How to get the value from a text field and pass it into a variable?

Question

I have the following form.

 <form name="cookieform" id="login" method="POST">
 <input type="text" NAME="username" id="username" class="text" maxlength="30" />
 </form>

What I would like to do is to grab the value from the text field and place it into a PHP variable. I have the following code.

<?php
  $get_username = $_POST['username'];
  print($get_username);
?>

thanks

Solution

Every time you hit the submit button, it will post the value of the input. This will set your PHP variable every time.

Update: Patrioticcow said his variable isn't returning anything. Something that should have been included in the question, but now we have that information.

echo $yourvariable;

Instead of print. This will work.
