注册，激活邮件实践

本文参考十八哥的视频

数据库：

create table user(uid int primary key auto_increment,uname char(20) not null default ' ',email char(32) not null default ' ',pass char(32) not null default '',status tinyint not null default 0)engine myisam charset utf8;

create table activecode(cid int primary key auto_increment,uname char(20) not null default '',code char(16) not null default '',expire int not null default 0)engine myisam charset utf8;

php

conn.php:数据库连接

<?php

$conn=mysql_connect('localhost','root','root');

mysql_query('use tempemail',$conn);

mysql_query('set names utf8',$conn);

?>

01.php：模拟注册用户，创建激活码，发送激活码

 <?php

require('./conn.php');

require('./PHPMailer/class.phpmailer.php');

 $str='abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ123456';

 $uname=substr(str_shuffle(substr($str, 0,52)),0,8);//生成8位随机用户名

 $email='[email protected]';

//模拟注册

 $sql="insert into user(uname,email) values('$uname','$email')";

 mysql_query($sql,$conn);

//生成激活码

$code=substr(str_shuffle(substr($str, 0,52)),0,8);

$expire=time()+5*24*3600;

$sql="insert into activecode(uname,code,expire) values('$uname','$code','$expire')";

mysql_query($sql,$conn);

//发送激活邮件

$phpmailer= new PHPMailer();

//选用smtp

$phpmailer->IsSMTP();

$phpmailer->Host='smtp.163.com';

$phpmailer->SMTPAuth=true;

$phpmailer->Username='php0620';

$phpmailer->Password='pwd';

//可以发信了

$phpmailer->From='[email protected]';

$phpmailer->FromName='fromname';

$phpmailer->Subject=$uname.'欢迎注册';

$phpmailer->Body='请点击:http://localhost/02.php?code='.$code.' 进行激活';

//设置收件人

$phpmailer->AddAddress('[email protected]','first');

$phpmailer->AddCC('[email protected]','second');

//发信

echo $phpmailer->send()?'ok':'no';

 ?>

02.php

<?php

require('./conn.php');

$code=$_GET['code'];

if(strlen($code)!=8){

exit('激活码错误');

}

$sql="select * from activecode where code='$code'";

$rs=mysql_query($sql,$conn);

$row=mysql_fetch_assoc($rs);

if(empty($row)){

exit('激活码错误');

}

if(time()>$row['expire']){

exit('激活码过期');

}

//激活用户update

$sql="update user set status=1 where uname='$row[uname]'";

mysql_query($sql,$conn);

//作废激活码

$sql="update activecode set expire=0 where code='$code'";

mysql_query($sql,$conn);

?>
