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。

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。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!

为了检查自己是否属于同一类别,无论是顶级父级还是子级父级,只需将全局cPath添加到函数的escope并与cPath_new进行比较即可。

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(); }
