PHP会员找回暗码功效的简略完成

设置思绪

1、用户注册时须要供给一个E-MAIL邮箱，目标便是用该邮箱找回暗码。

2、当用户健忘暗码或用户名时，点击登录页面的“找回暗码”超链接，翻开表单，并输出注册用的E-MAIL邮箱，提交。

3、体系经由进程该邮箱，从数据库中查找到该用户信息，并更新该用户的暗码为一个姑且暗码（比方：12345678）。

4、体系借助Jmail功效把该用户的信息发送到该用户的邮箱中（内容包含：用户名、姑且暗码、提醒用户实时点窜姑且暗码的提醒语）。

5、用户用姑且暗码便可登录。

HTML

咱们在找回暗码的页面上安排一个请求用户输出注册时所用的邮箱，而后提交前台js来处置交互。

代码以下

<p><strong>输出您注册的电子邮箱，找回暗码：</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

当用户输出完邮箱并点击提交后，jQuery先考证邮箱格局是不是准确，若是准确则经由进程向背景sendmail.php发送Ajax请求，sendmail.php担任考证邮箱是不是存在和发送邮件，并会前往呼应的处置成果给前台页面，请看jQuery代码：

代码以下

$(function(){ 
$("#sub_btn").click(function(){ 
var email = $("#email").val(); 
var preg = /^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*/; //婚配Email 
if(email=="" || !preg.test(email)){ 
$("#chkmsg").html("请填写准确的邮箱！"); 
}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("该邮箱还没有注册！"); 
$("#sub_btn").removeAttr("disabled").val("提 交").css("cursor","pointer"); 
}else{ 
$(".demo").html("<h3>"+msg+"</h3>"); 
} 
}); 
} 
}); 
})

以上利用的jQuery代码很便利简练的完成了前端交互操纵，若是您有必然的jQuery根本，那上面的代码一目明了，未几诠释。

固然别忘了在页面中加载jQuery库文件，有的同窗常常问我说从网高低载了demo怎样用不了，那80%是jquery或其余文件加载途径错了致使没加载须要的文件。

PHP

sendmail.php须要考证Email是不是存在体系用户表中，若是有，则读取用户信息，将用户id、用户名和暗码惊醒md5加密天生一个出格的字符串作为找回暗码的考证码，而后机关URL。同时咱们为了节制URL链接的时效性，将记实用户提交找回暗码举措的操纵时辰，最初挪用邮件发送类发送邮件到用户邮箱，发送邮件类smtp.class.php已打包好，请下载。

代码以下

include_once("connect.php");//毗连数据库 

$email = stripslashes(trim($_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){//该邮箱还没有注册！ 
echo "noreg"; 
exit; 
}else{ 
$row = mysql_fetch_array($query); 
$getpasstime = time(); 
$uid = $row["id"]; 
$token = md5($uid.$row["username"].$row["password"]);//组合考证码 
$url = "/demo/resetpass/reset.php?email=".$email." 
&token=".$token;//机关URL 
$time = date("Y-m-d H:i"); 
$result = sendmail($time,$email,$url); 
if($result==1){//邮件发送胜利 
$msg = "体系已向您的邮箱发送了一封邮件<br/>请登录到您的邮箱实时重置您的暗码！"; 
//更新数据发送时辰 
mysql_query("update `t_user` set `getpasstime`="$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办事器，如smtp.163.com 
$smtpserverport = 25; //SMTP办事器端口 
$smtpusermail = ""; //SMTP办事器的用户邮箱 
$smtpuser = ""; //SMTP办事器的用户帐号 
$smtppass = ""; //SMTP办事器的用户暗码 
$smtp = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass); 
//这外面的一个true是表现利用身份考证,不然不利用身份考证. 
$emailtype = "HTML"; //函件范例，文本:text；网页：HTML 
$smtpemailto = $email; 
$smtpemailfrom = $smtpusermail; 
$emailsubject = "www.taishanly.com - 找回暗码"; 
$emailbody = "敬爱的".$email."：<br/>您在".$time."提交了找回暗码请求。请点击上面的链接重置暗码 
（按钮24小时内有用）。<br/><a href="".$url.""target="_blank">".$url."</a>"; 
$rs = $smtp->sendmail($smtpemailto, $smtpemailfrom, $emailsubject, $emailbody, $emailtype); 

return $rs; 
}

好了，这个时辰你的邮箱将会收到一封来自helloweba的暗码找回邮件，邮件内容中有一个URL链接，点击该链接到reset.php来考证邮箱。

代码以下

include_once("connect.php");//毗连数据库 

$token = stripslashes(trim($_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 = "该链接已过时！"; 
}else{ 
//重置暗码... 
$msg = "请从头设置暗码，显现重置暗码表单，<br/>这里只是演示，略过。"; 
} 
}else{ 
$msg = "有用的链接"; 
} 
}else{ 
$msg = "毛病的链接！"; 
} 
echo $msg;

 reset.php起首接管参数email和token，而后按照email查问数据表t_user中是不是存在该Email，若是存在则获得该用户的信息，并且和sendmail.php中的token组合体例一样构建token值，而后与url传过去的token停止对照，若是以后时辰与发送邮件时的时辰相差跨越24小时的，则提醒“该链接已过时！”，反之，则申明链接有用，并且调转到重置暗码页面，最初便是用户本身设置新暗码了。

小结：经由进程注册邮箱考证与本文邮件找回暗码，咱们晓得发送邮件在网站开辟中的利用和它的主要性，固然，此刻也风行短信考证利用，这个须要相干的短信接口对接就能够了。

最初，附上数据表t_user布局：

代码以下

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;
