I would like to send my image to a folder on my server and save the relative path in the database so that I can use it later, but my current code does not work, it is impossible to move the image to my user-images folder

<div class="container">
        <h2>Inscription</h2>
        <form method="post" action="" enctype="multipart/form-data">
                    <div class="upload-container" onclick="document.getElementById('image').click()">
                <label for="image">Glissez et déposez une image ici ou cliquez pour sélectionner un fichier</label>
                <input type="file" id="image" name="image" accept="image/*" style="display: none" onchange="previewImage(event)" required>
                <img id="preview-image" alt="Aperçu de l'image">
            </div>
            <input type="text" name="name" placeholder="Votre Nom" required>
            <input type="email" name="email" placeholder="Votre Email" required>
            <input type="password" name="password" placeholder="Mot de passe" required>

            <button type="submit" name="register">S'inscrire</button>
        </form>
  <?php if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["register"])) {
      // Connexion à la base de données
      $servername = "localhost";
      $username = "admin";
      $password = "password";
      $dbname = "chat_app";

      $conn = new mysqli($servername, $username, $password, $dbname);

      if ($conn->connect_error) {
          die("Connexion échouée : " . $conn->connect_error);
      }

      $name = $_POST["name"];
      $email = $_POST["email"];
      $role = "user";
      $password = password_hash($_POST["password"], PASSWORD_DEFAULT);
      $image_destination = "User-images/" . basename($_FILES["image"]["name"]);

      if (
          move_uploaded_file($_FILES["image"]["tmp_name"], $image_destination)
      ) {
          // Le fichier a été téléchargé avec succès
          $sql = "INSERT INTO Utilisateurs (nom, email, mot_de_passe, role, image) VALUES ('$name', '$email', '$password', '$role', '$image_destination')";
          if ($conn->query($sql) === true) {
              header("Location: index.php");
              exit();
          } else {
              echo "<p>Erreur : " . $sql . "<br>" . $conn->error . "</p>";
          }
      }

      $conn->close();
  } ?>
    </div>
