   i've been working with this code, trying to assign the variable sort in the url (with links) so that i can change the loop based on what the reader wants to sort the posts by... day, week, month, or year when they click on various links.

   i don't know why it won't work... it is getting the variable fine, but for some reason, assigning $date and then calling it later is not working.

   here's my code:

   <?php
   $sort= isset($_GET['sort']) ? $_GET['sort'] : "A";
   if($sort == "A") {
   $date = '-24 hours';
   }
   elseif($sort == "B") {
   $date = '-7 days';
   }
   elseif($sort == "C") {
   $date = '-30 days';
   }
   elseif($sort == "D") {
   $date = '-365 days';
   }
   else {
   $date = '-24 hours';
   }
   
   function filter_where($where = '') {
   $where .= " AND post_date > '" . date('Y-m-d H:i:s', strtotime($date)) . "'";
   return $where;
   }
   add_filter('posts_where', 'filter_where');
   query_posts($query_string); ?>
   
   <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

   and then it continues on...

   i'm not very good with php, and i appreciate all your help with this. thank you

   i figured it out... i needed to put the variable within the function. ok, so i guess if you are looking for a way to use links to change the query of your loop, then this code could do the trick...

   <?php
   function filter_where($where = '') {
   $sort= isset($_GET['sort']) ? $_GET['sort'] : "A";
   if($sort == "A") {
   $date = '-24 hours';
   }
   elseif($sort == "B") {
   $date = '-7 days';
   }
   elseif($sort == "C") {
   $date = '-30 days';
   }
   elseif($sort == "D") {
   $date = '-365 days';
   }
   else {
   $date = '-24 hours';
   }
   $where .= " AND post_date > '" . date('Y-m-d H:i:s', strtotime($date)) . "'";
   return $where;
   }
   add_filter('posts_where', 'filter_where');
   query_posts($query_string); ?>
   
   <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

   and then it continues on to what you want to do...

   hope this could help someone who wants to do something similar
