PHPMailer is not sending mail with forgot username page - php

Question

Constructing Forgot UserName Page:
Withing php file is getting hosted under localhost xampp.
Using Gmail email address to send mail to another gmail address with username
No error, just mail is not sent.
I added the following files from Github inside the includes directory.
PHPMailerAutoload.php,
class.phpmailer.php,
class.smtp.php,
class.phpmaileroauth.php,
class.phpmaileroauthgoogle.php,
class.pop3.php
Then inside includes directory created "forgot_username_inc.php" UPDATED
Here is the php code for it
<?php
include_once 'db_connect.php';
include_once 'psl-config.php';
require_once 'PHPMailerAutoload.php';
require_once 'class.phpmailer.php';
require_once 'class.smtp.php';
require_once 'class.phpmaileroauth.php';
require_once 'class.phpmaileroauthgoogle.php';
require_once 'class.pop3.php';
$error_msg_username = "";
if (isset($_POST['email'])) {
// Sanitize and validate the data passed in
$email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL);
$email = filter_var($email, FILTER_VALIDATE_EMAIL);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
// Not a valid email
$error_msg_username .= '<p class="error">The email address you entered
is not valid</p>';
}
$prep_stmt = "SELECT username FROM client WHERE email = ? LIMIT 1";
$stmt = $mysqli->prepare($prep_stmt);
// check existing email
if ($stmt) {
$stmt->bind_param('s', $email);
$stmt->execute();
$stmt->store_result();
if (!($stmt->num_rows == 1)) {
// If no user with such email
$error_msg_username .= '<p class="error">No User Registered with that Email</p>';
$stmt->close();
}
}
else {
$error_msg_username .= '<p class="error">Database error Line 39</p>';
$stmt->close();
}
if (empty($error_msg_username)) {
if($stmt_username = $mysqli->prepare("SELECT username FROM *** WHERE email = ? LIMIT 1")) {
$stmt_username->bind_param('s', $email);
$stmt_username->execute();
$stmt_username->store_result();
$stmt_username->bind_result($username);
// user found
if ($stmt_username->num_rows == 1) {
// sending mail
$mail = new PHPMailer;
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP
authentication
$mail->Port = 587; // set the SMTP port for the GMAIL
server
$mail->Username = 'example#gmail.com'; // SMTP username
$mail->Password = 'password'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable encryption,
'ssl' also accepted
$mail->SMTPDebug = 2;
$mail->From = 'example#gmail.com';
$mail->FromName = 'Admin';
$mail->addAddress($email); // Name is optional
$mail->WordWrap = 50; // Set word wrap to 50
characters
$mail->isHTML(true); // Set email format to
HTML
$mail->Subject = 'User Name Forgot';
$mail->Body = 'Here is your UserName'.$username;
$mail->AltBody = 'Here is your UserName'.$username;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
//---End of Mail
} // end of userfound
} // end of prepare statement
if (! $stmt_username->execute()) {
header('Location: ../error.php?err=Username Search: FAILED');
exit();
}
$stmt_username->close();
header('Location: ./forgot_username_success.php');
exit();
}
}
?>
Error it shows:
Please log in via your web browser Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
What I did: Disable 2-way authentication.Allow less secure apps access.
clear browser cache. I also "unlock CAPTCHA"
https://accounts.google.com/DisplayUnlockCaptcha
Still failed.
UPDATE:
I used GMX instead of gmail & now it sending mails successfully.
