   I just started putting together an Events Site
   not all of my posts are events but posts are separated in subcategories

   I added a custom field DateStart

   When I am in a category with events I need to sort them by the custom field. I have seen some code to make a custom call similar to what you do in this plugin but it kills post navigation to older posts.

   here is a deeper explanation
   http://wordpress.org/support/topic/index-or-cat-posts-orderby-meta_key-with-page-navigation?replies=1#post-1668121

   Unfortunately with thousands of posts and many dates i can not use taxonomies they are growing too large now in my Database.

   I am just getting started and my taxonomy is reserved for
   Tags: State, City-State, State-EventType
   Categories with children: State/City/EventType
   Each post has at least 10 custom fields.

   10,208 Posts
   1 Page
   151 Categories
   9,075 Tags

   so its a little crazy heheh
   Thanks if you have any ideas >:o)

   Could you use the orderby=meta_value clause with query_posts?

   After you've registered the DateStart custom field:

   function my_queryable_custom_fields() {
       register_queryable_custom_field( 'DateStart' );
   }
   add_action('init', 'define_queryable_custom_fields');

   You can just go to this URL:

   /category/some-category/?orderby=DateStart

   and it should display sorted posts, even if they don't have a DateStart custom field.

   Hi Scribu,

   First of all, thanks for all the work on WP.
   In the above example, shouldn't the add_action be like:
   add_action('init', 'my_queryable_custom_fields'); instead of define?

   I am looking forward to future versions of the plugin.

   @NPSites: if you only need to sort by ONE custom field than orderby=meta_value can be used without trouble as MichaelH already stated.

   Good luck!
