blocksJSON and previewBlocksJSON missing ACF data

[gustavarrhenius]

First of all, fantastic work on your plugins exposing Gutenberg information from Wordpress!

We feel like its easier to use the JSON fields exposed by blocks and preview to render our frontend to avoid long GraphQL queries and simplify the preview request , but we are missing the full ACF data in the response.

Do you have time to add the ACF data on the JSON fields aswell or guide me in the right direction to add that in the data layer.

Thanks for the positive feedback.

Json will be getting some updates in the next version and will try to mirror the schema even more, I think the acf data will get there also.

Also I am working on being able to query all blocks at once as a flat structure with references to parent blocks and so (no more recursion problems), which should also help with your cause.

A great! I created a temporary solution to modify the output for the JSON data on request.

use WPGraphQLGutenberg\Blocks\PostMeta;
use WPGraphQLGutenberg\PostTypes\BlockEditorPreview;

/**
 * Add ACF Data to Graphql JSON
 */
add_filter('graphql_resolve_field', function($result, $source, $args, $context, $info, $type_name, $field_key, $field, $field_resolver)) {

    if (in_array($field_key, ['blocksJSON', 'previewBlocksJSON'])) {
        $root_id = $source->ID;
        $id = $field_key === 'previewBlocksJSON' ? BlockEditorPreview::get_preview_id($root_id, $root_id) : $root_id;
        $blocks = PostMeta::get_post( $id )['blocks'];
        if (!empty($blocks)) {
            foreach ($blocks as &$block) {
                if (substr($block['name'], 0, 3)  === 'acf') {
                    acf_setup_meta($block['attributes']['data'], $block['attributes']['id'], true);
                    $fields = get_fields();
                    $block['acf'] = $fields;
                }
            }
            $result = json_encode($blocks);
        }
    }
    return $result;

}, 100, 9);
