wordpress tags标签改造id显示加后缀html显示

wordpress tags标签改造id显示加后缀html显示，对seo来说是特别友好的。
使用文本编辑器打开当前主题目录下的 functions.php,添加以下 php 代码：

1. /* 标签以id+html方式展示（www.LXH5068.com）*/
2. add_action('generate_rewrite_rules','tag_rewrite_rules');
3. add_filter('term_link','tag_term_link',10,3);
4. add_action('query_vars', 'tag_query_vars');
5. function tag_rewrite_rules($wp_rewrite) {
6. $new_rules = array(
7. 'tag/(\d+)/feed/(feed|rdf|rss|rss2|atom).html' => 'index.php?tag_id=$matches[1]&feed=$matches[2]',
8. 'tag/(\d+)/(feed|rdf|rss|rss2|atom).html' => 'index.php?tag_id=$matches[1]&feed=$matches[2]',
9. 'tag/(\d+)/embed.html' => 'index.php?tag_id=$matches[1]&embed=true',
10. 'tag/(\d+)/page/(\d+).html' => 'index.php?tag_id=$matches[1]&paged=$matches[2]',
11. 'tag/(\d+).html' => 'index.php?tag_id=$matches[1]',
12. );
13. $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
14. }
15. function tag_term_link($link,$term,$taxonomy) {
16. if($taxonomy=='post_tag') {
17. return home_url('/tag/'.$term->term_id.'.html');
18. }
19. return $link;
20. }
21. function tag_query_vars($public_query_vars) {
22. $public_query_vars[] = 'tag_id';
23. return $public_query_vars;
