Do you really have an element with the name `$pwd`, dollarsign and all ? — adeneo, Feb 24 '15 at 10:59
(Not related to the question:) Furthermore you might consider using "\n" (adding newline character) at the end of your strings instead of really ending with a newline. — matthias, Feb 24 '15 at 11:39

Instead of $pwd = $_POST['$pwd']; use $pwd = $_POST['pwd'];

Still getting the same index error and the undefined variable. – Tony Reed Feb 24 '15 at 11:06

Then maybe your password input name is not 'pwd'? Check what is in your $_POST array - print_r($_POST); - one of the keys in that array will be your input password name. – n-dru Feb 24 '15 at 11:08

$pwd = $_POST['$pwd'];

I guess this is meant to be:

$pwd = $_POST['pwd'];

But it depends on what name the password field have in your form. If the name of the password field on the form is password, then make it $_POST['password']

if you have...

<input type="password" name="pwd">

then in your php script, you should call it

$pwd = $_POST["pwd"];

take note of the name attribute.
