My program is not working properly, i do not know what should i do :S
Here is my code: My controller file (Home):
<?php
class Home extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model("Crudmodel");
}
public function index(){
# get all data in Study table
$selectStudys = $this->Crudmodel->selectStudys();
foreach ($selectStudys as $key => $study)
{
# get UserNames
$user = $this->Crudmodel->getName($study['user_id']);
#get Subject Names
$subject = $this->Crudmodel->getSubName($study['subject_id']);
#append both NEW VALUES to same array
if(!empty($user[0]['username'])){
$data[$key]['user_id'] = $user[0]['username'];
// your main problem can be this. may be it is not getting value from query this is why we have put validation on model function and error handler condition here
}else{
$data[$key]['user_id'] = ''; // or anything as your else condition you can use as error handler
}
if(!empty($subject[0]['name'])){
$data[$key]['subject_id'] = $subject[0]['name'];
// your main problem can be this. may be it is not getting value from query this is why we have put validation on model function and error handler condition here
}else{
$data[$key]["subject_id"] = "";
// or anything you can use as error handler
}
}
$data['records'] = $selectStudys;
$this->load->view('home', $data);
}
}
?>
Crudmodel:
class Crudmodel extends CI_Model{
public function __construct(){
parent::__construct();
$this->load->database();
}
function selectStudys()
{
$query= $this->db->query("SELECT * FROM cursadas");
if($query->num_rows()>0){
$result = $query->result_array();
}else{
$result = "";
// or anything you can use as error handler
return $result;
}
}
function getName($name)
{
$query= $this->db->query("SELECT username FROM usuarios WHERE id = $name ");
if($query->num_rows()>0){
$result = $query->result_array();
}else{
$result = "";
// or anything you can use as error handler
return $result;
}
}
