带缩略图的相关文章代码

带缩略图的相关文章代码网上应该很多啊，本主题其实是自带相关文章的，只不过是没有缩略图显示啊；至于文章显示缩略图的代码，可以参考本站，这里就不在说明了啊.
实现的效果请看下面的图片

一、主要代码如下，可以新建一个relatedpost.php

<div class="Related_Posts">
	<ul>
		<?php
$post_num = 5;
$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),
		'ignore_sticky_posts' => 1,
		'orderby' => 'comment_date',
		'posts_per_page' => $post_num
	);
	query_posts($args);
	while( have_posts() ) { the_post(); ?>
		<li>
			<a href="<?php the_permalink(); ?> " rel="nofollow"><?php post_thumbnail( 90,90 ); ?></a>
			<div class="Related_Posts_tittle"><a class="Related_Posts_tittle" href="<?php the_permalink(); ?>" ><?php the_title(); ?></a></div>
		</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),
		'ignore_sticky_posts' => 1,
		'orderby' => 'comment_date',
		'posts_per_page' => $post_num - $i
	);
	query_posts($args);
	while( have_posts() ) { the_post(); ?>
		<li>
			<a href="<?php the_permalink(); ?> " rel="nofollow"><?php post_thumbnail( 90,90 ); ?></a>
			<div class="Related_Posts_tittle"><a class="Related_Posts_tittle" href="<?php the_permalink(); ?>" ><?php the_title(); ?></a></div>
		</li>
 
	<?php $i++;
	} wp_reset_query();
}
if ( $i  == 0 )  echo '<li>没有相关文章!</li>';
?>
	</ul>
</div>

注明：有可能你使用其他方式获取缩略图，请替换

<?php post_thumbnail( 90,90 ); ?>

为你使用的函数...

二、在文章页面的地方引入relatedpost.php即可

<div class="relatedposts">
<div class="xg_title"><h3>相关文章</h3></div>
<?php include('relatedpost.php'); ?>
</div>

三、加入适当的css,以下仅演示，请自行修改

.Related_Posts {
	margin-top: 9px;
	margin-left: 5px;
	width: 610px
}
.Related_Posts_tittle {
	margin-top: -3px;
	line-height: 17px;
	color: #515151 !important;
	font-size: 12px !important;
	width: 96px;
	height: 32px;
	overflow: hidden
}
.Related_Posts li {
	float: left;
	margin: 0 32px 0 0
}
.Related_Posts ul li img {
	width: 90px;
	height: 90px;
	background: #F4F4F4;
	border: 1px solid #D8D8D8;
	padding: 2px
}
.xg_title{background:none repeat scroll 0 0 #EEEEEE;color:#333333;height:34px;line-height:30px;padding:0 0 0 15px;font-size:14px}
.xg_title h3{color:#333333;font-size:14px;font-weight:700;line-height:34px;margin:0;padding:0}
