I need a daily limit on a competition

[Guest_imported]

Can anyone help me, I need to include some sort of code in a competition that I'm going to run on a website so that people can only submit their answer once a day and if they try to do it more than once, their submission will be ingored. Can anyone help me?

Thanks,

Matt

Hi,

You're gonna need a DB to do that. Store the IP-address and the date on which the user fills in an answer.

Check if the IP-address already exists.
If so, check if the last registered date is at least one day older than the current. If so, update the clients record. If not, show a message that the user has already posted an answer.

If it doesn't matter that much you can always use cookies that expire in a day, but than the client has to enable cookies.
And ofcourse, it's very easy to cheat with cookies.

Not that it ain't easy to cheat with an IP but that's out of your hands.

Hope this helps

Gtz,

Kristof

PS: Capturing a client's network card number would be even better, since you can't change that. But I don't know how to accomplish that. (If it is even possible).

How are you tracking the entries? An on-line database, email or what?
