代码如下,意思很简单,相信诸君看一下就能明白了:

 

<!--  相关推荐  -->
				<div id="Recommend">
					<h2 id="Recommend_title">
						相关推荐:
					</h2>
					<div id="Recommend_list">
						<ul>
							<?php $cat = get_the_category(); foreach($cat as $key=>$category) {$catid = $category->term_id;} $args = array('orderby' => 'rand','showposts' => 6,'cat' => $catid ); $query_posts = new WP_Query(); $query_posts->query($args); while ($query_posts->have_posts()) : $query_posts->the_post(); ?>
							<li>
								<a href="<?php the_permalink();?>" class="Recommend_image" title="点击查看作品【<?php the_title();?>】详情">
									<img src="<?php $full_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full'); echo $full_image_url[0]; ?>" alt="作品【<?php the_title();?><?php echo wp_trim_words( get_the_excerpt(), 40 ); ?>"  style="width:400px;height:200px;" />
								</a>
								<h2 class="Recommend_entrytitle">
									<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
								</h2>
							</li>
							<?php endwhile;?>
							<?php wp_reset_query(); ?>
						</ul>
					</div>
				</div>

 

 

 

PS:   如果还是不行,请在当前主题的functions.php文件当中添加如下代码即可:

 

//文章列表缩略图
function wpforce_featured() {
 
global $post;
 
$already_has_thumb = has_post_thumbnail($post ->ID);
 
if (!$already_has_thumb)  {
 
$attached_image = get_children( "post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=1" );
 
if ($attached_image) {
 
foreach ($attached_image as $attachment_id => $attachment) {
 
set_post_thumbnail($post ->ID, $attachment_id);
 
}
 
}
 
}
 
}  
 
add_action('the_post', 'wpforce_featured');
 
add_action('save_post', 'wpforce_featured');
 
add_action('draft_to_publish', 'wpforce_featured');
 
add_action('new_to_publish', 'wpforce_featured');
 
add_action('pending_to_publish', 'wpforce_featured');
 
add_action('future_to_publish', 'wpforce_featured');
