我的wordpress网站有两种用户类型，我希望每个用户都能拥有独立的喜好统计信息。我已经创建了作者角色和订阅者角色，并为每个帖子成功获得了两个单独的评论线程。每个职位和职位评论都必须对每个角色具有相同的功能。我正在使用的插件是wp-ulike。
我已经尝试过修改许多不同的插件。最后的办法就是编写一个自定义的插件。我尝试了多次尝试来了解wp-ulike进程的喜欢程度，以便添加另一种喜欢类型。我已经尽力在表中添加一列并对其进行写入和读取，但是中间的所有处理都丢失了。
这是该类的名称：

我可以轻松实现它，使其接受该类的两个实例，但是这样做行得通吗？还是会导致共享名称变量失败？我可以简单地为第二个类创建新的表字段和HTML输出吗？
预期结果将是一组用户与另一组用户的喜欢表不同。
