$categoryid = 43;



$layer = Mage::getModel("catalog/layer");



$category = Mage::getModel("catalog/category")->load($categoryid);



$layer->setCurrentCategory($category);



$attributes = $layer

    ->getFilterableAttributes()

    ->addDisplayInAdvancedSearchFilter()

    ;



Mage::log($attributes->getSelect());



foreach ($attributes as $attribute) {

    echo $attribute->getAttributeCode(). " ". $attribute->getStoreLabel() ."<br/>";

}

I want tho filters attributes which is used in layered navigation and used in advance search. When I print query the result query working fine but print the attribute filter they give only getFilterableAttributes.

The getFilterableAttributes method class Mage_Catalog_Model_Layer load collection first then I use addDisplayInAdvancedSearchFilter cause will effect after load collection.

I want to know is there any method load collection after loading the method. Any one face these kind of problem then please help how it works.

In class Mage_Catalog_Model_Layer method getFilterableAttributes have following code.

public function getFilterableAttributes()

    {

        $setIds = $this->_getSetIds();

        if (!$setIds) {

            return array();

        }

        /** @var $collection Mage_Catalog_Model_Resource_Product_Attribute_Collection */

        $collection = Mage::getResourceModel('catalog/product_attribute_collection');

        $collection

            ->setItemObjectClass('catalog/resource_eav_attribute')

            ->setAttributeSetFilter($setIds)

            ->addStoreLabel(Mage::app()->getStore()->getId())

            ->setOrder('position', 'ASC');

        $collection = $this->_prepareAttributeCollection($collection);

        $collection->load();



        return $collection;

    }

When I add $collection->addDisplayInAdvancedSearchFilter() before $collection->load() but its wokring fine. Like This.

public function getFilterableAttributes()

    {

        $setIds = $this->_getSetIds();

        if (!$setIds) {

            return array();

        }

        /** @var $collection Mage_Catalog_Model_Resource_Product_Attribute_Collection */

        $collection = Mage::getResourceModel('catalog/product_attribute_collection');

        $collection

            ->setItemObjectClass('catalog/resource_eav_attribute')

            ->setAttributeSetFilter($setIds)

            ->addStoreLabel(Mage::app()->getStore()->getId())

            ->setOrder('position', 'ASC');

        $collection = $this->_prepareAttributeCollection($collection);

        $collection = $this->addDisplayInAdvancedSearchFilter();

        $collection->load();



        return $collection;

    }

Its work fine.

I don't want to rewrite Mage_Catalog_Model_Layer Model.

Thanks

After Load collection doesnt make new database request. You can use
$collection->clear(); .

And add filters to returned collection.
