Please somebody tell me how to add bad word filter to php search engine

i want to add in my site <link removed>

**lynxus** · 09-09-2009, 07:40 AM

Something like:
<?php
$var = "Some nasty words";

$var= str_replace('Some nasty words','<link removed>',$var);

?>

This would replace anything in a var that says "Some nasty words" and change to "<link removed>"

Sorta like a find & replace.

What do you mean by sexy searches?

And you could use an array of bad words and replace them with an array of good words.

filter.txt

Code:

badword1,badword2,badword3

PHP Code:


			
<?php
//Input
$content = 'This is some content with a badword2 in it!';
//Take the file and put the bad words (separated by commas) in an array
$badwords = explode(',', file_get_contents('filter.txt'));
//Replace any bad words with a string
$content = str_replace($badwords, '**REMOVED**', $content);

echo $content;
?>

should I put yout filter code above form tag?? Thats what i did exactly
actually Im not a php expert. learning so slow

**stevej** · 09-19-2009, 03:06 PM

Actually, the file the code really should go in is 'video/index.php'. Play around with putting that snippet in there, and if all else fails, you can give me the code to that page.

**googledaily.com** · 09-20-2009, 03:51 AM

i uploaded the full script..below is the link

**googledaily.com** · 09-20-2009, 03:53 AM

Actually i want to prevent porn searches

Thats why Im trying to do this..
I searched alot at google to slove this, but ot of methods are through sql.

**seoconsult** · 09-20-2009, 05:15 PM

I have a readymade script if you need

**googledaily.com** · 09-21-2009, 06:16 AM

yea I really need

**stevej** · 09-21-2009, 10:28 PM

Sorry for the delayed answer - no need to post after yourself.

Go into 'video/index.php'.

Replace this code:

PHP Code:


			
<?php

if (!isset($_GET[search]) OR $_GET[search] == "") {

$_GET[search] = "muse";
include("includes/layout_main.php");

}else{
if(!$_GET[page]) {
    include("includes/searchtracking.php");
  }
include("includes/layout_main.php");

}


?>

With this:

PHP Code:


			
<?php
if (!isset($_GET[search]) OR $_GET[search] == "") {
    $_GET[search] = "muse";
} else {
    if(!$_GET[page]) {
        include("includes/searchtracking.php");
    }
}
//Make sure you have the url to filter.txt correct
$badwords = explode(',', file_get_contents('filter.txt'));
$filtered = str_replace($badwords, '', $_GET[search]);

$_GET[search] = $filtered;

//[OPTIONAL] (for testing purposes)
if($filtered) {
    echo 'It worked!';
    echo $_GET[search];
} else {
    echo "it didn't work. :(";
}
//[/OPTIONAL]

include("includes/layout_main.php");
?>

thanks, let me try.

**googledaily.com** · 09-22-2009, 03:38 PM

Thank you so much. its really working..
Its shows blank page when i enter a bad word, I wrote "waqas" in filter.txt and it worked..now all I hacve to do is, to find a huge adult keywords txt file..but im afraid that adult keywords necer ends, hehe. but we can try to reduce such things..and you really contributed to make it happen.

But your "optional" code dont work. Can we use to show a dialogue box having word "Sorry, Adult keyword are not allowed" instead of using following code??

//[OPTIONAL] (for testing purposes)
if($filtered) {
echo 'It worked!';
echo $_GET[search];
} else {
echo "it didn't work.

";
}
//[/OPTIONAL]

**googledaily.com** · 04:28 PM

well i analyze about image error. its not youtube server error. its something wrong in my script. It was showing screenshots some days ago. but it might be possible that youtube have changed something at their server

Now I need to review video/sources/youtube/yt.php again

**stevej** · 09-22-2009, 07:33 PM

Ok. To get a popup, replace this code:

PHP Code:


			
$_GET[search] = $filtered;

//[OPTIONAL] (for testing purposes)
if($filtered) {
    echo 'It worked!';
    echo $_GET[search];
} else {
    echo "it didn't work. :(";
}
//[/OPTIONAL]

With this:

PHP Code:


			
if($_GET[search] == $filtered) {
    //nothing
} else {
    echo "<script type='text/javascript'>alert('Sorry, adult keywords are not allowed.');</script>";
}

$_GET[search] = $filtered;
