How to know referrer on a form POST submission?

mholt · 10-29-2005, 01:15 PM

Hi! ^_^

Suppose somebody submits a form via POST - how do I check the referrer so that I know the form actually came from MY SITE ONLY and not a remote server (this is used to prevent hacking, it's a good security measure)

Thanks,

getenv('HTTP_REFERER') ?

But the referer can be faked so don't rely on it alone and always check form submissions etc
