The **Template** [[Help:WikiPlugin|plugin]] allows to include text from a wiki page and replace certain placeholders by parameters.

A template can be seen as a parametrized block. It is similiar to [[CreatePage]] with the template argument, but at run-time.

There are two syntaxes to call a template, the usual Phpwiki syntax for plugins, and a more
concise syntax similar to Mediawiki templates.

== Usage ==

=== Without parameters ===

Plugin syntax:
{{{
<<Template page=Footer>>
}}}

Short syntax:
{{{
{{Footer}}
}}}

=== With parameters ===

Plugin syntax:
{{{
<<Template page=Film vars="title=SomeFilm&year=1999">>
}}}

Short syntax:
{{{
{{Film|title=SomeFilm|year=1999}}
}}}

=== With a specific revision of the page ===

Plugin syntax:
{{{
<<Template page=somepage rev=5>>
}}}

Short syntax:
{{{
{{somepage?version=5}}
}}}

== Arguments ==

{| class="bordered"
|-
! Argument
! Description
! Default value
|-
| **page**
| pagename to be included as template
| //None// (required argument)
|-
| **vars**
| optional parameters to be expanded inside the template
| (empty)
|-
| **rev**
| page revision
| most recent revision
|-
| **section**
| just include a named section
| (empty)
|-
| **sectionhead**
| when including a named section show the heading
| (empty)
|}

=== Page to include ===

If "Template:$page" exists, it is used.

Else, if "Template/$page" exists, it is used.

Else "$page" is used.

This allows compatibility with Mediawiki that puts templates in the "Template:" namespace.

=== Parameter expansion ===

We only support named parameters, not numbered ones as in Mediawiki, and
the placeholder is %%var%% and not ~{~{~{var~}~}~} as in Mediawiki.

{{{
vars="var1=value1&var2=value2"
}}}

The following predefined variables are automatically expanded if existing:
{| class="bordered"
|-
! Variable
! Description
|-
| pagename
|
|-
| mtime
| last modified date + time
|-
| ctime
| creation date + time
|-
| author
| last author
|-
| owner
|
|-
| creator
| first author
|-
| SERVER_URL
|
|-
| DATA_PATH
|
|-
| SCRIPT_NAME
|
|-
| PHPWIKI_BASE_URL
|
|-
| BASE_URL
|
|}

== Inclusion ==

~<noinclude> .. ~</noinclude> is stripped.

~<includeonly> .. ~</includeonly> is only expanded in pages using the template, not in the template itself.
