本章主要介绍wordpress顶级菜单函数add_menu_page与子菜单函数add_submenu_page的组合使用。
wordpress顶级菜单函数add_menu_page()
add_menu_page( $page_title, $menu_title, $capability, $menu_slug, $function, $icon_url, $position );
//page_title页面title标签信息
//$menu_title 菜单标题
//capability 权限
//menu_slug 别名
//function 执行函数
//icon_url 菜单图标url地址
//position 此菜单项在菜单中的位置，用数字来表示
wordpress子菜单函数add_submenu_page()
add_submenu_page( $parent_slug, $page_title, $menu_title, $capability, $menu_slug, $function );
//parent_slug-父级菜单项的别名
//page_title--页面的title信息
//menu_title-菜单标题
//capability-权限
//menu_slug-别名
//function-执行的函数
后台很多页面都是通用的，比如广告位列表，广告位添加、修改，广告列表，广告添加、修改，所以可以归纳下
