Error on cindy extension

Hi, I created a wiki about mathematical proofs and I tried to install the cindy extension. However, there is any error on line 62:

   $file = Image::newFromName( $appletBinary ) ; // Get the Image object from the file name

I would like to know if there is any way to fix this. Best regards, Brunner Nathan

Hi, Brunner Nathan,

I am sorry but Cindy extension is very outdated, last version from April, 2009. Meanwhile the syntax of MediaWiki software changed a lot. It would be the best to write a new extension from scratch. By the way, a new version of the GeoGebra extension will be assembled by a member of the GeoGebra team (hopefully soon).

I found you at googleplus and added you to my "Bekannten" (maybe, "my well-known persons" in English). Please send me an email at googleplus, so I can give you more specific information.

Mediawiki 1.18 error

Hi, there seems to be a little problem with the GeoGebra extension in Mediawiki 1.18 (which I just installed on wikiskola.se). I am not skilled enough a programmer to sort it out but the error origins in line 61

$imgFile = Image::newFromName($imgBinary);

I know from the extension embedPDF that the class Image is excluded in version 1.18 so that may be a clue to fix it. I hope that I could be of some help.

This workaround should have fixed the problem: Extension:GeoGebra#Change_from_2.7g_to_2.7h --Rudolf.Grossmann (talk) 17:31, 23 February 2012 (UTC)

MIME-types

Hi,

for your GeoGebra-extension it is possible to keep $wgVerifyMimeType to true. For this you must only add the GeoGebra (*.ggb) MIME-type to the check list of MediaWiki.

1. You must add the following line to the define('MM_WELL_KNOWN_MIME_TYPES' in includes/MimeMagic.php:

application/vnd.geogebra.file ggb

2. Add the following line to the end of the file includes/mime.info

application/vnd.geogebra.file [OFFICE]

Now MediaWiki knows the GeoGebra-MIME-code. --89.244.122.159 08:42, 22 September 2011 (UTC) - ChrissW-R1

Broken link

Hi!

I was trying to install the GeoGebra extension but the link to http://www.geogebra.org/webstart/unsigned/unpacked/ is broken. I got: Error 403. Denied access

How can I download that files? Thanks in advance... Helder 18:39, 6 March 2010 (UTC)

I have no problem with downloading e.g. geogebra.jar from http://www.geogebra.org/webstart/unsigned/unpacked/

Maybe trouble with protection software? At my school we have problems with dansguardian. See also personal mail.

Avoiding errors in error log

From apache error log

[Thu Mar 11 20:18:45 2010] [error] [client 10.41.3.15] PHP Notice: Undefined index: substimage in /var/www/html/cats/extensions/GeoGebra/GeoGebra.php on line 81, referer: ...

This can be avoided by replacing these three lines

$imgBinary = htmlspecialchars(strip_tags($args['substimage']));

$useSignedJar = $args['usesignedjar'];

$useLocalJar = $args['uselocaljar'];

with something like

$imgBinary = isset($args['substimage']) ? htmlspecialchars(strip_tags($args['substimage'])) : '';

$useSignedJar = isset($args['usesignedjar']) ? $args['usesignedjar'] : '';

$useLocalJar = isset($args['uselocaljar']) ? $args['uselocaljar'] : '';
