Magento – Reset layer product collection filter in search

blockscatalogsearchlayered-navigationsearch

I am writing a block which subclasses Mage_Catalog_Block_Layer_Filter_Category to display a list of products in each category. To do this I apply addCategoryFilter() to the layer product collection for each layer filter item, first using clear() to remove any other filters. So I end up with $this->getLayer()->getProductCollection()->clear()->addCategoryFilter($category) for each item.

The problem is the last-displayed category filter is not being cleared before the rest of the page renders. So the sidebar layered navigation is still filtered by it. How can I clear it?? I have tried doing $this->getLayer()->getProductCollection->clear() in _afterToHtml() but with no luck. Any help much appreciated.

The problem is getLayer is a singleton and holds afaik one collection. There is no easy way to achieve what you want. You can unset the whole collection (maybe) after doing whatever you are doing (which I didnt understand)

Magento – Speed up layered navigation filter in Magento

For each attribute you have in Magento and that is marked as filtrable, it will make a call to getAllOptions() of attribute source model. Even if there is no filter results for it, it will invoke attribute option collection load. Possible solution other optimization tips described here:

Also make sure the layered navigation block is cached ( many simple extensions just skip this)

Try solr based layered navigation as well.

Server performance is also important.

For layered Navigation you have to:

Extend

app/code/core/Mage/CatalogSearch/Model/Layer.php

to your custom module.

And over ride prepare collection function:

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

        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);
    }

    return $this;
}
