本节内容：
php实现邮件发送、邮件验证功能。
第一步：建立数据库
在phpmyadmin创建一个新的数据库并导入下面数据。
复制代码 代码示例:
-- 表的结构 `registered_members`
--
CREATE TABLE `registered_members` (
`id` int(4) NOT NULL auto_increment,
`name` varchar(65) NOT NULL default '',
`email` varchar(65) NOT NULL default '',
`password` varchar(65) NOT NULL default '',
`country` varchar(65) NOT NULL default '',
PRIMARY KEY (`id`)
) ENGINE=
myisam DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
--
-- 导出表中的数据 `registered_members`
--
-- --------------------------------------------------------
--
-- 表的结构 `temp_members_db`
--
CREATE TABLE `temp_members_db` (
`confirm_code` varchar(65) NOT NULL default '',
`name` varchar(65) NOT NULL default '',
`email` varchar(65) NOT NULL default '',
`password` varchar(15) NOT NULL default '',
`country` varchar(65) NOT NULL default ''
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
--
-- 导出表中的数据 `temp_members_db`
--
第二步：建立数据库连接
config.php
复制代码 代码示例:
<?php
$host="
hostname"; // Host name
$username="Username"; //
mysql username
$password="Password"; // Mysql password
$db_name="DB name"; // Database name
//Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect to server");
mysql_select_db("$db_name")or die("cannot select DB");
?>;
第三步：注册页面
signup.php
复制代码 代码示例:
<table border="0" cellspacing="0" cellpadding="0" width="350" align="center">
<tbody>
<tr>
<td>
<form action="signup_ac.php" method="post">
<table border="0" cellspacing="4" cellpadding="0" width="100%">
<tbody>
<tr>
<td colspan="3"><strong>注册</strong></td>
</tr>
<tr>
<td width="76">用户名</td>
<td width="3"></td>
<td width="305"><input id="name" name="name" size="30" type="text" /></td>
</tr>
<tr>
<td>邮箱</td>
<td></td>
<td><input id="email" name="email" size="30" type="text" /></td>
</tr>
<tr>
<td>密码</td>
<td></td>
<td><input id="password" name="password" size="30" type="password" /></td>
</tr>
<tr>
<td>国家</td>
<td></td>
<td><input id="country" name="country" size="30" type="text" /></td>
</tr>
<tr>
<td></td>
<td></td>
<td>
<input name="Submit" type="submit" value="注册" />
<input name="Reset" type="reset" value="重设" />
</td>
</tr>
</tbody>
</table>
</form></td>
</tr>
</tbody>
</table>
第四步：数据插入到数据和邮件发送
signup_ac.php
复制代码 代码示例:
<?php
include('config.php');
// table name
$tbl_name=temp_members_db;
// Random confirmation code
$confirm_code=md5(uniqid(rand()));
// values sent from form
$name=$_POST['name'];
$email=$_POST['email'];
$country=$_POST['country'];
// Insert data into database
$sql="INSERT INTO $tbl_name(confirm_code, name, email, password, country)VALUES('$confirm_code', '$name', '$email', '$password', '$country')";
$result=mysql_query($sql);
// if suceesfully inserted data into database, send confirmation link to email
if($result){
// ---------------- SEND MAIL FORM ----------------
// send e-mail to ...
$to=$email;
// Your subject
$subject="Your confirmation link here";
// From
$header="from: your name <your email>";
// Your message
$message="Your Comfirmation link rn";
$message.="Click on this link to activate your account rn";
$message.="http://www.yourweb.com/confirmation.php?passkey=$confirm_code";
// send email
$sentmail = mail($to,$subject,$message,$header);
}
// if not found
else {
echo "Not found your email in our database";
}
// if your email succesfully sent
if($sentmail){
echo "Your Confirmation link Has Been Sent To Your Email Address.";
}
else {
echo "Cannot send Confirmation link to your e-mail address";
}
?>
第五步：验证
confirmation.php
复制代码 代码示例:
<?php
include('config.php');
// Passkey that got from link
$passkey=$_GET['passkey'];
$tbl_name1="temp_members_db";
// Retrieve data from table where row that match this passkey
$sql1="SELECT * FROM $tbl_name1 WHERE confirm_code ='$passkey'";
$result1=mysql_query($sql1);
// If successfully queried
if($result1){
// Count how many row has this passkey
$count=mysql_num_rows($result1);
// if found this passkey in our database, retrieve data from table "temp_members_db"
if($count==1){
$rows=mysql_fetch_array($result1);
$name=$rows['name'];
$email=$rows['email'];
$password=$rows['password'];
$country=$rows['country'];
$tbl_name2="registered_members";
// Insert data that retrieves from "temp_members_db" into table "registered_members"
$sql2="INSERT INTO $tbl_name2(name, email, password, country)VALUES('$name', '$email', '$password', '$country')";
$result2=mysql_query($sql2);
}
// if not found passkey, display message "Wrong Confirmation code"
else {
echo "Wrong Confirmation code";
}
// if successfully moved data from table"temp_members_db" to table "registered_members" displays message "Your account has been activated" and don't forget to delete confirmation code from table "temp_members_db"
if($result2){
echo "Your account has been activated";
// Delete information of this user from table "temp_members_db" that has this passkey
$sql3="DELETE FROM $tbl_name1 WHERE confirm_code = '$passkey'";
$result3=mysql_query($sql3);
}
}
?>
注意：
如果没有邮箱服务器的，会出现如下面提示之类的东西：
Warning: mail() [function.mail]: Failed to connect to mailserver at “localhost” port 25, verify your “SMTP” and “smtp_port” setting in php.ini or use ini_set() in E:wampwwwmailverificationsignup_ac.php on line 39
Cannot send Confirmation link to your e-mail address
这说明你的数据已经被写进数据库了。
可以用以下方法去通过验证：
先复制这个URL到你的浏览器：http://www.你的网站.com/confirmation.php?passkey=
然后到数据库中，把confirm_code复制粘贴在passkey=后面，并回车，会出现提示的：Your account has been activated!
邮件验证系统就完成了。
