WordPress hack: Use includes in your posts or pages

The first step is to paste the following code in your function.php file:

function digwp_includeContentShortcode($atts) {

  $thepostid = intval($atts[postidparam]);
  $output = '';

  query_posts("p=$thepostid&post_type=page");
  if (have_posts()) : while (have_posts()) : the_post();
    $output .= get_the_content($post->ID);
  endwhile; else:
    // failed, output nothing
  endif;
  wp_reset_query();

  return $output;

}

Once done, you can use the shortcode in your posts or pages, with the following syntax:

[digwp_include postidparam=XXXX]

postidparam is the ID of the post you want to include.

Credits goes to Chris Coyier for this awesome shortcode!
