graphql_compose_entity_form_modes

Exposes entity form mode field definitions and structure via GraphQL for headless applications.

Requirements

• Drupal 10.1+
• PHP 8.1+
• GraphQL Compose
• GraphQL Compose Mutations

Schema Extension

Adds the entityFormMode field to the Query root type:

extend type Query {
  entityFormMode(
    entity_type: EntityType!
    entity_bundle: String!
    entity_id: String
    operation: Operation
  ): EntityFormModeResponse
}

Response Type

type EntityFormModeResponse implements Response {
  success: Boolean
  errors: [Violation]
  form: Json
  form_mode_fields: Json
  form_mode_field_groups: Json
}

Query Example

Retrieve form fields for a node bundle (create operation)

query GetNodeFormFields {
  entityFormMode(
    entity_type: NODE
    entity_bundle: article
    operation: CREATE
  ) {
    success
    errors {
      message
    }
    form_mode_fields {
      machine_name
      type
      required
      weight
      settings {
        cardinality
        type
      }
      widget {
        #type
        #title
        #description
        #required
      }
      existing_values
    }
    form_mode_field_groups {
      machine_name
      label
      format_type
      parent_field_group
      children
      weight
    }
  }
}

Retrieve form with pre-filled values (update operation)

query GetNodeFormFields {
  entityFormMode(
    entity_type: NODE
    entity_bundle: article
    entity_id: "123"
    operation: UPDATE
  ) {
    success
    form_mode_fields {
      machine_name
      existing_values
    }
  }
}

Permission Handling

Access control uses graphql_compose_mutations.user_permissions service:

• Validates user permissions via userCanDoActionOnEntityByType()
• Administrators (uid=1 or 'administrator' role) bypass permission checks
• Returns validation violations if access is denied

Widget Properties Filter

To prevent JSON recursion, only these widget properties are returned:

• #base_type, #date_date_format, #date_time_format, #date_timezone, #date_year_range
• #delta, #description, #description_display, #form_group, #id, #name
• #options, #placeholder, #required, #title, #title_display, #type
