Custom sidebar in single.php

Programming in php: Custom sidebar in single.php on newest questions tagged php – Stack Overflow

I use this code to disply custom single.php pages (by category) in wordpress
and it works fine.

 get_header(); ?>

        <div id="container">
            <div id="content" role="main">

            <?php
              $post = $wp_query->post;

              if (in_category('4')) {
                  include(TEMPLATEPATH.'/loop-single-recept.php');
              } elseif (in_category('7')) {
                  include(TEMPLATEPATH.'/loop-single.php');
              } else {
                  include(TEMPLATEPATH.'/loop-single.php');
              }
                ?>

            </div><!-- #content -->
        </div><!-- #container -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

But I also want to disply custom sidebars in each single.php page.
