dynamically page load using codeigniter - codeigniter

Question

helow, I am a newbie in codeigniter. I want to load my pages into my view dynamically. That means, Using a function.
For example i have 4 page home, about, contact, info. In my my view folder I have created a base layout where i include header and footer which is same for all those pages. now i want when i click those page link it just load into content body without loading full page. Using CI normal procedure i can do it. which is
function home(){
$data['main_content'] = 'home';
$this->load->view('template/layout', $data);
}
function about(){
$data['main_content'] = 'about';
$this->load->view('template/layout', $data);
}
but i want to create a function which call this pages into a single function for example,
function pageload($page){
}
this function check that requested file either exits or not exist. if exist it load the page otherwise load "page not found" 404 error page. How can I make it...plz help.
My view file is:
<nav>
<ul class="sf-menu">
<li class="current"><?php echo anchor('home/index', 'Home');?></li>
<li><?php echo anchor('home/amenities', 'Room & Amenitis');?></li>
<li><?php echo anchor('home/reservations', 'Reservations');?></li>
<li><?php echo anchor('home/photos', 'Photographs');?></li>
<li><?php echo anchor('home/pakages', 'Pakages');?></li>
<li><?php echo anchor('home/explore', 'Explore');?></li>
<li><?php echo anchor('home/contact', 'Contact');?></li>
</ul>
</nav>
And Controller:
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Home extends CI_Controller{
function __construct(){
parent::__construct();
}
function pageload($page){
$data['main_content'] = $page;
$this->load->view('template/layout', $data);
}
}
?>

Answer 1

You can do something lilke this
function pageload($page){
$data['main_content'] = $page;
$this->load->view('template/layout', $data);
}
if u dont want to show controller_name/pageload in url then in application/config/routes.php
add an array
$route['(home|about_us|other_page|another_page)'] = 'controller_name/pageload/$1';
and to load your 404 page just go to the application/config/routes.php
find this line $route['404_override'] and set its value to snything u want like
$route['404_override'] = 'page_not_found';
then in your controller just add a controller named page_not_found.php and load ur desired 404 custom view from that controller.

Try this function i think this will help you
function build_view($flake) {
$this->data['content'] = $this->load->view($flake, $this->data, TRUE);
$this->load->view('header', $this->data);
}
after you add this you need to add to other function like in index function
function index(){
$this->$data['main_content'] = $page;
$this->build_view('template/layout.php')
}
