Create Your Own Bricks

Architecture of a Brick

A brick is an instance of Pimcore\Extension\Document\Areabrick\AreabrickInterface which can either be auto-loaded by saving the brick to a special namespace inside your bundle or by defining the brick as a service and adding it to the list of available bricks through a DI tag. The brick class is the only mandatory file for a brick, however most bricks will at least implement a view template which is rendered in frontend and editmode.

The templates itself are normal templates which are passed to the rendering engine. Therefore you can use all existing templating extensions and Pimcore editables.

Brick registration

A brick will be registered on the system and is represented by a brick ID which has to be unique throughout the system. If a brick ID is registered twice (e.g. by multiple bundles), an error will be raised. The simple way to register a brick is to just save it to a special namespace Document\Areabrick inside your bundle. Every bundle will be scanned for classes implementing AreabrickInterface and all found bricks will be automatically registered to the system. The brick ID will be built from the class name of the implementing class by converting the class name to dashed case. For example a brick named MyCustomAreaBrick will be automatically registered as my-custom-area-brick.

A basic brick implementation could look like the following. As it is defined in the special namespace, Pimcore will implicitely auto-create a service app.area.brick.iframe and register it on the areabrick manager with the ID iframe.

<?php

namespace App\Document\Areabrick;

use Pimcore\Extension\Document\Areabrick\AreabrickInterface;

class Iframe implements AreabrickInterface
{
    // implementing class methods
}

Please note that you need to clear the cache after you added a brick to the special namespace.

If you need more control over the brick instance (e.g. because your brick has dependencies on other services or you want to specify the brick ID manually), you can add the service definition yourself and tag the service with the DI tag pimcore.area.brick. Bricks defined manually will be excluded from the auto-registration, even if they're defined in the special namespace. Let's define our brick as above, but assume it needs access to a logger instance:

# a service.yaml file defining services
services:
    App\Document\Areabrick\Iframe:
        arguments: ['@logger']
        tags:
            - { name: pimcore.area.brick, id: iframe }

This will register the brick as above, but you have control over the brick ID and are able to make use of the container for dependencies.

Although it might be tempting to overwrite the getId() method in your bricks, please make sure the brick always refers to the ID which is set via setId($id) when the brick is registered. Overriding getId() won't affect the brick ID as it is registered on the system as bricks are lazy-loaded. The areabrick manager will set the registered ID when the brick instance is fetched.

Brick template auto discovery

For convenience, you can create a new brick by extending Pimcore\Extension\Document\Areabrick\AbstractTemplateAreabrick to make use of template auto-discovery (thus, needing a minimum of code to get started). The template area brick implements the TemplateAreabrickInterface which defines the following methods you can use to control template auto-discovery. Please make sure your brick is defined inside a bundle as otherwise your templates can't be auto-discovered.

The template location defines the base path which will be used to find your templates. It resolves to the following locations. <bundlePath> is the filesystem path of the bundle the brick resides in, <brickId> the ID of the brick as registered on the areabrick manager (see below).

Location Path
global templates/Areas/<brickId>
bundle <bundlePath>/Resources/views/Areas/<brickId>

Depending on the template location, the following files will be used. You can always completely control locations by implementing the methods for templates and icon yourself (see AreabrickInterface):

Type Location
view template <templateLocation>/view.html.twig

If the brick defines an icon in the public resources directory of the bundle, the icon will be automatically used in editmode. If the icon is at another location, you can override the getIcon() method and specify an URL to be included as icon. When rendering editmode, the following location will be searched for the brick icon and is expected to be a 16x16 pixel PNG: <bundlePath>/Resources/public/areas/<brickId>/icon.png which resolves to the URL
/bundles/<bundleUrl>/areas/<brickId>/icon.png when included in editmode.

Given our iframe brick defined before, the following paths will be used.

global template location

Location Path
view template templates/Areas/iframe/view.html.twig
icon path public/bundles/app/areas/iframe/icon.png
icon URL /bundles/app/areas/iframe/icon.png

bundle template location

The icon path and URL are the same as above, but the view scripts are expected inside the bundle.

Location Path
view template templates/Areas/iframe/view.html.twig

How to Create a Brick

Let's suppose, that our iframe brick defined above is responsible for generating an <iframe> containing contents from a specified URL in the editmode. First of all, let's update the class to add metadata for the extension manager, to make use of template auto-discovery and to load the view template from templates instead of the bundle directory:

<?php
// src/Document/Areabrick/Iframe.php

namespace App\Document\Areabrick;

use Pimcore\Extension\Document\Areabrick\AbstractTemplateAreabrick;

class Iframe extends AbstractTemplateAreabrick
{
    public function getName()
    {
        return 'IFrame';
    }

    public function getDescription()
    {
        return 'Embed contents from other URL (websites) via iframe';
    }

    public function getTemplateLocation()
    {
        return static::TEMPLATE_LOCATION_GLOBAL;
    }
    
    public function needsReload(): bool
    {
        // optional
        // here you can decide whether adding this bricks should trigger a reload
        // in the editing interface, this could be necessary in some cases. default=false
        return false;
    }
}

Let's create a view as next step. Views behave exactly as native controller views and you have access to the current document, to editmode and to editables and templating helpers as everywhere else. In addition there's a instance variable on the view which gives you access to the brick instance. A info variable (see below) gives you access to brick metadata.

/* templates/areas/iframe/view.html.twig */

{% set urlField = pimcore_input('iframe_url') %}
{% set widthField = pimcore_numeric('iframe_width') %}
{% set heightField = pimcore_numeric('iframe_height') %}
{% set transparentField = pimcore_checkbox('iframe_transparent') %}

{% if editmode %}
    <div>
        <h2>IFrame</h2>
        <div>
            URL: {{ urlField }}
        </div>
        <br/>
        <b>Advanced Configuration</b>
        <div>
            Width: {{ widthField }}px (default: 100%)
        </div>
        <div>
            Height: {{ heightField }}px (default: 400px)
        </div>
        <div>
            Transparent: {{ transparentField }} (default: false)
        </div>
    </div>
{% else %}
    {% if not urlField.isEmpty() %}
        
        {% set transparent = 'false' %}
        {% set width = '100%' %}
        {% set height = '400' %}

        {% if not widthField.isEmpty() %}
            {% set width = widthField.data %}    
        {% endif %}

        {% if not heightField.isEmpty() %}
            {% set height = heightField.data %}    
        {% endif %}

        {% if transparentField.isChecked() %}
            {% set transparent = 'true' %}    
        {% endif %}

        <iframe src="{{ urlField }}" width="{{ width }}" height="{{ height }}" allowtransparency="{{ transparent }}" frameborder="0"></iframe>

    {% endif %}
{% endif %}

Now you should be able to see your brick in the list of available bricks on your areablock: Areablock bricks list with the iframe brick

In editmode you can see the configuration for the Iframe brick: Iframe brick - configuration in the editmode

The Brick info-object

Brick views and methods will have access to an Info object containing metadata about the current brick. It is exposed as info variable on views and passed to brick methods as argument. Many methods exist for historical reasons, but a couple of methods could be useful when implementing your own bricks.

Method Description
$info->getEditable() Returns the editable rendering the brick
$info->getDocument() Retrieve the document
$info->getDocumentElement($name) Retrieve the editable tag from document
$info->getRequest() Returns the current request
$info->getIndex() Returns the current index inside the areablock
$info->getParam($name) Retrieve a param passed by globalParams or params config option
$info->getParams() Retrieve all params passed by globalParams or params config option

Editable Dialog (since 6.8)

Sometimes it is necessary to gather some more optional data or provide some configuration options for a brick, which shouldn't be visible by default. For those scenarios the editable dialog is the right tool.

The editable dialog is basically a configurable editing interface where you can use all supported editables in a structured layout in the context of the current brick. The editing interface is configured by implementing the EditableDialogBoxInterface on your brick class and by providing a simple config array.

Simple Example Config

<?php

namespace App\Document\Areabrick;

use Pimcore\Extension\Document\Areabrick\EditableDialogBoxConfiguration;
use Pimcore\Extension\Document\Areabrick\EditableDialogBoxInterface;
use Pimcore\Model\Document;
use Pimcore\Model\Document\Editable\Area\Info;

class WysiwygWithImages extends AbstractAreabrick implements EditableDialogBoxInterface
{
    /**
     * {@inheritdoc}
     */
    public function getName()
    {
        return 'WYSIWYG w. Images';
    }

    public function getEditableDialogBoxConfiguration(Document\Editable $area, ?Info $info): EditableDialogBoxConfiguration
    {
        $config = new EditableDialogBoxConfiguration();
        $config->setWidth(600);
        //$config->setReloadOnClose(true);
        $config->setItems([
            [
                'type' => 'input',
                'label' => 'Some additional Text', // labels are optional
                'name' => 'myDialogInput'
            ],
            [
                'type' => 'checkbox',
                'name' => 'myDialogCheckbox',
                'label' => 'This is the checkbox label',
            ],
            [
                'type' => 'date',
                'name' => 'myDialogDate'
            ]
        ]);


        return $config;
    }
}

Advaned Example Config using Layouts

It is also possible to use tab panels in your configuration.

<?php

namespace App\Document\Areabrick;

use Pimcore\Extension\Document\Areabrick\EditableDialogBoxConfiguration;
use Pimcore\Extension\Document\Areabrick\EditableDialogBoxInterface;
use Pimcore\Model\Document;
use Pimcore\Model\Document\Editable\Area\Info;

class WysiwygWithImages extends AbstractAreabrick implements EditableDialogBoxInterface
{
    /**
     * {@inheritdoc}
     */
    public function getName()
    {
        return 'WYSIWYG w. Images';
    }

    public function getEditableDialogBoxConfiguration(Document\Editable $area, ?Info $info): EditableDialogBoxConfiguration
    {
        $config = new EditableDialogBoxConfiguration();
        $config->setWidth(600);
        $config->setItems([
            'type' => 'tabpanel',
            'items' => [
                [

                    'items' => [
                        [
                            'type' => 'wysiwyg',
                            'label' => 'Some additional Text',

Accessing Data of the Editable Dialog

The editables in the dialog are just normal editables, there's not difference to editables which are defined via the template. So can either use them as well in the template or access them in your custom code.

Methods on the brick class

Sometimes a brick is more than just a view-script and contains some functionality which shouldn't be directly in the view. In this case you can use the action() and postRenderAction() method on the brick class which both get the info object as parameter. The action() method is no real controller action, it is just a little helper to get some logic and code out of the view. However, you can use the action method to prepare data for the view (for example parse request params).

You can return a Response object from action() and postRenderAction() and this response will be sent back to the client.

If you need to influence the HTML open and close tag, you can do so by customizing getHtmlTagOpen() and getHtmlTagClose() (see example below).

<?php

namespace App\Document\Areabrick;

use Pimcore\Extension\Document\Areabrick\AbstractTemplateAreabrick;
use Pimcore\Model\Document\Editable\Area\Info;
use Symfony\Component\HttpFoundation\RedirectResponse;

class Iframe extends AbstractTemplateAreabrick
{
    // other methods defined above
    // 
    public function action(Info $info)
    {
        $myVar = $info->getRequest()->get('myParam');

        $info->setParam('myVar', $myVar);

        // optionally return a response object
        if ('POST' === $info->getRequest()->getMethod()) {
            return new RedirectResponse('/foo');
        }

        return null;
    }

    // OPTIONAL METHODS

    // executed after a brick is rendered
    public function postRenderAction(Info $info)
    {
    }

    // returns a custom html wrapper element (return an empty string if you don't want a wrapper element)
    public function getHtmlTagOpen(Info $info)
    {
        return '<span class="customWrapperDiv">';
    }

    public function getHtmlTagClose(Info $info)
    {
        return '</span>';
    }
}

Examples

You can find many examples in the demo package.
