I’ve had no trouble creating a new WP query to output my events on my site but I am trying to figure out how to organize the events by their UNIX timestamp in the database, not by the date that WordPress created the events.

I can’t seem to wrap my head around the thing.. any advice?

  2. Better use pre_get_posts:

    function ta_modify_main_query($query) {
   if ($query->is_main_query()) {
       $query->set('orderby', 'meta_value_num');
       $query->set('meta_key', '_liked');
       $query->set('order', 'DESC');
   }
}

add_action( 'pre_get_posts', 'ta_modify_main_query' );
