Wiki Template System[edit | edit source]

See the handbook for full details; the local Help:Templates article covers essentials as does the Quick Guide on meta See wp:Wikipedia:Template_messages for info about the templates used in the wikipedia project.

Templates are a system for streamlining the data entry and display formatting of article content.

Unfortunately, despite (old) efforts like 'Global Bits and Pieces' or Global Wiki, Global Templates, MediaWiki software does not come with bundled templates. There is no 'package' or 'Starter Kit' of useful templates. Each wiki is left to create their own. Although you could export and import templates from say mediawiki.org, you would end up with a huge amount of Lua modules and template code that would be overkill for any regular use case. Global Templates was mentioned in the 2020 Community Wishlist under 'miscellaneous' -> 'translate templates' [1] but it's not an exact match, and likely won't be adopted anyway. Still, there are at least a couple 'Phabricator' issues related to Templates: https://phabricator.wikimedia.org/T121470 https://phabricator.wikimedia.org/T243150

Types and Examples[edit | edit source]

Presentation and Data Entry[edit | edit source]

A simple example of this is the Wikipedia article on the rock band 'U2'. This article and all Wikipedia articles about musical groups use a "Infobox musical artist" template so authors can record the basics about the musical artist: Band name, discography, genre, albums etc., AND that information can be systematically formatted for display in the article.

Navigation for a collection of content[edit | edit source]

example of a Navigation Panel

For example, Navigation Event Platform (see right) is a template that provides a navigation panel with a search box plus links to all the most important documentation related to the "Event Platform". It is simple to edit this navigation panel, create sub-sections with headings, add an image for branding, etc.

Functional Templates[edit | edit source]

Templates can also be used to include functionality in a page. An example of this is to mark a page, or link to another application systematically based on either a variable, or a "magic word" like PAGENAME More on MediaWiki variables is at meta:Help:Variable

Static Templates[edit | edit source]

Templates can also be used to include static content on a page (kind of like a keyword macro). This is useful when you want to mark a bunch of pages with some common message content, e.g. 'obsolete', 'stub', 'needs attention' etc.; or perhaps you have a collection of articles that you want to apply a common resource box or navigation to.

Using Templates[edit | edit source]

  1. (optional) create a new page
  2. insert the template marker in the page content e.g.

{{my footer}} would use the 'my footer' template on a page

  1. (optional) save and re-edit the page as needed to fill out a data entry template

Templates that are data entry templates (having multiple parameters) will have (by convention) a 'noinclude' section found in the template that gives an example which makes it a simple matter of copy and paste to begin using that template.

Available Templates[edit | edit source]

See all templates in the prefix index (choose the 'Template' namespace in the select box, then press 'Go')

Debugging Templates[edit | edit source]

You can add action=raw&templates=expand to the end of a page URL to see the raw wikitext as

The "transclusion" idea is similar (and shares the same basic syntax) allowing you to include other article content by inclusion.

Programming with Template Systems[edit | edit source]

There are many templating systems in use throughout technology platforms. In fact, any server-side processing technology like PHP offers a built-in notion of templating for separating your display from your business logic and your data using 'includes'. Carried further, there are major templating sub-systems, template libraries, and/or programming frameworks that utilize a particular templating strategy.

Smarty[edit | edit source]

For PHP programmers, one of the oldest and well-known template systems (aside from building your own using includes) is the Smarty system. For a quick overview, see wp:Smarty There is also a crash course on the Smarty website in addition to the documentation

Smarty in CiviCRM[edit | edit source]

As of Feb. 2016, Civi uses Smarty v2

Something like this little one-liner can help to generate your Smarty captures if you have a long list of custom variables

php -r 'include ("/var/www/equality-tech.com/www/drupal/sites/all/modules/custom/eqt/eqt.module"); $stack="stats"; $vars = getHaystack($stack); foreach ($vars as $k=>$v) {print "{capture assign=$k}{{$stack}.$k}{/capture}\n";};';
