HTML entities are not being decoded when using WordPress REST API for Gutenberg blocks
It's not immediately obvious, but there is in fact a method made available in the Blocks API to do this.
At the top of your block code, type:
const { decodeEntities } = wp.htmlEntities;Then you can use it like this:
const options = response.data.map((post) => { return { label: decodeEntities(post.title.rendered), value: post.id, };});Bazoozaa! HTML entities are gone.
And why not using rest_prepare_<post_type> filter ?
$post_type = "post"add_filter( "rest_prepare_".$post_type, 'prefix_title_entity_decode'] , 10, 1 ); function prefix_title_entity_decode($response){ $data = $response->get_data(); $data['title']['rendered'] = html_entity_decode( $data['title']['rendered']); $response->set_data($data); return $response;}
