根据我使用的主题 cuteWp 并参考下面链接文章，通过代码实现了包含缩略图的相关文章展示。获取相关文章的策略为：标签 > 分类 > 随机。最终效果如下图：

参考自：代码 WordPress 实现相关文章展示

实现过程如下：

1、找到放置相关文章的代码位置，加入如下内容：

<!-- 相关文章 start-->
<hr class="wp-block-separator" style="margin-top:20px"/>
<h4 style="margin-top:30px;">
  <i class="fa fa-heart-o" aria-hidden="true"></i> 猜您喜欢
</h4>
<ul>
	<?php
		$post_num = 5; // 默认展示 5 篇文章，可以自行修改~
		$exclude_id = $post->ID;
		$posttags = get_the_tags(); $i = 0;
		if ( $posttags ) {
			$tags = ''; foreach ( $posttags as $tag ) $tags .= $tag->term_id . ',';
			$args = array(
				'post_status' => 'publish',
				'tag__in' => explode(',', $tags),
				'post__not_in' => explode(',', $exclude_id),
				'caller_get_posts' => 1,
				'orderby' => 'comment_date',
				'posts_per_page' => $post_num,
			);
			query_posts($args);
			while( have_posts() ) { the_post(); ?>
			   <li><a rel="bookmark" href="<?php the_permalink(); ?>">
				     <?php if ( has_post_thumbnail($recent_post) ) : ?>
			          <?php echo get_the_post_thumbnail($recent_post, 'lwq-post-list-image' ); ?>
		         <?php else: ?>
			          <img src="<?php echo esc_url(get_template_directory_uri() . '/assets/images/post-25x25.jpg'); ?>" class="attachment-lwq-post-list-image size-lwq-post-list-image wp-post-image"/>
		         <?php endif; ?>
		     <?php the_title(); ?></a></li>
		     <?php $exclude_id .= ',' . $post->ID; $i ++;} wp_reset_query();
		}
		if ( $i < $post_num ) {
			$cats = ''; foreach ( get_the_category() as $cat ) $cats .= $cat->cat_ID . ',';
			$args = array(
				'category__in' => explode(',', $cats),
				'post__not_in' => explode(',', $exclude_id),
				'caller_get_posts' => 1,
				'orderby' => 'comment_date',
				'posts_per_page' => $post_num - $i
			);
			query_posts($args);
			while( have_posts() ) { the_post(); ?>
				<li><a rel="bookmark" href="<?php the_permalink(); ?>">
					   <?php if ( has_post_thumbnail($recent_post) ) : ?>
				         <?php echo get_the_post_thumbnail($recent_post, 'lwq-post-list-image' ); ?>
		         <?php else: ?>
				         <img src="<?php echo esc_url(get_template_directory_uri() . '/assets/images/post-25x25.jpg'); ?>" class="attachment-lwq-post-list-image size-lwq-post-list-image wp-post-image"/>
		         <?php endif; ?>
             <?php the_title(); ?></a></li>
				<?php $i++;} wp_reset_query();
    }
  ?>
  <?php
		if ( $i  == 0 ) { echo '<p style="color: #aaa">没有相关文章，为您推荐以下随机文章！</p>';
		$args = array( 
			'post__not_in' => explode(',', $exclude_id),
			'orderby' => 'rand', 
			'post_status' => 'publish',
			'posts_per_page' => $post_num
		);
		$rand_posts = get_posts( $args );
		foreach( $rand_posts as $post ) : ?>
			<li><a href="<?php the_permalink(); ?>">
				<?php if ( has_post_thumbnail($recent_post) ) : ?>
					<?php echo get_the_post_thumbnail($recent_post, 'lwq-post-list-image' ); ?>
				<?php else: ?>
					<img src="<?php echo esc_url(get_template_directory_uri() . '/assets/images/post-25x25.jpg'); ?>" class="attachment-lwq-post-list-image size-lwq-post-list-image wp-post-image"/>
				<?php endif; ?>
				<?php the_title(); ?></a></li>
		<?php endforeach; ?>
	<?php } ?>
</ul>
<!-- 相关文章 end-->

2、样式调整

在主题 style.css 下添加如下样式：

/* 相关文章样式*/
.entry-footer ul li{padding:3px 0;text-decoration:none;}
.entry-footer ul li a{font-size:14px;}
.entry-footer ul li a:hover{color: #5552C3;text-decoration:none}
.entry-footer ul li span{float:right;color:#999;font-size:12px; margin-right:60px;text-align:center;display:inline-block;}

这样就可以了。
