我的网站有两种自定义类型：拍卖和拍卖。地块通过post_parent 领域我在管理区的地块列表中添加了一个拍卖栏。

function theme_lot_custom_columns($columns){
    $new = array();
    foreach($columns as $key => $value) {
        if ($key==\'date\') {
            // Put the Auction column before the Date column
            $new[\'auction\'] = __(\'Auction\');
        }
        $new[$key] = $value;
    }
return $new;
}
add_filter(\'manage_lot_posts_columns\', \'theme_lot_custom_columns\');

function theme_lot_custom_column($column, $post_id) {
    if ($column === \'auction\'){
        $post = get_post($post_id);
        if ($post->post_parent) {
            $post_parent = get_post($post->post_parent);
            echo \'<a href="\' . get_edit_post_link($post_parent->ID). \'">\' . $post_parent->post_title . \'</a>\';
        }
    }
}
add_action(\'manage_lot_posts_custom_column\', \'theme_lot_custom_column\', 5, 2);

我想让这个拍卖栏按拍卖标题的字母顺序排序。我认为添加以下代码就足够了，但没有。

function theme_lot_sortable_columns($columns) {
    $columns[\'auction\'] = \'auction\';
    return $columns;
}   
add_filter(\'manage_edit-lot_sortable_columns\', \'theme_lot_sortable_columns\');

任何帮助都将不胜感激。

谢谢

function sort_column_by_auction_1357( $vars ){
if ( isset( $vars["orderby"] ) && "auction" == $vars["orderby"] ) {
    $vars = array_merge( $vars, array(
        "orderby" => "auction"
    ) );
}
return $vars;
}
add_filter( "request", "sort_column_by_auction_1357" );

add_action( \'pre_get_posts\', \'as25_column_orderby\' );
function as25_column_orderby( $orderby ) {
 if( ! is_admin() || \'lot\' != $query->get( \'post_type\' ) )
    return;

 $orderby = $query->get( \'orderby\' );

  if( \'auction\' == $orderby ) {
   $query->set( \'orderby\', \'parent\' );
  }
}
