求大神帮忙看看哪里出错了。
我想实现用户之间的通信,思想是建立一个消息表,然后把收件人用户名、发件人用户名、消息等放进去,然后谁想看发给自己的消息就去消息表中查找收件人是自己的记录。现在做到发消息这一块儿了,发完消息我发现数据库消息表中并没有记录,应该是没有正确插入表中,大神帮忙看看是哪里错了,我也是刚接触PHP的,以前上课学的东西都是基础的,运用到实践中总是出很多问题。
下面附上相关的代码(其中sqltable是用户表,sqltable2是消息表,user_name是用户表中存储用户名的,s_name是消息表中存储发件人的,r_name是消息表中收件人

config.php

<?php <br />//常规参数设置<br /><br />$servername="localhost";  //主机名<br />$sqlservername="root"; //mysql数据库用户名<br />$sqlserverpws="lmy"; //mysql数据库密码<br /><br />$sqlname="lmy"; //数据库名<br />$sqltable="user"; //username表名<br />$sqltable2="message";<br /><br />$admin_name="lmy";  //管理员用户名<br />$admin_pws="lmy";   //管理员密码<br />?>

------解决思路----------------------
哈哈,把分给我吧,已经远程协助解决。就是sql表里没有is_open字段而php又要插入is_open字段值,还有就是sql语句拼装问题
