+## Using a template
+
Using a template works like this:
- \[[template id=note text="""Here is the text to insert into my note."""]]
+ \[[!template id=note text="""Here is the text to insert into my note."""]]
This fills out the [[note]] template, filling in the `text` field with
the specified value, and inserts the result into the page.

-To create a template, simply add a template directive to a page, and page will

-The template uses the syntax used by the

-perl module, which allows for some fairly complex things to be done.

+
+* Each parameter you pass to the template directive will generate a
+ template variable. There are also some pre-defined variables like PAGE
+ and BASENAME.
+* To insert the value of a variable, use `<TMPL_VAR variable>`. Wiki markup
+ in the value will first be converted to html.
+* To insert the raw value of a variable, with wiki markup not yet converted
+ to html, use `<TMPL_VAR raw_variable>`.
* To make a block of text conditional on a variable being set use
`<TMPL_IF NAME="variable">text</TMPL_IF>`.
* To use one block of text if a variable is set and a second if it's not,
Here's a sample template:
<span class="infobox">
- Name: <TMPL_VAR name><br />
+ Name: [[<TMPL_VAR raw_name>]]<br />
Age: <TMPL_VAR age><br />
<TMPL_IF NAME="color">
Favorite color: <TMPL_VAR color><br />
that contains it, so you can include WikiLinks and all other forms of wiki
markup in the template. Note though that such WikiLinks will not show up as
backlinks to the page that uses the template.
+
+Note the use of "raw_name" inside the [[WikiLink]] generator. This ensures
+that if the name contains something that might be mistaken for wiki markup,
+it's not converted to html before being processed as a [[WikiLink]].
