您的代码将字段保存在元框中，但您应该在WPSE中查找add_meta_box + save_post的好例子。

对于列，您不应该替换原件，而是添加您自己的（并且您不需要cb）：

function columns_speaker($old_columns)
{
    $new_columns = array(
        'img'    => 'Immagine',
        'title'  => __('Speakers'),
        'link' => 'link',
    );
    return array_merge( $new_columns, $old_columns );
}

在get_speaker_columns中，您收到了错误消息，但不是$post->ID，而是$post_id。

Wordpress保存metabox dara不起作用
