holy big text batman..

 

you are receiving these "notices" (they aren't errors) because you are attempting to call on $_POST values that do not exist upon page load.

 

if(isset($_POST['username']) && isset($_POST['password'])) {
    $username = $_POST['username'];
    $password = $_POST['password'];
}

Hello

 

Your problem looks to be on your form.

 

You have named the field "passsword" - note the incorrect spelling of password (you have added three S's).

 

The php script is then looking for 'password' - with the correct spelling. This is why you are getting undefined index. Your form is posting "passsword" but your php script is looking for "password" in the post array.

 

Hope that fixes it!
