下面给大家介绍怎么为WordPress上下篇文章链接添加缩略图，希望对需要的朋友有所帮助！
为WordPress上下篇文章链接添加缩略图
大部分WordPress主题都会在正文下面添加上下篇文章的链接，可以通过下面的代码给这个链接再加个缩略图，让其更醒目。
将下面代码添加到正文模板文件的适当位置即可。
代码一
默认调用文章100×100的特色图像。
<div id="post-nav" class="navigation"><?php $prevPost = get_previous_post(true);if($prevPost) ?><div class="nav-box previous"><?php previous_post_link('« « Previous Post:', 'yes'); ?><?php $prevthumbnail = get_the_post_thumbnail($prevPost->ID, array(100,100) );?><?php previous_post_link('%link',"$prevthumbnail <p>%title</p>", TRUE); ?></div><?php $nextPost = get_next_post(true);if($nextPost) ?><div class="nav-box next" style="float:right;"><?php previous_post_link('» » Next Post:', 'yes'); ?><?php $nextthumbnail = get_the_post_thumbnail($nextPost->ID, array(100,100) ); ?><?php next_post_link('%link',"$nextthumbnail <p>%title</p>", TRUE); ?></div><?php ?></div>配套样式
#post-nav{clear: both; height: 100px; margin: 0 0 70px;}#post-nav .nav-box{background: #e9e9e9; padding: 10px;}#post-nav img{float: left; margin: 0 10px 0 0;} #post-nav p{margin: 0 10px; font-size: 11px; vertical-align: middle;}#post-nav .previous{float: left; vertical-align: middle; width: 300px; height: 120px;}#post-nav .next{float: right; width: 300px; height: 120px;}代码二
除了调用特色图像，并显示文章发表时间，稍加修改还可以添加更多的文章信息，包括自定义缩略图、文章简要等。
<div id="post-nav"><?php $prevPost = get_previous_post(true);if($prevPost) {$args = array('posts_per_page' => 1,'include' => $prevPost->ID);$prevPost = get_posts($args);foreach ($prevPost as $post) {setup_postdata($post);?><div class="post-previous"><a class="previous" href="<?php the_permalink(); ?>">« Previous Story</a><a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('thumbnail'); ?></a><h4><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4><small><?php the_date('F j, Y'); ?></small></div><?phpwp_reset_postdata();} //end foreach} // end if $nextPost = get_next_post(true);if($nextPost) {$args = array('posts_per_page' => 1,'include' => $nextPost->ID);$nextPost = get_posts($args);foreach ($nextPost as $post) {setup_postdata($post);?><div class="post-next"><a class="next" href="<?php the_permalink(); ?>">Next Story »</a><a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('thumbnail'); ?></a><h4><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4><small><?php the_date('F j, Y'); ?></strong></div><?phpwp_reset_postdata();} //end foreach} // end if?></div>
