I really need help im tired and retless

 

Hi,

I'm not sure what you need the Javascript for? I would remove that and also remove any pure html from your <?php tags. Something like this for the html:

<form action="" method="post">
<input type="radio" name="radio" value="value1"/>
<input type="radio" name="radio" value="value2"/>
<input type="radio" name="radio" value="value3"/>
<input type="hidden" name="submitted" value="1"/>
<input type="submit"/>
</form>

HTML:

Then the php code:

if(isset($_POST['submitted']))
{
    echo $_POST['radio'];
}

PHP:

I *think* that should work. (although completely untested!)

 

thnx mfscripts

can we do it without submitting?

when the radio button is clicked, the value of the radio button is printed automatically.

hmmmmmmmmmmmmmm.....
