这是我所有的代码......可能我做错了什么，导致保存功能不起作用。我不知道在哪里以及如何做错了。。我为扬声器选择创建了 CPT 和元框，其中包含多个选择项和另一个元框，其中包含无线电流的详细信息....可能我放了很多元框...我不知道帮帮我

您的代码将字段保存在元框中，但您应该add_meta_box + save_post在 WPSE 上寻找好的示例。

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您遇到错误时，它不是$post->IDbut $post_id。
