Human Check

[Jane_F]

Hi there I have created one or two basic web sites (for others - local charities) by using Front Page but really have limited knowledge about scripting languages. One of my sites has an enquiry form so that visitors can ask a question. This is then emailed to the charity when the visitor presses the submit button. They are now getting lots of spam and want a way to stop it. I have been looking to find a very simple Human Check but have not been able to understand how they work. I thought i would just put a simple "are you human" Yes/No dropdown box or radio button but i dont know how to validate the visitor response so that they can only submit if they answer correctly. I would be grateful for any help........ Thank you .

You can use a captchas (http://en.wikipedia.org/wiki/Captcha) for this, here is a good site: http://www.captcha.net/ (http://www.captcha.net/)

thanks for your reply. I already have an account there and spent all day yesterday looking at Captcha for simple instructions how to put it onto the website and get it working - I need something simple i can understand. I couldnt find it there.

You can do it with php and have the form submit straight threw there. Like at the last line of your form have it be what is the first letter of the alphabet. Then in the php have if ($inputfield == "a") {
mail("address", subject, message);
} else
{
echo ("You Failed the verify please reverify.");
}

Something like this I could give you a better example if you post your form's code or a link to it.
