Answer 1

Try this,

public function delete_all($id_pris){
   $this->db->set('p.active', '0');
   $this->db->where('f.id_prisoners', $id_pris);
   $data_result = $this->db->update('tbl_person p JOIN tbl_family f ON p.id_person = f.id_person');
   return  $data_result;
}

Answer 2

You have minute error in your script, you missed alias of slave table

VERSION 1

public function delete_all($id_pris){
   $this->db->join('tbl_family f','p.id_person = f.id_person',"inner"); // you missed `f` here
   $this->db->set('p.active', '0');
   $this->db->where('f.id_prisoners', $id_pris);
   $data_result = $this->db->update('tbl_person p');
   return  $data_result;
}

This should work fine.

VERSION 2

$this->db->set('p.active', '0');
$this->db->where('f.id_prisoners', $id_pris);
$this->db->where('p.id_person = f.id_person')
$data_result = $this->db->update('tbl_family as f, tbl_person as p');
return $data_result;

VERSION 3

$sql = "
UPDATE tbl_person p
INNER JOIN tbl_family_victim f  ON  p.id_person = f.id_person
SET p.active = 0
WHERE f.id_prisoners = $id_pris";
$this->db->query($sql);

VERSION 4

$this->db->set('p.active', '0');
$this->db->where('f.id_prisoners', $id_pris);
$data_result = $this->db->update('tbl_family as f JOIN  tbl_person as p ON p.id_person = f.id_person');
return $data_result;
