只显示一次的提示信息怎么传递?
比如登录,
登录错误时候,可以在当前页面输出示错误(密码错误之类的)。
登录成功跳转到首页。想在首页显示一行(登录成功提示信息),这个怎么传递?
cookie? 感觉怪怪的~ 显示的时候后马上删除吗?
而且这个信息只显示一次

在Web开发中有一种比较成熟的做法就是把信息放到flash
域中,该信息会在返回或者跳转或显示
在页面中,通常都是基于session的,会自动完成显示后清空
PS:不太懂PHP
下面的是搜索出来的不知道好用不(关键词:php flash message
)

前端就直接在页面显示,一般在head 导航下面, main-content 上面。
类似于 <div id="“notice”"></div>
需要显示的时候就向里面添加内容。
后端使用 session 在 controller 跟 view 间传递,用完注意清空。
用flash 或者用 localstorage 都是可以的。
