<h5>Sign In</h5>
<form action="login_action.php" method="post">
<input type="text" name="username" placeholder="username">
<input type="password" name="password" placeholder="password">
<button type="submit">Login</button>
$dbCon = mysqli_connect('localhost','root','','dbase');
    die('Could not Connect MySql Server:' .mysql_error());
$sql="SELECT * FROM userlevels WHERE uname='$username' and pass='$password'";
if(mysqli_num_rows($result) > 0){
$rows = mysqli_fetch_assoc($result);
if ($rows['userlevel'] == '1' || $rows['userlevel'] == '2' || $rows['userlevel'] == '3' || $rows['userlevel'] == '4') {
 header('location: user.html');
echo "<script>alert('Access Denied!');
<!DOCTYPE html>

  5. Here we defined and executed database ‘dbase’ connection then its referred by variable ‘$dbCon’. Using method ‘post’ we collected users form details of ‘username, password’ and stored to respective variables ‘$username,$password’.
  6. We defined select query with condition to checks in table ‘userlevels’ which row match with user given details then query stored to variable ‘$sql’.Using if condition we checks whether row count greater than ‘0’ or not.
  7. If its greater then we checking that users userlevel from database and redirected to ‘user.html’ page otherwise it throws error message and redirected to login form. In user html page we just displayed welcome message for valid users.
