I've made a few changes here:
- using $wgScript instead of $_SERVER values - this works if the wiki is installed in a subdir
- a few other cleanups I found necessary to get it to work on 1.6.3
- using "action=purge" in the last/next month links. This takes care of caching, though it isn't perfect.

Bugs[edit]
Not sure what this bug is[edit]
I use the modified code, because my wiki is in a subfolder of my domain,
but <anything></anything>, nowiki, task etc give me something like that
UNIQ1278c00d130ff9b6-nowiki63155acb276802d00000002
Same problem with the original code.
Documentation Bug[edit]
The comments at the top of the file are incorrect. The correct usage is:
<calendar>7 2006</calendar>
Note the ' ' in the explode() call and the '-' in the comments, need to change one or the other.
Next/Previous buttons[edit]
I had to modify line 177 like this to make those work:
$currentpage .= $params[$i]."&";
Otherwise the URL looked like this :
index.php?title=Accueilaction=purgemonth=7&year=2006
also needed to modify line 181
$purge="";
Prev/Next month buttons work only when logged[edit]
Prev/next month buttons work fine when the user is logged (no need of sysop status). But when the user is not logged, they lead to a page asking for a confirmation for purging the cache then go back to the main page with an unchanged month.
Comment: Thats not true, im logged, and even they dont work.
Pretty looking[edit]
Hi, how did you manage this pretty looking calendar (your png image, so nicely framed? Can I ask how you achived all this? Thanks! Guy
Hi,
I use the default theme monobook and didn't change much at all: in skins/monobook/main.css I added
.calendarEventTitle a{
font-weight: bold;
}
div.calendarEventContent{
padding-left: 12px;
}
table.calendar, table.calendar td{
border-style: solid;
border-width: thin;
border-color: #AAAAAA;
text-align: center;
}
that should do it?
Peter
Yes this did it! Now the calendar looks good, thanks so much! Guy
Windows Adjustment[edit]
REQUEST_URI not defined on Windows systems, change to PHP_SELF. --Julie 18:12, 6 July 2006 (UTC)
Patch to work with mediawiki 1.7.0[edit]
To do calendar_extension_extended working with mediawiki 1.7.0 I had to patch calendar. I used the version taken from this discussion.
At line 220/221 I had to change
$article = new Article( $title ); $articleContext = getPreloadedText( $articleName );
to
$article = new Article( $wl_title ); $articleContext = getContext( $article );
First line will define the article, $title isn't declared. Second line gets the context of the article, getPreloadedText is not available in 1.7.0 (deprcated?).
Works fine, but if the content contains links like
[http://www.externallink.tld this is an external link]
it will be shown like using nowiki-Tags. Anybody any idea?
Dischneider 18:06, 11 July 2006 (UTC)
After applying all the patches this script only works halfway for me with 1.7.0. In particular:
- cannot change month (url pattern called on click is like ".../index.php?title=Sandboxaction=submitaction=purge&month=8&year=2006")
- list of events does not show up below calendar
--Eric Pichon 19:56, 11 July 2006 (UTC)
Patched again[edit]
Due to some errors I patched calendar_extension_extended again. Now, the described function next and previous month is working well. As addon I changed the function to show the calendar to mark the actually date only in current month and year as today. With the old extension every "today" in every month and every year were be marked. You can see it working at http://wiki.wemelug.de - please don't put any event without relevance to wemelug into, it's not an testing system!
Additional minor changes: link to existing date-pages are no longer in edit mode.
Here comes my complete script, thanks a lot

One more patch[edit]
Even the above code contains a small bug.
In
function createmwCalendar()
the following line (it's line 49)
$input = ($_GET['month']<10?"0":"").date($_GET['month']." ".$_GET['year']);
should probably read:
$input = ($_GET['month']<10?"0":"").$_GET['month']." ".$_GET['year'];
Only display a headline under the calendar.[edit]
I used Dischneider's script, but changed a few lines, because I wanted to show just a heading under the calendar. -Trond
$articleContent = $article->getContent();
// get title
// == The first title like this ==
// will be the text under the calender
// == Can also be breaked<br>Like this ==
ereg("(\== )([^==]*)(.*)", $articleContent, $articleContentOut) ;
// $revision = Revfision::newFromTitle($wl_title);
$viewEvents .= "<p class=\"calendarEventContent\"><a href=\"http://".$_SERVER['SERVER_NAME'].$wgScript."?title=$articleName\">".$articleName."</a><br />".$articleContentOut[2].'</p>';
next - previous month doesn't works[edit]
if you're not logged it ask for you to purge or not, same probleme with IE and FF version 1.6.8. And if you have some event recorded in a day, when you click on this day (in the calendar) it display you the edit pahe, and not the daily page (in readable version)
thanks for all
Solution[edit]
Day of week - monday first?[edit]
To have monday instead of sunday first day of week, you need to add some code.
This is what the code looks like when it works:
var $wday_names = array("Ma","Ti","On","To","Fr","Lø","Sø"); // put sunday first to change order of the days
and
$weekday_number_b = (($day - 7 * floor($day / 7))); //
if ($weekday_number_b == 0) {
$weekday_number = 6;
}
else
{
$weekday_number = ($weekday_number_b - 1);
}
return $weekday_number;
}
On the first version of this code, months when first day of month was sunday, went wrong.
Change Article Name to German/European Data Format -> dd.mm.yyyy[edit]
edit
$articleName = $this->year."-".$this->month."-".$dayNr;
to
$articleName = $dayNr.".".$this->month.".".$this->year;
Adding an Entry Error[edit]
I'm running mediawiki 1.6.8. If I click on a date to add an entry, it tries to go to the index.php page but it tells me:
The requested URL /index.php was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
- see below -tb
Version 1.8.2[edit]
Is there a version or calendar that functions correctly with WM 1.8.2?
I tried all of the variations mentioned here in the discussions, and can not get the month change to work, nor the year to change.
Thanks.
edit: apologies, with the initialization of the calendar without any date (eg <calendar></calendar>, not <calendar>11 2006</calendar>) it works as it should.
Much thanks.
Updates that I need[edit]
I use 1.8.2 with variables in the URL. Therefor I need to update the Script: Line 234 to:
$viewEvents .= "<div style=\"padding:10px\"><a href=\"http://".$_SERVER['SERVER_NAME'].$wgScript."?title=$articleName\">".$articleName."</a><br />".$articleContent.'</div><br>';
otherwise the URL is wrong and it links to index.php
additional there is a mistake in line 83 with März (for the german)
März-- de:the0bone

Mediawiki 1.9.2[edit]
I am using the patched for 1.70 version above on MediaWiki 1.9.2 and have tried using <calendar></calendar> as well as <calendar>02 2007</calendar> as also suggested above.
I get the following error: �UNIQde5ccdf26a49ab0-calendar-00000002-QINU
Does anybody know a fix for this? Many thanks.
COMMENT: Hi, I am using Mediawiki 1.8.3 and I get a similar error when using two calendar-tags on the same article page. I also get this kind of error when using the CategoryTree extension on the same article page. So maybe try using the calendar-tag only once (since nowiki-tags don't seem to work either), or without any other tag-based extensions. Hope this helps (I know it probably doesn't) ;o) -- Tri
COMMENT: Using 1.9.2 I have the same problem. Me for 1.9.3 aswell.
Fixed! The code in the article has now been fixed so that it works with 1.9.2 etc. Micrology 19:41, 6 May 2007 (UTC)

Hey - I have replaced the code of "function dayOfWeek" to this one:
function dayOfWeek($month,$year) {
return date("w",mktime(0,0,0,$month,1,$year));
That's all!
How easy it is... And it starts with Sunday, not Monday.
I'll make some more patches, probably, and post them here. Peleg 11:01, 14 May 2007 (UTC)
Is there a simple code like this one to start on Monday ?

The Next/Previous Button is not working.[edit]
My calendar is showing but the next month/previous month button is not working. I'm logged in as the admin. please help me out on this.
my code is:
<?php
# Calendar Extension
# Creates a calendar of the month and year.
#
# Example Code
#
# <calendar></calendar>
# this defaults to "current month"
#
# (I guess you can still use <calendar>2005-05</calendar> as well, in that case you won't be able to jump to next mont)
#

# patched for working with wikimedia 1.7.0 by Dirk Schneider info _at_ dischneider _dot_ de
#
# 2006-07-12
# patched to show "today" marked only in current month and current year
# patched to work with mw 1.7.0
# patched to let links to previous and next month work
#
# 2007-05-12
# patched to call the Parser in a way that works on 1.9.2+ by Nigel Gilbert n.gilbert_at_surrey.ac.uk
