉导航中获得产品属性'brand'。我可以得到的属性出现以下代码，但问题是品牌属性是不相关的某些类别出现在类别下拉。所以我需要的是品牌属性只出现在一个类别中，当有产品在该类别与品牌属性。如。品牌"精工"将出现在手表类别下拉，而不是项链类别下拉。任何帮助将非常感激!

我为感兴趣的人弄明白了…我没有针对产品集合验证属性选项，下面是更正后的代码。
<?php foreach($validAttributes as $validAttribute) : ?>
<?php
if ($validAttribute->getAttributeCode() == 'brand') {
$options = $validAttribute->getSource()->getAllOptions();
foreach ($options as $option) {
//Validate the product collection against each attribute option
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addCategoryFilter($_categoryModel);
$collection->addAttributeToFilter('brand',$option);
//if the count is greater than 0 after the collection has been filtered by category and product attribute option, echo the attribute.
if (count($collection) > 0) {
$optionNodeId = 'attribute-'.$id.'-'.$validAttribute->getId().'-'.$option['value'];
$data = array(
'name' => $option['label'],
'id' => $optionNodeId,
'url' => $catUrl.'?'.$validAttribute->getAttributeCode().'='.$option['value']
);
echo '<li><a href="'.$data['url'].'">'.$data['name'].'</a></li>';
}
}
}
?>
<?php endforeach; ?>
