A set of extensions for core media blocks in order to support Drupal's media attributes.
Install the package from NPM.
$ npm install @frontkom/g-media-attributes
Add to the editor before the core blocks are loaded:
import '@frontkom/g-media-attributes';
In order to fully support Drupal's file entity when handling images on Gutenberg editor, the tags on core media blocks need to have the
data-entity-uuid and data-entity-type attributes.
The block resulting HTML must be something like this:
<figure class="wp-block-image">
<img data-entity-uuid="f398bc3b-1c50-4394-bf80-3af0f72fef42" data-entity-type="file" src="..."
alt="Picture" class="wp-image-1">
</figure>
The data-* attributes are provided by api-fetch's upload method.
The following core blocks needed to be updated:
- core/image
- core/video
- core/media-text
- core/cover
- core/gallery
The solution we found was to wrap the Edit and Save components with Higher Order Components's (HOC) that handle the fetching and printing of these media attributes.
settings.edit = editWithMediaAttrs(settings.edit);
settings.save = saveWithMediaAttrs(settings.save);
When an image is selected, the Edit HOC captures that event and fecthes the additional data required from the API.
On save, the Save HOC updates the rendered tree with the necessary attributes for each media element.
- core/gallery
Currently the block validation for core/gallery throws an error to the console. However, this does not affect the loading of the block itself. It seems to be caused by the difference in number of attributes present on each of the gallery items (expected vs actual). More discovery is needed.
