Puting an array in preg_match!

[Ajm113]

Ok, I am trying to get it so if preg_match see's a word in the message from the array it will show a echo. This is what I have so far:

[PHP]badwords = array("word1", "word2", "word3");
$message = $_POST['message'];

if(preg_match($ badwords, $comment))
{
echo"You posted a bad word!";
}else{

//do the rest!
}[/PHP]

Can someone sujest anyting?

preg_match doesn't allow arrays, try this:
[PHP]
$badwords = array("word1", "word2", "word3");
$message = $_POST['message'];
for($x = 0; $x < count($badwords ); $x++)
{
preg_match("/".$badwords[$x]."/", $message, $matches);
if(count($match es) > 0)
{
echo"You posted a bad word!";
}else{

//do the rest!
}
}
[/PHP]

good luck

Ok, now the script is repatedly posting a comment again and again! I have to praticly restart the table now!

I don't know what I am doing wrong. But it seems that the "for" command mite have a bug.

Here is the hole code:
[php]
$filout = array("word1"," word2", "word3");

for($x = 0; $x < count($filout); $x++)
{
preg_match("/".$filout[$x]."/", $comment, $matches);
if(count($match es) > 0)
{
echo'<div style="margin-left: 5cm; margin-top: 3cm;"><img src="lol.jpg" alt="Ha Ha!"><br>
<font color="yellow" style="arial">H a Ha, Foo! You can not spam my site!</font>
</div>';
}else{
$sql2="INSERT INTO comments(commen tTo, user, comment)VALUES( '$For', '$user', '$comment')";
$result2=mysql_ query($sql2);
header('Locatio n: index.php');
}
}[/PHP]

You put your insert inside the for loop, meaning the comment will be inserted once for every word you are trying to filter by.

Try this:

[code=php]
$filout = array("word1"," word2", "word3");
$clean = true;
foreach($fillou t as $badword)
{
preg_match("/".$badword. "/", $comment, $matches);
if(count($match es) > 0)
{
echo'<div style="margin-left: 5cm; margin-top: 3cm;"><img src="lol.jpg" alt="Ha Ha!"><br><font color="yellow" style="arial">H a Ha, Foo! You can not spam my site!</font></div>';
$clean = false;
}
}

if($clean)
{
// Do insert
}
[/code]
