Magento中分层导航的分类

Question

我正在寻求增强Magento中的分层导航.

目前,分层导航中使用的属性无法分组,这意味着如果您有多个逻辑上属于一个组的属性(即属性"高度","宽度"和"深度",即"尺寸"和"颜色" "和"纹理"属于"外观"部分).

我认为这会增强用户的可用性和导航.

在我开始为此开发一个模块之前,我想知道是否有人为magento遇到这样的事情,如果没有,你有任何提示应该怎么做？

我为此创建了一个模块.以下是我所做的更改:

MYNAME /导航/目录/型号/ Layer.php:

class MyName_Navigation_Catalog_Model_Layer extends Mage_Catalog_Model_Layer {
    public function getFilterableAttributes()
    {
        $setIds = $this->_getSetIds();
        if (!$setIds) {
            return array();
        }

        $collection = Mage::getResourceModel('catalog/product_attribute_collection')
            ->setItemObjectClass('catalog/resource_eav_attribute');

        $collection->addSetInfo(true);

        $collection->getSelect()->distinct(true);
        $collection
            ->setAttributeSetFilter($setIds)
            ->addStoreLabel(Mage::app()->getStore()->getId())
            ->setOrder('position', 'ASC');

        $collection = $this->_prepareAttributeCollection($collection);
        $collection->load();

        return $collection;
    }
}

我只是用Mage_Catalog_Model_Layer重写了被覆盖的函数:

        $collection->addSetInfo(true);

这可确保在需要时加载组数据.

接下来的两个更改只允许您访问数据.

MYNAME /导航/目录/型号/层/ Attribute.php:

class MyName_Navigation_Catalog_Model_Layer_Filter_Attribute extends Mage_Catalog_Model_Layer_Filter_Attribute {

    public function getGroupName($setId = 4) {       
        $attribute = $this->getAttributeModel();
        $group_id = $attribute->getData('attribute_set_info/' . $setId . '/group_id');
        $group = Mage::getModel('eav/entity_attribute_group')->load($group_id);
        $group_name = $group->getData('attribute_group_name');

        return $group_name;
    }

}

MYNAME /导航/目录/型号/层/ Item.php:

class MyName_Navigation_Catalog_Model_Layer_Filter_Item extends Mage_Catalog_Model_Layer_Filter_Item {
    public function getGroupName()
    {
        return $this->getFilter()->getGroupName();
    }
}

MYNAME /导航/目录/块/层/过滤/ Attribute.php:

class MyName_Navigation_Catalog_Block_Layer_Filter_Attribute extends Mage_Catalog_Block_Layer_Filter_Attribute {
    public function getGroupName() {
        return $this->_filter->getGroupName();
    }
}

告诉magento使用我的模块而不是核心文件.MYNAME /导航的/ etc/config.xml中

<?xml version="1.0" encoding="UTF-8"?>

<config>
    <modules>
        <MyName_Navigation>
            <version>0.1.0</version>
        </MyName_Navigation>
    </modules>
    <global>
        <blocks>
            <catalog>
                <rewrite>
                    <layer_filter_attribute>MyName_Navigation_Catalog_Block_Layer_Filter_Attribute</layer_filter_attribute>
                </rewrite>
            </catalog>
        </blocks>
        <models>
            <catalog>
                <rewrite>
                    <layer>MyName_Navigation_Catalog_Model_Layer</layer>
                    <layer_filter_attribute>MyName_Navigation_Catalog_Model_Layer_Filter_Attribute</layer_filter_attribute>
                    <layer_filter_item>MyName_Navigation_Catalog_Model_Layer_Filter_Item</layer_filter_item>
                </rewrite>
            </catalog>
        </models>
    </global>
</config>

现在你可以打电话了

$_item->getGroupName();

来自您的模板文件:template/catalog/layer/filter.php或

$ _filter-> getGroupName(); 从您的模板文件:template/catalog/layer/view.php和Group/Sort属性.
