i want to put login form in navigation(template) so that it will be shown in all the pages.
and will check username and password in database without going to other pages. if failed, an error will be shown in the nav and if success, the page will be reloaded again with specific costomizations. please tell me how with code and details.
i have these parts in my template:
header
nav
footer
and content that will be added in current controller
i wanna do this in each controller:
$this->load->view('templates/header');
$this->load->view('templates/nav');
$this->load->view('related_view');
$this->load->view('templates/footer');
but my navigation should contain a login form which will not go to another page by submitting.
I usually do something like this:
<?php
$this->load->view('templates/header');
if ($this->user_model->isLoggedIn())
{
// Logged-in users should see this view
$this->load->view('templates/nav-registered');
}
else
{
// Guests should see this
$this->load->view('templates/nav-guest');
}
$this->load->view('related_view');
$this->load->view('templates/footer');
You'll thank yourself if you override the Loader class to grab your header/footer for you automatically, not having to code this in EVERY controller method. Just a thought..
use session to check loged user, and put this on the nav view, but first make sure you have session loaded from auload or from your controller
if($this->session->userdata('user_loged')){
//code to put some navigation when use is loged
}else{
//code to put login form
}
The solution I found is to extend the Controller class. So In this case we should make an extended controller (for example MY_Controller) and put the dynamic action (here authentication) in it as a method.
Then we should extend this self-made controller in each of our controllers , so authentication in the template would be simply handled.

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 different pages/controllers.
Is it better to call the views from within the main controller's view? If so, how? Or should I call the 'mini view' from the controller and thus pass the view's code to the main view?
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!
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.
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);
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);
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');
$this->load->view('index');
}
}
In the controller
controller
<?php
public function view($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');
?>
I have a route which redirects to a controller which tells view to show. But how can I go to a particular part of the page. Let me Explain:
I am using fullpage.js library to create a page breakpoints.
for example: /home#firstPage , /home#secondPage and so on. When I am redirected to /home I would like to go to a particular section of the page. All I need is a way to enter #3rdPage in url.
Where and How do I put this to see it action?
my Routes
Route::get('/home_done', ['as' => 'home_done','uses' => 'HomeController#home']);
my Controller
public function home()
{
return view('home_done');
}
I would like to do something like:
return view('home_done#3rdPage');
You should setup a new function and route to redirect the users to correct page after executing your logic:
public function home()
{
return view('home_done');
}
public function step_3()
{
// do something and redirect
return redirect('home_done#3rdPage');
}
Using view don't work since you are loading a file, not the page.
You need change your behavior in JS, when a user comes to your page without a # consider it equal of #firstpage.
and in your html manage all over pages by properly generate urls with #what_you_need.
in your blade example:
firstpage
//OR
firstpage //because this is the same for your JS
secondpage
or blade syntax
firstpage
//OR
firstpage //because this is the same for your JS
secondpage

I'm trying to add a view just a simple contact page, I already have other views.
Here's what I've done so far:
added 'contact' in my routes file here
$route['^(?!/|site|ajax|gallery|contact).*'] = "site/view/$1";
added contact.php to my application/views folder
added contact() to my site controller (whole controller here http://pastebin.com/CCjjrV8R)
function contact() {
$this->load->model('Site_model');
$this->load->view('contact');
}
When I visit the correct url for the view (domain.com/contact), I get a page with partial content and "404" in the
Can anyone see a problem? This is very puzzling.
I don’t think you need the view part of the URL in the route?
I am using codeigniter for a project. I set controller A as my default controller in routes.php. So in this controller A it will load my home page.
If I want to access another view from the homepage for example about or contact, how do I go about doing it??
Example:
<a href="http://yoursite.com/yourcontroller/yourfunction">About Page
Now you have yourcontroller that has the yourfunction in it, from within this function you can load the view for about page, like:
function yourfunction() {
$this->load->view('your_about_view_page_name");
}
And that shall work. Hope it helps
