How to add the Digg button to selected articles only

As you know, Digg is a powerful social website which can send more than 10,000 visitors to your blog if your article is pushed to the front page.

We can easily add the Digg button to our posts. All you need to do is simply copy the code and paste it into your template file and then the Digg button will appear in every post. But what if you only want the Digg button to appear in selected posts only?

How to make the Digg button appear in selected posts only

So, I am going to create a custom function and use custom fields to decide whether the Digg button will appear or not.

Open your template’s functions.php and paste the following codes before the ending tag ‘?>‘.

/* Return a Digg button */
function digg_button()
{
    global $post;

    $link=js_escape(get_permalink($post->ID));
    $title=js_escape($post->post_title);
    $text=js_escape(substr(strip_tags($post->post_content), 0, 350));        

    $button="
    <script type='text/javascript'>
    digg_url = '$link';
    digg_title = '$title';
    digg_skin = '$mode';
    digg_bodytext = '$text';
    </script>
    <script src='http://digg.com/tools/diggthis.js' type='text/javascript'></script>";

    if (get_post_meta($post->ID, 'digg-button', true) == 1)
        echo $button;
    else
        echo '';
}

Then, open your single.php, and add this code at the place where you want Digg button appear.

<?php digg_button(); ?>

So now that you have added the necessary code, simply add a custom field called “digg-button” with value 1 to the post that you want Digg button to appear.

Now, you can easily show or hide the Digg button using a custom field!
