1. yes anoying font

2. dont restrict by ip address, according to website i only have 1 external ip address yet i have 3 pc's on my network so therefore if 3 people want to submit from the same network they cant due to being on the same ip address.

But then people could just delete the cookie :/ A good idea might be to use both, but allow the form to be used maybe 3 times by one ip, but once for each cookie...just an idea :/

true but the only proper way would be to have a user loging and keep track of if the user has posted during the current day.

It's simple...

(Toggle Plain Text)

create database restrict (
    id int not null primary key auto_increment,
    ip varchar(35),
    time timestamp
);

[php]
<?php
mysql_connect("localhost", "root", "");
mysql_select_db("");

mysql_query("delete from restrict where time >= " . time() + (24*3600));

$result = mysql_query("select * from restrict where ip =\"{$_SERVER['REMOTE_ADDR'}\"");

if(mysql_num_rows($result) == 0) {
$sql = "insert into restrict values('', '{$_SERVER['REMOTE_ADDR']}', '" . time() . "')";
mysql_query($sql);
} else {
die("You cannot access this page for 24hrs after you viewed it last...");
}

mysql_close();
?>
[/php]
