我已经激活了Order 我的“公文包”CPT的功能，并已根据各自的Order 我提供的价值观。

不幸的是，我发现这段代码锁定了“公文包”项目在admin中的显示顺序；我无法切换Title 升序/降序功能，也无法按此列表排序Date.

我的目标是使用Order 但我仍然希望能够利用Title/Date 在管理中排序。

//add order column to admin listing screen
function add_new_portfolio_column($post_columns) {
    $post_columns[\'menu_order\'] = "Order";
    return $post_columns;
  }
  add_action(\'manage_edit-portfolio_columns\', \'add_new_portfolio_column\');


//show custom order column values
function show_order_column($name){
    global $post;
   
    switch ($name) {
      case \'menu_order\':
        $order = $post->menu_order;
        echo $order;
        break;
     default:
        break;
     }
  }
  add_action(\'manage_portfolio_posts_custom_column\',\'show_order_column\');


//make column sortable
function order_column_register_sortable($columns){
    $columns[\'menu_order\'] = \'menu_order\';
    return $columns;
  }
  add_filter(\'manage_edit-portfolio_sortable_columns\',\'order_column_register_sortable\');


//Sort post archive by menu_order
add_action( \'pre_get_posts\', \'mpe_portfolio_sort_order\'); 
function mpe_portfolio_sort_order($query){
    if(is_archive() ):
       $query->set( \'order\', \'ASC\' );
       $query->set( \'orderby\', \'menu_order\' );
    endif;    
};

我在“portfolio”CPT“supports”数组中加入了“page attributes”

add_action( \'pre_get_posts\', \'mpe_portfolio_sort_order\'); 
function mpe_portfolio_sort_order($query){
    if(is_archive() && ! is_admin() ):
       $query->set( \'order\', \'ASC\' );
       $query->set( \'orderby\', \'menu_order\' );
    endif;    
};
