<div class="body">
  <form method="post" action="register.php">
   <?php include('errors.php'); ?>
   <div class="input-group">

   <div class="input-group">
     <button type="submit" class="btn" name="reg_user">Register</button>
   </div>
  </form>
  </div>
 </div>
</body>
</html>And this is my server.php
<?php
session_start();
// initializing variables
$username = "";
$email    = "";
$fullname = "";
$image = "";
$errors = array(); 
// connect to the database
$db = mysqli_connect('localhost', 'root', '', 'school_database');
// REGISTER USER
if (isset($_POST['reg_user'])) {
  // receive all input values from the form
  $target = "../images/".basename($_FILES['image']['name']);
  $username = mysqli_real_escape_string($db, $_POST['username']);
  $fullname = mysqli_real_escape_string($db, $_POST['fullname']);
  $image = mysqli_real_escape_string($db, $_FILES['image']['name']);
  $email = mysqli_real_escape_string($db, $_POST['email']);
  $password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
  $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);
  // form validation: ensure that the form is correctly filled ...
  // by adding (array_push()) corresponding error unto $errors array
  if (empty($username)) { array_push($errors, "Username is required"); }
  if (empty($email)) { array_push($errors, "Email is required"); }
  if (empty($email)) { array_push($errors, "Image is required"); }
  if (empty($fullname)) { array_push($errors, "Full Name is required"); }
  if (empty($password_1)) { array_push($errors, "Password is required"); }
  if ($password_1 != $password_2) {
 array_push($errors, "The two passwords do not match");
  }
  // first check the database to make sure 
  // a user does not already exist with the same username and/or email
  $user_check_query = "SELECT * FROM teachers WHERE username='$username' OR email='$email' LIMIT 1";
  $result = mysqli_query($db, $user_check_query);
  $user = mysqli_fetch_assoc($result);
  
  if ($user) { // if user exists
    if ($user['username'] === $username) {
      array_push($errors, "Username already exists");
    }
    if ($user['email'] === $email) {
      array_push($errors, "email already exists");
    }
  }
  // Finally, register user if there are no errors in the form
  if (count($errors) == 0) {
   $password = md5($password_1);//encrypt the password before saving in the database
   $query = "INSERT INTO teachers (username, full_name, email, img, password) 
       VALUES('$username', '$fullname', '$email', '$image', '$password')";
   mysqli_query($db, $query);
    if (move_uploaded_file($_FILES['image']['tmp_name'],$target)) {
      echo 'File Uploaded Successfully';
     }else {
      echo 'Something went wrong';
     }
   $_SESSION['username'] = $username;
   $_SESSION['success'] = "You are now logged in";
   header('location: ../admin/index.php');
  }
}
?>But when I try to run my register.php it says me
Notice: Undefined index: image in C:\xampp\htdocs\custom\jcschool\php\server.php on line 17
Notice: Undefined index: image in C:\xampp\htdocs\custom\jcschool\php\server.php on line 20 which are these two lines,
- $target = "../images/".basename($_FILES['image']['name']); 
- $image = mysqli_real_escape_string($db, $_FILES['image']['name']); 
Please, someone give the solution. What should I Do now?
