problem with templates

Hi there! Great extension. I was wondering, is it possible to call somehow fix it to work through a template? Right now if I try to use __NOCACHE__ on a template it doesn't work. Instead, it just shows the text "__NOCACHE__". Is there a way around this? Thank you!

Part Solution


I thought I fixed your problem but this is what I know so far...

It seems the text is checked before the template is processed, so only magic words on the main page is detected and not in the template. I used a different hook that will read the page after the templates has been processed.

So instead of using

$wgHooks['ParserAfterStrip'][] = array($NoCache, 'checkForMagicWord');


$wgHooks['InternalParseBeforeLinks'][] = array($NoCache, 'checkForMagicWord');

then modify the function at the end too

function checkForMagicWord(&$parser, &$text ) {

The problem is that because everything has already been processed it is too late to disable the cache :(

I hope that helps. Feel free to fix, amend or improve my solution!

Awesome! That seemed to fix it. Thanks for all of the help! Acook 21:07, 10 December 2007 (UTC)
Doesn't work here (MW 1.15). I have a <includeonly>__NOCACHE__</includeonly> in my template and the magic word is rendered in the output. Better use ParserBeforeTidy instead of InternalParseBeforeLinks
$wgHooks['ParserBeforeTidy'][] = array($NoCache, 'checkForMagicWord');

Undefined variable: action, on line 67 FIX

If you run PHP with out global variables on, you get the "Undefined variable" error.
In the function checkForMagicWord add $action to global:

 function checkForMagicWord(&$parser, &$text, &$strip_state) {
   global $wgOut, $action;
   $mw = MagicWord::get('MAG_NOCACHE');

   #woohoo! we do! - now remove the word from the text
   if (!in_array($action, array('edit', 'submit')) && $mw->matchAndRemove($text)) {

   return true;

What about work on 1.12.0?


Unexpectet behavior in templates

Nice extension. I use it in 1.13 and it seems like it works! But I want to use it in templates. When I use it in themplates, it works for the template itself but then in the pages who use the template i see the magic word IN THE TEXT as "__NOCACHE__" and it has no effect. I think the right bevior should be that it works for the pages who includes the template so that it works like it is used directly in the pages. I also tried it with <includeonly>__NOCACHE__</includeonly> in the template but I got the same effect on the page. Hope you will fix that soon. Would be very nice! Thanks -- 20:25, 18 October 2008 (UTC)

Does not work on 1.13.2

But thanks for the effort.. 14:23, 16 January 2009 (UTC)

Is it still not working on 1.13.2? Has anyone tried it? --Robinson Weijman 13:02, 28 July 2009 (UTC)
Well, I just have and it works. But - you need to put the __NOCACHE__ magic word in a hidden comment otherwise it appears on the screen. --Robinson Weijman 14:22, 28 July 2009 (UTC)
Um, or maybe not. Without __NOCACHE__ it also "works"... --Robinson Weijman 14:35, 28 July 2009 (UTC)
Using Fix for 14.x below this does work. --Robinson Weijman 09:10, 29 July 2009 (UTC)

Doesn't work on 1.15

This extension doesn't work on mediawiki svn head as of this date. -- 22:04, 14 February 2009 (UTC)

FIX for MediaWiki 1.14.x

Apparently $wgRequest is no longer invoked after editing on MW 1.14.x. I tested this on MW 1.14.0 and it works as intended (all I did was change $wgRequest to $wgAction):

function checkForMagicWord(&$parser, &$text, &$strip_state) {
    global $wgOut, $wgAction;
    $mw = MagicWord::get('MAG_NOCACHE');
    if (!in_array($wgAction, array('submit','edit'))) {

I hope this helps. Anyone wants to try this on 1.15.x ? (I don't have time to play around with the SVN version)

Works in 1.15 for me --Danwe 12:13, 7 October 2009 (UTC)

I made the same change at it works for MediaWiki 1.13.4 Wolcott 18:03, 7 April 2009 (UTC)

I made that change too and it worked for MediaWiki 1.12.0. -- 17:23, 6 July 2009 (UTC)

Works for 1.13.2 --Robinson Weijman 09:10, 29 July 2009 (UTC)

I've merged these changes into the code on this page. GreenReaper 20:49, 17 October 2009 (UTC)


put the newest version into my Wikis SVN


--DaSch 15:40, 2 October 2009 (UTC)

Why don't you add a version number to this new version and also add the code discussed above under Part Solution? --Danwe 12:21, 7 October 2009 (UTC)
