PHP Passing Hidden Form Field
Hey everybody

I have a php page with the following form on it:

PHP Code:
        <form action="" method="post">
        <input type="hidden" name="random" value="<?php echo $random?>" />
            <table width="100%" border="0" cellspacing="0" cellpadding="0">
                <tr>
                    <td align="center">
                        Code 1
                        <br />
                        <input name="code1" type="text" />
                    </td>
                    <td align="center">
                        Code 2
                        <br />
                        <input name="code2" type="text" />
                      </td>
                    <td align="center">
                        Code 3
                        <br />
                        <input name="code3" type="text" />
                      </td>
                </tr>
                <tr>
                     <td align="center">
                        Code 4
                        <br />
                          <input name="code4" type="text" />
                      </td>
                    <td align="center">
                        Code 5
                        <br />
                        <input name="code5" type="text" />
                      </td>
                    <td align="center">
                        Code 6
                        <br />
                        <input name="code6" type="text" />
                    </td>
                </tr>
                <tr>
                    <td colspan="3" align="center">
                        <br />
                        <input type="submit" name="submit" value="Submit" />
                        &nbsp;&nbsp;&nbsp;&nbsp;
                        <input type="reset" name="reset" id="reset" value="Reset" />
                       </td>
                </tr>
            </table>
        </form>
In order to determine where the user goes when submitting the form, I have the following code at the top of the same page:

PHP Code:
$random rand(150000950000);
session_start();
if(isset(
$_POST['submit']))
{
$strCode1 $_POST['code1'];
$strCode2 $_POST['code2'];
$strCode3 $_POST['code3'];
$strCode4 $_POST['code4'];
$strCode5 $_POST['code5'];
$strCode6 $_POST['code6'];

$code1 strtolower($strCode1);
$code2 strtolower($strCode2);
$code3 strtolower($strCode3);
$code4 strtolower($strCode4);
$code5 strtolower($strCode5);
$code6 strtolower($strCode6);

if ( 
$code1 == "this" && $code2 == "code" && $code3 == "works" && $code4 == "really" && $code5 == "well" && $code6 == "yay" ) { 
    
$_SESSION['confirmed'] = true;    
    
header('Location: yay.php');
    exit;
} else {
    
$_SESSION['confirmed'] = false;
    
header('Location: boo.php');
    exit;
}

That works perfectly, as far as getting the user to the correct page, based on if they put in the correct code or not.

However, what I want to do, is access the number that is generated by this line:

PHP Code:
<input type="hidden" name="random" value="<?php echo $random?>" />
on either "yay.php" or "boo.php".

I've tried $_GET and $_POST when trying to access it on those pages, but can't seem to get it right.

Any ideas or suggestions are greatly appreciated

Don't exactly follow.

$_POST['random'] isn't set?

You may need an id and a name

When opening a dialog in Visual Basic, Visual C# or other programming languages Windows has to know the name of the dialog. This I believe is the case here. Instead though the ID and Name is needed. The server needs to know where to place the charactors. I believe it's the server that's involved here.
