How to get active filters attribute code in state.phtml

Question

I have been working on Magento C.E 1.9.0.2, and I am implementing custom AJAX product loader, I have achieved everything but I am not able to filter out my product collection as per the selected filters. All I need to have the attribute code of selected filters, which I think can be achieved from state.phtml, where we have the active filters. But, I am not able to get the correct method to to get the active filter's attribute code and current selected values. Need help....

Answer 1

$appliedFilters = Mage::getSingleton('catalog/layer')->getState()->getFilters();

and you get fetch like that

foreach ($appliedFilters as $item) {
    $item->getName(); // Name of the filter
    $item->getLabel(); // Currently selected value
    $item->getFilter()->getRequestVar(); // Filter code (usually attribute code, except category filter, where it equals "cat")
}

Answer 2

Building on the answer above, you need a little more code to use this within the loop of state.phtml:

<?php
$_filters = $this->getActiveFilters();
$appliedFilters = Mage::getSingleton('catalog/layer')->getState()->getFilters();
$attributeCodes = array();

// Loop to get all attribute codes indexed by attribute name
foreach ($appliedFilters as $item) {
    $attributeCodes[$item->getName()] = $item->getFilter()->getRequestVar();
}

// The rendering loop
foreach ($_filters as $_filter) {
    $attributeCode = $attributeCodes[$_filter->getName()];

    if ($attributeCode === 'some_thing') {
        // Something
    }
}
