TL;DR: Here's a video showing an overview of usage.
Advanced Custom Fields, or ACF for short, enables users to add Field Groups, either using a Graphical User Interface, PHP code, or local JSON to various screens in the WordPress dashboard, such as (but not limited to) the Edit Post, Edit User and Edit Term screens.
Whatever method you use to register ACF fields to your WordPress site should work with WPGraphQL for Advanced Custom Fields. For the sake of simplicity, the documentation below will primarily use the Graphic User Interface for examples.
The first step in using Advanced Custom Fields with WPGraphQL is to create an ACF Field Group.
By default, field groups are not exposed to WPGraphQL. You must opt-in to expose your ACF Field Groups and fields to the WPGraphQL Schema as some information managed by your ACF fields may not be intended for exposure in a queryable API like WPGraphQL.
To have your ACF Field Group show in the WPGraphQL Schema, you need to configure the Field Group to "Show in GraphQL".
When using the ACF Graphic User Interface for creating fields, WPGraphQL for Advanced Custom Fields adds a Show in GraphQL field to Field Groups.
Setting the value of this field to "Yes" will show the field group in the WPGraphQL Schema, if a GraphQL Field Name is also set
When registering ACF Fields in PHP, you need to add
graphql_field_name when defining your field group. See below as an example.
Each individual field will inherit its GraphQL name from the supplied
name tag. In this example,
sub_title will become
subTitle when requested through GraphQL. If you want more granular control, you can pass
graphql_field_name to each individual field as well.
In order to document interacting with the fields in GraphQL, an example field group has been created with one field of each type.
For the sake of documentation, this example field group has the location rule set to "Post Type is equal to Post", which will allow for the fields to be entered when creating and editing Posts in the WordPress dashboard, and will expose the fields to the
Post type in the WPGraphQL Schema.
To add an option page and expose it to the graphql schema, simply add 'show_in_graphql' => true when you register an option page.
Alternatively, it's you can check the Fields API Reference to learn about exposing your custom fields to the Schema.
Advanced Custom Fields field groups are added to the WordPress dashboard by being assigned "Location Rules".
WPGraphQL for Advanced Custom Fields uses the Location Rules to determine where in the GraphQL Schema the field groups/fields should be added to the Schema.
For example, if a Field Group were assigned to "Post Type is equal to Post", then the field group would show in the WPGraphQL Schema on the
Post type, allowing you to query for ACF fields of the Post, anywhere you can interact with the
Post type in the Schema.
@todo: Document supported location rules and how they map from ACF to the WPGraphQL Schema
You might notice that some location rules don't add fields to the Schema. This is because some location rules are based on context that doesn't exist when the GraphQL Schema is generated.
For example, if you have a location rule to show a field group only on a specific page, how would that be exposed the the Schema? There's no Type in the Schema for just one specific page.
If you're not seeing a field group in the Schema, look at the location rules, and think about how the field group would be added to a Schema that isn't aware of context like which admin page you're on, what category a Post is assigned to, etc.
If you have ideas on how these specific contextual rules should be handled in WPGraphQL, submit an issue so we can consider how to best support it!
