How to get Custom Field data on WPGraphQL

I add a custom field for upload featured image for category. Now I want to get this value on WPGraphQL Query.

Answer 1

You still have to register your custom field to the GraphQL schema using the register_graphql_field() function.

add_action( 'graphql_register_types', function() {
    register_graphql_field( 'PostCategory', 'categoryImage', [
        'type' => 'MediaItem',
        'resolve' => function( $post ) {
            $image = get_post_meta( $post->databaseId, 'category_image_id'  );
            return ! empty( $image ) ? $image : null;
        }
    ]);
});

Reference the WPGraphQL custom field recipes for more info here
