dropdown list not getting populated in CI - php

Question

I am designing application using CI. and want to show the drop down however its not displaying it.
View
<label>Select Customer</label>
<select name="name" id="name" class="form-control" required="true">
<option selected="">Select Customer</option>
<?php if(isset($client_name)) {
//var_dump($name);
foreach($client_name as $tn)
{
$tn=(array)$tn;
echo '<option selected="" value="'.$tn['name'].'" >'.$tn['name'].'</option>';
//echo '<option selected="" value="'.$tn['tid'].'" >'.$tn['tname'].'</option>';
}
}
else{
echo '<option selected="" value="Data Not found" >Error</option>';
}
?>
</select>
Model:
public function fetch_client(){
$this->db->select('name');
$this->db->distinct();
$this->db->from($this->table);
$query = $this->db->get();
return $query->result();
}
Controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Invoice extends CI_Controller {
public function __construct()
{
parent::__construct();
//$this->load->model('person_model','person');
$this->load->model('client_model','client');
}
public function index()
{
$this->load->helper('url');
//$this->load->view('person_view');
$data['client_name']=$this->client->fetch_client();
$this->load->view('createinvoice',$data);
}
}
The front end is only displaying Error saying data not found. Not sure where I am going wrong. Please help !!!

Answer 1

Edit this
if(isset($client_name))
to
if(isset($client_name) && !empty($client_name))
then remove
selected=""
edit this
$this->db->distinct();
to
$this->db->distinct('id');
if you want use distinct.
you can change "id" to "name" if your table don't use id

Answer 2

Try This Code :
Controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Invoice extends CI_Controller {
public function __construct()
{
parent::__construct();
//$this->load->model('person_model','person');
$this->load->model('client_model','client');
}
public function index()
{
$this->load->helper('url');
//$this->load->view('person_view');
$fetch_record['client_name'] = $this->Model->select('city');
$this->load->view('createinvoice',$fetch_record);
}
}
Model
public function fetch_client($table){
$this->db->distinct();
$this->db->select('name');
$this->db->from($table);
$r= $this->db->get($table);
$res = $r->result();
return $res;
}
View
<label>Select Customer</label>
<select name="name" id="name" class="form-control" required="true">
<option selected="">Select Customer</option>
<?php
if(!empty($client_name))
{
//var_dump($name);
foreach ($client_name as $c)
{
?>
<option value="<?php echo $c->name ?>"><?php echo $c->name; ?></option>
<?php
}
}
else
{
echo '<option selected="" value="Data Not found" >Error</option>';
}
?>
</select>

Answer 3

1.Check the query
var_dump($this->db->last_query());
2.Check the value in Controller
var_dump($data['client_name']);
3.Check the route is correct or not?
route["my-controller/my-method"] = "Invoice/index";
