I have looked around the interwebs to find the easiest way to add a digg button with the sumbit feature to wordpress, but I could only find plugins, or other methods that seemed to complicated.

So here is the most simple solution for adding digg to you blog. The following is code from the digg website;

<script type=”text/javascript”>
digg_url = ‘WEBSITE_URL’;
</script>
<script src=”http://digg.com/tools/diggthis.js” type=”text/javascript”></script>

All you need to do is replace ‘WEBSITE_URL’ with ‘<?php the_permalink() ?>’ and place the code within the LOOP. (I put mine in the Main Index Template after the comments – you can edit this via wordpress in the theme editor.)

To show the Digg button when viewing a single post, you must also add it to the ‘Single Post’ template (also under theme editor). I placed this second set of code after the ‘tags’ and before the ‘postmetadata’.

Its as simple as that. For additional options you can add the following;

digg_bgcolor = ‘#ff9900’; (Background Colour)
digg_skin = ‘compact’; (Smaller Button)
digg_window = ‘new’; (Open in New Window)

For additonal options have a look at the digg tools website. (link)
