这是一款利用php 与mysql数据库实现的用户注册与登录代码,功能也是比较简单实用的用户注册程序,同时也加了用户登录时验证码程序,这样做就安全了很多,代码如下:
- <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">
- <html xmlns="http://www.111cn.net/1999/xhtml">
- <head>
- <meta http-equiv="content-type" content="text/html; charset=gb2312" />
- <title>在后台增加用户</title>
- </head>
-
- <body>
-
- <?php
- require_once("config.php");
- if(isset($_post["submit2"])){
- mysql_select_db('a0807000225');
- $author=$_session["user_name"];
- define(all_ps,"jinquan");
- echo $username=$_post["username"];
- echo $password=md5($password=$_post["password"].all_ps);
- echo "</br>";
- if($username){
- if($password){
- $str = "insert into `dx_user_list` ( `uid` , `m_id` , `username` , `password` ) values (ascii( null ) , '1', '$username', '$password');";
- $rs=mysql_query($str,$conn);
- mysql_close($conn);
- }
- if($rs){
- echo"<script>alert('新增成功');location.href='yonghuzc.php'</script>";
- }else{
- echo"<script>alert('新增失败');location.href=''yonghuzc.php'</script>";
- }
- }
- }
-
-
- ?>
