<?php
$userId = $_POST['logid'];
//$userName = $_POST['logName'];
$password = $_POST['logPassword'];
$account = $_POST['account'];
$teacher = "Teacher";
$student = "Student";


if ($account == $teacher) {
  # code...

  $sql = "SELECT * FROM teacherRecord WHERE email = '$userId' AND password='$password'";

  $result = mysqli_query($con,$sql);
  $check = mysqli_fetch_array($result);

  if(isset($check)){
    setcookie("email", $userId, time() + (86400 * 30), "/");
    echo $_COOKIE['email'];
    //echo "<script>window.location='profile.php'</script>";
  }
