PHP: Form Mail

Posted: Sat Dec 07, 2002 10:26 am (21 years, 4 months ago)

I have created a form mail script that uses the mail() function to send me feedback off my site. I was wondering if anyone could tell me howto make it so that the same IP address can't send again with the form until 30seconds has expired. This is to prevent spamming.

Well you'd have to log the IP of the person in a database or in a text file. However, none of this would be foolproof, as sometimes you won't be able to get the IP, or you'll get an IP for a cache... Confused

Apart from what Daniel suggested, try using the image thing. Ask the person to type in the code that is given in image generated dynamically each time. That way you can avoid robotic spamming Smile
