Guest boshok Posted October 11, 2005 Share Posted October 11, 2005 I'm building a role playing game, it all works but one.I'm creating a secret link system, it means that some gets a turn when he goes to a link for example:http://mo.aasf.nl/secretlink.php?link_id=35 en than you press klik.But now the problem, a bot can easy press the button 'klik', I want a person to press klik not a bot.Does anyone know how to solve this problem? Maybe with images and letters?thx guys. Link to comment Share on other sites More sharing options...
Ache Posted November 5, 2008 Share Posted November 5, 2008 Easiest way is to generated a random number.Display the number to the user.Have the user type the number in e.g. a form.Validate if the user has typed in the correct number.If so take him to the page you want him to see.
