Magento – Change Layered Navigation Filter Output

filterlayered-navigation

I'm working on a problem at the moment in the layered navigation. I need to change how the filters are working. Currently they are called like so;

    $_filters = $this->getFilters();
    foreach ($_filters as $_filter):
    //various mark up and calls are made here

Then to output the individual options the following is used.

   $_filter->getHtml()

I need to find another way of getting this data, preferably unformatted. I am able to get each filters attribute code like so;

  $_filter->getFilterOptions()->getCode()

But I can't figure out how to use this to get the options belonging to each filter attribute.

The two most important pieces of information that I need are the option name and id. After this I can work everything out.

The output of $_filter->getHtml() can be found in app/design/frontend/base/default/template/catalog/layer/filter.phtml (filter items).

Magento – Layered Navigation: Price filter on custom collection

Price filter uses a bit different SQL query. It tries to avoid joining with the product entity table and replace it with the price index.

As you are using layered navigation module, you need to modify class app\code\local\Amasty\Shopby\Model\Mysql4\Price.php instead of the magento default.

Best place to add filters to product collection programmatically is

Mage_Catalog_Model_Layer::prepareProductCollection()

not phtml template.

At the moment catalog/product/list.phtml is rendered, product collection is already loaded and if you don't plan to render products it is better not to load them at all.

The logic should sound like:

public function prepareProductCollection($collection)
{
    $collection
        ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
        ->addMinimalPrice()
        ->addFinalPrice()
        ->addTaxPercents()
        ->addUrlRewrite($this->getCurrentCategory()->getId());

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

    // your custom filter
    if ($this->_areFiltersApplied()) {
        $this->_addInStockFilter($collection);
    }

    return $this;
}

protected function _areFiltersApplied() {
    return count($this->getState()->getFilters()) > 0;
}

protected function _addInStockFilter($collection) {
    Mage::getModel('cataloginventory/stock_status')->addIsInStockFilterToCollection($collection);
}
