Hi, i cant remember how to get the value of the option box

I have 3 radio buttons on a page all called radio (so it unchecks one when another is ticked) but when i submit the page how do i know which on is checked i.e just get it to display on page

Let me know if you want more info

[CODE]
<input name=”radio” type=”radio” value=”radiobutton”>
[/CODE]

Cheers Adam

@k0r54authorDec 07.2004 — Hi ok so for example

if i have a form with this in

<input name="radio" type="radio" value="1">

and a php page that the form links to with this in it

[code=php]
<?PHP
$Radio1 = $_POST[1];

echo "$Radio1";
?>
[/code]

Will that echo 1, (the value of the radio button 1)

@NogDogDec 07.2004 — Yes, however I would reference the _POST array associatively (much easier to maintain):

[code=php]
<?PHP
$Radio1 = $_POST['radio'];
echo "$Radio1";
?>
[/code]
