         ->setOrder('price', 'desc')

However in my result price always is first ordering field. can anyone help me, Please ? Thank you so much

Answer 1

$collection->getSelect()
    ->order('field1 asc');

or sort by multiple:

 $collection->getSelect()
    ->order(array('field1 asc', 'price desc'));

Answer 2

To sort using multiple Fields, you can chain calls to the Collection's method addAttributeToSort()

$productCollection->getCollection()
         ->addAttributeToSort('field1', 'asc')
         ->addAttributeToSort('price', 'desc');

Answer 3

on custom resource collection, use addOrder :

Mage::getModel('module/model')->getCollection()
    ->addOrder('first', 'ASC')
    ->addOrder('second', 'DESC')
    ->addOrder('other', 'DESC');

Answer 4

Using:

productCollection->getSelect()->reset(Zend_Db_Select::ORDER); 

Then:

productCollection->getSelect()
            ->order(.......) 

That code will resolve this problem ^ ^

Answer 5

To sort multiple fields you can use

$collection = Mage::getModel(‘module/model_name’)->getCollection()
->addAttributeToSort(‘order’, ‘ASC’)
->addAttributeToSort(‘last_name’, ‘ASC’)
->addAttributeToSort(‘first_name’, ‘ASC’);
