I'm having problems applying a default sort order to the product collection for the listing page. When some conditions are met I want to sort by 'region' and then by 'price'. I have added the following in app/code/local/Mage/Catalog/Block/Product/List/Toolbar.php.

  public function setCollection($collection)
    $this->_collection = $collection;

    $limit = (int)$this->getLimit();
    if ($limit) {
    if(Mage::registry('current_category')->getName() == 'France'){
        $this->_collection->setOrder(array('region', 'price'), $this->getCurrentDirection());
        if ($this->getCurrentOrder()) {
            $this->_collection->setOrder($this->getCurrentOrder(), $this->getCurrentDirection());
    return $this;

This sorts by region successfully but not by price. I did read somewhere that different resources are used by price than other attributes when using them for sorting. If this is the case it makes sense because when I substituted price with name - $this->_collection->setOrder(array('region','name'), 'asc'); I get the collection sorted by region and then by name.

To confirm, both attributes are set yes to - Used in Product Listing and Used for Sorting in Product Listing. Any suggestions on getting price to work with region?

I think the problem here is that there are some special code that needs to be run to sort by price.

If you take a look into the function setOrder on the model Mage_Catalog_Model_Resource_Product_Collection you will see that it does something "special" when dealing with the attribute price.

public function setOrder($attribute, $dir = 'desc')
    if ($attribute == 'price') {
        $this->addAttributeToSort($attribute, $dir);
    } else {
        parent::setOrder($attribute, $dir);
    return $this;

My suggestion for you is to follow this example and try adding the sort by price in the same fashion and by calling addAttributeToSort.

    hey thanks for the answer. I've won't have a chance to really look at it for a while but so far even knowing that price needs a different filter function using it with another filter is complicated. Thanks again tho, hopefully it will set me right! Commented Jan 28, 2015 at 11:57

After going through Mage_Catalog_Model_Resource_Product_Collection as @DavidManners suggested I eventually found a solution that appears to work

   $this->_collection->getSelect()->order(array('region', 'price_index.final_price'), $this->getCurrentDirection());
