   Hello!

   I've implemented the Page of Posts example from the Codex's "Pages" page, and like it a great deal. However, I was wondering how can one make it so that multiple categories can show up, instead of just the one.

   Here's the code:

   <?php
   if (is_page() ) {
   $category = get_post_meta($posts[0]->ID, 'category', true);
   }
   if ($category) {
     $cat = get_cat_ID($category);
     $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
     $post_per_page = 4; // -1 shows all posts
     $do_not_show_stickies = 1; // 0 to show stickies
     $args=array(
       'category__in' => array($cat),
       'orderby' => 'date',
       'order' => 'DESC',
       'paged' => $paged,
       'posts_per_page' => $post_per_page,
       'caller_get_posts' => $do_not_show_stickies
     );
     $temp = $wp_query;  // assign orginal query to temp variable for later use
     $wp_query = null;
     $wp_query = new WP_Query($args);
     if( have_posts() ) :
   		while ($wp_query->have_posts()) : $wp_query->the_post(); ?>

   I'm thinking there's probably a better way of doing it instead of using a custom field, and having very rudimentary php knowledge I'm not sure how to figure it out. I also don't mind hard-coding the Categories if need be, as the cats are few and there won't be many additions.

   Any thoughts?

   give the value of your custom field "categorie" multiple categorie ID's seperated by commas.
   and try it with this code (not tested):
   

   <?php
   if (is_page() ) {
   $category = get_post_meta($posts[0]->ID, 'category', true);
   }
   if ($category) {
     $multicats = explode(',', $category);
     $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
     $post_per_page = 4; // -1 shows all posts
     $do_not_show_stickies = 1; // 0 to show stickies
     $args=array(
       'category__in' => $multicats,
       'orderby' => 'date',
       'order' => 'DESC',
       'paged' => $paged,
       'posts_per_page' => $post_per_page,
       'caller_get_posts' => $do_not_show_stickies
     );
     $temp = $wp_query;  // assign orginal query to temp variable for later use
     $wp_query = null;
     $wp_query = new WP_Query($args);
     if( have_posts() ) :
   		while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
