Hello Friends, In this blog post(PHP Email Verification Script For Downloading E-Books) PHP Email Verification Script, I am going to explain one interesting functionality of email verification when any user tries to download an E-Book using PHP.

But you can use this email verification PHP script(PHP Email Verification Script For Downloading E-Book) for other events too. You can send an email verification link after user registration, file download, verification of users, etc.

Using this PHP code(PHP Email Verification Script For Downloading E-Book) or email verification script you can easily verify the email address while they download the e-book.

You can also consider this as a double opt-in form where the user is verified twice|PHP Email Verification Script For Downloading E-Book|

First time when a user enters the email id in the given form.|PHP Email Verification Script For Downloading E-Book|

A second time when a user clicks the verification link sent to their email inbox.

Within this blog post, we are going to cover User registration with email verification in PHP and email verification in PHP MySQLi,…

…How to send an email after registration with an activation link in PHP, PHP code for downloading a file from a folder, Email OTP verification in PHP, Mail PHP Download, PHP download file from server to client, Email verifier PHP script…

Why mail function is not working in PHP? How to send emails automatically using PHP? Send confirmation email after registration in PHP, How to send an email after registration with the activation link in PHP, PHP login, and registration with email mobile verification, PHP email confirmation, Email verifier PHP script.

In this functionality(PHP Email Verification Script For Downloading E-Book), the user will see a form for downloading an E-Book. See the image below.

When users enter their name and email ID and submit the form then one verification link(random) link will be sent to their address.

When users click the email verification link then they will be redirected to a page where they can easily download the E-Book by just clicking the download link given. See the image below.

What is the benefit of this email verification?

This email verification will help you to get the real users who are downloading the E-Book. The only real user can complete this verification process with their valid email address.

This will surely reduce the spamming of users who can make your network busy with their promotional links and phishing activity.

Software Used for building this functionality:

NetBeans IDE.

Xampp Server.

What is the procedure to build this functionality of ebook download using the email verification process?

This is a very simple process of downloading the ebook after a successful email verification, you just need to follow the step-by-step procedure given below.

Start your Apache server using your Xampp Control Panel.

Now open your NetBeans IDE and create a project say E-Book_Email_Verification though you can have any suitable name as per your wish.

Now make a few files and folders as shown in the image below.

Note: Here you would also need to download two images one for an e-book(width:289, Height:228) and another for the download(small) button, and keep them in the image folder.

You would also need to download one sample pdf to show the downloading functionality, so just download a sample pdf file and keep it in the ebook folder.

Now copy and paste the code below one by one into the respective files.

index.php:

[code]
<?php
include "classes/class.phpmailer.php"; // include the class name

$hash = md5(rand(0, 1000));

//echo" you can buy this book Please click on the link";
echo "<script type='text/javascript'>alert('you can buy this book Please click on Download Button')</script>";
header('location:download.php');
}
}

if (isset($_POST['dsubmit'])) {
$emailid = $_POST['textmail'];

$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only

$mail->AddAddress("$emailid");

} else {

Important Gmail Account Setting:

You are almost done with this functionality but do not forget to make this important setting given below as you would not be able to send the email without this setting in your Gmail account.

You need to make a 2-step verification, see the image below.

• Now make another change by turning ON the less secure apps, see the image below.
