如何以编程方式在Magento中获取可汇总的属性和选项

Question

我想要类别的可过滤属性及其选项，因此我使用以下代码

$layer = Mage::getModel("catalog/layer");
$category = Mage::getModel("catalog/category")->load($category_id);
$layer->setCurrentCategory($category);
$attributes = $layer->getFilterableAttributes();
foreach($attributes as $attribute){
    if($attribute->getAttributeCode() == 'price'){
        $filterBlockName = 'catalog/layer_filter_price';
    }elseif($attribute->getBackendType() == 'decimal'){
        $filterBlockName = 'catalog/layer_filter_decimal';
    }else{
        $filterBlockName = 'catalog/layer_filter_attribute';
    }

    $result = Mage::app()->getLayout()->createBlock($filterBlockName)->setLayer($layer)->setAttributeModel($attribute)->init();
    $count = count($result->getItems());
    if($count > 0){
        $attribute->getFrontendLabel();
        $attribute->getAttributeCode();
    }
    if($count > 0){
        foreach($result->getItems() as $option) {
            $option->getLabel();
            $option->getValue();
        }
    }
}

.

现在我得到了正确的输出。例如，我正在进行输出

brand - HP,Dell
processer - i3,i5,i7

. 现在问题是当我应用一个名为处理器i7的过滤器时，我只有一个名为Dell的产品，所以一个戴尔产品被正确显示，但我需要默认属性如下

brand - Dell
processer - i3,i5,i7

.

我得到的是惠普和戴尔。这是编程方式我正在做。我需要层叠导航在Magento类别清单页面中的方式。

我用以下代码做了自己，只是分享对这里的其他人有所帮助的代码

$categoryId = '5'; // replace with your category id here
$category = Mage::getModel("catalog/category")->load($categoryId);
$layer = Mage::getModel("catalog/layer");
$layer->setCurrentCategory($category);

$setIds = Mage::getModel('eav/entity_attribute_set')
            ->load($attrSetName, 'attribute_set_name')
            ->getAttributeSetId();

$attributes = Mage::getResourceModel('catalog/product_attribute_collection');
$attributes->setItemObjectClass('catalog/resource_eav_attribute')
                ->setAttributeSetFilter($setIds)
                ->addStoreLabel(Mage::app()->getStore()->getId())
                ->setOrder('position', 'ASC');


$attributes->addFieldToFilter('additional_table.is_filterable', array('gt' => 0));
$attributes->load();

foreach ($attributes as $attribute) {
    $filter_attr = array();
    $filter_attr['title'] = $attribute->getFrontendLabel();
    $filter_attr['code'] = $attribute->getAttributeCode();

    if ($attribute->getAttributeCode() == 'price') {
        $filterBlockName = 'catalog/layer_filter_price';
    }elseif ($attribute->getBackendType() == 'decimal') {
        $filterBlockName = 'catalog/layer_filter_decimal';
    }else {
        $filterBlockName = 'catalog/layer_filter_attribute';
    }

    $result =  Mage::app()->getLayout()->createBlock($filterBlockName)->setLayer($layer)->setAttributeModel($attribute)->init();
    $i=0;

    foreach($result->getItems() as $option) {
        $attr_option = array();
        if($attribute->getAttributeCode() == 'price') {
            $attr_option['label'] = str_replace(array('<span class="price">','</span>'),'',$option->getLabel());
        } else {
            $attr_option['label'] = $option->getLabel();
        }

        $attr_option['value'] = $option->getValue();
        $attr_option['count'] = $option->getCount();
        $i++;
        $filter_attr['options'][] = $attr_option;
    }

    if($i!=0){
        $filter_attributes[] = $filter_attr;
    }
}
