Next & Previous Post Thumbnails
-
I am building a custom theme and i’m using the post thumbnail function to show next and previous posts in my sidebar.
Here is the code i’m using
<div class="previmg"> <?php $post_thumbnail = get_post_meta($post->ID, 'post_thumbnail', true); if ($post_thumbnail) { ?> <a href="<?php previous_post_link(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php echo $post_thumbnail; ?></a> <?php } else { ?> <?php $prevPost = get_previous_post(); $prevthumbnail = get_the_post_thumbnail($prevPost->ID, array(66,66) ); previous_post_link('%link',''.$prevthumbnail.'', TRUE); ?> <?php } ?> </div> <div class="nextimg"> <?php $post_thumbnail = get_post_meta($post->ID, 'post_thumbnail', true); if ($post_thumbnail) { ?> <a href="<?php next_post_link(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php echo $post_thumbnail; ?></a> <?php } else { ?> <?php $nextPost = get_next_post(true); $nextthumbnail = get_the_post_thumbnail($nextPost->ID, array(66,66) ); next_post_link('%link',''.$nextthumbnail.'', TRUE); ?> <?php } ?> </div>
I am having a problem in showing a default thumbnail (for example a empty thumbnail with a cross) when you get to the very last post or the very first post.
Any ides on how to do this?
