推荐答案

下面的补丁将在高级"搜索结果中显示分层导航，并且可以很好地与分层导航一起使用.分层导航和搜索结果基于两个独立的产品集合显示，一个由 catalogsearch/Model/Layer.php 创建，另一个由 catalogsearch/Model/Advanced.php 创建.因此，我们需要覆盖这两种模型的少量功能，以使分层导航在高级"搜索中起作用.

The patch below will display the layered navigation in Advanced search result and will work fine with layered navigations. The layered navigation and search result are displayed based on two separate product collections, one created by catalogsearch/Model/Layer.php and the other by catalogsearch/Model/Advanced.php.So we need to override few functions of both these models to make layered nav work in Advanced search.

1-在您的local.xml中的 catalogsearch_advanced_result 标记下添加.

1- In your local.xml under catalogsearch_advanced_result tag add.

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

使用

Override prepareProductCollection function of catalogsearch/model/Layer.php with

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;
}

使用

Override getProductCollection, getSearchCriterias function of catalogsearch/model/Advanced.php with

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;
}
