我想知道的是，类别是否为“news”add/news event/before it。

更新：尚未生效。

多亏了@jas，我想这段代码可以做到，但我想我需要重写规则才能让它工作，我不擅长regex，所以我不知道怎么做，这是我迄今为止尝试过的。

  add_filter( \'post_link\', \'custom_permalink\', 10, 3 );
  function custom_permalink( $permalink, $post, $leavename ) {

// Get the categories for the post
 $category = get_the_category($post->ID);
 if (  !empty($category) && $category[0]->cat_name == "news" ) {
    $permalink = trailingslashit( home_url(\'news-events/\' . $category. \'/\' . $post->post_name .\'/\' ) );
 }
return $permalink;

}

 function rewrite_rules( $wp_rewrite ) {
     $new_rules[\'news-events/^news/([^/]+)/?\'] = \'index.php?name=$matches[1]\'; //change \'test\' to your category slug
     $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
    return $wp_rewrite;
 }
  add_action(\'generate_rewrite_rules\', \'rewrite_rules\'); 

我的网站有这样的永久链接结构“site.com/en/postname1”，我有帖子类别“category1，category2，…”我想将我的帖子分类改为“site.com/en/category1/custom-text/postname1或site.com/en/category2/custom-text/postname2”。有可能吗？请帮帮我。

/%category%/%postname%

add_filter( \'post_link\', \'custom_permalink\', 10, 3 );
function custom_permalink( $permalink, $post, $leavename ) {

    // Get the categories for the post
    $category = get_the_category($post->ID);
  if (  !empty($category) && $category[0]->cat_name == "news" ) {
        $permalink = trailingslashit( home_url(\'news/\'. $post->post_name .\'/\' ) );
  }
    return $permalink;
}
