eZ Platform bundle which allows implementing custom logic for custom tags/styles.


  1. Run composer require:
     composer require contextualcode/ezplatform-richtext-template-extension


Lets say you have place_info custom tag. Which has place_location_id paramater. And place_info.html.twig template is used to render it.

Configuration for this custom tag would similar to:

            template: '@ezdesign/field_type/ezrichtext/custom_tag/place_info.html.twig'
            icon: '/bundles/app/img/icons.svg#place_info'
            is_inline: false
                    type: 'number'
                    required: true

Right now params.place_location_id variable is available in place_info.html.twig template. And let's say we need to have place Location object in that template. In order to do so, we need to follow simples steps.

1. Create custom tag extension service class

It need to extend ContextualCode\EzPlatformRichTextTemplateExtension\eZ\RichText\Converter\Render\Template\Extension\Base and extend method need to be implemented. It will return addtional paramters, which will be available in custom tag template. We will inject ezpublish.api.service.location service, and it will be used to load place Location. Also custom tage name need to be passed in parent constructor:


namespace AcmeBundle\CustomTagExtension;

use Exception;
use eZ\Publish\API\Repository\LocationService;
use ContextualCode\EzPlatformRichTextTemplateExtension\eZ\RichText\Converter\Render\Template\Extension\Base;

class Location extends Base
     * @var \eZ\Publish\API\Repository\LocationService
    protected $locationService;

     * @param \eZ\Publish\API\Repository\LocationService
     * @param string $identifier Identifier
     * @param string $type Type: tag or style
    public function __construct(LocationService $locationService, string $identifier, string $type)
        $this->locationService = $locationService;

        parent::__construct($identifier, $type);

     * Returns additional parameters which will be available in the view.
     * You can use injected services here to get them.
     * @param array $params Current set of parameters
     * @return array
    public function extend(?array $params): array
        if (isset($params['place_location_id']) === false) {
            return [];

        try {
            $location = $this->locationService->loadLocation($params['place_location_id']);
        } catch (Exception $e) {
            return [];

        return ['place_location' => $location];

2. Define custom tag extension service

Service need to have ezpublish.ezrichtext.converter.output.template.extension tag. So its definition will be similar to:

        class: AcmeBundle\CustomTagExtension\Location
        tags: [ezpublish.ezrichtext.converter.output.template.extension]
            - '@ezpublish.api.service.location'
            - 'location'
            - 'tag'

3. Use new parameter in template

That is all, now you have params.place_location variable in place_info.html.twig template.
