Hi. I have just added a profanity filter to a current project which runs
like so (all form values are passed into the session after checking for
required fields etc). $swearbox is an array containing profanities so I
won't include it here!
$_SESSION['profane'] = false;
foreach ($_POST as $value) {
foreach ($swearbox as $profanity) {
if (preg_match("/$profanity/i", $value)) {
$errors = true;
$_SESSION['profane'] = true;
mail(TECHEMAIL, 'profane content attack attempt on DJST', "From:
{$_SERVER['REMOTE_ADDRESS']} Time: " . date('d F Y G:i:s', time()-TIMEDIFF),
'[EMAIL PROTECTED]');
}
}
}
...if $errors is true at the end of processing I send the user back to the
form. In this instance if there are rude words $_SESSION['profane'] is set
and we warn the user.
