fetch database records in codeigniter - php

Question

I'm learning CodeIgniter From this link. I've a little confusion in fetching the data from database.
<h2><?php echo $title; ?></h2>
<?php foreach ($news as $news_item): ?>
<h3><?php echo $news_item['title']; ?></h3>
<div class="main">
<?php echo $news_item['text']; ?>
</div>
<p>View article</p>
While displaying the data in view they have used a variable $news in foreach loop. However this variable is never defined anywhere

Answer 1

Copied from here
$query = $this->db->get('mytable');
// Produces: SELECT * FROM mytable
The second and third parameters enable you to set a limit and offset clause:
$query = $this->db->get('mytable', 10, 20);
// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)
You'll notice that the above function is assigned to a variable named $query, which can be used to show the results:
$query = $this->db->get('mytable');
foreach ($query->result_array() as $row)
{
echo $row['title'];
}

Try like this hope this will give you what you want simply make a controller and call the associated model in the constructor and perform the function what your want it will return the array so you will be eassilly fetch and use it in your view.
Controller code
class TestController extends Controller{
function __construct() {
parent::__construct();
$this->load->helper('url');
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->load->model('User');
}
public function index(){
$data['all_user']=$this->User->getAllUser();
$this->load->view('index',$data);
}
}
this is my model code
class User extends CI_Model{
public function __construct()
{
parent::__construct();
$this->load->database();
}
public function getAllUser()
{
$this->db->select('*');
$this->db->from('users');
return $this->db->get()->result();
}
}
just follow the steps
make a controller
make a function inside the controller
call the associated model function into it and you will definately get the result.

Have you seen this Controller code ? (above the code that you pick, in the tutorial)
public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
$news is passed through as $data element from the Controller to the View
