Why doesn't it put it in a folder?

Question

PHP

Hello! I am creating a personal account on my website, and during registration I ran into a problem that the user's avatar is not entered in the folder.

<form class="form" action="includes/signup.php" method="POST">
                		<div class="form__group">
                			<input class="form__control" name="name" type="text" placeholder="Ваше имя">
                			<input class="form__control" name="login" type="text" placeholder="Логин">
                            <input class="form__control" name="email" type="email" placeholder="Почта">
                            <input class="form__control" name="avatar" type="file">
                			<input class="form__control" name="password" type="password" placeholder="Пароль">
                			<input class="form__control" name="password_confirm" type="password" placeholder="Повторите пароль">
                			<div class="btn__sign">
                				<button class="btn">Зарегистрироваться</button>
                				<a class="singin" href="auth.php">Вход</a>
                			</div>
                		</div>
                	</form>

<?php
session_start();
require_once "config.php";

  $name = $_POST['name'];
  $login = $_POST['login'];
  $email = $_POST['email'];
  $password = $_POST['password'];
  $password_confirm = $_POST['password_confirm'];

  if($password == $password_confirm) {

    $path = 'static/avatar/' . time() . $_FILES['avatar']['name'];
    move_uploaded_file($_FILES['avatar']['tmp_name'], '../' . $path);
    if (!move_uploaded_file($_FILES['avatar']['tmp_name'], '../' . $path)) {
      $_SESSION['message'] = 'Ошибка при загрузке фотографии!';
      header('Location: ../register.php');
    }
    $password = md5($password);
    mysqli_query($connection, "INSERT INTO `users` (`id`, `name`, `login`, `email`, `password`, `avatar`) VALUES (NULL, '$name', '$login', '$email', '$password', '$path')");
      $_SESSION['message'] = 'Регистрация прошла успешно!';
      header('Location: ../auth.php');

  } else {
    $_SESSION['message'] = 'Пароли не совпадают!';
    header('Location: ../register.php');
  }

?>
