Template documentation[view] [edit] [history] [purge]

This is an example of classic infobox template - a simple infobox coded as table. It doesn't rely on another, basis template, like Template:Infobox with LUA coded Module:Infobox. It also uses styles set in Template:Classic infobox/styles.css (see Extension:TemplateStyles, otherwise can be set in MediaWiki CSS pages).

The code of this template and its styles can be copied and modified by anyone to any wiki.

Overview

Table

Infobox is a table. There is two ways to build tables on wiki spaces - using HTML mark up (tags) or using wiki mark up.

Here HTML tags were used:

<table class="infobox">
   <tr><td  colspan="2" style="text-align: center; font-size:140%;">...</td></tr>
     ...
   <tr>
       <td class="ibfobox-data-title">...</td>
       <td class="ibfobox-data">...</td>
   </tr>
     ...
</table>

Wiki mark up variant:

{| class="infobox"
|colspan="2" style="text-align: center; font-size:140%;"| ...
|-
...
|class="ibfobox-data-title"| ...
|...
|-
...
|}

For more information about wiki tables see: Help:Tables.

Parameters

In all templates parameters are placed in the code with triple curly braces: {{{|}}}. Parameters can have a code name - {{{<codename>|}}}, which can be placed in any order on actual page, as long as code names are written correctly. Without code names numbers should be used instead - {{{1|}}}, and on another page template will look at the order of values filled in it.

This example infobox has 5 parameters:

title - it used to force custom text in a header of infobox

• In the code it looks like this: {{#if: {{{title|}}}|{{{title|}}}|{{PAGENAME}}}}
  • the use of #if: parser function means that parameter is optional and won't work if it's not filled
  • {{PAGENAME}} magic word in the function means that by default template uses title of the page it's used on

file - for an image file

• In the code: {{#if: {{{file|}}}|<tr><td colspan="2">[[File:{{{file|}}}{{!}}250px{{!}}center]]</td></tr>}}
  • #if: once again means it's optional, but in this case there is no default value, in other words, if no image is provided there will nothing; otherwise function adds new row in the table, which will contain image
  • wiki mark up for images sets how image will be formatted inside infobox, in this case it has fixed width - 250px, and align - center, but these values can be set up as another pair of parameters
  • only name of the file with format is needed

caption - caption under image

• In the code: {{#if: {{{caption|}}}|<tr><td colspan="2" style="text-align: center;">''{{{caption|}}}''</td></tr>}}
  • #if: - optional, without default value, otherwise adds new row in the table
  • there text formatting: style="text-align: center;" - for align, and ''...'' - to give italics to caption

prm1 - first actual data parameter, which has visible title in the infobox - "Parameter 1"

• In the code: {{{prm1}}}
  • it's very simple and there is no function - if left empty, infobox will show "Parameter 1" title, but there will be nothing to show in another column

prm1 - second data parameter, with "Parameter 2" title

• In the code:
  {{#if: {{{prm2|}}}|<tr> <td class="ib-data-title">Parameter 2</td> <td class="ib-data">{{{prm2}}}</td> </tr>}}
  • #if: again means it's optional, but if filled it will add a row with two columns

Styles

The table uses styles which determinate its look. Here we have:

• style="", most notably in the header
• and several classes
  • infobox for entire table - this wiki already has such class in Common.css page; most notably it puts the box into right side of the page and gives it background color and border
  • ibfobox-data-title - for column with data titles; will be a custom class in Template:Classic infobox/styles.css page - for educational purposes it will brighter than usual Wikipedia style
  • ibfobox-data - for second column, with data values; same as previous

Categories

With the aid of transclusion tags, infobox can place the page it's used on into a category (or several categories).

In case of this template, code:

{{#ifeq:{{NAMESPACE}}|Template|<!-- do nothing -->|[[Category:Some category]]}}

placed inside <includeonly> tag, will add the page into "Some category", unless the namespace of that page is "template" - hence "do nothing" commentary bit.

Usage

To use infobox on another page, this code must be used:

{{Classic infobox
|title =
|file = 
|caption = 
|prm1 = 
|prm2 = 
}}

Classic infobox
Description:

Per break down above, the only obligatory parameter here {{{prm1}}}.

If everything is left empty, the output will be:

Code of filled up example:

{{Classic infobox
|title = This is the title
|file = De Alice's Abenteuer im Wunderland Carroll pic 15.jpg
|caption = How far into the template rabbit hole do you go?
|prm1 = Flowers
|prm2 = Mushrooms}}

This is the title
How far into the template rabbit hole do you go?
Description:	Flowers
Links:	Mushrooms
