Содержание
The templates may come from a variety of sources. When you
display() or
fetch()
a template, or when you include a template from within another template,
you supply a resource type, followed by the appropriate path and template
name. If a resource is not explicitly given, the value of
$default_resource_type
(default: "file") is assumed.
Smarty ships with a built-in template resource for the filesystem. The file: is the default resource.
The resource key file: must only be specified, if the
$default_resource_type has been changed.
If the file resource cannot find the requested template, the
$default_template_handler_func
is invoked.
Замечание
As of Smarty 3.1 the file resource no longer walks through the
include_path unless
$use_include_path is activated
The file resource pulls templates source files from the directories specified in
$template_dir.
The list of directories is traversed in the order they appear in the array.
The first template found is the one to process.
Пример 16.1. Using templates from the $template_dir
<?php
$smarty->display('index.tpl');
$smarty->display('file:index.tpl'); // same as above
?>
From within a Smarty template
{include file='index.tpl'}
{include file='file:index.tpl'} {* same as above *}
Smarty 3.1 introduced the bracket-syntax for specifying an element from
$template_dir.
This allows websites employing multiple sets of templates better control over
which template to acces.
The bracket-syntax can be used from anywhere you can specify the
file: resource type.
Пример 16.2. Specifying the $template_dir to use
<?php
// setup template directories
$smarty->setTemplateDir(array(
'./templates', // element: 0, index: 0
'./templates_2', // element: 1, index: 1
'10' => 'templates_10', // element: 2, index: '10'
'foo' => 'templates_foo', // element: 3, index: 'foo'
));
/*
assume the template structure
./templates/foo.tpl
./templates_2/foo.tpl
./templates_2/bar.tpl
./templates_10/foo.tpl
./templates_10/bar.tpl
./templates_foo/foo.tpl
*/
// regular access
$smarty->display('file:foo.tpl');
// will load ./templates/foo.tpl
// using numeric index
$smarty->display('file:[1]foo.tpl');
// will load ./templates_2/foo.tpl
// using numeric string index
$smarty->display('file:[10]foo.tpl');
// will load ./templates_10/foo.tpl
// using string index
$smarty->display('file:[foo]foo.tpl');
// will load ./templates_foo/foo.tpl
// using "unknown" numeric index (using element number)
$smarty->display('file:[2]foo.tpl');
// will load ./templates_10/foo.tpl
?>
From within a Smarty template
{include file="file:foo.tpl"}
{* will load ./templates/foo.tpl *}
{include file="file:[1]foo.tpl"}
{* will load ./templates_2/foo.tpl *}
{include file="file:[foo]foo.tpl"}
{* will load ./templates_foo/foo.tpl *}
Templates outside of the
$template_dir
require the file: template resource type, followed by
the absolute path to the template (with leading slash.)
Замечание
With Security enabled,
access to templates outside of the
$template_dir
is not allowed unless you list those directories in $secure_dir.
Пример 16.3. Using templates from any directory
<?php
$smarty->display('file:/export/templates/index.tpl');
$smarty->display('file:/path/to/my/templates/menu.tpl');
?>
And from within a Smarty template:
{include file='file:/usr/local/share/templates/navigation.tpl'}
If you are using a Windows machine, filepaths usually include a
drive letter (C:) at the beginning of the pathname. Be sure to use
file: in the path to avoid namespace conflicts and
get the desired results.
Пример 16.4. Using templates from windows file paths
<?php
$smarty->display('file:C:/export/templates/index.tpl');
$smarty->display('file:F:/path/to/my/templates/menu.tpl');
?>
And from within Smarty template:
{include file='file:D:/usr/local/share/templates/navigation.tpl'}
