keyword blacklist & redirect?

Hi, short question again..

i have a rewrite rule:

RewriteRule ^([a-zA-Z0-9]+)/?$ /index.php?keyword=$1 [L] 

PHP:

The problem, some keywords i want to have on a blacklist and then redirect them to another page...

Any simple way to put such bad keyword into a blacklist?
And maybe a formfield for that?


Thanks for help,

 

You would need to use a php redirect and not an htaccess redirect to perform this. You could have the keywords in a database, text file, or just in an array.

 

So i use a header redirect? Any examples?

 

Try to create a text file that contains the keywords that you blacklist. Enter one keyword per line. Such as blacklist.txt.

<?php
$blacklist_exists = 0;
$fblacklist = fopen('./blacklist.txt','r');
while(!feof($fblacklist)){
        $current_blacklist = trim(fgets($fblacklist,1024));
        if(stristr($_GET['keyword'],$current_blacklist)){
                $blacklist_exists = 1; break;
        }
}
fclose($fblacklist);
header('location: your-new-url-location');
exit;
?>

Code (markup):

Good Luck

 

I am sorry, there is one line above that I have forgot.
