Sort items by 2 params

Hi,

In my page :

http://catalogue.cappiello.fr/items/browse?sort_field=Dublin+Core%2CTitle

I would like to sort with title first and then Identifier, is it posible???

Right now, I’m doing it with:

$sortLinks[__(‘Title’)] = ‘Dublin Core,Title,Identifier’;

in browse.php but it’s not working…

Any idea???

You can’t do that out of the box: you can only sort by one field at a time.

A plugin could do this pretty easily though since plugins can use hooks and filters to change the queries at the SQL level and do whatever they want with sorting.
