baru saja membuat ini, yang merupakan solusi lengkap untuk tautan javascript herky-jerk ke bidang formulir. Karena nilai kotak centang Anda diteruskan bersama dengan $ _POST saat kirim, Anda bisa mengambilnya selama filter add_image_attachment_fields_to_save dan mengatur ketentuan objek posting.

return $post;

(perhatikan bahwa saya menggunakan taksonomi ubahsuaian, dan bukan kategori, jadi Anda harus mengubah array $ kategori agar sesuai dengan array yang sama seperti yang Anda gunakan saat mengatur kotak centang)
Shabam, shabozzle. Nikmati.
