query result using codeIgniter - php

Question

It is the first time for me to use codeIgniter, I tried to build a simple DB driven application.
First the model:
class News_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_news()
{
$query = $this->db->get('news');
return $query->result_array();
}
}
second the controller
class News extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('news_model');
}
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);
$this->load->view('templates/footer');
}
The view "index":
<?php foreach ($news as $news_item): ?>
<h2><?php echo $news_item['title'] ?></h2>
<div id="main">
<?php echo $news_item['text'] ?>
</div>
<p>View article</p>
<?php endforeach ?>
When I run the code it displays the header and the footer, but no database record is displayed.
If I put a print statement in the view outside the foreach it works, but not inside the foreach.
I use if($news) to find out if the query retrieved any result, but there is no result retrieved.
How can I know why there is no result retrieved from the DB?

Answer 1

You need to call another foreach inside your foreach. example:
foreach ($result as $row) {
foreach ($row as $key => $val) {
if ($key === "reservation_info") {
$data['decoded'] = json_decode($val);
} else {
$data[$key] = $val;
}
}
}
and i would use the '$val' values in the view. just by calling them as variables, like so
//in the view
echo $decoded
echo $firtname
... and so on

Answer 2

to check if new is empty or not, just
print_r($news);
or you can modify your view :
<?php if(!empty($new)): ?>
<?php foreach ($news as $news_item): ?>
<h2><?php echo $news_item['title'] ?></h2>
<div id="main">
<?php echo $news_item['text'] ?>
</div>
<p>View article</p>
<?php endforeach ?>
<?php else: ?>
Empty news
<?php endif; ?>
