Radio buttons and confirmation buttons...

    For my website I need to create a confirmation page for people to give consent, they have to click the correct radio button in order to proceed to the next page. Does anyone know where I can get the code for this? Or what type of programming language I need to use?

    I need it so that when user presses on the confirmation button, that depending on whether or not they give consent, it directs them to either the next page in the site, or away from the website if they have selected the 'do not give consent' radio button.

    Anyone know what I'm talking about?

    Depends and what language your website is written in. If its just static HTML then it would help to know what type of webserver it's being hosted on, then we'll know what languages are supported.

    Here you are, a basic example:

    [php]<?php

    if(isset($_POST)){

    if(!$_POST){

    echo "You didn't select an answer";

    }

    if($_POST == "yes"){

    echo "You selected yes";
    //instead of the echo here you will want to redirect presumably? if so, delete the echo... line and uncomment the next line, replacing the location with your own
    //header("Location: sucess.htm");


    }

    if($_POST == "no"){

    echo "You selected no";
    //header("Location: fail.htm");

    }

    }

    ?>

    <html>
    <head>
    <title>Untitled Document</title>
    </head>

    <body>
    <form action="" method="post" name="frmLogin" id="frmLogin">
    <table width="400" border="1" align="center" cellpadding="2" cellspacing="2">
    <tr>
    <td width="150">Yes</td>
    <td><input name="group" type="radio" value="yes"></td>
    </tr>
    <tr>
    <td width="150">No</td>
    <td><input name="group" type="radio" value="no"></td>
    </tr>
    <tr>
    <td width="150"> </td>
    <td><input name="submit" type="submit" value="Submit"></td>
    </tr>
    </table>
    </form>
    </body>
    </html>
    [/php]

    I think I'm being stupid, but do I type this for the location part?:
    if($_POST['group'] == "yes"){


    Location: sucess.htm;


}

if($_POST['group'] == "no"){

  Location: fail.htm;

}

}
  
?>

    Not quite, you've got to use the brackets and inverted commas too i.e.

    [php]header("Location: success.htm");[/php]

    i changed them but now I'm getting this error:

    Warning: Cannot modify header information - headers already sent by (output started at /misc/25/000/102/320/6/user/web/edate.bravehost.com/consent.php:9) in /misc/25/000/102/320/6/user/web/edate.bravehost.com/consent.php on line 22


    any idea?

    I'm assuming your code looks like this:

    [php]
    <?php

    if(isset($_POST)){

    if(!$_POST){

    echo "You didn't select an answer";

    }

    if($_POST == "yes"){

    header("Location: success.htm");

    }

    if($_POST == "no"){

    header("Location: fail.htm");

    }

    }

    ?>
    [/php]

    Have you added anything?

    No I haven't changed anything except my file names, and I'm still getting an error!!
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<?php


if(isset($_POST['submit'])){

    if(!$_POST['group']){

        echo "You didn't select an answer";

    }

if($_POST['group'] == "yes"){

    header("Location: instruct.htm");

}

if($_POST['group'] == "no"){

    header("Location: error.htm");

}

}
  
?>

</body>
</html>

    Any idea??

    Yes, its because you've got
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>

    before the php code. You can't output any information to the browser before calling the header function in php.
