Stop people clicking lots of crimes or refreshing

[jaymo]

I've seen this around on a few games but can't get my head around it, is there a way that the user can do crimes but if they keep clicking then it says a message or if you refresh? Ive seen games with a url with a hash or something like

game.com/crime.php?id=4&hex=8b79c8a59b38e53cb51f53b181e1f27c

I will pay back to the community by sharing some of my custom mods again soon as a thankyou.

Thanks again

You could use timestamps. It would work like this:

1) User does crime, the time stamp is inserted to a field in db.

2) User does another crime. (New time stamp - time stamp in db). If it is below 2 (seconds), then update another field in db to 2.

3) Same as number 2, update teh second field in db to 3. If the value is over 2, then update the second db feild to 0 so it will reset.

4) If this value reaches for example 5, the user gets an error message.

That's just a rough example of how it works. I don't have time to make a script for it, but I am sure it wouldn't be hard at all to implement to a game.

Add to grpgusers

Captcha? Or am I getting the wrong idea of what your trying to do?

[Ishraq]

Ive got something good. It doesnt require any any database insertions. Just a few codes controlled by session. And it works perfectly.

Il post it up tommorow.

Yeah, I am trying to fix it to the Captcha way, but haven't succeeded yet, once its done i'll update the code.

Use PHPGD everytime they do a crime create a new random generated code and turn it into an image.

[Michael Evans]

there is a good way to do this ehh my mind has gone blank and im getting mixed up but could you just not alow the same data sent twice simple bit like cross site forgery? not sure im no coder

[Djkanna]

How about?

/*
Logically this would be placed, where you would put your links to do crimes
*/
$_SESSION['crimeCode'] = md5(uniqid(null, true));
echo '<a href="dosomecrime.php?crimeID=1&code='.$_SESSION['crimeCode'].'" title="Do Crime">Do it nao</a>';

/* 
Then this would be where you have your logic for the crimes.
*/
if (array_key_exists('code', $_GET) && is_string($_GET['code']) && $_GET['code'] == $_SESSION['crimeCode']) {
   //Do some crime stuff.
   echo 'Yay you did a crime, bet you feel proud.';
   //Change the 'code'.
   $_SESSION['crimeCode'] = md5(uniqid(null, true));
} else {
   //Screw 'em.
   echo 'Eh, you hit refresh didn\'t you?';
}

aye would give you my crimes code works with tokens but mines have points and other stuff added to it
