hulp nodig bij gastenboek spam

Je kan een soort 'vuile woorden' filter maken...

<?
$tekst = "dit is een vieze tekst";

$tekst = str_replace("vieze", "***", $tekst);

echo $tekst;
# dit is een *** tekst
?>

Je kan de scheldwoorden etc ook in een array stoppen voor zover ik weet ;)

Misschien heb je hier wat aan :)

Ik denk dat je meer iets in de richting van stristr() nodig hebt.

Nou ik snap er nog niet veel van, die stristr is hoofdletter ongevoelig, dus dat is wel mooi. maar wat ik dus begrijp is dat je het niet in EEN regel kunt zetten??

Die "vieze"woorden hoeft hij niet te veranderen, ik wil dat hij de comments gewoon leegmaakt : dan moet diegene lekker alles overtypen. (hetzelfde als bij "texas".
Groet fred

p.s. ik weet alleen dat php een soort computer/java taal is :(

<?php
$antiwoorden = array();
$antiwoorden[] = 'viagra';
$antiwoorden[] = 'penis';
$antiwoorden[] = 'enlarge';
//enz...

function isSpam($string){
global $antiwoorden;
$spam = false;
foreach($antiwoorden as $woord){
if(stristr($string, $woord)){
$spam = true;
}
}
return $spam;
}
?>
Nu kun je dus hetvolgende gebruiken:
<?php
if(!isSpam($_POST['comment'])){
//bericht toevoegen bij andere reacties
}
?>

edit: parameters in stristr verkeert om ^^,

Okay thnxs, zal dat even gaan uitproberen, of het gaat werken weet ik nog niet, daar jij andere variabele gebruik dan degene die in mijn script staan, maar zal wel ff proberen.
Ik laat het t.z.t wel weten of het werkt.
Groetjes Fred

Ohh, ik bega een foutje denk ik: dat gastuhbookje draait onder perl : #!/usr/bin/perl
Dat is zeker anders dan php, want dat scriptje van Jelmer krijg ik nog niet werkend :( maar dat zal wel aan mij liggen denk ik :(
Groetjes Fred

Even ter aanvulling en ter verduidelijking: het moet eigenlijk in dit script komen:
#!/usr/bin/perl

Alvast bedankt Fred

Dat lijkt inderdaad veel op PHP, maar is wel degelijk PERL. En helaas zijn er hier waarschijnlijk niet zoveel mensen die je daar mee kunnen helpen aangezien dit een website is over PHP.

Ik denk dat je dan op zoek zal moeten gaan naar een perl-handleiding en de perl equivalent van stristr (zoek string in langere string) zal moeten opzoeken.

Bedankt jelmer
ik heb nu dzperl en een perl dir op de pc, dus kan nu ff lekker klooien en testen: dan geeft hij ook meteen fouten weer: is wel makkelijk.
Dus ik zal maar ff opzoek gaan naar een perl forum :)
I.i.g. bedankt voor jullie hulp

Fred

Of je wacht even op Arend :)
Hij is onze PERL freak ^^
