Hello,

Try following the steps:

1. Upload the PHPMailer files to your server. You can upload the files using an FTP client or the file manager in cPanel.

2. Include the PHPMailer autoload file in your PHP script using the path to the PHPMailer files on your server:


require_once '/path/to/phpmailer/src/PHPMailer.php';
require_once '/path/to/phpmailer/src/SMTP.php';
require_once '/path/to/phpmailer/src/Exception.php';

Replace /path/to/phpmailer with the actual path to the PHPMailer files on your server.

3. Use the PHPMailer code as you normally would, making sure to update any paths or configurations as needed for your server.
modify your existing code :

require_once '/path/to/phpmailer/src/PHPMailer.php';
require_once '/path/to/phpmailer/src/SMTP.php';
require_once '/path/to/phpmailer/src/Exception.php';

$mailto = $_POST['mail_to'];
$mailSub = $_POST['mail_sub'];
$mailMsg = $_POST['mail_msg'];

$mail = new PHPMailer\PHPMailer\PHPMailer(true);
$mail->isSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->Username = "[email protected]";
$mail->Password = "accountsamplepassword";
$mail->setFrom("[email protected]");
$mail->Subject = $mailSub;
$mail->Body = $mailMsg;
$mail->addAddress($mailto);
$mail->addAttachment('pdf_files/reservation.pdf', 'reservation.pdf');

if (!$mail->send()) {
    echo "Mail Not Sent: " . $mail->ErrorInfo;
} else {
    echo "Mail Sent";
}

Make sure to update the paths and configurations in the code to match your server setup.
