Question

Update:

I have tried Sheldon's code below but I have struck a couple of issues:

  1. When using the line $this->load->view($page->template, array('content' => $page->content), TRUE);Unable to load the requested file .php but if I change it to $page->content it works fine.

  2. When I place the index functions into my other controllers it still loads the default home controller despite what the uri segment is set to. How do I adjust the model for this to work?

Original Question:

I have a template.php file which houses my main site structure. Suppose I have a page called 'home'. I would like to set the $title and the $content data from the database.

I have set a view for each page and also a controller. I have tried:

$this->cms_pages->name;

This produces nothing. I know I need to get the URI segment but because I am using /$sales->name I am unsure if I have to change it to $sales->id for this to work. I would like to get it by the name. Best practices are also important.

Is there a way that I could do something like: $this->cms_pages->id->1->name?

Model

function getCMSPages() {

    $query = $this->db->get('pages');
    if($query->num_rows() > 0) return $query->result();
}

Template

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Home extends CI_Controller {

public function index()
{
$data['cms_pages'] = $this->navigation_model->getCMSPages();
$data['title'] = 'Ccho';
$data['content'] = $this->load->view('home', NULL, TRUE);
$this->load->view('template', $data);
}
}

Template 

 $stylesheetCSS = array('href' => 'includes/css/style.css', 'rel' => 'stylesheet',   'type' => 'text/css', 'media' => 'print');

echo doctype('html5');
?>
<head>

Solution

As @davzie said;

Model

function getCMSPage($page_name = '') {

    if(!$page_name) $page_name= 'home'; // home be default.    
    $this->db->where('name', $page_name);
    $query = $this->db->get('pages', 1);
    if($query->num_rows() == 1) return $query->row();
}

Controller

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Home extends CI_Controller {

public function index()
{
$page = $this->navigation_model->getCMSPage($this-uri->segment(1)); // pretend the first segment in your URI is the page you want.
$data['cms_pages'] = $this->navigation_model->getCMSPages();
$data['title'] = $page->name;
$data['content'] = $this->load->view($page->template, array('content' => $page->content), TRUE);
$this->load->view('template', $data);
}

}

OTHER TIPS

You might want to consider having a function that gets the details of a page by its name. This in-turn would run a function like getIdByName($page_name = false)

From there you would have the ID to pull from the database and get the correct page.
