TWiki Skins

Skins overlay regular templates with alternate header/footer layouts; topic text is not affected

Overview

Skins are customized TWikiTemplates files. You can use skins to change the look of a TWiki topic, for example, the layout of the header and footer. Rendered text between header and footer does not change. You can also use skins to define an alternate view, like a view optimized for printing.

Defining Skins

Skin files are located in the twiki/templates directory and are named with the syntax: <scriptname>.<skin>.tmpl. For example, the Printable skin for the view template is view.print.tmpl.

Use the existing TWikiTemplates (like view.tmpl) or skin files as a base for your own skin, name it for example view.myskin.tmpl.

Variables in Skins

You can use template variables, TWikiVariables, and other predefined variables to compose your skins. Some commonly used variables in skins:

Variable: Expanded to:Sorted ascending
%WIKILOGOALT% Alt text of page logo
%WEBTOPICLIST% Common links of current web, defined in the WebPreferences. It includes a #GoBox
%WEBCOPYRIGHT% Copyright notice, defined in the WebPreferences
%EDITTOPIC% Edit link
%META{"attachments"}% FileAttachment table
%WIKILOGOIMG% Image URL of page logo
%WIKILOGOURL% Link of page logo
%REVINFO% Revision info, ex: r1.6 - 24 Dec 2002 - 08:12 GMT - TWikiGuest
%TOPIC% The name of the current topic
%TOPICURLENCODED% The name of the current topic, URL encoded (for form action)
%WEB% The name of the current web
%WEBURLENCODED% The name of the current web, URL encoded (for form action)
%WIKITOOLNAME% The name of your TWiki site
%REVTITLE% The revision title, if any, ex: (r1.6)
%SCRIPTSUFFIX% The script suffix, ex: .pl, .cgi
%SCRIPTURL% The script URL of TWiki
%META{"parent"}% The topic parent
%TEXT% The topic text, e.g. the content that can be edited
%META{"form"}% TWikiForm, if any

The "Go" Box and Navigation Box

The %WEBTOPICLIST% includes a "Go" box to jump to a topic. The box also understand URLs, e.g. you can type http://www.google.com/ to jump to an external web site. The feature is handy if you build a skin that has a select box of frequently used links, like Intranet home, employee database, sales database and such. A little JavaScript gets into action on the onSelect method of the select tag to fill the selected URL into the "Go" box field, then submits the form.

Here is an example form that has a select box and the "Go" box for illustration purposes. You need to have JavaScript enabled for this to work:

The ?skin=name URL parameter overrides the SKIN Preference value.
