== 1. Overview ==
|
|
|
|
|
|
|
|
|
|
The MathCaptcha plugin is an alternative captcha[1] mechanism which can
|
|
|
|
|
be used in conjunction with the ConfirmEdit extension[2] to provide a
|
|
|
|
|
more convenient means of blocking or throttling automated editing.
|
|
|
|
|
|
|
|
|
|
The method used to generate the captcha images, and the formatting of
|
|
|
|
|
said images, means that the captchas will not, at this time, defeat a
|
|
|
|
|
tool which is designed to break them; however, casual mass-registration
|
|
|
|
|
or mass-spamming attempts will be dissuaded.
|
|
|
|
|
|
|
|
|
|
== 2. Requirements ==
|
|
|
|
|
|
|
|
|
|
The plugin requires
|
|
|
|
|
|
|
|
|
|
* Working support for TeX within MediaWiki (using the standard TexVC
|
|
|
|
|
software)[3]
|
|
|
|
|
* ConfirmEdit extension
|
|
|
|
|
|
|
|
|
|
== 3. Installing the plugin ==
|
|
|
|
|
|
|
|
|
|
Check the plugin out from Subversion[4] (and check out the ConfirmEdit
|
|
|
|
|
extension, if you don't have it installed) and place the files in your
|
|
|
|
|
extensions/ directory, within your wiki root.
|
|
|
|
|
|
|
|
|
|
Edit LocalSettings.php and add the following lines near the bottom of the
|
2009-12-05 15:03:20 +00:00
|
|
|
file, above the closing ?> tag, if any:
|
2006-06-12 19:56:17 +00:00
|
|
|
|
|
|
|
|
require_once( 'extensions/ConfirmEdit.php' );
|
|
|
|
|
require_once( 'extensions/MathCaptcha.php' );
|
|
|
|
|
$wgCaptchaClass = 'MathCaptcha';
|

|
|
|
|
2006-06-12 19:56:17 +00:00
|
|
|
This installs ConfirmEdit and instructs it to use the MathCaptcha plugin.
|
|
|
|
|
The default settings for ConfirmEdit are used. At this point, no further
|
|
|
|
|
action is required to have the plugin work for user registration or edits
|
|
|
|
|
which add new external links to a page.
|
|
|
|
|
|
|
|
|
|
== 4. Customising captcha behaviour ==
|
|
|
|
|
|
|
|
|
|
A number of settings relating to the ConfirmEdit extension can be used to alter
|
|
|
|
|
the attitude of the captcha, including those actions for which it appears,
|
|
|
|
|
users who do not have to pass a captcha, etc. See the ConfirmEdit.php file for
|
|
|
|
|
information on this.
|
|
|
|
|
|
|
|
|
|
As an example, to throw a captcha for all edits, add the following line to
|
|
|
|
|
LocalSettings.php:
|
|
|
|
|
|
|
|
|
|
$wgCaptchaTriggers['edit'] = true;
|
|
|
|
|
|
