我有 3 个问题（需要帮助）：
- 我不知道，如何运行这个插件（给我致命错误）请检查我的脚本（我是初学者）
- 需要帮助管理页面设置 APIkey 并选择调用 url http://xxx.CZ或http://xxx.SK的语言（此页面尚未编写脚本）
- 如何将我的插件管理页面添加到 woocommerce 管理页面？
该插件适用于 Woocommerce。(http://heureka.cz/or .sk/dotaznik/"Clients API set up in admin page in woocommerce"/"Customers email"/"Order ID"/"bought Products ID"/)当客户订单完成时，它应该调用特定的 URL 。
我是 PHP 和 Wordpress 的初学者。谢谢大家帮助我。
