Twig Extensions

Introduction

Twig Extensions are functions, filters and more that offer special functionality to increase usability of view scripts.

Following an overview of some Twig Extensions:

render
render_esi
controller
asset
csrf_token
path
absolute_url
translator
trans
url
relative_path

In addition to the standard Twig extensions, Pimcore adds some additional powerful extensions.

Pimcore Twig Extensions

All Twig extension functions are described below in detail, the following tables give just a short overview of all available extensions.

Extension	Description
`pimcore_cache()`	Simple in-template caching functionality
`pimcore_device()`	Helps implementing adaptive designs
`pimcoreglossary()`	Deprecated: Extension to control the glossary engine
`pimcore_glossary`	Twig Filter: Apply filter on content to pass it to Glossary engine
`pimcore_placeholder()`	Adding and embedding custom placeholders, e.g. for special header tags, etc.
`pimcore_head_link()`	Embeding / managing referenced stylesheets (alternative to `assets()`)
`pimcore_head_meta()`	> elements in your HTML document
`pimcore_head_script()`	> elements
`pimcore_head_style()`	Managing inline styles (pendant to `headLink()` for inline styles)
`pimcore_head_title()`	Create and store the HTML document's `<title>` for later retrieval and output
`pimcore_inc()`	Use this function to directly include a Pimcore document
`pimcore_inline_script`	Managing inline scripts (pendant to `headScript()` for inline scripts)
`pimcore_build_nav()`, `pimcore_render_nav()`, `pimcore_nav_renderer()`	Embed and build navigations based on the document structure
`pimcore_url()`	An alternative to `url()` and `path()`

`pimcore_image_thumbnail()`	Returns a path to a given thumbnail on image
`pimcore_image_thumbnail_html()`	Returns html for displaying the thumbnail image
`pimcore_supported_locales()`	Use this function to get a list of supported locales

Pimcore also adds some Twig tests for evaluating boolean conditions e.g.

{# using 'instaceof' checks if object is instanceof provided classname #}
{% if (product is instanceof('App\\Model\\Product\\Car')) %}
    ...
{% endif %}

{# using 'pimcore_data_object' checks if object is instanceof \Pimcore\Model\DataObject\Concrete #}
{% if (product is pimcore_data_object) %}
 ...
{% endif %}

The following table gives an overview of all available tests:

Test	Description
`instanceof(classname)`	Checks if an object is an instance of a given class
`pimcore_asset`	Checks if object is instanceof Asset
`pimcore_asset_archive`
`pimcore_asset_audio`
`pimcore_asset_document`
`pimcore_asset_folder`
`pimcore_asset_image`
`pimcore_asset_text`
`pimcore_asset_unknown`
`pimcore_asset_video`
`pimcore_data_object`
`pimcore_data_object_folder`
`pimcore_data_object_class(classname)`
`pimcore_data_object_gallery`
`pimcore_data_object_hotspot_image`
`pimcore_document`	Checks if object is instanceof Document
`pimcore_document_email`
`pimcore_document_folder`
`pimcore_document_hardlink`
`pimcore_document_newsletter`
`pimcore_document_page`
`pimcore_document_link`
`pimcore_document_page_snippet`
`pimcore_document_print`
`pimcore_document_print_container`
`pimcore_document_print_page`
`pimcore_document_snippet`

You can also create your own custom Twig Extension to make certain functionalities available to your views.
Here you can find an example how to create your own Twig Extension.

`pimcore_cache`

This is an implementation of an in-template cache. You can use this to cache some parts directly in the template, independent of the other global definable caching functionality. This can be useful for templates which need a lot of calculation or require a huge amount of objects (like navigations, ...).

pimcore_cache( name, lifetime, force)

Name	Type	Description
`name`	string	Name of cache item
`lifetime`	int	Lifetime in seconds. If you define no lifetime the behavior is like the output cache, so if you make any change in Pimcore, the cache will be flushed. When specifying a lifetime this is independent from changes in the CMS.
`force`	bool	Force caching, even when request is done within Pimcore admin interface

Example

{% set cache = pimcore_cache("test_cache_key", 60) %}
{% if not cache.start() %}
    <h1>This is some cached microtime</h1>
    {{ 'now'|date('U') }}
    {% do cache.end() %}
{% endif %}

`pimcore_device`

This extension makes it easy to implement "Adaptive Design" in Pimcore.

Arguments

Name	Type	Description
`default`	string	optional Default if no device can be detected

Example

{% set device = pimcore_device('desktop') %}
{% if device.isPhone() %}
    This is my phone content
{% elseif device.isTablet() %}
    This text is shown on a tablet
{% elseif device.isDesktop() %}
    This is for default desktop Browser
{% endif %}

For details also see Adaptive Design.

`pimcoreglossary`

The pimcoreglossary block replaces glossary terms. See Glossary for details.

Old way (Deprecated):

{% pimcoreglossary %}
My content
{% endpimcoreglossary %}

New way:

{% apply pimcore_glossary %}
My content
{% endapply %}

`pimcore_inc`

Use pimcore_inc() to include documents (eg. snippets) within views. This is especially useful for footers, headers, navigations, sidebars, teasers, ...

pimcore_inc(document, params, cacheEnabled)

Name	Type	Description
`document`	PageSnippet \| int \| string	Document to include, can be either an ID, a path or even the Document object itself
`params`	array	Is optional and should be an array with key value pairs.
`enabledCache`	bool	Is true by default, set it to false to disable the cache. Hashing is done across source and parameters to ensure a consistent result.

Example

{#include path#}
{{ pimcore_inc("/shared/boxes/buttons") }}
 
{#include ID#}
{{ pimcore_inc(256) }}

{#include object#}
{% set doc = pimcore_doc(477) %}
{{ pimcore_inc(doc, {param: 'value'}) }}
  
{#disable caching#}
{{ pimcore_inc(123, null, false) }}

When passing parameters to something included with pimcore_inc(), these parameters are not automatically passed to Twig. The parameters are passed as attributes to the included document, and should be passed to Twig via the document's controller action.

Example:

index.html.twig

{{ pimcore_inc('/some/other/document', { 'parameterToPass': parameterToPass }) }}

IndexController.php (whatever controller / method is designated for /some/other/document in the document tree)

public function otherDocumentAction(Request $request) {
    return ['parameterToPass' => $request->get('parameterToPass')];
}

more Convenient way

public function otherDocumentAction(Request $request) {
    return $this->render(":Default:someOtherDocument.html.twig", ['parameterToPass' => $request->get('parameterToPass')]);
}

someOtherDocument.html.twig (whatever Twig template is actually for /some/other/document in the document tree)

...
{{ parameterToPass }}
...

`pimcore_inline_script`

See InlineScript Template Extension

Navigation

pimcore_build_nav
pimcore_render_nav
pimcore_nav_renderer

Used to interact with navigations. See Navigation for details. Simplified example:

{% set navigation = pimcore_build_nav({
    active: document,
    root: navRootDocument
}) %}
{{ pimcore_render_nav(navigation) }}

{# you can also fetch the renderer instance and call custom render methods #}
{% set renderer = pimcore_nav_renderer('menu') %}
{{ renderer.render(navigation) }}

`pimcore_url`

An alternative to url() and path() which used Url.

{{ pimcore_url(params, name, reset, encode, relative) }}

All parameters are optional here:

Name	Type	Description
`params`	array	Route params. If object is passed in the params then link generator will be used to generate Url
`name`	string	Route name
`reset`	bool	Is false by default, set it to false to avoid merging parameters from request
`encode`	bool	Is true by default, set it to false to disable encoding
`relative`	bool	Is false by default, set it to true to generate a relative path based on the current request path

Example

{% set object = pimcore_object(769) %}
{{  pimcore_url({'object': object}) }}
