Hello,

I am setting up a page on my site where visitors vote for their favourite photo.

I want to limit each visitor to only one vote.

Is it possible to track their ISP identification and then block it from the form entry field once they have voted?

If not, are there any other ways of only allowing one vote per visitor?

BTW: I already put in a script to block multiple form submissions, but that isn't quite the same thing.

Thanks,

Neil

And I just tried adding this script: onSubmit="submitonce(this)"

which works during the same session (before reloading the page), but it cancels out another function (the required fields).

Any other suggestions are more than welcome.

Thanks,

Neil

you would need to use cookies, but that can still be bypassed by deleting your cookies. The other easy way would be to use a script that limits based on IP, but would would need to use a server side script, not JS.

How is this "vote" being stored?

Thanks for the info. IP is what I meant, not ISP by the way!

The votes will be sent to my email address by a form. It's real simple. My site is small and simple.

PHP is not my thing. It was hard enough doing the email php for the form.

Could you give me an idea of how complicated it would be in PHP?

Thanks again,

Neil

Here is a script that will doe what you want:
