Magento 1.9.2 Fügen Sie die Ebenennavigation hinzu, um die Suche zu erweitern

Ich habe die folgenden 3 Schritte für die erweiterte Suchebenennavigation befolgt, aber es funktioniert nicht. Irgendeine Idee / Anregung ODER Wie implementiere ich Layer-Navigation in der erweiterten Suche?

1) In unserer local.xml unter catalogsearch_advanced_result Tag hinzufügen.

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

2) Überschreiben Sie die prepareProductCollection-Funktion von catalogsearch / model / Layer.php mit

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) Überschreiben Sie die Funktion getProductCollection, getSearchCriterias von catalogsearch / model / Advanced.php mit

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;
}

Erstellen Sie eine neue Datei im lokalen oder überschreiben Sie das Ebenenmodell in der Datei app / code / local / Mage / CatalogSearch / Model / Layer.php des lokalen Moduls und ändern Sie die Funktion 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;
    }

Danach machen Sie dasselbe mit app / code / local / Mage / CatalogSearch / Model / Advanced.php und ändern die Funktionen getProductCollection und getSearchCriterias

    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;
    }

Hier in der unteren Ebene ist die Navigation für die erweiterte Suche vorbereitet. Die Produktsammlung muss nun diese Ebenennavigation mithilfe der Theme-XML-Datei anzeigen. Bearbeiten Sie also die Datei c atalogsearch.xml Ihres Themas und fügen Sie den folgenden Code hinzu Etikett.

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

Um die geschichtete Navigation in der erweiterten Suche anzuzeigen, müssen Sie einige Änderungen in der Kerndatei vornehmen.

Folgen Sie diesem Link Ich habe den gleichen Prozess verwendet und es funktioniert gut.

Befolgen Sie die folgenden Schritte, um die Layer-Navigation für die erweiterte Suche hinzuzufügen: 1- Die Layer-Navigation ist für die erweiterte Suche vorbereitet. Die Produktsammlung muss nun diese Layer-Navigation mithilfe der Theme-XML-Datei anzeigen.

    <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;
}
