In layered navigation view, my themes show which filters are currently applied to the view. However, it doesn't show which category you are currently in.
I guess I have to edit the state.phtml, but what would I add in order to get current category?
You can use
magento registry variable
Mage::getSingleton('catalog/layer')->getCurrentCategory() for getting current category object
Second option is best
you can get the current category like that
