我最近面临同样的问题。
我记录了我的调查here。
我没能找到框架API提供特定类别的过滤属性,但是我将分享解决方法。
基本上在Magento 2中的所有过滤属性可以从FilterableAttributeList被retrived:
$filterableAttributes = ObjectManager::getInstance()->get(\Magento\Catalog\Model\Layer\Category\FilterableAttributeList::class);
$attributes = $filterableAttributes->getList();
请使用DI代替的ObjectManager ::的getInstance()。我用它只是为了有更紧凑的例子:)
检索参与分层导航过滤器是比较麻烦一些。
$filterableAttributes = ObjectManager::getInstance()->get(\Magento\Catalog\Model\Layer\Category\FilterableAttributeList::class);
$appState = ObjectManager::getInstance()->get(\Magento\Framework\App\State::class);
$layerResolver = ObjectManager::getInstance()->get(\Magento\Catalog\Model\Layer\Resolver::class);
$filterList = ObjectManager::getInstance()->create(
\Magento\Catalog\Model\Layer\FilterList::class,
[
'filterableAttributes' => $filterableAttributes
]
);
$category = 1234;
$appState->setAreaCode('frontend');
$layer = $layerResolver->get();
$layer->setCurrentCategory($category);
$filters = $filterList->getFilters($layer);
但是,这不是最终结果。为了确保过滤器是实际的,需要检查每个过滤器的项目数量。
$finalFilters = [];
foreach ($filters as $filter) {
if ($filter->getItemsCount()) {
$finalFilters[] = $filter;
}
}
然后你就可以得到过滤器名和值(即检查核心分层导航rendering期间实际执行)。即:
$name = $filter->getName();
foreach ($filter->getItems() as $item) {
$value = $item->getValue();
}
最后,我想补充替代的解决方案,就是有点残酷,认为:)
$categoryId = 1234;
$resource = ObjectManager::getInstance()->get(\Magento\Framework\App\ResourceConnection::class);
$connection = $resource->getConnection();
$select = $connection->select()->from(['ea' => $connection->getTableName('eav_attribute')], 'ea.attribute_id')
->join(['eea' => $connection->getTableName('eav_entity_attribute')], 'ea.attribute_id = eea.attribute_id')
->join(['cea' => $connection->getTableName('catalog_eav_attribute')], 'ea.attribute_id = cea.attribute_id')
->join(['cpe' => $connection->getTableName('catalog_product_entity')], 'eea.attribute_set_id = cpe.attribute_set_id')
->join(['ccp' => $connection->getTableName('catalog_category_product')], 'cpe.entity_id = ccp.product_id')
->where('cea.is_filterable = ?', 1)
->where('ccp.category_id = ?', $categoryId)
->group('ea.attribute_id');
$attributeIds = $connection->fetchCol($select);
然后可以使用属性ID来加载集合。
/** @var $collection \Magento\Catalog\Model\ResourceModel\Product\Attribute\Collection */
$collection = $this->collectionFactory->create();
$collection->setItemObjectClass('Magento\Catalog\Model\ResourceModel\Eav\Attribute')
->addStoreLabel($this->storeManager->getStore()->getId());
$collection->addFieldToFilter('attribute_id', ['in' => $attributeIds]);
@Segey:它只返回属性代码。我需要它的所有可用标签值为 –
对于过滤器 - 使用$ filter-> getName(),$ filter-> getItems() - > getValue()。如果您引用最后一个解决方案 - 使用ids加载Magento \ Catalog \型号\ ResourceModel \产品\属性\收藏。我将添加一行来回答 –
好吧让我检查 –
