Basically i am playing with a plugin that allows future-dated posts on archive pages. My question is broader than this specific functionality, but everyone likes some context.

I have my head around many of the plugin development concepts, but must be missing something very basic.

I can successfully rewrite a query that gives me the results i want like this:

function modify_where( $where ) {
  global $wp_query;
    // define $year, $cat, etc
  if( is_archive() ) {
    $where = "  AND YEAR(wp_posts.post_date)='".$year."' AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN ('".$cat."') AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'future')";
  }
  return $where;
}

add_filter('posts_where', 'catCal_where' );

However, if i attempt to create a new WP_Query('different_query_stuff') after the main loop the new query uses the same WHERE statement outlined above.

The question is : What am I missing?

Thanks.
