Uwaga: jeśli chcesz dodać to pole do innej taksonomii, np. Dla niestandardowego typu postu, musisz zastąpić odniesienie do kategorii odniesieniem do własnego ślimaka taksonomii. Na przykład, jeśli dodasz stworzoną taksonomię gatunku, możesz przechwycić tę funkcję przez
add_action( 'taxonomy_add_form_fields', array ( $this, 'add_category_image' ), 10, 2 ).
Moja nazwa ślimaka taksonomii to ubezpieczenie.
add Activity ('Insurance_add_form_fields', tablica ($ this, 'add_category_image'), 10, 2);
