PHP:【商城后台管理系统】部署角色管理,角色添加,菜单权限,删除角色功能

2021年06月18日 15:01:40阅读数:617博客 / JiaJieChen/ ThinkPHP6.0商城项目

PHP:【商城后台管理系统】部署角色管理,角色添加,菜单权限,删除角色功能

一.角色管理界面

①首页

②角色添加

③角色编辑

④角色删除

二.部署流程

  • 部署流程
    • 后端采用thinkphp6.0框架,角色管理看似简单,但是在菜单权限这一块是很难得,为什么难呢?因为要设计菜单无限级构造树,还要将无限极菜单构造树递归遍历成二级菜单,这样才好将菜单渲染到视图层,在代码块注释中将有这些问题的解决方案。
    • 前端采用Layui框架
