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'));
}
