本文将教会你如何为WordPress添加相关文章功能,并提供了标题列表样式和缩略图样式。相关文章的获取思路是:Tags标签相关>同分类下文章,也就是说,先获取标签相同的文章,如果还达不到数量,就调用该分类下的文章补足。
将下面的代码添加到 single.php 要显示相关文章的位置即可:
<h3>相关文章</h3>
<ul class="related_posts">
<?php
$post_num = 8;
$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(); ?>" title="<?php the_title(); ?>" target="_blank"><?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(); ?>" title="<?php the_title(); ?>" target="_blank"><?php the_title(); ?></a></li>
<?php $i++;
} wp_reset_query();
}
if ( $i == 0 ) echo '<li>没有相关文章!</li>';
?>
</ul>
PS:第四行$post_num = 8;表示显示8篇文章,请根据自己的需要修改。
显示样式需要自己写css,可以参考一下下面的:
.related_posts{margin-top:5px;}
.related_posts li{margin-left:20px;color:#444;list-style:circle;font-size:14px;line-height:26px;padding:0 0 0 5px}
