Layered navigation: intval on price filter

Question

I can see $prices = array_map('floatval', $prices); in Mage_Catalog_Model_Layer_Filter_Price.

I was wondering if I could intval without creating my own block, etc..?

Answer 1

There is no event dispatched in the methods that use floatval (loadPrices, loadPreviousPrices, loadNextPrices) so you have to create your own model that rewrites these methods. All you need is a single model (so no blocks)

class [Namespace]_[Module]_Model_Catalog_Layer_Filter_Price 
    extends Mage_Catalog_Model_Layer_Filter_Price {
    public function loadPrices($limit, $offset = null, $lowerPrice = null, $upperPrice = null) {
        $prices = parent::loadPrices($limit, $offset, $lowerPrice, $upperPrice);
        if ($prices) {
            $prices = array_map('intval', $prices);
        }
        return $prices;
    } 
    //do the same for loadPreviousPrices and loadNextPrices
}
