我正在尝试从“wpcf7\\u mail\\u sent”挂钩（未登录用户从前端提交的表单）调用操作。它不起作用了。如果我从钩子调用相同的方法，即连接到“save\\u post”钩子的方法，它会工作。我从管理面板更新帖子。

代码示例：

插件#1（此部分有效）

function event_updated( $post_ID, $post, $update ) {
/*
    $post_ID(int) - Post ID.
    $post(WP_Post) - Post object.
    $update(bool) - Whether this is an existing post being updated or not.
*/
    $post_type = get_post_type($post_id);

    if ( "event_post_type" != $post_type ) return;

    do_action(\'update_event_hook\', $post_ID, $post);
}
add_action( \'save_post\', \'event_updated\', 10, 3 );

add_action( \'wpcf7_mail_sent\', \'set_event_booked\' );
function set_event_booked($contact_form) {
$submission = WPCF7_Submission::get_instance();

if ( $submission ) {
    $posted_data = $submission->get_posted_data();
    $id = $posted_data[\'post-id\'];
    $new_id = $posted_data[\'event-id\'];

    $post = new \\stdClass;
    $post->ID = intval($posted_data[\'post-id\']);
    $post->post_type = \'event_post_type\';

    update_post_meta($new_id, \'event_booked\', \'on\');
    try {
        do_action(\'update_event_hook\', $id, $post);
    } catch (Exception $e) {
        $error_message = $e->getMessage();
        $log_message = \'Add reservaion ERROR: \'. $error_message;
    }
}

class API_sync_class
{
    private static $options;

    public static function Init()
    {
        self::$options = get_option("api_sync");

        if (self::$options[\'use\']) {

            add_action(\'update_event_hook\', array(\'API_sync_class\', \'AddEditReservation\'), 10, 2);
        }
    }

    public static function AddEditReservation($post_id, $post)
    {
    API_sync_class::DebugToFile(\'AddEditReservation method:\');

    $type = get_post_type($post_id);
    if ($type && ($type != \'event_post_type\')) {
        return;
    }

    $appdata = self::AppData($post);
    API_sync_class::DebugToFile(\'Data to be sent to API (prepared)\');
    API_sync_class::DebugToFile($appdata);

        ....... Some other code of meethod
    }
