[LaFougère]

Im trying to do an email verification to register to my website but the mail is not sending when i click the button to send the form
Im using SMTP2GO but because my script dont work, im not sure about how to use it.

Here is the script:

require 'vendor/autoload.php';
session_start();
try {
    $bdd = new PDO('mysql:host=127.0.0.1;dbname=users;charset=utf8;', 'admin', 'donotlookthere:)');
} catch (Exception $e) {
    die('Erreur : ' . $e->getMessage());
}
if (isset($_POST['envoi'])) {
    $prenom = htmlspecialchars($_POST['prenom']);
    $nom = htmlspecialchars($_POST['nom']);
    $email = htmlspecialchars($_POST['mail']);
    $password = password_hash($_POST['password'], PASSWORD_DEFAULT, ['cost' => 12]);
    $password_confirm = password_hash($_POST['password_confirm'], PASSWORD_DEFAULT);
    $checkEmail = $bdd->prepare("SELECT * FROM users WHERE email = ?");
    $checkEmail->execute(array($email));
    $cle = rand(100000000000, 999999999999);
    if ($checkEmail->rowCount() > 0) {
        $error_message = "Email déjà utilisé.";
    } elseif ($_POST['password'] !== $_POST['password_confirm']) {
        $error_message = "Les mots de passe ne correspondent pas.";
    } else {
        $insertUser = $bdd->prepare("INSERT INTO users (prenom, nom, email, password, cle, confirm) VALUES (?, ?, ?, ?, ?, ?)");
        $insertUser->execute(array($prenom, $nom, $email, $password, $cle, 0));

        $recup_user = $bdd->prepare('SELECT * FROM users WHERE email = ?');
        $recup_user->execute(array($email));
        if($recup_user->rowCount() > 0) {
            $user_info = $recup_user->fetch();
            $_SESSION['id'] = $user_info['id'];
            $_SESSION['prenom'] = $user_info['prenom'];
            $_SESSION['nom'] = $user_info['nom'];
            $_SESSION['email'] = $user_info['email'];
            $_SESSION['password'] = $user_info['password'];
            $_SESSION['cle'] = $user_info['cle'];
            $_SESSION['confirm'] = $user_info['confirm'];
            
            function smtpmailer($to, $from, $from_name, $subject, $body)
            {
                $mail = new PHPMailer(true);
                $mail->IsSMTP();
                $mail->SMTPAuth = true;

                $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
                $mail->Host = 'mail.smtp2go.com'; // Hôte SMTP2GO
                $mail->Port = 2525;  // Port SMTP2GO (2525, 587, ou 465)
                $mail->Username = 'teamgeek.fr'; // Nom d'utilisateur SMTP2GO
                $mail->Password = 'donotlookthere:)';   // Mot de passe SMTP2GO

                $mail->setFrom($from, $from_name);
                $mail->addAddress($to);
                $mail->Subject = $subject;
                $mail->Body = $body;
                
                $mail->Send();
            }

            $to   = $email;
            $from = 'nepasrepondre.superannales.bia@teamgeek.fr';
            $name = 'Super Annales BIA';
            $subj = 'Vérification de votre adresse email';
            $msg = 'Cliquez sur ce lien pour confirmer votre adresse email: https://teamgeek.fr/annales-bia/verify.php?email='.$email.'&cle='.$cle;

            smtpmailer($to, $from, $name, $subj, $msg);
        }
    }
}

please add

error_reporting(E_ALL); 
ini_set("display_errors", 1);

at the beginning of the code and

                $mail = new PHPMailer(true);
                $mail->IsSMTP();
                $mail->SMTPAuth = true;
                // set debugging
                $mail->SMTPDebug  = 1;

based on these information that you should see you should be able to figure out why the email is not sending, if not you can paste the whole message here (without sensitive data)
