修改如何在bm_categories.php中构建类别

我希望有人能帮我修改分类链接的创建。我已经对它进行了修改，并且在很大程度上取得了成功，但是这最后一点让我很痛苦

bm_categories.php的内容：

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。然而，它的运行方式也不是我想要的，而且我似乎不知道如何运行。；）

我想做的是，如果一个类别是一个父类，则分配标记。如果它是一只小猫，请指定标签。除非当前选择了子类别，否则不要使用h标记

对于父母和孩子来说，他们的工作都很好。但是，我很难让它查看子类别是否为当前页面

我只是不确定应该在哪里查看subcat是否被选中。在链接创建中，它似乎使用$first_id+$last_id来构建cPath参数。i、 e indxp.phhp？cPath=1_4中的1_4。所以，我尝试使用isset的方法来查看$last_id是否为空……但没有这样的运气

提前谢谢

要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进行比较即可

cPath来自应用程序_top，因此您可以作为全局访问它

if (cPath != cPath_new){ this_is_not_the_current_categorie(); } 
else { this_is_the_current_categorie(); }
