Wordpress previous post shortlink

Question

Hey guys so far I have this code that gives me the full link to my previous post

<?php $prevPost = get_previous_post(FALSE);
if($prevPost) {?>
<div class="prev1" onclick="javascript:_gaq.push(['_trackSocial', 'Nav', 'Prev-Thumb']);">
<?php previous_post_link('%link',"«", FALSE); ?>
</div>
<?php } ?>

But I want the shortlink instead of the full link

How can I accomplish that ?

Thank you in advance

Swap out your existing code with the following.

<?php
// Get the previous post.
$previous_post = get_previous_post();

// Check a post was found.
if ( $previous_post ) : ?>
    <div class="prev1" onclick="javascript:_gaq.push(['_trackSocial', 'Nav', 'Prev-Thumb']);">
        <a href="<?php echo wp_get_shortlink( $previous_post->ID ); ?>" title="Permalink to previous post">&laquo;</a>
    </div>
<?php endif; ?>
