Magento 1.9.2 Adicione camada de navegação para avançar na pesquisa

Segui as 3 etapas a seguir para navegação avançada na camada de pesquisa, mas ela não está funcionando. Alguma idéia / sugestão OU Como implementar a navegação de camadas na pesquisa avançada?

1) Em nosso local.xml, na tag catalogsearch_advanced_result, adicione.

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

2) Substitua a função prepareProductCollection de catalogsearch / model / Layer.php por

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;
}

3) Substitua getProductCollection, função getSearchCriterias de catalogsearch / model / Advanced.php por

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;
}

Crie um novo arquivo no local ou substitua o modelo de camada no módulo local app / code / local / Mage / CatalogSearch / Model / Layer.php e altere a função prepareProductCollection

    public function prepareProductCollection($collection)
    {
        if(Mage::helper('catalogsearch')->getQuery()->getQueryText())
        {
            $collection->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
            ->addSearchFilter(Mage::helper('catalogsearch')->getQuery()->getQueryText())
            ->setStore(Mage::app()->getStore())
            ->addMinimalPrice()
            ->addFinalPrice()
            ->addTaxPercents()
            ->addStoreFilter()
            ->addUrlRewrite();
        }
        else
        {
            $collection->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes());
            $attributes = Mage::getSingleton('catalog/product')->getAttributes();
            foreach($attributes as $attribute)
            {
                $attribute_code = $attribute->getAttributeCode();
                if($attribute_code == "price")
                continue;
                if (empty($_REQUEST[$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] . "%"));
            }
            $collection->setStore(Mage::app()->getStore())
            ->addMinimalPrice()
            ->addFinalPrice()
            ->addTaxPercents()
            ->addStoreFilter()
            ->addUrlRewrite();
            Mage::getSingleton('catalogsearch/advanced')->prepareProductCollection($collection);    
        }
        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);
        return $this;
    }

Depois que fazer mesmo com locais / Mago / CatalogSearch / Modelo / Advanced.php e mudança app / code / getProductCollection e getSearchCriterias funções

    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 = $this->_searchCriterias;
        if(isset($_GET['cat']) && is_numeric($_GET['cat'])){
            $category = Mage::getModel('catalog/category')->load($_GET['cat']);
            $search[] = array('name'=>'Category','value'=>$category->getName());
        }
        return $search;
    }

Aqui na camada abaixo, a navegação é preparada para a coleta avançada de produtos de pesquisa. Agora, é necessário exibir essa camada usando o arquivo xml do tema, para editar o arquivo c atalogsearch.xml do tema e adicionar o código abaixo em tag.

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

Para mostrar a navegação em camadas na pesquisa avançada, é necessário fazer algumas alterações no arquivo principal.

Siga este link. Utilizo o mesmo processo e está funcionando bem.

Para adicionar navegação de camada à pesquisa avançada, siga as etapas abaixo: 1- Na navegação abaixo da camada, está preparada para a coleção de produtos de pesquisa avançada, agora é necessário exibir essa navegação de camada usando o arquivo xml do tema, para editar o arquivo catalogsearch.xml do tema e adicionar o código abaixo na tag.

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

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

    public function prepareProductCollection($collection)
    {   
        $bac= Mage::helper('catalogsearch')->getQuery()->getQueryText();
        if($bac)
        {
            $collection->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
            ->addSearchFilter(Mage::helper('catalogsearch')->getQuery()->getQueryText())
            ->setStore(Mage::app()->getStore())
            ->addMinimalPrice()
            ->addFinalPrice()
            ->addTaxPercents()
            ->addStoreFilter()
            ->addUrlRewrite();

        } 
        else 
        {

            $collection->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes());
            $attributes = Mage::getSingleton('catalog/product')->getAttributes();
            foreach($attributes as $attribute)
            {
                $attribute_code = $attribute->getAttributeCode();
                if($attribute_code == "price")
                continue;
                if (empty($_REQUEST[$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] . "%"));
            }
            $collection->setStore(Mage::app()->getStore())
            ->addMinimalPrice()
            ->addFinalPrice()
            ->addTaxPercents()
            ->addStoreFilter()
            ->addUrlRewrite();
            Mage::getSingleton('catalogsearch/advanced')->prepareProductCollection($collection);    
        }
        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);
        return $this;
    }

3. Than after changing getProductCollection and getSearchCriterias function as below in app/code/core/Mage/CatalogSearch/Model/Advanced.php file.

<?php 
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 = $this->_searchCriterias;
    if(isset($_GET['cat']) && is_numeric($_GET['cat'])){
        $category = Mage::getModel('catalog/category')->load($_GET['cat']);
        $search[] = array('name'=>'Category','value'=>$category->getName());
    }
    return $search;
}
