很多时候我们在分类文章列表访问时，侧边栏的小工具都是显示的所有站点的热门标签，那如果才能显示当前分类列表的标签呢，下面大挖给大家提供一个解决方案，可以显示当前的分类标签，需要在wordpress主题的核心文章funtion里面添加如下的代码。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
function get_category_tags($args) { global $wpdb; $tags = $wpdb->get_results (" SELECT DISTINCT terms2.term_id as tag_id, terms2.name as tag_name FROM $wpdb->posts as p1 LEFT JOIN $wpdb->term_relationships as r1 ON p1.ID = r1.object_ID LEFT JOIN $wpdb->term_taxonomy as t1 ON r1.term_taxonomy_id = t1.term_taxonomy_id LEFT JOIN $wpdb->terms as terms1 ON t1.term_id = terms1.term_id, $wpdb->posts as p2 LEFT JOIN $wpdb->term_relationships as r2 ON p2.ID = r2.object_ID LEFT JOIN $wpdb->term_taxonomy as t2 ON r2.term_taxonomy_id = t2.term_taxonomy_id LEFT JOIN $wpdb->terms as terms2 ON t2.term_id = terms2.term_id WHERE t1.taxonomy = 'category' AND p1.post_status = 'publish' AND terms1.term_id IN (".$args['categories'].") AND t2.taxonomy = 'post_tag' AND p2.post_status = 'publish' AND p1.ID = p2.ID ORDER by tag_name "); $count = 0; if($tags) { foreach ($tags as $tag) { $mytag[$count] = get_term_by('id', $tag->tag_id, 'post_tag'); $count++; } } else { $mytag = NULL; } return $mytag; } |
其次，将下面调用输出代码，添加到主题archive.php模板适当位置：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<?php $cat= single_cat_title('', false); $args = array( 'categories' => get_cat_ID($cat)); $tags = get_category_tags($args); $content .= "<ul class='cat-tag'>"; if(!empty($tags)) { foreach ($tags as $tag) { $content .= "<li><a href=\"".get_tag_link($tag->term_id)."\">".$tag->name."</a></li>"; } } $content .= "</ul>"; echo $content; ?> |
最后，再适当加上样式即可：
|
1 2 3 4 5 6 7 8 |
.cat-tag{ float: left; width: 100%; } .cat-tag li a{ float: left; margin: 0 5px; } |
