Extension:Tasks Extension

This extension provides the ability to create tasks on any page of your MediaWiki. Tasks may have severity, priority, status, and owner properties set. Also included is a highly configurable Special page for aggregateing tasks on your site by various criteria. All tasks are stored in MySQL, so the Special page is extremely fast.

Original author is Aran Deltac, but he no longer maintained it. I don't guarantee that I'll maintain this extension, but I write here all necessary to make it work, 'cause Aran Deltac only propose the archive to download. Fortunately google cache gave me instructions to make it work! --Iubito 15:54, 10 February 2006 (UTC)

Compatibility
Aran Deltac has tested it on MediaWiki 1.5.1, Iubito tested it on MediaWiki 1.4.14 (as of version 0.4). User:Smilner could not get it to work out of the box on 1.5.6. Use at your own risk.

Version 0.4.3
1. Change the SQL code that makes the tasks table as create type task_status as ENUM('!','1','2','3',' ','x'); create type yes_no as ENUM('y','n');
 * Working on 1.5.8 for James.
 * Working on v1.15.2 for Carl. I am running PostgreSQL v 8.3.12.  Several minor modifications were needed to port this from MySQL to Postgres

CREATE TABLE tasks (   page_id INT NOT NULL DEFAULT 0,    STATUS task_status NOT NULL DEFAULT ' ',    owner varCHAR(255) NOT NULL,    summary text NOT NULL,    hidden yes_no NOT NULL DEFAULT 'n' );

create index owner_idx on tasks (owner); 2. Conform 3 lines of SpecialTasks.php to convert double quotes to single quotes in where clause. Change line $where[] = 'status<="'.$args['status'].'"';

to $where[] = 'status<='. "'". $args['status']."'";

and $where[] = 'owner="'.$args['owner'].'"';

to $where[] = 'owner='. "'" . $args['owner']. "'";

and $where[] = 'hidden="n"';

to $where[] = 'hidden='. "'n'";

3. My system is case sensitive. Tasks.php code did not match the image names and I liked the image hack by tbhot3ww anyway, so I changed Tasks.php formatTask function line. You could just as easily change the image names too.

From $img = '<img src="'.$wgScriptPath.'/images/task';

to $img = '<img src="'.$wgScriptPath.'/images/Ntask';

 * replaced &$parser by $parser in Tasks.php and it seems to fix the previous mentionned error message -- Eric Lacroix 13:53, 12 November 2011 (UTC)

Usage
Each task must be on its own line and start with [ ]. All the tasks must be grouped with a ..

[ ] Regular task (Owner User) [1] High priority task. [2] Medium priority task. [3] Low priority task (Owner User) [!] Urgent task (must be completed immediately!!!) (Owner user). [x] Closed task.

According to the regular expression, owner parsing doesn't work when there is anything, even a space character, after ')'. e.g.  [ ] Regular task (Owner User)  works fine, but  [ ] Regular task (Owner User).  (note the trailing dot) does not work right.

The tasks tag may have an optional parameter, called hidden, which hides the tasks from being viewed. To use it you would write the beginning tasks tag like.

Tasks Special Page
This page finds all tasks on all pages of your site and displays them all on one page. To view all tasks access index.php?title=Special:Tasks (or Special pages » Tasks). You can provide several arguments to limit the tasks that are returned.
 * status - Show all tasks with the specified status or higher. So, specifying "status=2" would include tasks with the status codes 2, 1, and !.
 * owner - Only tasks assigned to this user.
 * limit - Number of total tasks to list.
 * hidden - Enable the display of hidden tasks.

These arguments are specified by adding a / after and adding them as regular name/value pairs.

Installation
Copy/paste the following codes in files.

includes/SpecialTasks.php
You can restrict access to the page by replacing in the source by This will restrict the access to the users with the "onlyuser"-right. If 'onlyuser' is not a naturally available right in MediaWiki (i.e. not listed on User_rights), When you go to the SpecialPages as a user with 'onlyuser' right, the Tasks link should appear at the bottom under Restricted special pages (tested on 1.6.5). See also Preventing access to some SpecialPages. --Dangerville 22:14, 24 June 2006 (UTC)
 * 1) add 'onlyuser' to the available rights with this line in  :
 * 2) add this line in   (replace 'user' with any other defined user group you want to give the 'onlyuser' privilege):

Execute SQL
If you are using a prefix on your tables, replace PREFIX_ with your prefix. Otherwise you should create a table just named 'tasks'.

Images
Right click and save these images into your images/ folder (image names should be lowercase).



Images hack by tbhot3ww
This are another images you can use in your todo



In order to work as expected modify file Tasks.php and change this line in formatTask function

with this line

LocalSettings.php
At the end of LocalSettings.php, add : include("extensions/Tasks.php"); include("includes/SpecialTasks.php");

All done !
