Extended Template Parts

Extended Template Parts is a library which provides extended functionality to WordPress template parts, including template variables and fragment caching.

Features

• Pass variables into your template parts and access them via the $this->vars array. No polluting of globals!
• Easy optional caching of template parts using transients.

Minimum Requirements

PHP: 7.0
WordPress: 4.4

Installation

Extended Template Parts is a developer library, not a plugin, which means you need to include it somewhere in your own project. You can use Composer:

composer require johnbillion/extended-template-parts

Or you can download the library and include it manually:

require_once 'extended-template-parts/extended-template-parts.php';

Basic Usage

The get_extended_template_part() function behaves exactly like WordPress' get_template_part() function, except it loads the template part from the template-parts subdirectory of the theme for better file organisation. The usual parent/child theme hierarchy is respected.

get_extended_template_part( 'foo', 'bar' );

Use the $vars parameter to pass in an associative array of variables to the template part:

get_extended_template_part( 'foo', 'bar', [
	'my_variable' => 'Hello, world!',
] );

In your template-parts/foo-bar.php template part file, you can access the variables that you passed in by using $this->vars:

echo esc_html( $this->vars['my_variable'] );

Advanced Usage

The get_extended_template_part() function also accepts a second optional parameter that controls the directory name and caching.

The following code will load foo-bar.php from the my-directory subdirectory and automatically cache its output in a transient for one hour:

get_extended_template_part( 'foo', 'bar', [
	'my_variable' => 'Hello, world!',
], [
	'dir'   => 'my-directory',
	'cache' => 1 * HOUR_IN_SECONDS,
] );
