php - 需要帮助设置谷歌日历 API

Question

我正在使用 CAR Wash 预订系统一个 codecanyon 插件，我想让我的插件以两种方式工作，谷歌日历同步。我想在这个文件中触发一个函数，所以当我在谷歌日历中进行更改时，它们应该在 WP 插件中更新。这是一个 Car Was 预订系统。

插件中的主要代码如下：

<?php


class CBSGoogleCalendar
{

    $this->token=get_option(PLUGIN_CBS_CONTEXT.'_google_calendar_token','');
    $this->expiration=get_option(PLUGIN_CBS_CONTEXT.'_google_calendar_expiration','');
    $this->settings=json_decode(get_option(PLUGIN_CBS_CONTEXT.'_google_calendar_settings',''));
}

/**************************************************************************/
