PHP用户注册基本处理
1、本文代码能够完成的功能有:用户注册,用户注册项检查,用户名重复检测(该功能要重新设计),首先要在mysql数据库test中创建users表格
2、代码
index.html
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"><title>注册页面</title><script language="javascript">function check(){ if(myform.realname.value == "") { alert("请输入真实姓名!"); myform.realname.focus(); return false; } if(myform.pwd.value == "") { alert("请输入密码!"); myform.pwd.focus(); return false; } if(myform.cpwd.value == "") { alert("请输入确认密码!"); myform.cpwd.focus(); return false; } if(myform.pwd.value.length<6) { myform.pwd.value=""; myform.cpwd.value=""; alert("密码少于6位,请重新输入!"); return false; } if(myform.pwd.value != myform.cpwd.value) { alert("确认密码与原密码不同!"); myform.pwd.value=""; myform.cpwd.value=""; return false; } if(myform.email.value == "") { alert("您没有输入email地址!"); myform.email.focus(); return false; } var i=myform.email.value.indexOf("@"); var j=myform.email.value.indexOf("."); if(i<0 || j<0 || j<i) { alert("您输入的email地址格式有误!"); myform.email.value=""; myform.email.focus(); return false; }}function checkuser(name){ if(name == "") { alert("用户名不能为空!"); myform.username.focus(); return false; } else { window.open("http://localhost/Workspace/FirstPHP/checkuser.php?param1="+name,"checkuser","width=200,height=100"); }}</script>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"><?php include("connect_mysql.php"); $sql="insert into users(用户名,真实姓名,密码,性别,联系电话,QQ号码,Email,个人主页,家庭住址) values('". $_POST['username']."','".$_POST['realname']."','".$_POST['pwd']."','".$_POST['sex']."','".$_POST['tel']. "','".$_POST['qq']."','".$_POST['email']."','".$_POST['homepage']."','".$_POST['addr']."')"; $res=mysql_query($sql); if(!empty($res)) { echo "<script>alert('注册成功!');window.location='index.html';"; } else { echo "<script>alert('注册失败!');window.location='index.html';</script>"; }?>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"><?php include "connect_mysql.php"; $name=$_GET['param1']; $res=mysql_query("select * from users where 用户名='$name'"); $re=mysql_fetch_array($res); if(!empty($re)) { echo "<font color='red'>用户名 $name 已经存在!"; } else { echo "<font color="'green'">用户名 $name 通过检测 !</font>"; }?>
<?php $con=mysql_connect("localhost","root","08246298"); mysql_select_db("test",$con);?>
