wordpress tag标签改造id显示加后缀html显示

wordpress tag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：

/* 标签以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;

}
