PHP邮件发送验证功能
第一步：建立数据库
把下面数据库复制粘贴在一个记事本，然后在PHPMyAdmin创建一个新的数据库并导入下面数据。
– 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
请把下面代码复制到你的文本编编译器里面，并命名：config.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
请把下面代码复制到你的文本编辑器里面，并命名：signup.php
第四步：数据插入到数据和邮件发送
请把下面代码复制到你的文本编辑器里面，并命名：signup_ac.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 message
$message=”Your Comfirmation link \r\n”;
$message.=”Click on this link to activate your account \r\n”;
$message.=”http://www.yourweb.com/confirmation.php?passkey=$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
请把下面代码复制到你的文本编辑器里面，并命名：confirmation.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() inE:\wamp\www\mailverification\signup_ac.php?on line?39
Cannot send Confirmation link to your e-mail address
不用慌，这说明你的数据已经被写进数据库了。
你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=
然后到你的数据库里面把confirm_code复制粘贴在passkey=后面，并回车，会出现提示的：Your account has been activated!
恭喜你了!你的邮件验证系统就完成了！如果有什么问题的，欢迎随时留言，回以最快的速度解决你的问题。由于时间关系，英文就不做翻译了。
