Revision [5118]

This is an old revision of DeleteSpamAction made by MovieLady on 2005-01-24 16:22:17.

 

Ok, this is the translated (with very minor additions) version of the admin action to delete spam from Wikini that GmBowen linked to on the ProgrammingHelp in RichardBerg's request for help fixing his site after a spambot attack.

I've changed all the actual variables and documentation to English, and added a couple of order by clauses to clean up the display page. Other than that, it's all his.

Caveat: I haven't been able to try this out all the way; it loads the first form (where you input the IP or username of the spammer) and the second page listing all the page revisions attributed to that IP or username just fine, but I haven't tested it any further because the only installation I have up right now is live. :\ Maybe it could be tried on the beta site?

There's no authentication to make sure it's an admin doing the deleting, so I would suggest using it only on a secured page where you're the only person with access to it, and then I'd delete the function and action page when you're done.


But hey, it's a starting point! :)

Save this as actions/deletespam.php (up to you, I suppose *g*)

                    "limit 1";
                $this->Query($makeLatest);
            }
        }
    }
    echo    "<div class=\"action_erasespam\">\n";
    echo    "Pages deleted&nbsp;: ", $this->Format($deletedPages), "\n";
    echo    "</div>\n\n";
}

?>


Ok, now in /wakka.php, you need to add the following (after backing up the file!):

         function ComposeLinkToPage($tag, $method = "", $text = "", $track = 1)
              {
                      if (!$text) $text = $tag;
                      $text = htmlentities($text);
                      if ($_SESSION["linktracking"] && $track)
                              $this->TrackLinkTo($tag);
                      return '<a href="'.$this->href($method, $tag).'">'.$text.'</a>';
              }


I added it right after where "function Link" closed and before the commented out "function PregPageLink" - it was about line 475.

So, there's the jumping off point.
