Hello,

I am trying to create a login page and after I enter the username and password this error appears. I still wonder why?

Notice: Undefined index: username in C:\xampp\htdocs\SquprimeRevise\loginproses.php on line 95

Notice: Undefined index: password in C:\xampp\htdocs\SquprimeRevise\loginproses.php on line 96

line 95: $username=$_POST['username'];
line 96: $password=$_POST['password'];

The login suppose to be correct.

login.php

<?php include('loginproses.php'); ?>

Login.php page:

Line 20 - add the attribute name="username" input element
Line 23 name="password" to the input element

The id attribute doesn't get passed to the server, but the namea attribute does.
