<center>

<?php

session_start();

$code=rand(22222,99999);

$_SESSION["code"]=$code;

$username=$_POST['username'];

$firstname=$_POST['firstname'];

$lastname=$_POST['lastname'];

$_SESSION["username"]=$username;

$_SESSION["firstname"]=$firstname;

$_SESSION["lastname"]=$lastname;

require 'PHPMailer-master/PHPMailerAutoload.php';



$mail = new PHPMailer();



  //Enable SMTP debugging.

  $mail->SMTPDebug = 0;

  //Set PHPMailer to use SMTP.

  $mail->isSMTP();

  //Set SMTP host name

  $mail->Host = "smtp.gmail.com";

  $mail->SMTPOptions = array(

                    'ssl' => array(

                        'verify_peer' => false,

                        'verify_peer_name' => false,

                        'allow_self_signed' => true

                    )

                );

  //Set this to true if SMTP host requires authentication to send email

  $mail->SMTPAuth = TRUE;

  //Provide username and password

  $mail->Username = "yourgmailidhere@gmail.com";

  $mail->Password = "yourgmailpassword";

  //If SMTP requires TLS encryption then set it

  $mail->SMTPSecure = "false";

  $mail->Port = 587;

  //Set TCP port to connect to



  $mail->From = "bhupenderkashyap122@gmail.com";

  $mail->FromName = "jignesh";



  $mail->addAddress($_POST["username"]);



  $mail->isHTML(true);

$mail->addAttachment('lop.jpg', 'lop1.jpg'); //set new name





  $mail->Subject = "test mail";

  $mail->Body = "<i>this is your password:</i>".$code;

  $mail->AltBody = "This is the plain text version of the email content";

  if(!$mail->send())

  {

   echo "Mailer Error: " . $mail->ErrorInfo;

  }

  else

  {

   echo "<h1>OTP has been send succesfully in Your email Id please checkout </h1>";



   ?>

  

   <form action="mail2.php" method="post">



<input name="captcha" type="text">





<input type="submit" name="submit" value="submit">

</form>

  

<?php





  }

  ?>









</center>






Yanha mail.php file me apko sirf apna gmail id ka username and password enter karna hai agar aap is script ko localhost par run karwa rahe ho.,mail.php file  me hamne rand function and php mailer library ka use kiya hai.yanha rand function random otp code generate karega  aur fir phpmailer library function ki madad se generate  hua random otp user ki email id par jayega..






  mail2.php

<center>

<br>

<br>

<br>

<br>

<br>





<?php

session_start();

$code="";


if(isset($_POST["captcha"])&&$_POST["captcha"]!=""&&$_SESSION["code"]==$_POST["captcha"])

{

echo $captcha=$_POST['captcha'];

echo "<br>";

echo "Correct Code Entered";



include 'insert.php';







session_destroy();

//Do you stuff

}

else

{

echo "Wrong Code Entered Try Again";







?>









<form action="mail2.php" method="post">



<input name="captcha" type="text">



<input type="submit" name="submit" value="submit">

</form>

















<?php } ?>



<a href="index2.php">Index</a>

</center>

<center>

</center>

mail2.php  file validate karegi ki user dawara enter kiya gya otp ,and userki email id par gya otp code same hai ya nhi,ye work yanha ham session ki madad se karege.





insert.php

<?php





$conn=mysqli_connect("localhost","root","","google");

//enter your database detail Here



if(isset($_SESSION['username'])) {

  echo "Your session is running " . $_SESSION['username'];



$username=$_SESSION['username'];

$firstname=$_SESSION['firstname'];

$lastname=$_SESSION['lastname'];

$sql = "INSERT INTO otp(username,firstname,lastname)

VALUES ('$username','$firstname','$lastname')";



mysqli_query($conn, $sql);



}



?>

Insert.php file ka kam hai ki agar user correct otp code  enter karta hai to user ke information firstname,lastname,and username ko databse me store kar lena.
