Overview

This plugin provides an integration for Meta Box and WPGraphQL.

By simply adding an extra graphql_name property to the field registration the field will be exposed in the GraphQL schema.

Usage:

This assume you know how to expose custom post types in WPGraphQL - read their documentation for further info.

Using Meta Box, define a custom field. Copy and paste the generated code to your functions.php (or where ever you store your custom code).

wp-graphql-metabox options

option	type	effect
graphql_name	string	adds the field to the GraphQL object(s) identified in post_types
graphql_mutate	boolean	adds the field to the GraphQL object(s) create and update mutation input

Add in the graphql_name to the field definition:

$meta_boxes[] = [
    'title' => 'Extra Fields',
    'id' => 'extra-fields',
    'post_types' => [
        0 => 'post',
    ],
    'context' => 'after_title',
    'priority' => 'high',
    'autosave' => true,
    'fields' => [
        [
            'id' => 'a_random_number',
            'name' => 'A Random Number',
            'type' => 'number',
            'std' => 5,
            'columns' => 2,
            'size' => 3,
            'graphql_name' => 'randomNumber',
            'graphql_mutate' => true
        ],
    ],
];

That's it. The field randomNumber will be exposed on the type post. This will work for any custom post types you may create.

NB: You must expose custom types by adding show_in_graphql to the configuration of the CPT.

A simple query might look like this:

query {
    posts {
        nodes {
            title
            content
            randomNumber
        }
    }
}
