If you are updating a sub field of another field then you need to supply an array when updating the field.

Assuming that you are using a group field due to the lack of index values between “parent_field” and “sub_field”. If it’s not a group field and you’re using a repeater let me know and I will give you the correct array structure for repeaters.

$value = array(
  // subfield key => value pairs
  'field_XXXXX' => 'value',
  'field_YYYYY' => 'value'
)
// where field_AAAAA is the parent field
update_field('field_AAAAAA', $value, $post_id);
