I'd like to make a simple "multiple choices per attribute" addon for the layered navigation.
Simply put, I want
to work. For this to happen, I need to
- convert attribute keys into IDs (e.g. led_color -> ID #2)
- alter the product collection load procedure to handle attribute value arrays and not just plain values
Because I can't see any of that happening in Mage/Catalog/CategoryController, where would I go or which class/method would I need to overload?
I found this repo https://github.com/mercator/catalin_seo which does what we want but it's very difficult to make any sense of it as the author overloads a ton of classes. I am hoping for a simpler solution.
