我希望有人可以帮我修改类别链接的创建。我已经对其进行了修改，并且大部分都成功了，但是最后一点让我很生气。

我只修改了从第 34 行开始的函数 tep_show_category。我没有收到任何错误。但是，它也没有按照我想要的方式运行，我似乎无法弄清楚如何。;)
我想要发生的是，如果类别是父猫，请分配标签。如果是儿童猫，请分配标签。除非当前选择了子类别，否则不要使用 h 标记。
为父母和孩子工作得很好。但是，我很难查看子目录是否是当前页面。
我只是不确定我应该在哪里查看是否选择了 subcat。似乎在链接创建中它使用 $first_id + $last_id 来构建 cPath 参数。即 indxp.phhp?cPath=1_4 中的 1_4。所以，我尝试过使用 isset 的方法来查看 $last_id 是否为空......但没有这样的运气。
提前致谢！
