php 制作注册页面 中文无法存入sql 求解
用html制作了一个注册页面,提交到php页面,用post方法传送数据,但是文本框中输入了中文无法存入sql数据库中。求解,下面是关键代码:
======================================================================================
$userid=$_POST['userid'];
     $username=$_POST['username'];
      $userpwd=$_POST['userpwd'];
       $userage=$_POST['userage'];
        $usersex=$_POST['usersex'];
$conn=mysql_connect("localhost","root","");

mysql_select_db("newdb",$conn);

$sql="INSERT INTO usersinfo (userid,userpwd,username,userage,usersex)values('$userid','$userpwd','$username','$userage','$usersex')";
 mysql_query("set names 'utf8'");
$query=mysql_query($sql,$conn);
======================================================================================
userid usepwd userage 这三项为数字,可以存入sql数据库中,但是username usersex无法存入,
打开phpmyadmin 查看数据库,发现中文的那几栏都只有一个空格,存进去失败了。
不知道出现什么问题,添加了:
echo $userid."
";
echo $username."
";
echo $userpwd."
";
echo $userage."
";
echo $usersex."
";
发现可以正常输出任何变量,说明不是取值问题,是存入数据库的时候出问题了,我想是不是数据编码的问题..?

php 数据库
------解决方案--------------------
可否把数据库表结构贴出来看看是不是数据库字段类型的问题
------解决方案--------------------
一般是字符编码问题,可能你页面是GB2312数据库是UTF8,你用iconv("gbk","utf-8",$_POST['xx'])转下
------解决方案--------------------


发一个 Ecshop 给你看一下。

另外网页代码编码,也需要用跟数据库一致才行。
