   Hi guys,

   I have been working on a custom template and wanted to include a trackback link at the bottom of each page and post. I found a theme that already includes this functionality and copied the following code into my "comments.php" theme file.

   <?php if(pings_open()) : ?>
   	<span class="addtrackback"><a href="<?php trackback_url(); ?>"><?php _e('Trackback', 'inove'); ?></a></span>
   <?php endif; ?>

   But the links that are generated do not appear to be correct.

   On the page: http://localhost:8080/blog/?page_id=2
   The trackback link is: http://localhost:8080/blog/wp-trackback.php?p=2

   If the trackback link is clicked I get the following error message in XML format:

   <response>
   	<error>1</error>
   	<message>I really need an ID for this to work.</message>
   </response>

   On the page: http://localhost:8080/blog/?p=16
   The trackback link is: http://localhost:8080/blog/wp-trackback.php?p=1

   Which I think is probably correct.

   Could you please advise me on this issue?

   Many thanks,
   Lea Hayes

   Seems the get_trackback_url does not take into consideration when a page is displayed and not a post as it always returns
   

   $tb_url = get_option('siteurl') . '/wp-trackback.php?p=' . $id;

   The page trackback should be changed to
   

   '/wp-trackback.php?page_id=' . $id;

   which worked fine for me.

   To fix this issue, add the following to your functions.php file.
   

   add_filter ('trackback_url', 'fix_page_trackback_url', 15);
   if (!function_exists('fix_page_trackback_url')):
   function fix_page_trackback_url ($trackback_url)
   {
     if (is_page()):
       return str_replace ('?p=','?page_id=', $trackback_url);
     else:
       return $trackback_url;
     endif;
   }
   endif; //fix_page_trackback_url

   Hope this helps...

   Note: not sure if it still works when permalink structure is customized!
