Fatal error: Uncaught PDOException: SQLSTATE[HY093]:

Question

If someone can help me with this, I'm not good with php but I'm trying to learn but this problem I encounter makes my head hurt.

Here's the full error:

Fatal error: Uncaught PDOException: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens in C:\xampp\htdocs\website\register.php:34 Stack trace: #0 C:\xampp\htdocs\website\register.php(34): PDOStatement->execute(Array) #1 {main} thrown in C:\xampp\htdocs\website\register.php on line 34

<?php

include 'config.php';

if(isset($_POST['submit'])){

   $name = $_POST['name'];
   $name = filter_var($name, FILTER_SANITIZE_STRING);
   $email = $_POST['email'];
   $email = filter_var($email, FILTER_SANITIZE_STRING);
   $pass = md5($_POST['pass']);
   $pass = filter_var($pass, FILTER_SANITIZE_STRING);
   $cpass = md5($_POST['cpass']);
   $cpass = filter_var($cpass, FILTER_SANITIZE_STRING);

   $user_type = $_POST['user_type'];
   $image = $_FILES['image']['name'];
   $image_tmp_name = $_FILES['image']['tmp_name'];
   $image_size = $_FILES['image']['size'];
   $image_folder = 'uploaded_img/'.$image;

   $select = $conn->prepare("SELECT * FROM `users` WHERE email = ?");
   $select->execute([$email]);

   if($select->rowCount() > 0){
      $message[] = 'user already exist!';
   }else{
      if($pass != $cpass){
         $message[] = 'confirm password not matched!';
      }elseif($image_size > 2000000){
         $message[] = 'image size is too large!';
      }else{
         $insert = $conn->prepare("INSERT INTO `users`(name, email, password, image, user_type) VALUES(?,?,?,?)");
         $insert->execute([$name, $email, $cpass, $image, $user_type]);
         if($insert){
            move_uploaded_file($image_tmp_name, $image_folder);
            $message[] = 'registered succesfully!';
            header('location:login.php');
         }

Change this line:

$insert = $conn->prepare("INSERT INTO `users`(name, email, password, image, user_type) 
      VALUES(?,?,?,?)");

to:

$insert = $conn->prepare("INSERT INTO `users`(name, email, password, image, user_type) 
      VALUES(?,?,?,?,?)");

Because you want to use 5 parameters, you also need 5 ? marks.
