I uses DX Auth and Template Library http://www.williamsconcepts.com/ci/codei.../template/

I need set up a layout, there there is a user area that is displayed only for logged users. I have created the curresponding view in views/user_area.php and this view shows logged users name.

For getting this I need to setup the following code in every controller constructor.

Code:
$this->load->library(array('template', 'DX_Auth'));

        $data ['user_name'] = $this->dx_auth->get_username(); 

        $this->template->write_view('user_area','user_area', $data);

How can I make this automated? editing the Template library code or setting up different layous for login and non-login pages?

this is my template layout file

Code:
&lt;html&gt;

   &lt;head&gt;

      &lt;title&gt;&lt;?php echo $title; ?&gt;&lt;/title&gt;

      &lt;link rel="stylesheet" type="text/css" href="&lt;?php echo base_url();?&gt;css/template.css" /&gt;

   &lt;/head&gt;

    &lt;body&gt;

        <div id="wrapper">

            <div id="header">

                <div id="user_area">

                    &lt;?php echo $user_area;?&gt;

                </div>

                &lt;?php echo $header; ?&gt;

                <div id="tab_area">

                    &lt;?php echo $tab_area;?&gt;

                </div>

            </div>

            <div id="main">

                <div id="content">

                    &lt;?php echo $content; ?&gt;

                </div>

            </div>

            <div id="footer">

                &lt;?php echo $footer; ?&gt;

            </div>

        </div>

    &lt;/body&gt;

&lt;/html&gt;

Extend the Controller.

Use MY_Controller, put the code that you need repeating in the mentioned Controller.

We really, as a community, need to generate a de facto response to this question that comes up 5 times a day in 600 different flavors. The wiki touches on it in a few places but I don't think it's clear enough. Maybe I'll tackle that tonight or tomorrow.

@flaky, @Colin Williams Thanks
Got some stuff from here http://codeigniter.com/wiki/Extending_Co...tionality/

But still some confusion, i need to move my common code to MY_Controller? is it right to edit a file in system folder?

No. Don't touch system code. MY_Controller would exist at application/libraries/MY_Controller.php. Most of your global logic will live in MY_Controller's constructor function, typically getting data and making it available to views through $this->load->vars() or by writing it to a template region.

Consider this

Code:
class MY_Controller extends Controller {

   function MY_Controller()

   {

      parent::Controller();

      $data['user_name'] = $this->dx_auth->get_username(); 

      $this->template->write_view('user_area','user_area', $data);

   }

}

And then be sure your Controllers in application/controllers extend MY_Controller, not just Controller (unless you WANT to bypass what MY_Controller does). That's the gist of it.

As i don't want each unnecessary extra master page template features of MY_Controller as I already have a robust Template Library, I decided to write my own APP_Controller.php and put it in system folder

Code:
&lt;?php

class APP_Controller extends Controller {

     /**

     * The APP_Controller constructor method.

     */

    function __construct(){

        parent::Controller();

        $this->load->library(array('template', 'DX_Auth'));

        $data ['user_name'] = $this->dx_auth->get_username(); 

        $this->template->write_view('user_area','user_area', $data);

    }

}

and

Quote:class Examples extends APP_Controller

Thes result was

Code:
Fatal error: Class 'APP_Controller' not found in C:\wamp\www\ci\system\application\controllers\examples.php on line 2

Makes no sense. And, how do you suppose your APP_Controller file would load? You didn't follow any of CI's naming and file location conventions.

Quote:I decided to write my own APP_Controller.php and put it in system folder

CI looks in application/libraries for filenames that match those in system/libraries, but prefixed with 'MY_' (a prefix you can change in config if you want) and loads those files automatically. You can keep your APP_Controller in the system folder if you want, but you'll have to include() or require() it manually

I just got that My APP_Controller is not loading ;-)

I Tried the code

Code:
class MY_Controller extends Controller {

   function MY_Controller()

   {

      parent::Controller();

      $data['user_name'] = $this->dx_auth->get_username(); 

      $this->template->write_view('user_area','user_area', $data);

   }

}

and

Code:
&lt;?php

class Opportunities extends MY_Controller

{

    function Opportunities()

    {

        parent::Controller();

        $this->load->helper(array('url', 'form'));

        $this->load->library(array('Form_validation','template', 'DX_Auth'));

    }

does not fire the code inside MY_Controller's constructor

But the below combination, code without MY_Controller works

Code:
&lt;?php

class Opportunities extends Controller

{

    function Opportunities()

    {

        parent::Controller();

        $this->load->helper(array('url', 'form'));

        $this->load->library(array('Form_validation','template', 'DX_Auth'));

        $data ['user_name'] = $this->dx_auth->get_username(); 

        $this->template->write_view('user_area','user_area', $data);

    }

[eluser]flaky[/eluser]
maybe this is the culprit

Code:
&lt;?php

class Opportunities extends MY_Controller

{

    function Opportunities()

    {

        parent::Controller();//this here

change it to

Code:
&lt;?php

class Opportunities extends MY_Controller

{

    function Opportunities()

    {

        parent::MY_Controller();

01-18-2010, 05:27 AM

[eluser]Mithun[/eluser]
yea that was, just changed to

Code:
&lt;?php

class Opportunities extends MY_Controller

{

    function Opportunities()

    {

        parent::__construct();

    }
