Checking 'empty' on radio button

[tsfountain]

Hello all,

I'm trying to check the state of a radio button group using empty to run a post variable into a session variable.

HTML looks something like this:

[code]
<input type="radio" name="foo" value="bar1">BAR1</input>
<input type="radio" name="foo" value="bar2">BAR2</input>
[/code]

Then I'm checking (on submit) to see if they've acually selected a radio button.
[code]
if (!empty($_POST['foo'])) {
  $_SESSION['foo'] = $_POST['foo'];
}
else {
  echo " Yuo haven't filled in anything";
}
[/code]

The problem is it never gets to the else statement even if it is empty.

Any ideas?

It returns [i]Yuo haven't filled in anything[/i] for me as its reaching the else statement

use

if (isset($_POST['foo']))
