PHP用户注册邮箱验证激活帐号示例,获取表单数

作者: 计算机网络  发布:2019-09-26

这是一篇基础的php教程入门教程,我们要告诉你如何利用php的相关函数来获取表单数据,在php提供了post,get,request三种方法来获取数据,我们最常用的就是$_POST,$_GET方法了,看
$_REQUEST 变量
PHP 的 $_REQUEST 变量包含了 $_GET, $_POST 以及 $_COOKIE 的内容。

功能需求

PHP 的 $_REQUEST 变量可用来取得通过 GET 和 POST 方法发送的表单数据的结果。

PHP程序开发,用户在网站注册,需要用户通过邮件链接激活帐号,当用户注册后(用户信息写入数据库),没有登录邮箱激活帐号,规定24小时后自动删除没有激活帐号的用户信息,实现激活链接过期后,用户还可以使用该信息在网站注册

实例

准备数据表

 

用户信息表中字段Email很重要,它可以用来验证用户、找回密码、甚至对网站方来说可以用来收集用户信息进行Email营销,以下是用户信息表t_user的表结构:

<html>
<head>
<title>An HTML Form that Calls Itself</title>
</head>
<body>
<div>
<?php
if ( ! empty( $_POST['guess'] ) ) {
    print "last guess: ".$_POST['guess'];
}
?>
<form method="post" action="<?php print $_SERVER['PHP_SELF']?>">
<p>
Type your guess here: <input type="text" name="guess" />
</p>
</form>
</div>
</body>
</html>

 代码如下

由于表的提供大量数据时我们尽量用post来获取,更复杂的实例二
 
实例二

CREATE TABLE IF NOT EXISTS `t_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(30) NOT NULL COMMENT '用户名',
  `password` varchar(32) NOT NULL COMMENT '密码',
  `email` varchar(30) NOT NULL COMMENT '邮箱',
  `token` varchar(50) NOT NULL COMMENT '帐号激活码',
  `token_exptime` int(10) NOT NULL COMMENT '激活码有效期',
  `status` tinyint(1) NOT NULL DEFAULT '0' COMMENT '状态,0-未激活,1-已激活',
  `regtime` int(10) NOT NULL COMMENT '注册时间',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;

<?php

$self = $_SERVER['PHP_SELF'];
$username = $_POST['username'];
$useraddr = $_POST['useraddr'];
$comments = $_POST['comments'];
$sent = $_POST['sent'];

$form ="<form action="$self" method="post">";
$form.="Name:<input type="text" name="username"";
$form.=" size="30" value="$username" >";
$form.="Email:<input type="text" name="useraddr"";
$form.=" size="30" value="$useraddr">";
$form.="Comments:<textarea name="comments" >";
$form.="$comments</textarea><br/>";
$form.="<input type="submit" name="sent" value="Send Form">";
$form.="</form>";

if($sent)
{
  $valid=true;

  if( !$username )
  { $errmsg.="Enter your name...<br />"; $valid = false; }

  if( !$useraddr )
  { $errmsg .="Enter your email address...<br />"; $valid = false; }

  if( !$comments )
  { $errmsg.="Enter your comments...<br />"; $valid = false; }

  $useraddr = trim($useraddr);
  $_name = "/^[-!#$%&'*+./0-9=?A-Z^_'{|}~]+";
  $_host = "([-0-9A-Z]+.)+";
  $_tlds = "([0-9A-Z]){2,4}$/i";
  if( preg_match( $_name."@".$_host .$_tlds,$useraddr ) )
  {
    $errmsg.="Email address has incorrect format!<br />";
    $valid=false;
  }
}

if($valid != true)
{
  echo( $errmsg.$form );
}
else
{
  $to = "php@h.com";

  $re = "Feedback from $username";

  $msg = $comments;

  $headers  = "MIME-Version: 1.0rn";
  $headers .= "Content-type: text/html;";  
  $headers .= "charset="iso-8859-1"rn";

  $headers .= "From: $useraddr rn";

  if(mail($to,$re,$msg, $headers))
  { echo("Your comments have been sent - thanks $username");}

}
?>

HTML

上面可对用户提交的数据进行一些相关处理了。上只讲了$_POST

在页面中放置一个注册表单,用户可以输入注册信息,包括用户名、密码和邮箱。

$_POST 变量
$_POST 变量是一个数组,内容是由 HTTP POST 方法发送的变量名称和值。

 代码如下

$_POST 变量用于收集来自 method="post" 的表单中的值。从带有 POST 方法的表单发送的信息,对任何人都是不可见的(不会显示在浏览器的地址栏),并且对发送信息的量也没有限制。

<form id="reg" action="register.php" method="post">
    <p>用户名:<input type="text" class="input" name="username" id="user"></p>
    <p>密 码:<input type="password" class="input" name="password" id="pass"></p>
    <p>E-mail:<input type="text" class="input" name="email" id="email"></p>
    <p><input type="submit" class="btn" value="提交注册"></p>
</form>

对于用户的输入要进行必要的前端验证,关于表单验证功能,建议您参考本站文章:实例讲解表单验证插件Validation的应用,本文对前端验证代码略过,另外其实页面中还应该有个要求用户重复输入密码的输入框,一时偷懒就此略过。
register.php

用户将注册信息提交到register.php进行处理。register.php需要完成写入数据和发送邮件两大功能。

首先包含必要的两个文件,connect.php和smtp.class.php,这两个文件在外面提供的下载包里有,欢迎下载。

 代码如下

include_once("connect.php");//连接数据库
include_once("smtp.class.php");//邮件发送类

然后我们要过滤用户提交的信息,并验证用户名是否存在(前端也可以验证)。

$username = stripslashes(trim($_POST['username']));
$query = mysql_query("select id from t_user where username='$username'");
$num = mysql_num_rows($query);
if($num==1){
    echo '用户名已存在,请换个其他的用户名';
    exit;
}

接着我们将用户密码加密,构造激活识别码:

 代码如下

$password = md5(trim($_POST['password'])); //加密密码
$email = trim($_POST['email']); //邮箱
$regtime = time();
 
$token = md5($username.$password.$regtime); //创建用于激活识别码
$token_exptime = time()+60*60*24;//过期时间为24小时后
 
$sql = "insert into `t_user` (`username`,`password`,`email`,`token`,`token_exptime`,`regtime`) 
values ('$username','$password','$email','$token','$token_exptime','$regtime')";
 
mysql_query($sql);

上述代码中,$token即构造好的激活识别码,它是由用户名、密码和当前时间组成并md5加密得来的。$token_exptime用于设置激活链接URL的过期时间,用户在这个时间段内可以激活帐号,本例设置的是24小时内激活有效。最后将这些字段插入到数据表t_user中。

当数据插入成功后,调用邮件发送类将激活信息发送给用户注册的邮箱,注意将构造好的激活识别码组成一个完整的URL作为用户点击时的激活链接,以下是详细代码:

 代码如下

if(mysql_insert_id()){
    $smtpserver = ""; //SMTP服务器,如:smtp.163.com
    $smtpserverport = 25; //SMTP服务器端口,一般为25
    $smtpusermail = ""; //SMTP服务器的用户邮箱,如xxx@163.com
    $smtpuser = ""; //SMTP服务器的用户帐号xxx@163.com
    $smtppass = ""; //SMTP服务器的用户密码
    $smtp = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass); //实例化邮件类
    $emailtype = "HTML"; //信件类型,文本:text;网页:HTML
    $smtpemailto = $email; //接收邮件方,本例为注册用户的Email
    $smtpemailfrom = $smtpusermail; //发送邮件方,如xxx@163.com
    $emailsubject = "用户帐号激活";//邮件标题
    //邮件主体内容
    $emailbody = "亲爱的".$username.":<br/>感谢您在我站注册了新帐号。<br/>请点击链接激活您的帐号。<br/>
    <a href='/demo/register/active.php?verify=".$token."' target=
'_blank'>/demo/register/active.php?verify=".$token."</a><br/>
    如果以上链接无法点击,请将它复制到你的浏览器地址栏中进入访问,该链接24小时内有效。";
    //发送邮件
    $rs = $smtp->sendmail($smtpemailto, $smtpemailfrom, $emailsubject, $emailbody, $emailtype);
    if($rs==1){
        $msg = '恭喜您,注册成功!<br/>请登录到您的邮箱及时激活您的帐号!';    
    }else{
        $msg = $rs;    
    }
}
echo $msg;

还有一个相当好用且强大的邮件发送类分享个大家:使用PHPMailer发送带附件并支持HTML内容的邮件,直接可以用哦。
active.php

如果不出意外,您注册帐号时填写的Email将收到一封helloweba发送的邮件,这个时候您直接点击激活链接,交由active.php处理。

active.php接收提交的链接信息,获取参数verify的值,即激活识别码。将它与数据表中的用户信息进行查询对比,如果有相应的数据集,判断是否过期,如果在有效期内则将对应的用户表中字段status设置1,即已激活,这样就完成了激活功能。

 代码如下

include_once("connect.php");//连接数据库
 
$verify = stripslashes(trim($_GET['verify']));
$nowtime = time();
 
$query = mysql_query("select id,token_exptime from t_user where status='0' and 
`token`='$verify'");
$row = mysql_fetch_array($query);
if($row){
    if($nowtime>$row['token_exptime']){ //24hour
        $msg = '您的激活有效期已过,请登录您的帐号重新发送激活邮件.';
    }else{
        mysql_query("update t_user set status=1 where id=".$row['id']);
        if(mysql_affected_rows($link)!=1) die(0);
        $msg = '激活成功!';
    }
}else{
    $msg = 'error.';    
}
echo $msg;

激活成功后,发现token字段并没有用处了,您可以清空。接下来我们会讲解用户找回密码的功能,也要用到邮箱验证,敬请关注。

最后附上邮箱smtp.class.php发送类

 代码如下

<?php
