Renderlet Editable

General

The renderlet is a special container which is able to handle every element in Pimcore (Documents, Assets, Objects). You can decide in your controller/action what to do with the element which is linked to the renderlet. So it's possible to make a multifunctional area in editmode where the editor can drop anything on it. A typical use-case would be to render product objects within a document.

Configuration

Name	Type	Description	Mandatory
controller	string	Specify controller reference, e.g. App\Controller\FooController::myAction	X
template	string	Specify template
className	string or string[]	Specify class name (if type object chosen) as single string or as string array
height	integer or string	Height of the renderlet in pixel or 'auto'
reload	bool	Reload document on change
title	string	Add a title to the box in editmode
type	string	The type of the element assigned to the renderlet (document,asset,object)
width	integer	Width of the renderlet in pixel
class	string	A CSS class that is added to the surrounding container of this element in editmode

Optionally you can pass every parameter (with a scalar data type) you like to the renderlet which can be accessed in the configured controller with $request->get('yourKey').

Methods

Name	Return	Description
isEmpty()	bool	Whether the editable is empty or not.

In the configured Controller Action

In the target controller action, you get the following parameters which can be accessed by $request->get('key').

Name	Type	Description
id	integer	The id of the element assigned to the renderlet
type	string	The type of the element assigned to the renderlet (document,asset,object)
subtype	string	The subtype of the element assigned to the renderlet (folder, image, link, page, classname, ...)

If you have defined any custom parameters on the renderlet configuration you can access them also with $request->get('yourParam').

Example

The code below shows how to use renderlet to create gallery based on it.

Specify the Renderlet Editable in a Template

<section id="renderlet-gallery">
    {{
        pimcore_renderlet('myGallery', {
            "controller" : "App\\Controller\\ContentController::myGalleryAction",
            "title" : "Drag an asset folder here to get a gallery",
            "height" : 400
        })
    }}
</section>

Now editors are able to put elements onto the renderlet in the editmode.

Specify the Controller Action

#[Template('my-gallery.html.twig')]
public function myGalleryAction(Request $request): array
{
    if ('asset' === $request->get('type')) {
        $asset = Asset::getById((int) $request->get('id'));
        if ('folder' === $asset->getType()) {
            return [
                'assets' => $asset->getChildren()
            ];
        }
    }

    return [];
}

The action is responsible for validation and transferring assets to the view. Of course, to limit access to the renderlet, you can use the type configuration option as well.

Create View

Now you have to create the template file at: templates/content/my_gallery.html.twig

{% if assets %}
	<div class="my-gallery">
		{% for asset in assets %}
			{% if asset is instanceof('\\Pimcore\\Model\\Asset\\Image') %}
				<div class="gallery-row">
                    {{ asset.getThumbnail('myThumbnailName').getHTML()|raw }}
				</div>
			{% endif %}
		{% endfor %}
	</div>
{% endif %}

And the final view is like, below:

Editmode

Please be aware, that the renderlet itself is not editmode-aware. If you need to determine within the renderlet whether in editmode or not, you need to pass that parameter to the renderlet.

{{
	pimcore_renderlet('myRenderlet', {
		....
		"editmode" : editmode
	})
}}

Within the renderlet, you can access the editmode parameter as follows:

{% if editmode %}
