function change_order_for_events( $query ) {
    //only show future events and events in the last 24hours
    $yesterday = date('Ymd');

    if ( $query->is_main_query() && (is_tax('dt_portfolio_category') || is_post_type_archive('dt_portfolio')) ) {
        $query->set( 'meta_key', 'sub_seminars_0_start_date' );
        $query->set( 'orderby', 'meta_value_num' );
        $query->set( 'order', 'ASC' );

        //Get events after 24 hours ago
        $query->set( 'meta_value', $yesterday );
        $query->set( 'meta_compare', '>' );

       //Get events before now
       //$query->set( 'meta_value', current_time('timestamp') );
       //$query->set( 'meta_compare', '<' );
    }

}

add_action( 'pre_get_posts', 'change_order_for_events' );

this code in function.php will sort your posts based on a specific meta key value.
sub_seminars_0_start_date

I have created a custom taxonomy Seminar Venues but the above code won’t work for that even after adjustin the parameters.
