如何在我的反馈表中制作过滤器[关闭]

Question

Some time ago I start to receive spam from the feedback form on my site.

This is my php-file

    <?
$fMail = $_POST['fMail'];
$fTitle = $_POST['fTitle'];
$fSubject = $_POST['fSubject'];
$fCount = $_POST['fCount'];
$fName = $_POST['fName'];
$fData = $_POST['fData'];
$fOk = $_POST['fOk'];
$fBad = $_POST['fBad'];
$fText="$fTitle

";
for ($i=1;$i<=$fCount;$i++) {$fText.=$fName[$i].": ".$fData[$i]."
";}
$fText.="

";
$fText.=date("l dS of F Y h:i:s A");
if (mail($fMail,$fSubject,$fText)) {Header("Location: $fOk");}
else {Header("Location: $fBad");}
exit;
?>

What can I add to this code for not receiving any more messages, including stuff like "[/url]" or "[/link]" (phpbb tags like this are included in all spam messages, that attacks my feedback form)

PS Sorry, I am not a programmer at all

PPS It will be awesome to do this without CAPTCHA, I receive only one type of spam messages (with "[/url]" and "[/link]" tags) and dont want to force my page guests to type captchas

I beleive simplest thing for you to do is to add google captcha (recaptcha) it's easy to implement and it has quiet good documentation. With it you will get rid of most spam messages. If you need help implementing it, just ask.

update:

if(strpos($fText,'[/link]') !== false or strpos($fText,'[/url]') !== false) {
if (mail($fMail,$fSubject,$fText)) {Header("Location: $fOk");}
else {Header("Location: $fBad");}
}
