Encoding Hidden Fields

[Nixon]

Hi,

I have on my website a form, which users have to type certain words into textboxes and depending on the word they get points. The only problem is I keep the correct word in a hidden field on my form, so if the user looks at the source then the secret word is available there. Is there anyway to encode it or hide it? Oh yeah, I can't just put the word somewhere else.

<input name="pointfield" type="text" id="pointfield">
<input name="numberfield" type="hidden" id="numberfield" value="91">
<input name="advertnum" type="hidden" id="advertnum" value="advert1">
<input name="pointvalue" type="hidden" id="pointvalue2" value="1"></td>

The secret word is numberfield but I would also liek to encode the name of the point value field.

i think i have a solution...
but can you take us through an example of the process you do once the form is submitted?

If it goes to another page where it checks if the word typed in is the same as the hidden field... well... you might need to do some tweaking..
But if that 91 is attached to that..
(say, if you have 100 words, 91 is advert1)..
then you only need to pass the 91..

on the script that checks the answer.. build an array:

$words[0] = ...;
$words[1] = ...;
.
.
.
$words[91] = "advert1";

Then:

if($POST["pointfield"] == $words["numberfield"])
{
//award $POST["pointvalue"];
}

couldn't you use session variables instead of hidden form fields?
