PHP email sending verification function

Step 1: Create a database

Copy and paste the following database into a notepad, then create a new database in PHPMyAdmin and import the following data.

– Table structure `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 ;

–
– Export the data in the table `registered_members`
–
– ——————————————————–
–
– The structure of the table `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;

–
– Export the data in the table `temp_members_db`
–

Step 2: Establish a database connection

Please copy the following code into your text compiler and name it: 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");

?>

Step 3: Registration page
Please copy the following code into your text editor and name it: signup.php

Step 4: Insert data into the data and send by email

Please copy the code below Go to your text editor and name it: 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 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

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:wampwwwmailverificationsignup_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。
