First a warning, I am new to php and mysql, what I did was mostly trial and trial and trial and lots of errors - so if you find redudant code or you have suggestions for improvements , please tell me!

What does it do?

This hack of mine gives the users the possibility to mark pageupdates as minor changes (typos etc.). I also wrote an action called "recentmajorchanges" which allows the user to see only major, only minor or all changes during a number of days.

What has to be changed?


Known Issues

the handler "clone" throws a warning. Just add a ",0" to the SavePage(...) function call, i.e.
$this->SavePage($to, $pagecontent, $note,0); #create target page.

I don't know if there are calls to SavePage anywhere else. If so, these actions etc. will also throw a warning, but they should work despite the warning.

to do



Change to the MYSQL Database


As a fist step you have to add a cell to the table "pages" in the MYSQL Database called "minorchange", which consists of a boolean value. FALSE or 0 meaning "no minor change", TRUE or !=0 means "minorchange"

the MYSQL Query is:
ALTER TABLE `wikka_pages` ADD `minorchange` BOOL NOT NULL DEFAULT '0';

NOTE: I'm assuming you use the standart table prefix wikka_ here!



The PHP Code


Changes in /libs/wakka.class.php


SavePage
The function SavePage in /libs/wakka.class.php has to be altered to be able to save the minorchange flag. inserted lines are commented
    function SavePage($tag, $body, $note, $minorchange) //editet by FishPete
    {
        if (!isset($minorchange)) $minorchange='0';// inserted by FishPete; if SavePage is called without the $minorchange parameter, assume no minorchange and continue
    // get current user
        $user = $this->GetUserName();

        // TODO: check write privilege
        if ($this->HasAccess("write", $tag))
        {
            // is page new?
            if (!$oldPage = $this->LoadPage($tag))
            {
                // current user is owner if user is logged in, otherwise, no owner.
                if ($this->GetUser()) $owner = $user;
            }
            else
            {
                // aha! page isn't new. keep owner!
                $owner = $oldPage["owner"];
            }

            // set all other revisions to old
            $this->Query("update ".$this->config["table_prefix"]."pages set latest = 'N' where tag = '".mysql_real_escape_string($tag)."'");

            // add new revision
            $this->Query("insert into ".$this->config["table_prefix"]."pages set ".
                "tag = '".mysql_real_escape_string($tag)."', ".
                "time = now(), ".
                "owner = '".mysql_real_escape_string($owner)."', ".
                "user = '".mysql_real_escape_string($user)."', ".
                "note = '".mysql_real_escape_string($note)."', ".
                "latest = 'Y', ".
                "minorchange = ".$minorchange.", ". // inserted by FishPete
                "body = '".mysql_real_escape_string($body)."'");
      if ($pingdata = $this->GetPingParams($this->config["wikiping_server"], $tag, $user, $note))
                $this->WikiPing($pingdata);
        }
    }


ChangedDuringLastDays

I wrote a function to display changes during the last days to be used instead of LoadRecentlyChanged() Just insert it right after the function LoadRecentlyChanged()

 /*$interval: number of days which should be displayed
  * $show: whether to show all, only major or only minor changes  
  * returns array of pages which were changed during the last ($interval) days and are according to $show criteria
  */

       
function LoadChangedDuringLastDays($interval, $show)
    {
    switch ($show)
    {
      case 'all':
        $param=''; //no additional parameter in the MYSQL Query
        break;
      case 'major':
        $param='AND minorchange = 0'; //to be used in the MYSQL Query
        break;
      case 'minor':
        $param='AND minorchange !=0'; //to be used in the MYSQL Query
        break;
    }
    if ($pages = $this->LoadAll("select * from ".$this->config["table_prefix"]."pages where time> DATE_SUB(now(),INTERVAL ".$interval." DAY) ".$param." order by time desc"))
        {
          foreach ($pages as $page)
            {
                $this->CachePage($page);
            }
            return $pages;
        }
    }




Changes in /handlers/page/edit.php


The next thing to do is add a checkbox to /handlers/pages/edit.php which allows the user to mark a change as a minor one. Since the little code changes are all over the place in this file I'll post the whole file on MinorEditHackEditPHP. The lines I changed are commented with " edited by FishPete. Just search for FishPete in the file and it should take you to the new lines.
29.6.06: I just added a line to edit.php to show the checkbox during "preview mode". -FishPete




The action RecentMajorChanges


This file is mainly the action recentchanges which I altered a bit. Save this code as /actions/recentmajorchanges.php
I took out the user specific maximum of changes to show, but its easy to take it back in. just un-comment the lines .
Pages which were edited twice appear twice in the list. That's a feature, not a bug ;-)
