老师，我这个运行只会闪一下静态页面

这里是封装函数
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | <?php/** * 数据库连接初始化 * @param $host * @param $username * @param $password * @param $dbName * @return bool|resource */function mysqlInit($host, $username, $password, $dbName){ $con = mysql_connect($host, $username,$password); if (!$con) { return false; } mysql_select_db($dbName); mysql_query($con,'set names utf8'); return $con;} |

您好，接收post方式的数据应该使用$_POST['name']。请注意$_POST大写，并且为[]。祝学习愉快！
<?php
//表单进行了提交处理
if(!empty($_post['username']))
{
include_once './lib/fun.php';
$username = trim($_post('username'));//mysql_real_escape_string()进行过滤，检测用户输入的是否NULL
$password = trim($_post('password'));
$repassword = trim($_post('repassword'));
//判断用户名不能为空
if(!$username){
echo "用户名不能为空";exit;
}
if(!$password){
echo "密码不能为空";exit;
}
if(!$repassword){
echo "确认密码不能为空";exit;
}
if($password !== $repassword){
echo "两次密码输入不一致";
exit;
}
//数据库操作
$con = mysqlInit('127.0.0.1','root','','dshang');
if(!$con)
{
echo "mysql_error()";
exit;
}
//验证用户名是否存在
$sql= "SELECT count('id') as total
FROM `dsuser` WHERE 'username' = '{$username}' ";
$obj = mysql_query($sql);
$result = mysql_fetch_assoc($obj);
var_dump($result); die;
if(isset($result['total'])&& $result['total']>0)
{
echo "用户名已存在，请重新输入";
}
//密码加密处理
$password= createpassword ($password);
unset($obj,$result,$sql);
//插入数据
$sql= "INSERT 'duser' ('username,password,create_time') values('{$username}','{$password}','{$_server['request_time']}') ";
$obj=mysql_query($sql);
if($obj)
{
$userid = mysql_insert_id();//插入成功的主键id
echo sprintf('恭喜您注册成功，用户名是:%s,用户id:%s',$username,$userid);
exit;
}
else
{
echo mysql_error(); exit;
}
}
