Preventing Spam

Hey,

Haven't done any PHP really but I made this script over the last couple of days and it has on it a voting system of + / - which orders the list. See below :

The problem is that it's easy for anyone to click the vote button over and over again. Is there any way of preventing this so a user/IP/computer can only vote on an entry once every hour or so?

Thanks

 

could just record the votes in a table and check if person already voted

 

There's no account system - people can vote without registering. I guess that would mean recording their IP address. Maybe have a mySQL table with the IP attached to the website they're voting on, and check that when they try to vote as well as wiping it every hour.

 

pretty much, make sure to index it as well. post_id and ip should do what you need

 

Works perfectly -- except cPanel wont stop sending me emails telling me every time it's completed a cron job
