magento override sort order of product list by subcategories
- by dardub
I'm setting up a new store using 1.4.1
I'm trying sort the products in the list by the subcategories they belong to. At the top of list.phtml is
$_productCollection=$this->getLoadedProductCollection();
I tried adding sort filters to that by adding the line
$_productCollection->setOrder('category_ids', 'asc')->setOrder('name', 'asc');
I also tried addAttributeToSort instead of setOrder. This doesn't seem to have any effect. I'm guessing that $_productCollection is not a model I can sort in this manner. I have been digging around trying to find the correct place to apply the sort method without any success.
Can someone tell me the proper place to do this?
