I want to send a qrCode to an email using PHPMailer - php

Question

This is my qr_code.php file:
require_once 'phpqrcode/qrlib.php';
function create_QrCode($name){
$path ='images/';
$file=$path.uniqid().".png";
$text=$name;
QRcode::png($text, $file);
}
?>
This is my mail.php file:
require('qr_code.php');
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'C:\xampp\htdocs\contact_form\vendor\autoload.php';
#Initialize PHPMailer
function Send_email($mailFrom,$User_name,$phone,$city,$facebook,$qrCode){
$mail= new PHPMailer();
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail ->isSMTP();
$mail ->SMTPAuth =true;
$mail ->SMTPDebug =3;
$mail ->SMTPSecure="tls";
$mail ->Port=587;
#Connection settings
$mail ->Host= "smtp.gmail.com";
$mail ->Username="email#gmail.com";
$mail ->Password="password";
$mailTo ='email#gmail.com';
$mail-> IsHTML(true);
$mail ->SetFrom($mailFrom,$User_name);
$mail ->addAddress($mailTo);
$mail->AddReplyTo($mailFrom, $User_name);
#Create email
$mail->Subject ='I would like to come at the party ! ';
$mail->Body ="Name: $User_name<br>
Phone No: $phone<br>
City: $city<br>
Facebook: $facebook<br>
Email id: $mailFrom<br>
QrCode: $qrCode";
return $mail->Send();
}
This is my functionalities.php file (where I want to send the email):
$qrCode=create_QrCode($name);
if(!Send_email($email,$name,$phone,$city,$facebook,$qrCode))
{
echo "Mail NOT SENT";
}
else
{
echo"Mail Sent !";
}
header('Location:redirecting_page.html');
}
I have tried different modes, but I don't know how to figure it out. I know in the QRCode function, I am generating it to a file, but this is what I succesfully created until now. I know the QRCode function is the problem, but I don't know how to fix it. Can somebody please help me?
