当我尝试在 php-codeigniter 中更新查询时，我收到了这个 form_validation 错误。这是我的控制器，这给了我错误，我无法更新或在我的数据库中添加条目

This is my model:
PersonMOdel: Database name is employeeregistration and tableused is tbl_person
<?php
class PersonModel extends CI_Model {
// table name
private $tbl_person= 'tbl_person';
function Person(){
parent::construct();
}
// get number of persons in database
function count_all(){
return $this->db->count_all($this->tbl_person);
}
// get persons with paging
function get_paged_list($limit = 15, $offset = 0){
$this->db->order_by('id','asc');
return $this->db->get($this->tbl_person, $limit, $offset);
}
// get person by id
function get_by_id($id){
$this->db->where('id', $id);
return $this->db->get($this->tbl_person);
}
// add new person
function save($person){
$this->db->insert($this->tbl_person, $person);
return $this->db->insert_id();
}
// update person by id
function update($id, $person){
$this->db->where('id', $id);
$this->db->update($this->tbl_person, $person);
}
// delete person by id
function delete($id){
$this->db->where('id', $id);
$this->db->delete($this->tbl_person);
}
}
?>
这可以看作是一个 CRUD 应用程序。
