PHP会员找回密码功能实现实例介绍

如果你做的网站有会员系统那必须就自动找回密码功能了,也就是忘记密码功能,如果用户忘记了密码可以通过邮箱或手机号直接找回密码,下面我来介绍邮箱找回密码方法。
设置思路
1、用户注册时需要提供一个E-MAIL邮箱,目的就是用该邮箱找回密码。
2、当用户忘记密码或用户名时,点击登录页面的“找回密码”超链接,打开表单,并输入注册用的E-MAIL邮箱,提交。
3、系统通过该邮箱,从数据库中查找到该用户信息,并更新该用户的密码为一个临时密码(比如:12345678)。
4、系统借助Jmail功能把该用户的信息发送到该用户的邮箱中(内容包括:用户名、临时密码、提醒用户及时修改临时密码的提示语)。
5、用户用临时密码即可登录。
HTML,我们在找回密码的页面上放置一个要求用户输入注册时所用的邮箱,然后提交前台js来处理交互,代码如下:
- <p><strong>输入您注册的电子邮箱,找回密码:</strong></p>
 - <p><input type="text" class="input" name="email" id="email"><span id="chkmsg"></span></p>
 - <p><input type="button" class="btn" id="sub_btn" value="提 交"></p>
 
jQuery,当用户输入完邮箱并点击提交后,jQuery先验证邮箱格式是否正确,如果正确则通过向后台sendmail.php发送Ajax请求,sendmail.php负责验证邮箱是否存在和发送邮件,并会返回相应的处理结果给前台页面,请看jQuery代码:
- $(function(){
 - $("#sub_btn").click(function(){
 - var email = $("#email").val();
 - var preg = /^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*/; //匹配Email
 - if(email=='' || !preg.test(email)){
 - $("#chkmsg").html("请填写正确的邮箱!");
 - }else{
 - $("#sub_btn").attr("disabled","disabled").val('提交中..').css("cursor","default");
 - $.post("sendmail.php",{mail:email},function(msg){
 - if(msg=="noreg"){
 - $("#chkmsg").html("该邮箱尚未注册!");
 - $("#sub_btn").removeAttr("disabled").val('提 交').css("cursor","pointer");
 - }else{
 - $(".demo").html("<h3>"+msg+"</h3>");
 - }
 - });
 - }
 - });
 - })
 
以上使用的jQuery代码很方便简洁的完成了前端交互操作,如果您有一定的jQuery基础,那上面的代码一目了然,不多解释。
当然别忘了在页面中加载jQuery库文件,有的同学经常问我说从www.phpfensi.com下载了demo怎么用不了,那80%是jquery或者其他文件加载路径错了导致没加载必要的文件。
PHP:sendmail.php需要验证Email是否存在系统用户表中,如果有,则读取用户信息,将用户id、用户名和密码惊醒md5加密生成一个特别的字符串作为找回密码的验证码,然后构造URL,同时我们为了控制URL链接的时效性,将记录用户提交找回密码动作的操作时间,最后调用邮件发送类发送邮件到用户邮箱,发送邮件类smtp.class.php已经打包好,请下载,代码如下:
- include_once("connect.php");//连接数据库
 - $email = stripslashes(trim($_POST['mail']));
 - $sql = "select id,username,password from `t_user` where `email`='$email'";
 - $query = mysql_query($sql);
 - $num = mysql_num_rows($query);
 - if($num==0){//该邮箱尚未注册!
 - echo 'noreg';
 - exit;
 - }else{
 - $row = mysql_fetch_array($query);
 - $getpasstime = time();
 - $uid = $row['id'];
 - $token = md5($uid.$row['username'].$row['password']);//组合验证码
 - $url = "/demo/resetpass/reset.php?email=".$email."
 - &token=".$token;//构造URL
 - $time = date('Y-m-d H:i');
 - $result = sendmail($time,$email,$url);
 - if($result==1){//邮件发送成功
 - $msg = '系统已向您的邮箱发送了一封邮件<br/>请登录到您的邮箱及时重置您的密码!';
 - //更新数据发送时间
 - mysql_query("update `t_user` set `getpasstime`='$getpasstime' where id='$uid '");
 - }else{
 - $msg = $result;
 - }
 - echo $msg;
 - }
 - //发送邮件
 - function sendmail($time,$email,$url){
 - include_once("smtp.class.php");
 - $smtpserver = ""; //SMTP服务器,如smtp.163.com
 - $smtpserverport = 25; //SMTP服务器端口
 - $smtpusermail = ""; //SMTP服务器的用户邮箱
 - $smtpuser = ""; //SMTP服务器的用户帐号
 - $smtppass = ""; //SMTP服务器的用户密码
 - $smtp = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass);
 - //这里面的一个true是表示使用身份验证,否则不使用身份验证.
 - $emailtype = "HTML"; //信件类型,文本:text;网页:HTML
 - $smtpemailto = $email;
 - $smtpemailfrom = $smtpusermail;
 - $emailsubject = "www.111cn.net - 找回密码";
 - $emailbody = "亲爱的".$email.":<br/>您在".$time."提交了找回密码请求。请点击下面的链接重置密码
 - (按钮24小时内有效)。<br/><a href='".$url."'target='_blank'>".$url."</a>";
 - $rs = $smtp->sendmail($smtpemailto, $smtpemailfrom, $emailsubject, $emailbody, $emailtype);
 - return $rs;
 - }
 
好了,这个时候你的邮箱将会收到一封来自helloweba的密码找回邮件,邮件内容中有一个URL链接,点击该链接到www.phpfensi.com的reset.php来验证邮箱,代码如下:
- include_once("connect.php");//连接数据库
 - $token = stripslashes(trim($_GET['token']));
 - $email = stripslashes(trim($_GET['email']));
 - $sql = "select * from `t_user` where email='$email'";
 - $query = mysql_query($sql);
 - $row = mysql_fetch_array($query);
 - if($row){
 - $mt = md5($row['id'].$row['username'].$row['password']);
 - if($mt==$token){
 - if(time()-$row['getpasstime']>24*60*60){
 - $msg = '该链接已过期!';
 - }else{
 - //重置密码...
 - $msg = '请重新设置密码,显示重置密码表单,<br/>这里只是演示,略过。';
 - }
 - }else{
 - $msg = '无效的链接';
 - }
 - }else{
 - $msg = '错误的链接!';
 - }
 - echo $msg;
 
reset.php首先接受参数email和token,然后根据email查询数据表t_user中是否存在该Email,如果存在则获取该用户的信息,并且和sendmail.php中的token组合方式一样构建token值,然后与url传过来的token进行对比,如果当前时间与发送邮件时的时间相差超过24小时的,则提示“该链接已过期!”,反之,则说明链接有效,并且调转到重置密码页面,最后就是用户自己设置新密码了。
小结:通过注册邮箱验证与本文邮件找回密码,我们知道发送邮件在网站开发中的应用以及它的重要性,当然,现在也流行短信验证应用,这个需要相关的短信接口对接就可以了。
最后,附上数据表t_user结构,代码如下:
- CREATE TABLE `t_user` (
 - `id` int(11) NOT NULL auto_increment,
 - `username` varchar(30) NOT NULL,
 - `password` varchar(32) NOT NULL,
 - `email` varchar(50) NOT NULL,
 - `getpasstime` int(10) NOT NULL,
 - PRIMARY KEY (`id`)
 - ) ENGINE=MyISAM DEFAULT CHARSET=utf8;
