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，并且可以与分层导航配合良好。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，我们需要重写这两个模型的一些功能，以使分层导航在高级搜索中工作。

1- 在 local.xml 中的 catalogsearch_advanced_result 标记下添加。

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

用

覆盖catalogsearch/model/Layer.php的prepareProductCollection函数

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;
}

用

覆盖catalogsearch/model/Advanced.php的getProductCollection、getSearchCriterias函数

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;
}
