Best method of including views within views in CodeIgniter

Question

I\'m starting a large codeigniter project and would like to try to create some reusable \'mini\' views for snippets of content like loops of data which may be displayed on d

Answer 1

This a simple way of including views within views.there is no need to load views in advance.just pass view path to other view.

In your controller use this:

$data['middle'] = 'includeFolder/include_template_view';  //the view you want to include
$this->load->view('main_template_view',$data);  //load your main view

and in main_template_view you can include other views :

$this->load->view($middle);

Answer 2

METHOD 1

I use this method into my view to insert the include view where I want

$this->load->view('include/include_view');

METHOD 2

or in the controller you can load more than a view like this:

$this->load->view('header_view');
$this->load->view('list_view');
$this->load->view('footer_view');

No one method is better than the other, it depends if you have to pass some data (in this case use method2) or if you want to include a view in a specific part of your main view (in this case is better to use method1)

METHOD 3

Passing data to your include view by your main view

into your controller:

$data['title'] = "Title";
$this->load->view('main_view',$data);

in your view

$data2['title'] = $title;
$this->load->view('include/include_view',$data2);

If you want to pass entire data to your include view you can do in this way: in your controller:

$data['nestedView']['title'] = 'title';

in your view

$this->load->view('includes/included_view', $nestedView);

Answer 3

In the controller

controller

<?php
    public function view($page = NULL)
        {
          if ( ! file_exists(APPPATH.'views/pages/'.$page.'.php'))
        {
                 $data['title'] = ucfirst($page); // Capitalize the first letter
                // Whoops, we don't have a page for that
                show_404();

        }

        $data= array(''); 
        $data['title'] = ucfirst($page); // Capitalize the first letter 
         $data['page_layout']='pages/'.$page;    
         $this->load->view('page_layout', $data);
        }
?>

In the Views folder create a page called page_layout.php

page_layout.php

//This is where you set the layout to call any view through a variable called $page_layout declared in the controller//

 <?php
     $this->load->view('header');
     $this->view($page_layout);
     $this->load->view('footer');
  ?>

Honestly I prefer to do this by having template views then loading that with the necessary data from the controller, it means a lot less repeated code and follows the DRY concept better than loading views from views. Especially for things like headers, footers and menus.

So my template view would look something like this:

template.php

$this->load->view('header',$title);
$this->load->view('sidebar',$sidebar_content);
$this->load->view('main_content',$main_content);
$this->load->view('footer');

Then in my controller I pass the data required to the template like this:

$data['title'] = 'Home Page';
$data['sidebar_content']='pages/standard_sidebar';
$data['main_content'] ='pages/my_home_page'; 
$this->load->view('template',$data);

There are a number of benefits to doing it this way. First is I can have multiple templates, for example I have, in my case, two main ones, one for full page views without a sidebar and one for pages with a sidebar, I also call an if statement to decide which header to include, the regular one or the one with the admin menu in it.

Yes I could include the header, sidebar and footer in every main view page, but that ends up in a ton of duplicate code. And what happens if for example I want all my pages to have something new, some other small snippet? Using templates I add the snippet to the appropriate template and it's done. Going the other route I find every page and add the snippet view there, it's the equivalent to having CSS in the page in my opinion, wasteful and not ultimately maintainable.

In my opinion for solve in more efficient way this problem I have done so:

You create a new helper (in application/helpers) with name (es. common_helpers.php, the underscore is important). In this file, you put all the functions for example build pieces of html in common.

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

    function getHead(){
    require_once(APPPATH."views/common/head.php");
    }   

    function getScripts(){
    require_once(APPPATH."views/common/scripts.php");
    }

    function getFooter(){
    require_once(APPPATH."views/common/footer.php");
    }

In your controller you call only one view in respect of MVC and call the functions from your custom helper.

class Hello extends CI_Controller {

   public function index(){
       $this->load->helper('common');
       $this->load->view('index');   
   }

}

Views within other views are called Nested views. There are two ways of including nested views in CodeIgniter:

1. Load a nested view inside the controller

Load the view in advance and pass to the other view. First put this in the controller:

<?php
// the "TRUE" argument tells it to return the content, rather than display it immediately
$data['menu'] = $this->load->view('menu', NULL, TRUE);
$this->load->view ('home', $data);
?>

Then put <?=$menu?> in your view at the point you want the menu to appear.

2. Load a view "from within" a view

First put this in the controller:

<?php
  $this->load->view('home');
?>

Then put this in the /application/views/home.php view:

<?php $this->view('menu'); ?>

<p>Other home content...</p>

About best method, I prefer the 1st method over 2nd one, because by using 1st method I don't have to mix up code, it is not like include php. Although indirectly both are same, the 1st method is clearer & cleaner than 2nd one!
