现在的问题是如何从数据库中获取类别并输出到下拉菜单？

                    {html_options values=$cat_menu.cid output=$cat_menu.category  selected=$smarty.session.show_category}
      </select> 

在 browse.php 中，我看到以下代码，其中分配了 cat_menu

$smarty->assign('cat_menu', get_list('category', 'category'));

但我找不到 get_list 函数。

我需要有关如何从数据库中获取类别信息的帮助

谢谢

Answer 1

我很确定该函数在您的 config.php 文件中。因此 include ("include/config.php");
