Magento - 如何将分层导航添加到高级搜索？

Question

如何将"分层导航"添加到"高级搜索"结果页面？

Magento版本1.7.

Answer 1

下面的补丁将在高级搜索结果中显示分层导航,并且可以通过分层导航正常工作.分层导航和搜索结果基于两个单独的产品集合显示,一个由catalogsearch/Model/Layer.php创建,另一个由catalogsearch/Model/Advanced.php创建.因此,我们需要覆盖这两个模型的几个函数,以使分层导航工作在高级搜索中.

1-在catalogsearch_advanced_result标记下的local.xml中添加.

 <reference name="left">
      <block type="catalogsearch/layer" name="catalogsearch.leftnav" after="currency" template="catalog/layer/view.phtml"/>
 </reference>

覆盖prepareProductCollection catalogsearch /模型/ Layer.php的功能与

public function prepareProductCollection($collection){

    if(Mage::helper('catalogsearch')->getQuery()->getQueryText())//for normal search we get the value from query string q=searchtext
        return parent::prepareProductCollection($collection);
    else{

        $collection->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes());
        /**
         * make sure you cross check the $_REQUEST with $attributes
         */
        $attributes = Mage::getSingleton('catalog/product')->getAttributes();

        Mage::log(print_r($_REQUEST,1));
        foreach($attributes as $attribute){
            $attribute_code = $attribute->getAttributeCode();
            //Mage::log("--->>". $attribute_code);
            if($attribute_code == "price")//since i am not using price attribute
                continue;

            if (empty($_REQUEST[$attribute_code])){
                //Mage::log("nothing found--> $attribute_code");
                continue;
            }
            if(!empty($_REQUEST[$attribute_code]) && is_array($_REQUEST[$attribute_code]))
                $collection->addAttributeToFilter($attribute_code, array('in' => $_REQUEST[$attribute_code]));
            else
            if(!empty($_REQUEST[$attribute_code]))
                $collection->addAttributeToFilter($attribute_code, array('like' => "%" . $_REQUEST[$attribute_code] . "%"));
        }

        $collection->setStore(Mage::app()->getStore())
        ->addMinimalPrice()
        ->addFinalPrice()
        ->addTaxPercents()
        ->addStoreFilter()
        ->addUrlRewrite();

        //Mage::log($collection->getSelect()->__toString());

        Mage::getSingleton('catalogsearch/advanced')->prepareProductCollection($collection);    
        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);
    }

    return $this;
}

覆盖getProductCollection,catalogsearch /模型/ Advanced.php的getSearchCriterias功能与

public function getProductCollection(){

    if (is_null($this->_productCollection)) {
        $this->_productCollection = Mage::getResourceModel('catalogsearch/advanced_collection')
            ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
            ->addMinimalPrice()
            ->addStoreFilter();
            Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($this->_productCollection);
            Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($this->_productCollection);

        if(isset($_GET['cat']) && is_numeric($_GET['cat'])) 
            $this->_productCollection->addCategoryFilter(Mage::getModel('catalog/category')->load($_GET['cat']),true);
    }
    return $this->_productCollection;
}

public function getSearchCriterias()
{
    $search = parent::getSearchCriterias();
    /* display category filtering criteria */
    if(isset($_GET['cat']) && is_numeric($_GET['cat'])) {
        $category = Mage::getModel('catalog/category')->load($_GET['cat']);
        $search[] = array('name'=>'Category','value'=>$category->getName());
    }
    return $search;
}

Answer 2

对此没有快速解决方案.标准搜索和高级搜索使用两种不同的方法进行搜索.

如果比较中的布局,catalogsearch.xml则会看到catalogsearch_advanced_result该块catalogsearch/layer未包含在内.如果从中复制块定义catalogsearch_result_index并更改根模板,3columns.phtml则会抛出各种错误.

此链接转到 Magento 网站应该有所帮助。您需要从目录创建属性。然后查看前端属性（目录>属性）下的设置。
