How to show what someone has put into a form if they make a mistake?

[darthmahon]

Hey,

Ok I have the following at the top of my form page:

<?
session_start();
//user messages
$required_missing_msg = 'Required Fields Missing';
$success_msg = 'Success';
$fail_msg = 'Error';

//email information
$email_user = 'email';
$email_domain = 'domain.com';

$email_from_user = 'enquiry';
$email_from_domain = $_SERVER['SERVER_NAME'];

$mail_subject = "SkIN Online Form";

//init code
$show = "init";
//get self filname
$fullpath = split('/',$PHP_SELF); $c = count($fullpath); $c--; $self = $fullpath[$c];

if ($_POST)
{
    //get list/put form variables into array post_name => post_value
    $required = explode(",", $_POST['required']);
    $data = array();
    foreach($_POST as $key => $value)
    {
        if(($key!='required')&&($key!='Submit')&&($key!='PHPSESSID')&&($key!='sid'))
        {
            $data["$key"] = $value;
            if (empty($value)) //check for required
            {
                foreach($required as $req)
                {
                    if($key==$req)
                    {   

                        //$data["$key"] = '!*Required*!';
                        $msg = $required_missing_msg;
                        $show = "form";
                    }
                }
            } else // add to message
            {
                $message .= $key.": \n".$value."\n \n";
            }
        }
    }
    if ($show == "init")
    {
        //put data into mail and send
        $toaddress = $email_user.'@'.$email_domain;
        $fromaddress = "From: ".$email."\n";

    $email = mail($toaddress, $mail_subject, $message, $fromaddress);

    //check for sending error
    if ($email)
    {
        $msg = $success_msg;
        $show = "Msg";
    } else
    {
        $msg = $fail_msg;
        $show = "Msg";
    }
}
}

function selector($label, $data, $input_data)
{
    if ($data==$input_data)
    {
        echo ' checked';
    }
}
?>

I have this at the top of my form:

<? echo $msg; ?>
<? if ( ($show == "form") || ($show == "init") ){ echo ?>
    <form name="feedback" method="post" action="<? echo $self.'?'.strip_tags(SID);?>">

and this at the bottom of my form:

<? ;} ?>
</form>

I have a hidden field that lists all of the fields that are required. Now, when a user submits this and they miss out something that is required, it loads the form again, but does not fill in what they had already filled in. So if I had a really long form and they answered 9 out of 10 required fields, it will tell them to try again but it deletes everything in the other 9 fields. Any ideas how I get it to show the results? I've tried:

value="<? echo $variable;?>"

No luck.

Cheers,
Chris

if register globlas are turned off, then you need to declare $variable as $_POST['variable']

example:

<?
echo "<form method=POST  action=$_SERVER['PHP_SELF']>
<input type=text name=input value\"" . $_POST['variable'] . "\"> <input type=submit >
</form>";
?>

hope this helps.
