If you have our free Template Assistant add on installed you can do it using that under 'Property Hive > Settings > Template Assistant > Search Results'.
Alternatively, to change the default sort order of properties shown in search results you can add the following to your theme’s functions.php file:
add_filter('propertyhive_default_search_results_orderby', 'change_default_order'); function change_default_order( $orderby ) { if ( ( isset($_REQUEST['department']) && $_REQUEST['department'] != 'commercial' ) || ( !isset($_REQUEST['department']) && get_option( 'propertyhive_primary_department' ) != 'commercial' ) ) { return 'price-asc'; // e.g price-asc, date, modified etc } else { return $orderby; } }
