Help:Templates

If you have standard texts you want to include on several pages, the MediaWiki template feature comes into play (like the tag above which is included in the pages of the Help namespace).

Creating a template
Template names are prefixed with, you create them like any other wiki page.

Using a template
Templates are wiki pages which can be used in other pages in three ways:
 * includes the content of the template at the moment the page containing it is fetched "Template:Name".
 * inserts the content of the template into the code of the page in a form that is editable normally "Template:Name" after you have saved your text.
 * when the page containing it is fetched, includes the template in a form that displays it as raw wiki syntax, like  does

Using parameters in templates
You can define parameters in templates either numbered as  or named.

Example: You want a little thank you note you can put on the talk page of other users. It will contain a reason and your signature. You could create Template:Thankyou to enter your text, as in the example in the table.

When using the template on a page, you fill in the parameter values, separated by a pipe char (|):. For named parameters use "name=value" pairs separated by a pipe char:. The advantage of using named parameters in your template is that they are flexible in order. It also makes the template easier to understand if you have many parameters. If you want to change the order of numbered parameters, you have to mention them explicitly:.

Organizing templates
For templates to be effective users need to find them and be able to use them. A simple technique is to include an example on the template page. For example:

Usage
Allows to establish a link to a subject:

Then, an editor can simply copy and paste the example to create a similar page.
