How do I convert my "hack" to a plugin / addon???

[Dr00pY]

Ok, I have the need to hack my code so that I can regulate who uses the [ img ] tag. My code goes in the newreply.php. I still need to fully test it, and I know I still need to edit additional files to make my change complete. Just stating this, before anyone lets me know my hack doesn't work. Its not done.

Anyways.....here is what I have done....

I have inserted the following code at about line 301

        // If user primary group is not 6,7 or 17....remove the img tags
        $tmp = $vbulletin->db->query_first("
                SELECT count(1) as num
                FROM " . TABLE_PREFIX . "user AS user
                WHERE user.userid = " . $vbulletin->userinfo['userid'] . " AND
                        user.usergroupid in (6,7,17)
        ");
        if (0 == $tmp['num'])
        {

                //we need to remove the [img] tags....
                $newpost['message'] = str_ireplace("[img]","",$newpost['message']);
                $newpost['message'] = str_ireplace("[/img]","",$newpost['message']);

        }

Now lets say that was it. My whole hack was just this piece of code. How do I then move this out of the vb code and into a plugin / addon / product.

I tried looking at some examples, but most of those where template changes.


Thanks for your help,
