database driven codeigniter navbar - php

Question

I am new with CodeIgniter and have been told that it is the way to go.
I have read the user manual a few times now but don't seem to understand one thing which is I wanted to do a navbar driven from the database. I found a few posts on here saying about a method that I have implemented but no matter what I do, it just doesn't seem to work for me. what I have done so far:
Created a table with :
CREATE TABLE IF NOT EXISTS `app_routes` (
`id` bigint(20) NOT NULL auto_increment,
`slug` varchar(192) collate utf8_unicode_ci NOT NULL,
`controller` varchar(64) collate utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`),
KEY `slug` (`slug`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1;
Added to route.php file
$route[ 'default_controller' ] = 'home';
$route[ '404_override' ] = 'error404';
require_once( BASEPATH .'database/DB'. EXT );
$db =& DB();
$query = $db->get( 'app_routes' );
$result = $query->result();
foreach( $result as $row )
{
$route[ $row->slug ] = $row->controller;
$route[ $row->slug.'/:any' ] = $row->controller;
$route[ $row->controller ] = 'error404';
$route[ $row->controller.'/:any' ] = 'error404';
}
Set up a controller with:
<?php
class Home extends CI_Controller {
public function index()
{
$this->load->view('smooth/header.php');
$this->load->view('smooth/navbar.php');
$this->load->view('smooth/index.php');
$this->load->view('smooth/footer.php');
}
}
?>
In the database I have under controller home and as page contact
When I visit my site via my domain name only I see the frontpage but if I add the index.php/home to it I get nothing or index.php/home/contact nothing either
The path to my index.php files as situated in my domain/application/views/themes/smooth/index.php
Can anyone help with what I am missing please or what the problem is?

Answer 1

You didn't pass the routes to the view.
Without seeing the view in question I can't tell if there's an issue there, but you need to pass the data through like this:
$this->load->model('yourmodel');
$routes = $this->yourmodel->getRoutes();
$data = array(
'routes' => $routes
);
$this->load->view('smooth/header.php');
The database query goes in a model, so you will need to define that, and a method to return the data - here I've represented that model as yourmodel and the method to call as getRoutes. You should not, under any circumstances, be placing your database query in routes.php.
