wordpress - 我有一组 CMB2 字段，我正在将 url 元导入到，它适用于单个字段，但不适用于分组

Question

我有一个需要添加 url 元数据的字段，到目前为止，我有这个允许我将元数据添加到单个字段。

add_action( 'cvm_post_insert', 'add_extra_meta_data', 40, 3 );

函数 add_extra_meta_data( $post_id, $video, $theme_import ){

if ( get_post_status( $post_id ) == 'draft' ) {
    $url = cvm_video_url($video['video_id']);
    if($url){
        update_post_meta($post_id, 'exercise_gallery_embed', $url);
    }
}

}

但是当我使用分组字段时，输入字段名称看起来更像这样，因为它正在堆叠 id

add_action( 'cvm_post_insert', 'add_extra_meta_data', 40, 3 );

函数 add_extra_meta_data( $post_id, $video, $theme_import ){

if ( get_post_status( $post_id ) == 'draft' ) {
    $url = cvm_video_url($video['video_id']);
    if($url){
        update_post_meta($post_id, 'exercise_gallery[0][exercise_gallery_embed]', $url);
    }
}

}

虽然我可以在自定义字段中看到数据，但它不会将 url 添加到元框，欢迎任何帮助或指针。以下是正在使用的字段组。

    // Repeatable group.
    $gallery_group = $cmb->add_field(
