{include}

{include}
Prev	Chapter 7. Built-in Functions	Next

{include} tags are used for including other templates in the current template. Any variables available in the current template are also available within the included template.

The {include} tag must have the file attribute which contains the template resource path.
Setting the optional assign attribute specifies the template variable that the output of {include} is assigned to, instead of being displayed. Similar to {assign}.
Variables can be passed to included templates as attributes. Any variables explicitly passed to an included template are only available within the scope of the included file. Attribute variables override current template variables, in the case when they are named the same.
You can use all variables from the including template inside the included template. But changes to variables or new created variables inside the included template have local scope and are not visible inside the including template after the {include} statement. This default behaviour can be changed for all variables assigned in the included template by using the scope attribute at the {include} statement or for individual variables by using the scope attribute at the {assign} statement. The later is useful to return values from the included template to the including template.
Use the syntax for template resources to {include} files outside of the $template_dir directory.

Example 7.46. Simple {include} example


<html>
<head>
  <title>{$title}</title>
</head>
<body>
{include file='page_header.tpl'}

{* body of template goes here, the $tpl_name variable
   is replaced with a value eg 'contact.tpl'
*}
{include file="$tpl_name.tpl"}

{* using shortform file attribute *}
{include 'page_footer.tpl'}
</body>
</html>

Example 7.47. {include} passing variables


{include 'links.tpl' title='Newest links' links=$link_array}
{* body of template goes here *}
{include 'footer.tpl' foo='bar'}

The template above includes the example links.tpl below


<div id="box">
<h3>{$title}{/h3>
<ul>
{foreach from=$links item=l}
.. do stuff  ...
</foreach}
</ul>
</div>

Example 7.48. {include} using parent scope

Variables assigned in the included template will be seen in the including template.


{include 'sub_template.tpl' scope=parent}
...
{* display variables assigned in sub_template *}
{$foo}<br>
{$bar}<br>
...

The template above includes the example sub_template.tpl below


...
{assign var=foo value='something'}
{assign var=bar value='value'}
...

Example 7.49. {include} with disabled caching

The included template will not be cached.


{include 'sub_template.tpl' nocache}
...

Example 7.50. {include} with individual cache lifetime

In this example included template will be cached with an individual cache lifetime of 500 seconds.


{include 'sub_template.tpl' cache_lifetime=500}
...

Example 7.51. {include} with forced caching

In this example included template will be cached independent of the global cahing setting.


{include 'sub_template.tpl' caching}
...

Example 7.52. {include} and assign to variable

This example assigns the contents of nav.tpl to the $navbar variable, which is then output at both the top and bottom of the page.

 
<body>
  {include 'nav.tpl' assign=navbar}
  {include 'header.tpl' title='Smarty is cool'}
    {$navbar}
    {* body of template goes here *}
    {$navbar}
  {include 'footer.tpl'}
</body>

Example 7.53. {include} with relative paths

This example includes another template relative to the directory of the current template.


   {include 'template-in-a-template_dir-directory.tpl'}
   {include './template-in-same-directory.tpl'}
   {include '../template-in-parent-directory.tpl'}

Example 7.54. Various {include} resource examples


{* absolute filepath *}
{include file='/usr/local/include/templates/header.tpl'}

{* absolute filepath (same thing) *}
{include file='file:/usr/local/include/templates/header.tpl'}

{* windows absolute filepath (MUST use "file:" prefix) *}
{include file='file:C:/www/pub/templates/header.tpl'}

{* include from template resource named "db" *}
{include file='db:header.tpl'}

{* include a $variable template - eg $module = 'contacts' *}
{include file="$module.tpl"}

{* wont work as its single quotes ie no variable substitution *}
{include file='$module.tpl'}

{* include a multi $variable template - eg amber/links.view.tpl *}
{include file="$style_dir/$module.$view.tpl"}
