Drupal 8'de Entity ile Otomatik Tamamlanan Sonuçları Nasıl Değiştirebilirim?

Bazen, otomatik tamamlama sonuçlarında ek veriler görüntülemek, örneğin başlığın yanında içerik dili eklemek veya varlık türünü veya diğer ilgili verileri görüntülemek isteyebilirsiniz. Bu blog yazısında, Drupal 8'deki otomatik tamamlama alanlarındaki önerileri nasıl değiştireceğim göstereceğim.

İşte kullanacağımız modül yapısı:

alter_entity_autocomplete/
  - alter_entity_autocomplete.info.yml
  - alter_entity_autocomplete.services.yml
  - src/
    - EntityAutocompleteMatcher.php
    - Controller/
      - EntityAutocompleteController.php
    - Routing/
      - AutocompleteRouteSubscriber.php

alter_entity_autocomplete.info.yml dosyasının içeriği:

name: Alter Entity Autocomplete
description: The module alters entity autocomplete suggestion list.
type: module
core: 8.x

alter_entity_autocomplete.services.yml dosyasının içeriği:

services:

  alter_entity_autocomplete.route_subscriber:
    class: Drupal\alter_entity_autocomplete\Routing\AutocompleteRouteSubscriber
    tags:
      - { name: event_subscriber }

  alter_entity_autocomplete.autocomplete_matcher:
    class: Drupal\alter_entity_autocomplete\EntityAutocompleteMatcher
    arguments: ['@plugin.manager.entity_reference_selection']

src/EntityAutocompleteMatcher.php dosyasının içeriği. Sonuçların çıktısını değiştireceğiniz dosya budur: sugesstions/autocomplete
