Load link- or script-assets to the document from inside your TWIG template.

Contao Twig Assets

Adding assets via the global array $GLOBALS is no more possible when using TWIG templates. This Bundle for the Contao CMS provides 5 TWIG functions to load assets from inside your TWIG template.

Usage

Each of these five functions take two parameters e.g. addJavascriptResource($resource_path, $position) The first parameter '$resource_path' is mandatory, while the second parameter '$position' is optional.

Default usage:

{# Inside your twig template: #}

{% do addJavascriptResource('bundles/contaofoobarplugin/js/my.js|static') %}
{# Same as $GLOBALS['TL_JAVASCRIPT'][] = 'bundles/contaofoobarplugin/js/my.js|static'; #}

Set a javascript resource at a fixed position or replacing it:

{# Inside your twig template: #}

{% do addJavascriptResource('bundles/contaofoobarplugin/js/my.js|static', 2) %}
{# Same as $GLOBALS['TL_JAVASCRIPT'][2] = 'bundles/contaofoobarplugin/js/my.js|static'; #}

Overview

{# Inside your twig template: #}

{% do addJavascriptResource('bundles/contaofoobarplugin/js/my.js|static') %}
{# Same as $GLOBALS['TL_JAVASCRIPT'][] = 'bundles/contaofoobarplugin/js/my.js|static'; #}

File make time

Get the file make time of a script or css asset and append the version parameter to ensure that clients always receive the latest version of the asset, when it changes.

{# Inside your twig template: #}

{% set fileMakeTime = getFileMakeTime('vendor/foo-bar-bundle/public/css/my.css') %}.
{% do addCssResource('bundles/foobar/css/my.css|' ~ fileMakeTime) %}
{# --> bundles/foobar/css/my.css?v=93449db6 #}
