我有一个插件，可以将元盒写入特定页面。它可以很好地编写元数据库，并且一切正常。。。直到我保存。save\\u帖子没有接到电话，我不知道为什么。这是我的_构造中的代码
class Plg_Admin_Meta {
public static function start() {
return new self();
}
public function __construct() {
$this->plugin_url = WP_CONTENT_URL . \'/plugins/\' . basename(dirname(__FILE__));
$this->plugin_dir = dirname(__FILE__);
add_action(\'admin_init\', array($this, \'_admin_init\'));
add_action(\'save_post\', array($this, \'_save_post\'), 99);
}
元框是由自定义字段创建的，如果编辑自定义字段文本区域，它会很好地保存，但我希望它保存从元框输入的数据。无论出于何种原因，save\\u post都不会启动。我尝试在我的\\u save\\u POST函数的开始处放置一个骰子（var\\u dump（$\\u POST）），但它甚至没有启动。
这是我的\\u save\\u post函数
public function _save_post($post_id) {
//die(dump_var($_POST));
update_post_meta($post_id, \'content__service_overviews\', "test2");
// Post meta isn\'t sent for autosaves
if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) {
return;
}
}
Plg_Admin_Meta::start();
如您所见，我现在只是手动尝试更新字段，但函数甚至没有被调用。
