Avoid post flooding

[SkyRanger]

I am trying to figure out a way to stop visitors from flooding my guestbook and comments scripts.  Is there a way to do this other than using captcha.  ie: Only 1 post every 10 seconds?

Why not set a session variable with a timestamp when the user adds a comment. Then, when adding a comment use:

 

<?php

$lastpost = $_SESSION["lastpost"]; // Let's say it = 1180033452
$current = time(); // Let's say it = 1180033457

if(($current - $lastpost) < 10) {
echo "Please wait ten seconds before adding another comment";
} else {
// Process comment
}

?>
