wordpress文章tag标签默认链接是用中文字显示的,中文状态下是不利于seo优化的,不过有的是我们自定义设置英文拼音的。今天小编着重介绍一下怎么把链接改成数字id.html(无需插件)。
打开主题functions.php,在最下面插入以下代码:
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;
}
现在相关链接已经修改好了,但是页面是会出现404,所以这时需要重新打开后台工具中“固定链接”页面重新保存即可!
