[Help] IP Logging

[devxtec]

I'm slightly new to php and I've been looking all over for tutorials on how to do what I'm trying to do and haven't found anything yet.

I'm trying to take a contact form I made using php and make it so that it will only allow a visitor the ability to fill out the form and send it once every 15 minutes. How can implement this using php?

in the form that teh user fills in have...

<input type="hidden" name="IPADDY" id="IPADDY" value="<?php echo $_SERVER['REMOTE_ADDR']; ?>">

now on submission of the form have a table to log ipaddy and the time...

$query = mysql_query("INSERT INTO `iplog` (`ipaddy`,`time`) VALUES ('" . $_POST['IPADDY'] . "', '" . mktime() . "');

before you add that line query the table for that ipaddress and se if the corresponding time is > (mktime() - (60 * 15)) if it is they tried less than 15 mins ago so display a message telling thme so. If not process the formand add that info to your log table.

Not a good idea to pass the IP from the form. Someone could easily create a form on their desktop that passes anything they want to your page and still spam it. Better to obtain the IP address from $_SERVER['REMOTE_ADDR'] on the page that processes the form or use sessions.
