Setelah plugin diperbarui, itu akan mengatur tugas menjadi db menggunakan set_transient()
fungsi. Tidak disarankan untuk menambahkan kode pembaruan saat menelepon upgrader_process_complete
hook.
Selanjutnya, jika Anda menjelajah ke halaman admin lain, plugins_loaded
hook akan berfungsi dan kode pembaruan akan berfungsi di sana.
Harap dicatat bahwa plugin ini harus diaktifkan untuk membuat pengait pembaruan berfungsi.
Ini tidak berfungsi pada plugin aktif jadi, jika Anda ingin kode yang berfungsi mengaktifkan plugin Anda harus kode dalam register_activation_hook()
fungsinya.
