Load new Controller from within Controller / View? - El Forum - 06-12-2010

I'm using a template to display the header, body, and footer. These are all views. Within the header there is the User_info view for displaying the Sign In / Sign Up or if logged in already the customary logout / control panel display. At present within the User_info PHP view i have IF statements and checks for cookie.
TO me the User_info display should be a controller which then decides what view to show. From within my home page controller or template view is it possible (and proper) to load the User_info controller class? Would i use $this->load->library('controllers/User_info')?

Since the logged in/not logged in status is something that you would generally want to see on every page, the best thing to do is extend the controller class by making a MY_Controller.

Hi quantis and welcome to the CI forums.
Have a read of [url="http://ellislab.com/forums/viewreply/559962/"]this message[/url] and perhaps go back and read that entire thread for some context.
Is this the kind of thing you're wanting to do?
You might want to read up on [url="/wiki/MY_Controller"]extending the core controller[/url] in the wiki, and also in the [url="/user_guide/general/core_classes.html"]user guide[/url].

Most authentication controllers will use a library for this kind of thing. You then can load the library from any controller/view for any controller.
Code:
// application/libraries/User_lib.php
class User_lib {
function User_lib(){
//Initialize variables here if you have to
}
function display_login_form(){
if($this->session->userdata('logged_in') == TRUE){
$form = anchor('user/logout'); // display logout link
}else{
$form = form_open('user/login');
$form .= form_label('Username','username') . form_input('username',set_value('user'));
$form .= form_label('Password', 'password') . form_password('password');
$form .= form_close();
}
return $form;
}
}
//In any controller or view
$this->load->library('User_lib');
echo $this->User_lib->display_login_form();This assumes you have loaded the session class and form helper somewhere.

Thanks guys. I was leaning towards libraries as pickupman suggested. All of this information has been very enlightening.
