Question about external links coding

[samergains]

Hi everyone,
I'm trying to modify the file includes/class_bbcode.php to make the external links coded.
I added a block of code to the function called handle_bbcode_url

PHP Code:

$coding_needed = true;

        if (!isset($current_url))
        {
            $current_url = @parse_url($this->registry->options['bburl']);
            $current_host = preg_replace('#:(\d)+$#', '', VB_HTTP_HOST);
            $allowed = preg_split('#\s+#', $this->registry->options['url_nofollow_whitelist'], -1, PREG_SPLIT_NO_EMPTY);
            $allowed[] = preg_replace('#^www\.#i', '', $current_host);
            $allowed[] = preg_replace('#^www\.#i', '', $current_url['host']);
        }

        $target_url = preg_replace('#^([a-z0-9]+:(//)?)#', '', $rightlink);
if(isset($allowed))
            {
        foreach ($allowed AS $host)
        {
            if (stripos($target_url, $host) !== false)
            {
                if ($this->registry->options['url_nofollow']) {
                    $is_external = false;
                }
                $coding_needed = false;
            }
        }
        }
        

        if ($coding_needed && preg_match('~^https?://~i', $rightlink)) {
            $t = $rightlink;
            $rightlink = '/forum/outgoing.php?to=';

            for ($i = 0; $i < strlen($t); $i ++) {
                $rightlink .= dechex(ord(substr($t, $i, 1)));
            }
        } 

it's working fine but the problem is that it's coding all the link not only the external ones. the parameter coding_needed is always true.

how can I fix that?

thanks in advance for any ideas.

I looked at it and can't see anything offhand, but what I usually do is print out some debug info using print_r(), maybe to a file. If you look at $allowed and $target_url I'm guessing that you'll see the problem.
