I am building a custom API for SOAP and I want to get the filters for the collection.
$collection = Mage::getModel('catalog/category')->load($category_id)->getProductCollection()->setStoreId(1)->setPageSize(20);
I am adding some filters also to the $collection.
This is the collection that I have and I want to get all filters and values so I can display them into the mobile APP that is making this custom SOAP call.
On this moment I manage to get all attributes that are in layer from a category, but I need to be from a collection because the collection is going to be filtered.
Can someone help me with this?
