"Now when processing the form... check the value of your token"
What if a user legitimately goes to your site and generates a token and then uses that token and
adds a dangerous fieldname to a static form that now has a legit token during the session?
<form name="newform" action="index.php" method="post">
<input type="text" name="potentialeveilfield" value="" size 30
/>
<input type="hidden" name="token" value="<?php echo
maketoken(newform, $userid); //$userid here could be user profile id ?>" />
<input type="submit" />
</form>
<form name="newform" action="index.php" method="post">
<input type="text" name="potentialeveilfield" value="" size 30
/>
<input type="hidden" name="token" value="9l3j34509u0ueroiu34u345"
/>
<input type="submit" />
</form>
