  1. In MW 1.24+ wysiwyg will not start (#6), issue is with MW variable $styles which has been changed from public to protected variable in includes/OutputPage.php, one possible workaround requires manual modifications outside wysiwyg, other preferred one is to comment out some code lines of CKeditor.body.php manually (workaround included in Version 1.5.6_0 [B551+01.09.2015]) Github#23.
  2. Git -branch "CKeditor_v45" has updated CKeditor 4.5.1, this branch has the most recent modifications. Other branches like "master" or CKeditor_v4 etc. have older versions of CKeditor and they may not have all of the latest modifications. #6 bundle is stored in github. If you like to contribute to it, you should clone the repository of #6 in github, create new branch there for fix and finally create pull request with it, pull request will make it possible to merge patch into #6 bundle.
  3. WikiEditor has been upgraded from 0.3.0 (of MW 1.22.0) to 0.4.0 (of MW 1.23.3) in #6. Quick list of improvements is below. For more details, see readme.md here: https://github.com/Mediawiki-wysiwyg/WYSIWYG-CKeditor
  4. IE7 is not compatible, IE browsers (IE8,9,10,11) should not have any compatible settings on for your wiki site.
  5. #6 bundle of wysiwyg should be used with IE11 native mode ("Edge"), compatibility view mode should not be enabled with IE11 for your wiki site (setting is located here: "Tools=>Compatibility View settings", deselect option "Display intranet sites in compatibility view" in case your wiki is internal or remove site name from the list).
  6. FireFox v26.x - v35.x
  7. Chrome v.32.x - v.40.x

Mediawiki 1.22+ and #6 bundle of Download -section[edit | edit source]

For more information about proper settings of LocalSettings.php etc. with MW 1.22+ and #6 bundle, see README.md (on github -page).

Configuration[edit | edit source]

Customize the toolbar[edit | edit source]

Everything is explained here.

Disable for some namespaces[edit | edit source]

To disable WYSIWYG for some namespaces (for example, here Mediawiki), add the following code in your LocalSettings.php :

$wgFCKEditorExcludedNamespaces = array(NS_MEDIAWIKI);

To set default preferences while letting users chose to use WYSIWYG on certain namespaces :


To hide from preferences the checkboxes relative to the namespaces, comment these lines.

Style the content of the editor[edit | edit source]

Two solutions :

  1. Edit the file ckeditor/contents.css
  2. Point to the css file of your choice, adding this line to ckeditor/config.js :
  config.contentsCss = 'path/to/your/file.css';

Config "Paste as ..."[edit | edit source]

When clicking "Paste as..." button under Firefox, you may get a popup telling your browser can't access your clipboard. This is a security protection, but you can configure your browser so that it makes an exception for your wiki. Thus, you will be able to paste in one click, with no need to paste in the dialog field and then validate. See here.

Cleaning some tags[edit | edit source]

CKeditor functions AllowedContent and DisallowedContent are supposed to do that, but do not work. However, you can add some regexp to play this role. For example, if you don't want to allow color styles, you can add here the following lines :

data = data.replace(/\bcolor:[^;"']*;?/gi,  );

Remove advanced tab in table dialog[edit | edit source]

Add these lines in config.js :

CKEDITOR.on( 'dialogDefinition', function( ev ) {
    var dialogName = ev.data.name;
    var dialogDefinition = ev.data.definition;
    if((dialogName=='table')||(dialogName=='tableProperties')) { dialogDefinition.removeContents('advanced'); }        

Improvements[edit | edit source]

Modifications (#5 and #6 refer to Download section above)

  • Buttons to create a references (footnotes): <ref>...</ref> and <reference/> (incl. in #5 and #6)
  • Fixed Images dialog (parameters) (incl. in #5 and #6)
  • Button to add [[...]] in one click in order to convert text as target link (incl. in #5 and with additional modifications in #6)
  • Autofilling of the link dialog with selected text, and autosearch] (incl. in #5 and with additional modifications in #6)
  • Dialog to handle categories (incl. in #6)
  • [//en.wikipedia.org wikipedia] is considered as external link (incl. in #6)
  • <math> tags are not deleted anymore. Math -tags, gallery- and hovergallery- tags (HoverGallery ext.), poll- and ajaxpoll- tags (poll- and ajaxpoll ext.) as well as contents of all other unknown mediawiki tags should now be possible to enter/update using tag -dialog of wysiwyg (incl. in #6)
  • Edit text with paragraph format "Formatted" (pre- and syntaxhighlight -tags) directly as text in wysiwyg mode (skip using special -dialog). #6 Version 1.5.6_0 [B551+01.09.2015]). (Github#50, test version in branch CKeditor_v4_Nowiki-Synt-Pre)
  • Category dialog supporting hierarchical categories #6
  • Display category name in WYSIWYG beside the "C" icon (patch here, included and further modified here Version 1.5.6_0 [B551+01.09.2015]) (screenshot here)(thread here).

Possible customizations[edit | edit source]

  • Disable search for images in link dialog (incl. in #5) Question: Is this necessary modification? You can already now specify namespace as search criteria in link dialog using ":", f.ex. keying in "image:eifel" (without quotes) will search only image names starting with string "eifel". Other namespaces works similarly. Answer: Personaly, I don't use [[Media:<link>]], and I don't want images to appear in the search list of link dialog.
  • Hide checkbox "Open rich editor in a popup" in Special:Preferences : comment these lines
  • Tables :
    • summary attribute is not supported anymore in HTML5, and is of little use. I suggest to remove it
  • Remove infotip displayed on editor in wikitext view : see here
  • Image dialog enhancement (patch here) :
    • Add a button in dialog to reset to default size
    • Add a button in dialog to lock size ratio
    • Display image size by default in the dialog width/height input
    • if you type exactly the file name in the input, the image preview is loaded instantly (no need to click on the ImgList)
    • if you tick upright checkbox, the fields height and width are cleared
  • Fix a Firefox line wrap bug (patch)(thread)
  • In the image dialog, fit image preview and remove scrollbars with this css :
.ImagePreviewBox img { max-height: 200px;  max-width: 300px; }
.ImagePreviewBox { overflow: unset!important; }

Todo[edit | edit source]

Known incompatibilities[edit | edit source]

  • FileLink extension does not work with wysiwyg extension.
  • Issues with Preloader extension (#6)
    • When loading a template from Preloader, formatting may be stripped from header and thematic break tags. For example, <h3 style="font-size:16pt; font-weight=bolder; color=purple;">Title</h3> and <hr style="color:purple; width=50%; align=center;"> return only plain, black === Title === and ----, with no formatting. It is unknown whether this issue occurs with other tags, but appears likely. Github#27
  • In MW 1.24 wysiwyg will not start (#6), issue is with MW variable $styles which has been changed from public to protected variable in includes/OutputPage.php, one possible workaround requires manual modifications outside wysiwyg, other preferred one is to comment out some code lines of CKeditor.body.php manually Github#23.
