// ========================= Email Sender ==========================

// Button click to send
if (array_key_exists('btn_send_email', $_POST)) {
    send_email();
}

use PHPMailer\PHPMailer\PHPMailer;

// Replace these variables with your Google Workspace email and app-specific password
$senderEmail = "sender@myemail.com";

$recipientEmail = "recipient@email";

$subject = "Your QR Code";
$message = "Please find your QR code below.";

// Construct the URL for the Google Chart API with your dynamic data
$qrCodeData = "https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=" . urlencode("https://myWebSiteURL/qr/scan.php?id=" . $id);

// Create a PHPMailer instance
$mail = new PHPMailer;
//$mail = new PHPMailer(TRUE);

// Enable debugging (remove this line in production)
$mail->SMTPDebug = 2;

// Set the mailer to use SMTP
$mail->isSMTP();

// Specify the SMTP server

// Enable SMTP authentication
$mail->SMTPAuth = true;

// SMTP username (your Google Workspace email)
$mail->Username = $senderEmail;

$mail->Password = $appPassword;

// Enable TLS encryption
$mail->SMTPSecure = 'tls';

// Set the SMTP port (587 for TLS, 465 for SSL)

// Set the 'From' email address
$mail->setFrom($senderEmail);

// Set the 'To' email address
$mail->addAddress($recipientEmail);

// Set the email subject
