我希望有人可以帮我修改类别链接创建。我已经对它进行了修改，并且在大多数情况下都取得了成功，但最后一点是杀了我。

我只修改了从第34行开始的tep_show_category函数。我没有收到任何错误。然而，它也没有按照我想要的方式运作，我似乎无法弄清楚如何运作。 ;）
我想要发生的是，如果一个类别是父猫，则分配标签。如果是小猫，请指定标签。除非当前选择了子类别，否则不使用h标记。
父母和孩子的工作都很好。但是我很难看到subcat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。它似乎在链接创建中使用$ first_id + $ last_id来构建cPath参数。即indxp.phhp中的1_4？cPath = 1_4。所以，我尝试采用使用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！

为了检查您是否属于同一类别，无论它是顶级父级还是子级父级，您只需将全局cPath添加到函数的escope中并将其与cPath_new进行比较。
cPath来自application_top，因此您可以将其作为全局访问。
if (cPath != cPath_new){ this_is_not_the_current_categorie(); }
else { this_is_the_current_categorie(); }
