File Template Resources {#resources.file}
=======================
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
[`$default_resource_type`](#variable.default.resource.type) has been
changed.
If the file resource cannot find the requested template, the
[`$default_template_handler_func`](#variable.default.template.handler.func)
is invoked.
> **Note**
>
> As of Smarty 3.1 the file resource no longer walks through the
> [include\_path](https://www.php.net/ini.core.php#ini.include-path) unless
> [`$use_include_path` is activated](#variable.use.include.path)
Templates from \$template\_dir {#templates.from.template.dir}
------------------------------
The file resource pulls templates source files from the directories
specified in [`$template_dir`](#variable.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.
<?php
$smarty->display('index.tpl');
$smarty->display('file:index.tpl'); // same as above
?>
From within a Smarty template
{include file='index.tpl'}
{include file='file:index.tpl'} {* same as above *}
Templates from a specific \$template\_dir {#templates.from.specified.template.dir}
-----------------------------------------
Smarty 3.1 introduced the bracket-syntax for specifying an element from
[`$template_dir`](#variable.template.dir). This allows websites
employing multiple sets of templates better control over which template
to access.
The bracket-syntax can be used from anywhere you can specify the `file:`
resource type.
<?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)
$smarty->display('file:[2]foo.tpl');
// will load ./templates_10/foo.tpl
?>
From within a Smarty template
{include file="file:foo.tpl"}
{* will load ./templates/foo.tpl *}
{include file="file:[1]foo.tpl"}
{* will load ./templates_2/foo.tpl *}
{include file="file:[foo]foo.tpl"}
{* will load ./templates_foo/foo.tpl *}
Templates from any directory {#templates.from.any.dir}
----------------------------
Templates outside of the [`$template_dir`](#variable.template.dir)
require the `file:` template resource type, followed by the absolute
path to the template (with leading slash.)
> **Note**
>
> With [`Security`](#advanced.features.security) enabled, access to
> templates outside of the [`$template_dir`](#variable.template.dir) is
> not allowed unless you list those directories in `$secure_dir`.
<?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'}
Windows Filepaths {#templates.windows.filepath}
-----------------
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.
<?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'}
