wordpress二次开发tags改id显示，后缀加html，伪静态格式对seo特别友好.
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：
最终显示格式：id+html方式展示
add_action('generate_rewrite_rules','tag_rewrite_rules');
add_filter('term_link','tag_term_link',10,3);
add_action('query_vars', 'tag_query_vars');
function tag_rewrite_rules($wp_rewrite) {
$new_rules = array(
'tag/(d+)/feed/(feed|rdf|rss|rss2|atom).html' => 'index.php?tag_id=$matches[1]&feed=$matches[2]',
'tag/(d+)/(feed|rdf|rss|rss2|atom).html' => 'index.php?tag_id=$matches[1]&feed=$matches[2]',
'tag/(d+)/embed.html' => 'index.php?tag_id=$matches[1]&embed=true',
'tag/(d+)/page/(d+).html' => 'index.php?tag_id=$matches[1]&paged=$matches[2]',
'tag/(d+).html' => 'index.php?tag_id=$matches[1]',
);
$wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}
function tag_term_link($link,$term,$taxonomy) {
if($taxonomy=='post_tag') {
return home_url('/tag/'.$term->term_id.'.html');
}
return $link;
}
function tag_query_vars($public_query_vars) {
$public_query_vars[] = 'tag_id';
return $public_query_vars;
}
