How is your date meta stored (what format)? If it is a Unix timestamp, you could set the orderby parameter of your query to meta_value_num. – pogoking Jan 9 at 3:51
time stamp,well I try this: SELECT (SELECT ABS(m1.meta_value-UNIX_TIMESTAMP(NOW())) from wp_postmeta AS m1 WHERE m1.meta_key='st_time' AND m1.post_id=p.ID) AS dis FROM wp_posts AS p, wp_postmeta AS m WHERE p.ID = m.post_id ORDER BY dis,the query_post() may not have so much! – liying Jan 9 at 6:41

Try to use WP_Query instead of using the SQL. You can get the reference here.

Simple example would be like:

$args = array(
   'post_type' => 'my_custom_post_type',
   'meta_key' => 'date',
   'orderby' => 'meta_value_num',
   'order' => 'ASC',
   'meta_query' => array(
       array(
           'key' => 'event_date',
           'value' => date()
       )
   )
 );
 $query = new WP_Query($args);

and use a simple while loop to iterate through the results.

See this for more info on meta query parameters.

Well,I know this useful WP_Query,but the main point is I want to sort by the difference between meta_value and another object(like now time)! – liying Jan 10 at 2:17
