消费者页面:(本篇随笔)
(1)会显示店主的头像
(2)当前用户发送信息显示在右侧,接受的信息,显示在左侧
店主或客服页面:(下一篇随笔)
(1)在左侧有一个列表 ,会显示所有与店主对话的顾客;该列表可以移动;有新消息时会提示;也可以清空该聊天记录
(2)点击列表里的顾客进入右边的对话框界面,显示与该顾客的聊天信息
在实现功能之前,来说一下我用到的两张表:
解释一下:bkid在此处没有用到;isok列是用来判断消息是否已读,未读为0;
现在,来说一下步骤:(分前台和后台两部分)
在这篇随笔中我们首先来说一下前台页面是如何实现的:(李四登录)
用session存取一下lisi;便于后面从user表中取数据
1、布局页面代码以及读取数据代码:
