   Hey

   I'm trying to add a class/id to each item that comes out of wp_list_pages and wp_nav_menu. I got as far as doing a preg_replace on current classes on it and thats fine I can get a class in.

   My problem is that I need the new class to be a variable that gets added to after each item is outputted. So a count++ after each page item. Using a variable is fine but its a count after each one thats causing me hastle.

   Essentially what I'd like to end up with is something along these lines..

   <ul>
   <li class="item1">List item</li>
   <li class="item2">List item</li>
   <li class="item3">List item</li>
   <li class="item4">List item</li>
   </ul>

   What I've got so far in the functions file is
   

   $idcounter = 0;
   function add_markup_cat($output) { // add a class to menu-item
   	global $idcounter;
       return preg_replace('/menu-item /', $idcounter, $output, 20);
   }
   add_filter('wp_nav_menu', 'add_markup_cat');

   I'm thinking its something along the lines of a for each but I just can't figure it out.

   The navigation code I'm using is this that I found online..
   

   <?php
   
   $parent_id = $post->post_parent;
   $parent = get_post($parent_id);
   if($parent->post_parent){
   $top_level_id = $parent->post_parent;
   }else if($post->post_parent){
   $top_level_id = $post->post_parent;
   }else{
   $top_level_id = $post->ID;
   }
   if($parent->post_parent){
   $children = wp_list_pages("title_li=&child_of=19&echo=0");
   $my_id = $parent->post_parent;
   }else if($post->post_parent){
   $children = wp_list_pages("title_li=&child_of=19&echo=0");
   $my_id = $post->post_parent;
   }else{
   $children = wp_list_pages("title_li=&child_of=19&echo=0");
   $my_id = $post->post_parent;
   }
   if ($children) {
   
   $post_id_7 = get_post($my_id);
   $title = $post_id_7->ID;
   
   ?>
   
   <ul class="twocol">
   <?php echo $children; ?>
   </ul>

   If anyone can help at all I'd really really appreciate it! Bangin my head off the wall here!

   Thanks a million for your time

   oh i meant to say i had the count++ in here
   

   $idcounter = 0;
   function add_markup_cat($output) { // add a class to menu-item
   	global $idcounter;
       return preg_replace('/menu-item /', $idcounter, $output, 20);
   	$idcounter ++;
   }
   add_filter('wp_nav_menu', 'add_markup_cat');

   but it just gives one value back rather than one for each item.

   Any help, greatly appreciated!

   in place of:
   <?php echo $children; ?>

   you could try and use:

   <?php
   $kiddy_bits = explode('<li ', $children);
   $children = ''; $i = 1;
   foreach($kiddy_bits as $bits) :
   if($bits) { $children = $children.'<li class="item'.$i.'" '.$bits; $i++; }
   endforeach;
   echo $children;
   ?>
