Extension talk:Javascript

From mediawiki.org

The existing JavaScript.php gives a PHP warning on line 28 if there are no *.js files along with it and on line 39 if there are no *.css files along with it like:

PHP Warning:  Invalid argument supplied for foreach() in /var/www/mediawiki/extensions/JavaScript/JavaScript.php on line 28, referer: http://www.....

This is because the glob PHP function cannot distinguish between no entries and an error condition when returning false.

It can be remedied with a check to eliminate the warnings by making the file as:

<?php
/**

 *
 * @package MediaWiki
 * @subpackage Extensions
 * @author [http://www.organicdesign.co.nz/nad User:Nad]

 * Fixed Invalid argument in glob - Ap.Muthu - 2011-03-20

          }
        }
        return true;
}
Wheres the rest of this code? A PHP alway and with a ?> . But your code don't end with it.
I think it will still work without the closing php tag. I have seen many PHP source code on mediawiki without the closing tag. But I always add it before copying it to my extensions directory. 60.241.61.96 13:45, 30 September 2011 (UTC)Reply[reply]

Advantage over MediaWiki:Common.js is not clear[edit]

Could someone update the description of this extension so that its advantage over MediaWiki:Common.js is more clear? Badon 05:26, 23 November 2011 (UTC)Reply[reply]

'Undefined variable: organicdesign' error when using this extension[edit]

 I got error Undefined variable: organicdesign when using this script. Can someone please explain how to fix it?
simply write $organicdesign = ""; somewhere before the first use of the variable $organicdesign (possibly after line 23) Kappa (talk) 17:31, 4 March 2014 (UTC)Reply[reply]

Revised version[edit]

The original version of this excellent little extension has a few issues. I have added a revised version below. In it I have removed the support for Mediawiki versions 1.7 and lower since I have no way of testing the script in an old version of Mediawiki and users should upgrade to a more recent version anyway. I have also removed the support for loading stylesheets (CSS files) as this is not what the extension is about. I have edited the meta-information displayed for this extension on Mediawiki's 'Version' page. The 'organicdesign' bug referred to elsewhere has been removed.
