404 Page not found Codeigniter
Question
I'm new to codeigniter. I'm making crud from a tutorial, whenever I clicked the Edit.
It links to.. http://localhost/crud/index.php/users/edit/1
and I'm getting I'm getting 404 Page not Found.
I think it's just a problem on the uri or pagination of the controllers. What would be the problem?
users.php - controller
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Users extends CI_Controller {
function __construct()
{
parent::__construct();
#$this->load->helper('url');
$this->load->model('users_model');
}
public function index()
{
$data['user_list'] = $this->users_model->get_all_users();
$this->load->view('show_users', $data);
}
public function add_form()
{
$this->load->view('insert');
}
public function insert_new_user()
{
$udata['name'] = $this->input->post('name');
$udata['email'] = $this->input->post('email');
$udata['address'] = $this->input->post('address');
$udata['mobile'] = $this->input->post('mobile');
$res = $this->users_model->insert_users_to_db($udata);
if($res){
header('location:'.base_url()."index.php/users/".$this->index());
}
}
public function delete_a_user($id)
{
$this->db->where('users.id',$id);
return $this->db->delete('users');
}
public function delete($id)
{
$this->users_model->delete_a_user($id);
$this->index();
}
public function update()
{
$mdata['name']=$_POST['name'];
$mdata['email']=$_POST['email'];
$mdata['address']=$_POST['address'];
$mdata['mobile']=$_POST['mobile'];
$res=$this->users_model->update_info($mdata, $_POST['id']);
if($res){
header('location:'.base_url()."index.php/users/".$this->index());
}
}
}

You forgot to add the function edit in your controller. In your case it will be something like this:
function edit($id)
{
$mdata['name']=$_POST['name'];
$mdata['email']=$_POST['email'];
$mdata['address']=$_POST['address'];
$mdata['mobile']=$_POST['mobile'];
$res=$this->users_model->update_info($mdata, $id);
...
}

You have a couple of errors, first you must to rename your "update" method to "edit".
public function edit($id) {
$mdata['name'] = $_POST['name'];
$mdata['email'] = $_POST['email'];
$mdata['address'] = $_POST['address'];
$mdata['mobile'] = $_POST['mobile'];
$res = $this->users_model->update_info($mdata, $id);
if($res)
// this is wrong too.. $this->index() execute the index method
// header('location:'.base_url()."index.php/users/".$this->index());
// use redirect function like this
redirect('users/index');
}

I can not see a function in your controller called "edit". The way CI URLs work by default, is that the first segment "users" is the controller, class name (Users). - The file and class must have the same name. The second segment of the URL "edit" will be the name of a function within the class. In your case your URL is looking for class "Users" and a function called "edit" within that class, and "edit" does not exist!
Add this.
public function edit(){
// do your stuff here
}

In your users.php - controller may be a function edit like something:
function edit() {
$this->user_model->edi_user();
redirect('http://url.com/user/');
}
And in model:
public function edit_user(){
$id = $this->session->userdata('user_id');
$data = array(
'name' => $this->input->post('name'),
'lastname' => $this->input->post('lastname'),
);
$this->db->where('id', $id);
$this->db->update('users', $data);
}
