Query and display result in CodeIgniter - php

Question

I have the following code that query and display the result from database.
Database
id title desc
1 BUILD The
2 BEAUTIFUL Use
The piece of code in model folder
<?php
class Portfolio_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_webinfo()
{
$query = $this->db->select('title')->from('webinfo')->where('id', 1)->get();
return $query->row_array();
}
}
?>
The piece of code in controllers folder
<?php
class Portfolio extends CI_Controller {
public function view($portfolio = 'home')
{
if ( ! file_exists(APPPATH.'/views/portfolio/'.$portfolio.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
$data['title'] = ucfirst($portfolio); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('portfolio/'.$portfolio, $data);
$this->load->view('templates/footer', $data);
}
public function __construct()
{
parent::__construct();
$this->load->model('portfolio_model');
$this->load->helper('url_helper');
}
public function index()
{
$data['webinfo'] = $this->portfolio_model->get_webinfo();
$this->load->view('templates/header', $data);
$this->load->view('portfolio/index', $data);
$this->load->view('templates/footer');
}
}
?>
The page that I want to display the data
<h2 class="intro-text text-center">
<strong><?php echo $webinfo['title']; ?></strong>
</h2>
However, I get the following error when I run the display page
A PHP ERROR WAS ENCOUNTERED
SEVERITY: NOTICE
MESSAGE: UNDEFINED VARIABLE: WEBINFO
May I know how should I go about editing the code to resolve the error?
Try 01
Controller
<?php
class Portfolio extends CI_Controller {
public function view($portfolio = 'home')
{
if ( ! file_exists(APPPATH.'/views/portfolio/'.$portfolio.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
$data['title'] = ucfirst($portfolio); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('portfolio/'.$portfolio, $data);
$this->load->view('templates/footer', $data);
}
public function __construct()
{
parent::__construct();
$this->load->model('portfolio_model');
$this->load->helper('url_helper');
}
public function index()
{
$data['webinfo'] = $this->portfolio_model->get_webinfo();
print_r($data['webinfo']);
/* $this->load->view('templates/header', $data);
$this->load->view('portfolio/index', $data);
$this->load->view('templates/footer');*/
}
}
?>
Model
<?php
class Portfolio_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_webinfo()
{
$query = $this->db->query("SELECT title FROM webinfo WHERE id = 1");
$result = $query->result_array();
return $result;
}
}
?>
view
<h2 class="intro-text text-center">
<strong><?php echo (!empty($webinfo[0]['title'])) ? $webinfo[0]['title'] : 'Empty Title' ;; ?></strong>
</h2>

Answer 1

Try this
In Model
public function get_webinfo()
{
$query = $this->db->query("SELECT title FROM webinfo WHERE id = 1");
$result = $query->result_array();
return $result;
}
In View
<h2 class="intro-text text-center">
<strong><?php echo (!empty($webinfo['title'])) ? $webinfo['title'] : 'Empty Title' ;; ?></strong>
</h2>
Note: If I'm right sometimes this $webinfo['title'] gives error and its work fine with with $webinfo[0]['title']
And there is way to write controller.
__construct
index()
then other all functions
EDIT 01
public function index()
{
$data['webinfo'] = $this->portfolio_model->get_webinfo();
print_r($data['webinfo']);
/* $this->load->view('templates/header', $data);
$this->load->view('portfolio/index', $data);
$this->load->view('templates/footer');*/
}

Answer 2

controller:
public function index()
{
$data['result'] = $this->portfolio_model->get_webinfo();
//$this->load->view('templates/header', $data);
//$this->load->view('portfolio/index', $data);
// $this->load->view('templates/footer');
print_r($data);
}
model
public function get_webinfo()
{
$this->db->select('*');
$this->db->from('pwebinfo');
$this->db->where('id',1);
$query = $this->db->get();
if($query->num_rows() ==''){
return 'failure';
}else{
$results = $query->result();
$result = $results[0];
return $result;
}
}
view
<h2 class="intro-text text-center">
<strong> <?php echo $result[0]->title; ?> ?></strong>
</h2>
