我已经创建了“project”posttype和“project\\u category”texonomy。现在你要做的就是添加新项目，并添加你想在自定义posttype名称之前显示的项目类别，permalink意味着在2016类别中添加任何帖子。并将链接设置为自定义posttype“/%postname%/”。在函数中尝试此代码。php文件并检查。你也可以自定义posttypeI收到这个“www.abc”。com/2016/projects/test permalink/\'。

   add_filter( \'pre_get_posts\', \'query_post_type\' );
    function query_post_type( $query ) {
      if ( is_category() ) {
    $post_type = get_query_var( \'post_type\' );
    if ( $post_type ) {
        $post_type = $post_type;
    } else { $post_type = array( \'nav_menu_item\', \'post\', \'projects\'         ); // End if().
    }
    $query->set( \'post_type\',$post_type );
    return $query;
     }
  }

   function custom_post_type() {

// Set UI labels for Custom Post Type
$labels = array(
    \'name\'                => _x( \'projects\', \'Post Type General Name\', \'namo\' ),

使用\'custom-post-type-permalinks\' 插件

并将“/%年%/%帖子名%/”插入到自定义帖子类型文本字段中，它将显示如下链接：
