Modifying the Autotrackback Plugin

Hi all,

I’ve been trying to modify the Auto-trackback Plugin in order not to double trackback urls by pushing the “Save and Continue Editing” button when posting.

The plugin download location is here.
https://dev.wp-plugins.org/browser/auto-trackback-by-category/trunk/autotrackback.php?rev=1524&format=raw

By default, the plugin adds preconfigured trackback urls to the field altohugh the same urls are already in there. I mean the dipulicated urls are shown when you push the “Save and Continue Editing” button.

So here is what I did but this does not work.

Changin the line 144,

$the_uri = "$old_uri $auto_uri";

to the following.

$the_uris = array_merge(explode(' ', $old_uri), explode(' ', $auto_uri));
$the_uris = array_unique($the_uris);
$the_uri = implode(' ', $the_uris);

Does anybody happen to know why this doesn’t work or the solution for this?

Your information will be appreciated.
