我正在使用 PHP 开发一个网站,这是我第一次尝试动态菜单。
我正在做的是我为页面创建了一个表格。
表结构如下:
____________________________________________________________________________
|page_id|title|url|content|menu_title|show_on_navuigation|is_sub|parent_page|
|_______|_____|___|_______|__________|___________________|______|___________|
这里is_sub
表示是否是某个主菜单的下拉菜单。parent_page
是子菜单的主菜单。
现在,我想要的是,比如
我创建了 2 个父页面:
About Us
和Test
和 2 个子菜单:测试 aboutus 和 testsub,
测试 aboutus 是 About Us 的 sub,而 testsub 是 test 的 sub。
实际上应该如何查询和循环,以便菜单完美呈现。
提前致谢。
这是我的菜单结构:
<ul>
<li class='has-sub'><a href='#'><span>About Us</span></a>
<ul>
<li><a href='corporateprofile'><span>Corporate Profile</span></a></li>
