不知道为什么我的自定义帖子类型没有添加_POST_META

时间：2019-12-21 作者：Shaikh Nadeem

我尝试了太多的方法来解决问题，但无法解决，我认为我的save\\u car\\u data\\u meta（$post\\u id）不用于调试是用于在我的第一个函数{car\\u data\\u meta\\u box\\u output（）}上执行var\\u dump，然后保存函数工作，否则它不工作

在第二个文件中Car_Data_Meta_Boxes_Init 生产线：

add_action( \'save_car_data_meta\', array( $this, \'save_meta_boxes\' ), 10, 1 );

您绑定到自定义操作save_car_data_meta 但这个动作是在内部触发的save_meta_boxes 这就是为什么它永远不会被触发，除非你这样做var_dump(Car_Data_Meta_Box_Data::save_car_data_meta(158)); 在metabox渲染逻辑中手动触发save meta函数。

因此，您需要在Car_Data_Meta_Boxes_Init 将此行分类

add_action( \'save_car_data_meta\', array( $this, \'save_meta_boxes\' ), 10, 1 );具有

add_action( \'save_post_{YOUR_POST_TYPE_NAME}\', array( $this, \'save_meta_boxes\' ), 10, 1 );

更换{YOUR_POST_TYPE_NAME} 使用精确的自定义帖子类型名称，可能是car 这样你就可以save_post_car 操作名称。

看见https://developer.wordpress.org/reference/hooks/save_post_post-post_type/ 供参考。

（另外，当您从中读取数据值时，最好清理用户输入。）$POST 保存时。）
