    Default Help wanted in implementing a special CAPTCHA

    If I wanted to have a required field where folk had to enter a very specific set of characters (which they knew by other means), could someone help me by saying quite specifically all things I would need to put into the form and what I would need to change in the Tectite form script please. Imagine as an example they need to enter:

    5BcTi

    for the form to be successfully submitted.

    Is everyone going to use the same characters or are they different for different people.

    If they are the same for everyone, then you could use Formmail's reverse captcha with a few modifications.

    If they are different, then you are going to have to use some other form of validation outside of formmail like php or javascript.

    In order to get a successful submission, everyone has to put in the same set of characters that they and I will know is correct for any particular time, the characters should *not* appear in the HTML source. This is for something that is additional to reverse captcha (which I assume is working fine and has been implemented already).

    I have not been able to get the normal captcha working and will make my own version with a twist... the only thing that is relevant here though is what would be a good exact input line in the form (given the string I give as example) and what would I put exactly in the processing form that sits on the server.

    Simply implement reverse captch per the directions but do not hide the first field. Hide only the second field which has "" for the value. Also do NOT specify a value for the first field even though that is what the directions say to do. Use "" for the value.

    The form will only submit if a user types in the random value you have entered for the first field in the formmail.php file.
