Muszę pobrać niestandardowe pola do mojego frontendu (Laravel) z WordPress Backend. Post został pomyślnie zapisany i udało mi się uzyskać identyfikator posta i tytuł, ale nie mogę pobrać wartości z niestandardowego pola. Następnie po tym, jak var_dump zrzucę dane postu. To pokazuje:

AKTUALIZACJA: Drugie dane nawiasów pochodziły z odpowiedzi th AJAX w moim js. Więc get_posts() zwraca tylko pierwszy nawias {}, który nie zawiera wartości pól acf.

Moje pytanie brzmi: jak uzyskać dane z drugiego nawiasu?

Nawiasem mówiąc, używam interfejsu API ACF do REST, dzięki czemu mogę uzyskać dane acf do mojego frontonu Laravel.
