Email smtp: mail not send - no error

Let me write here the codes which work perfectly for me.

1. Upload your PHPMailer folder into your root folder, beside your App, public etc folders

2. Go to Config / Autoload, find your lines starting with public $psr4 =  (the line might be 42) :

PHP Code:

public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
        'Config'      => APPPATH . 'Config',
        'App' => APPPATH, // To ensure filters, etc still found

        'Forms' => ROOTPATH.'forms',
        'PHPMailer\\PHPMailer'=> ROOTPATH.'PHPMailer/src' 
    ]; 


3. On your Controller, include this just before your class ControllerName extends BaseController {...

PHP Code:

//mailer

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\OAuth;
use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\SMTP; 


4. mailing starts

PHP Code:

//mailing starts

$member_email = $this->request->getVar('member_email');
$name = $this->request->getVar('member_name');
$my_email = '[email protected]'; 

$mail = new PHPMailer();

$mail->isSMTP();
$mail->Timeout = 20;
$mail->SMTPDebug = 0;
//Set the hostname of the mail server
$mail->Host = 'this might be your server name. Check your mail settings';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "[email protected]";  
$mail->Password = "Password";  
$mail->setFrom('[email protected]', 'Welcome to my website ');
$mail->addAddress($member_email, '');

//Set the subject line
        
$message = 'Thanks for registering. You can login on our 
<a href="http://mywebsite.com/my_folder/login" target="_blank">Login</a> page.<br><br>Regards,<br>My Website.com';
  
$name_greeting = 'Dear ' .$name;

$mail->isHTML(true);
    $mail->Subject = 'My Web Site - Welcome.';
    $mail->Body    = "$name_greeting,<br /><br />$message";
    $mail->CharSet = 'utf-8';

$mail->send();

    $session = \Config\Services::session();
    $session->setFlashdata('success', 'Thanks for registering. You wil receive an email etc.');
    return redirect()->to(site_url('en/login'));

//mailing ends
