我在使用codeigniter时遇到问题，当我点击提交时，它不会更新数据。
我正在创建超级管理员，以便删除或更新正常的管理员数据。
这是我的代码：
控制器
<?php
class Superadmin extends MY_Controller
{
public function __construct()
{
parent::__construct();
//$this->session->userdata('is_login') == FALSE || redirect('admin/Login_admin');
if($this->session->userdata('token'))
$this->session->unset_userdata('token');
$this->load->model('admin/Admin_m');
}
public function index()
{
if(isset($this->session->id)=='')
{
redirect('admin/Login');
}
$data['content'] = 'page/admin/superadmin';
$data['admin'] = $this->Admin_m->get_all();
$this->load->view('layout_admin', $data);
}
public function editadmin($admin_id)
{
if(isset($this->session->id)=='')
{
redirect('admin/Login');
}
$data['content'] = 'page/admin/superadminedit';
$data['admin'] = $this->Admin_m->get_admin_by_id($admin_id);
if($this->form_validation->run() == FALSE)
{
$this->load->view('page/admin/superadminedit', $data);
}
else
{
$this->form_validation->set_rules('full_name', ' Full name', 'required');
$this->form_validation->set_rules('user', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required|min_length[5]');
// kondisi untuk input data jika password kosong
if($this->input->post('password') == ''){
$data =
array(
'full_name' => $this->input->post('full_name'),
'user' => $this->input->post('user'),
'level' => $this->input->post('level'),
);
}
else
{
$data =
array(
'full_name' => $this->input->post('full_name'),
'user' => $this->input->post('user'),
'password' => hashpassword($this->input->post('password')),
'level' => $this->input->post('level'),
);
}
$this->Admin_m->edit_admin($admin_id,$data);
redirect('admin/superadmin/editadmin');
}
}
public function deleteadmin($id)
{
if(isset($this->session->id)=='')
{
redirect('admin/Login');
}
$this->load->model('Admin_m');
$this->Admin_m->delete($id);
//$this->session->set_flashdata('remove_success', 'Admin berhasil dihapus dari List');
redirect('admin/Superadmin');
}
}
?>
模型
<?php
class Admin_m extends CI_Model
{
public function check_akunadmin($user= '' , $password = '')
{
return $this->db->get_where('admin_user',
array('user' =>$user,
'password' => hashpassword($password)
)
)->row();
}
public function insert($data = array())
{
$this->db->insert('admin_user',$data);
}
public function edit_admin($id, $data = array())
{
$this->db->where('id', $id);
$this->db->set($data);
$this->db->update('admin_user');
}
public function get_admin_by_id($admin_id)
{
return $this->db->get_where('admin_user', array('id' => $admin_id))->row();
}
public function get_all($per_page = 0, $offset = 0)
{
$this->db->order_by('id', 'desc');
return $this->db->limit($per_page, $offset)->get('admin_user')->result();
}
public function delete($id)
{
$this->db->where('id', $id);
$this->db->delete('admin_user');
}
}
?>

点击视图页面上的提交后，它不会在数据库中更新...
出了什么问题？我希望有人理解并向我解释......非常感谢你帮助我。
答案 0 :(得分：1)
试试这个：
public function edit_admin($id, $data = array())
{
$this->db->where('id', $id);
$this->db->update('admin_user', $data);
}
另外，执行print_r（$ data）;退出;就在检查模型是否正确接收数据之前。
OFF：让我帮你一把......没有必要重复整个阵列。
if($this->input->post('password') == ''){
$data =
array(
'full_name' => $this->input->post('full_name'),
'user' => $this->input->post('user'),
'level' => $this->input->post('level'),
);
}
else
{
$data =
array(
'full_name' => $this->input->post('full_name'),
'user' => $this->input->post('user'),
'password' => hashpassword($this->input->post('password')),
'level' => $this->input->post('level'),
);
}
应该是：
$data =
array(
'full_name' => $this->input->post('full_name'),
'user' => $this->input->post('user'),
'level' => $this->input->post('level'),
);
if(!empty($this->input->post('password'))){
$data['password'] = hashpassword($this->input->post('password'));
}
