Başka bir WordPress sitesinden gönderi içe aktar

Bu query, yukarı akıştaki bir WordPress sitesinden yerel WordPress sitemize bir gönderi içe aktarır.

Gato GraphQL eklentisinin (ücretsiz sürüm) yukarı akış web sitesine kurulu olması gerekir.

Gönderide referans verilen kaynakların tamamının yerel ortamda mevcut olması gerekir:

  • Yazar
  • Öne çıkan görsel (varsa)
  • Kategoriler
  • (Etiketler de dahil olmak üzere; ancak bunlar henüz mevcut değilse gönderiyle birlikte oluşturulur, dolayısıyla sorun teşkil etmez)

Yukarı akış ve yerel siteler arasındaki kaynaklar için ortak tanımlayıcı olarak şunları kullanırız:

  • Kategoriler, etiketler ve medya öğeleri için slug değerleri
  • Kullanıcılar için kullanıcı adları

Kaynaklardan herhangi biri yerel sitede mevcut değilse, GraphQL query bir hata yazdırır ve içe aktarma işlemini durdurur.

$upstreamServerGraphQLEndpointURL değişkeni, yukarı akış WordPress sitesindeki Gato GraphQL uç noktasıdır; $postSlug ise içe aktarılacak gönderinin slug değeridir.
