邮箱验证功能的实现

创建时间:2018-01-07 投稿人: 浏览次数:644

采用PHPMailer库实现了邮箱验证功能,下面请看代码

首先是发送邮件的函数

<?php

include "class.phpmailer.php";
include "class.smtp.php";
function send_mail( $sendto_email, $subject, $body,$rec_name){   
        $mail = new PHPMailer();   
        $mail->isSMTP();                  // send via SMTP   
        $mail->Host = "mail.ustc.edu.cn";   // SMTP servers  
        $mail->SMTPSecure = "ssl";
        $mail->Port =465;    
        $mail->SMTPAuth = true;           // turn on SMTP authentication   
        $mail->Username = "xxxx";     // SMTP username  注意:普通邮件认证不需要加 @域名   
        $mail->Password = "xxxx" ; // SMTP password   
        $mail->setFrom("xxxx", "学海灯塔");
        $mail->CharSet = "UTF-8";   // 这里指定字符集!     
        $mail->addAddress($sendto_email,$rec_name);  // 收件人邮箱和姓名   
        $mail->IsHTML(true);  // send as HTML   
        $mail->Subject = $subject;   
        $mail->Body =$body;                                                                         
        $mail->Form= "xxxx";
        $mail->Helo= "xxxx";
        $mail->Send();  
   ?> 

这是一个名为send_mail的函数,用到了class.phpmailer.php与class.smtp.php两个库文件(文章末尾附上)

接着是注册表单

<form name="register" action="register_handle.php" method="post"  class="login">
                <p class="lead">注册用户</p>
                <div class="form-group">
                    <input type="text" autocomplete="off" class="required form-control" placeholder="用户名 *" name="username" value="<?php if(isset($_COOKIE["tuname"])){echo $_COOKIE["tuname"];}?>">
                </div>
                <div class="form-group">
                    <input type="password" class="required form-control" placeholder="密码 *" name="password" value="<?php if(isset($_COOKIE["password"])){echo $_COOKIE["password"];}?>">
                </div>
                <div class="form-group">
                    <input type="password" class="required form-control" placeholder="确认密码 *" name="ConformPassword" value="<?php if(isset($_COOKIE["password"])){echo $_COOKIE["password"];}?>">
                </div>
                <div class="form-group">
                    <input type="text" autocomplete="off" class="required form-control" placeholder="科大邮箱 *" name="email" value="<?php if(isset($_COOKIE["email"])){echo $_COOKIE["email"];}?>">
                    <input type="submit" name="verification" value="发送验证码" class="course-submit" onclick="return check();">
                </div>
                <div class="form-group">
                    <input type="text" autocomplete="off" class="required form-control" placeholder="邮箱验证码(登录邮箱查询) *" name="conformemail" value="">
                </div>
                <div class="form-group">
                    <input type="submit" class="btn btn-primary btn-lg1 btn-block" name="submit" value="注册"  >
                </div>
            </form>

注册信息处理

<?php 
include "mail.php";
function createRandomStr($length){ 
    $str = "0123456789abcdefghijklmnopqrstuvwxyz";
    $strlen = 0; 
    while($length > $strlen){ 
    $str .= $str; 
    $strlen++; 
    } 
    $str = str_shuffle($str); 
    return substr($str,0,$length); 
    } 

    

$very=createRandomStr(6);
$username=$_POST["username"];
$email=$_POST["email"];
$ac=0;

$link = mysqli_connect("localhost","users","666","users");

if(isset($_POST["verification"])){

    $password=$_POST["password"];
  
    if(mysqli_query($link,"insert into users (username,password,mail,verycode,active) values("$username","$password","$email","$very","$ac")"))
    {  
       send_mail($email, "欢迎使用学海灯塔!", "这是您的验证码:$very",$username); 
       setcookie("password",$password,time()+7200);
       setcookie("tuname",$username,time()+7200);
       setcookie("email",$email,time()+7200);
       echo "<script>alert("验证码已发送");window.location.href= "register.php";</script>";
    }else {
        echo "<script>alert("抱歉,该用户名已注册");window.location.href= "register.php";</script>";
    }
}

if(isset($_POST["submit"])){
   
    $veryin=$_POST["conformemail"];
    $query=mysqli_query($link,"SELECT verycode FROM users WHERE username = "$username"");
    $row = mysqli_fetch_array($query);

    if($row["verycode"]==$veryin){
        setcookie("uname",$username,time()+7200);
        setcookie("tuname","",time()-1);
        setcookie("password","",time()-1);
        setcookie("email","",time()-1);
        session_start();
        $_SESSION[$username]=1;
        mysqli_query($link,"UPDATE users set active=1 WHERE username = "$username"");
       echo "<script>alert("验证成功");window.location= "index.php";</script>";
    }else {
        echo "<script>alert("验证失败");history.go(-1)</script>";
    }
}

?>

其中createRandomStr用于生成随机验证码,接着调用send_mail进行发送。在服务器端的数据库中设置一个名为active的字段,当用户提交表单后进行验证码的比较,若正确则将其置为1,表示账号激活成功

附上两个库文件:
