When the majority of your templates use the same headers and footers, it
is common to split those out into their own templates and
{include} them.
But what if the header needs to have a different title, depending on
what page you are coming from? You can pass the title to the header
as an attribute when
it is included.
Example 21.3. Passing the title variable to the header template
mainpage.tpl - When the main page is drawn,
the title of “Main Page” is passed to the
header.tpl, and will subsequently be used as the title.
{include file='header.tpl' title='Main Page'}
{* template body goes here *}
{include file='footer.tpl'}
archives.tpl - When the
archives page is drawn, the title will be “Archives”.
Notice in the archive example, we are using a variable from the
archives_page.conf
file instead of a hard coded variable.
{config_load file='archive_page.conf'}
{include file='header.tpl' title=#archivePageTitle#}
{* template body goes here *}
{include file='footer.tpl'}
header.tpl - Notice that “Smarty News” is
printed if the $title variable is not set, using the
default
variable modifier.
<html>
<head>
<title>{$title|default:'Smarty News'}</title>
</head>
<body>
footer.tpl
</body>
</html>
