다국어 WordPress 사이트를 위한 페이지 번역 (Classic editor)

이 GraphQL 쿼리는 각 사이트가 특정 언어의 번역본이 되는 다국어 사이트 구축을 지원합니다. 콘텐츠는 Classic editor를 기반으로 하며, WordPress 멀티사이트 네트워크와 함께 사용하기에 가장 적합합니다.

이 쿼리를 실행하려면 엔드포인트에서 중첩 뮤테이션이 활성화되어 있어야 합니다.

이 쿼리는 마스터 사이트(소스 콘텐츠가 있는 사이트)에서 실행해야 하며, 해당 사이트에는 “Power Extensions” 번들이 설치되어 있어야 합니다. 네트워크의 다른 모든 사이트는 무료 Gato GraphQL 플러그인을 사용할 수 있습니다.

네트워크 사이트에 연결할 때는 Application Password를 사용합니다. 모든 사이트에 접근 권한이 있는 사용자의 $username 및 $appPassword 변수를 반드시 제공해야 합니다.

쿼리는 메인 사이트와 외부 사이트의 언어를 가져와 비교합니다:

동일한 경우, 모든 페이지를 그대로 복제합니다
다른 경우, 번역된 콘텐츠로 모든 페이지를 복제합니다

(이렇게 하면 메인 사이트의 언어가 en이고 네트워크의 다른 사이트도 en인 경우에도 모든 페이지가 계속 복제됩니다.)

그런 다음 마스터 사이트에서 페이지를 가져와, (필요한 경우) Google Translate API를 단 한 번 호출하여 모든 페이지를 목적지 사이트의 언어로 일괄 번역합니다.

마지막으로 해당 페이지를 모두 외부 사이트에 생성합니다.

# Variables:
#   - $username: The username to log into the external site
#   - $appPassword: The application password to log into the external site
#   - $externalSiteURL: The URL of the external site, where all pages will be (translated and) created
#   - (Optional) $pageIDs: Restrict translating/creating the pages with given IDs
#   - (Optional) $pageStatus: Fetch pages with given status
#   - (Optional) $externalSiteGraphQLEndpointPath: Path to the GraphQL endpoint on the external site

#
# === Description ===
#
# This Persisted GraphQL query helps create a Multilingual site
# where every site is the translation for some language. The content
# is based on the Classic editor, and it is most suitable with a
# WordPress multisite network.
# 
# It must be executed on the master site, which must have the PRO plugin.
# All other sites in the network can have the free Gato GraphQL plugin.
#
# The query retrieves the language from the main site and from the external
# site, and compares them:
#
#   - If they are the same, simply replicate all pages
#   - If they are different, replicate all pages with translated content
#
#   (This way, if the main site has "en" language, and another site in
#   the network also has "en", all pages are still replicated.)
#
# Then it grabs all the pages from the master site, and (if required) it
# translates them all at once (in bulk) to the destination site's language,
# by executing a single call to the Google Translate API.
#
# Finally it creates all those pages in the external site.
