All the applied filters are stored in layer state object. You can easily retrieve them by using the following snippet:
所有应用的过滤器都存储在图层状态对象中。您可以使用以下代码段轻松检索它们：
$appliedFilters = Mage::getSingleton('catalog/layer')->getState()->getFilters();
It will return you an array of filter item objects. You can retrieve name and applied value of a single filter item by doing something like this:
它将返回一组过滤器项目对象。您可以通过执行以下操作来检索单个过滤器项的名称和应用值：
foreach ($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")
}
