Next & Prev Post
-
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 if(get_adjacent_post(false, '', true)) : // check for the existance of a prev post ?> <?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 } ?> <?php else : // if no prev post ?> <img src="<?php bloginfo('template_url'); ?>/images/empty.jpg"/> <?php endif; // end of the prev post check ?> </div> <div class="nextimg"> <?php if(get_adjacent_post(false, '', false)) : // check for the existance of a next post ?> <?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 } ?> <?php else : // if no prev post ?> <img src="<?php bloginfo('template_url'); ?>/images/empty.jpg"/> <?php endif; // end of the prev post check ?> </div>
I’m having a issue when I get the the forth post. It seems to just show an empty image which I dont want.
Any ideas on how to fix it?
Thanks
