In functions.php:

if ( function_exists('register_sidebar')) {
        register_sidebar(array(
        'before_widget' => '<div id="%1$s" class="widget %2$s">',
        'after_widget' => '</div>',
        'before_title' => '',
        'after_title' => '',
        'name' => 'Left'
    ));
        register_sidebar(array(
         'before_widget' => '<div id="%1$s" class="widget %2$s">',
         'after_widget' => '</div>',
         'before_title' => '',
         'after_title' => '',
         'name' => 'Right'
   ));
}

Datei right_sidebar.php:

<!-- begin sidebar -->
<div id="RightSidebar">
<?php if ( !function_exists('dynamic_sidebar')
        || !dynamic_sidebar('Right') ) : ?>
        This theme needs dynamic sidebars
<?php endif; ?>
</div>
<!-- end sidebar -->

Datei left_sidebar.php:

<!-- begin sidebar -->
<div id="LeftSidebar">
<?php if ( !function_exists('dynamic_sidebar')
        || !dynamic_sidebar('Left') ) : ?>
        This theme needs dynamic sidebars
<?php endif; ?>
</div>
<!-- end sidebar -->

Einbauen in z.B. header.php oder footer.php mit:

<? include (TEMPLATEPATH . '/right_sidebar.php'); ?>
