Here's my current script but it is not working.
can someone help me fix? I want it to work also regardless of uppercase or lowercase.

PHP Code:

<?php



$filtered=0; 



foreach($_POST as $val) 

{ 

echo $val;



$filtered= BadWordFilter($val); 



}  



echo "filtered:".$filtered;





function BadWordFilter($text)

{

    //fill this array with the bad words you want to filter and their replacements

    $bads =  array ("test","badword");

    

        for($i=0;$i<sizeof($bads);$i++) {            //go through each bad word

            if(eregi($bads[$i][0],$text))return 1; //if we find any, return 1

        

    

        }    

        

    }







?>





<form method=post action=testbadword.php>

<textarea name=test>

</textarea>

<input type=submit name=submit value=sumbit>

</form>

If you've got PHP 5 you can use str_ireplace()

PHP Code:

<?php



if (isset($_POST['test']))

{

    $val = $_POST['test'];

    

    $replacements = array

    (

        'test' => 'good word',

        'bad word' => 'other good word',

        'blah' => 'yeh'

    );

    

    $val = str_ireplace(array_keys($replacements), array_values($replacements), $val);

    

    echo $val;

}



?>

What exactly do you want to do? Count the bad words in the submitted text, or actually replace them?

If you only want to count them try this

PHP Code:

if (isset($_POST['test']))

{



       echo 'Matches: '. BadWordFilter($_POST['test']);

    

}





function BadWordFilter($text)

{

    //fill this array with the bad words you want to filter and their replacements

    $bads =  array ("test","badword");

    $matches = 0;

        

    foreach ($bads as $bad)

    {            //go through each bad word

        if (eregi($bad, $text))

        $matches++; 

    }

    

    return $matches;

}

thanks for your help.
I edited your version a bit but it's still not working 100%
Basically waht I want is to check for the badwords and if a badword is found I set $filtered=1
can you help me fix. I see the variable matches is changing but when I tried to set filter it's not working. what am i doing wrong?

PHP Code:

<?php



$filtered=0; 

$matches=0;

foreach($_POST as $val) 

{ 

echo $val;



//echo 'Matches: '. BadWordFilter($val); 

$matches=BadWordFilter($val); 

echo $matches;

}  



if ($matches!=0) 

{

$filtered=1;

echo "should be filtered<bR>";

}



echo "filtered:".$filtered;









       

     







function BadWordFilter($text) 

{ 

    //fill this array with the bad words you want to filter and their replacements 

    $bads =  array ("test","badword"); 

    $matches = 0; 

         

    foreach ($bads as $bad) 

    {            //go through each bad word 

        if (eregi($bad, $text)) 

        $matches++;  

    } 

     

    return $matches; 

}  



?>





<form method=post action=testbadword.php>

<textarea name=test>

</textarea>

<input type=submit name=submit value=sumbit>

</form>

Can I may ask why you're using a loop to catch the value? Why not using $_POST['test'] instead?

This sets $filtered to 1 if a bad word is found, and to 0 if not.

PHP Code:

<?php



if (isset($_POST['test']))

{

    $filtered = BadWordFilter($_POST['test']) > 0 ? 1 : 0;

    

    echo 'Filtered: '. $filtered;

}



function BadWordFilter($text) 

{ 

    //fill this array with the bad words you want to filter and their replacements 

    $bads =  array ("test","badword"); 

    $matches = 0; 

         

    foreach ($bads as $bad) //go through each bad word 

    {            

        if (eregi($bad, $text)) 

        $matches++;  

    } 

     

    return $matches; 

}  



?>

but i'm looping through all the values of the form and if any are filtered then it should be set to fitered -- will this do that?

I don't want it to go by the last form field. (in this demo there is ony one field but I will be using this on a form with many fields)

[aprogrammer]

i also want this to work if someone puts in the text box this is a test then test should be filtered. can you help me fix this?
