Hey,

I am new to code igniter and want to know how I use includes.

I have started building a web page but don't want to replicate every line of code so includes are the best answer, but how do I use them with code igniter?

Thanks

You can call functions from within your controller like $this->functionName(); such as:

Code:
&lt;?php

    class Blog extends Controller {

        public function index() {

            echo 'hello world!';

        }

        public function register() {

            $this->index(); // output: hello world

        }

    }

?&gt;

I meant in terms of headers and footers. Thanks though.

Ah. If you want specific functions to point to specific views you use something like this:

Code:
&lt;?php

$array=array('var'=>'Headers','var1'=>'Footers');

$this->load->view('view_file_name',$array) // dont include the .php extension

?&gt;

Remember the array elements become variables, so to get the array contents you use: echo $var;

Yeah, just create views for your header and footer files, then call them in your controllers.

The way I do it is to have all output directed to a single view file, which includes a number of generic "component" files. In the controller, I then pass an array of files which contain the *actual* page content (i.e. stuff that is specific to the particular page you're viewing) and one of the "component" files contains a foreach loop on that file list to recursively include the files in the list.

File Structure:

Code:
views/

- index.php (single view file)

- global/

--- header.php (globally-included page header)

--- footer.php (globally-included page footer)

--- content.php (globally-included page "content")

- content/

--- controller1/

----- controller1_action1_init.php

----- controller1_action1_error.php

----- controller1_action1_done.php

--- controller2/

----- controller2_action1_init.php

----- controller2_action2_init.php

Controller (extract):

Code:
function index()

{

  $this->data['file_list'][] = $view_path . '/content/controller1/controller1_action1_init.php';

  // if we want to add more content, we can do... this allows us to separate

  // the page into manageable blocks

  $this->data['file_list'][] = $view_path . '/content/controller1/controller1_action1_done.php';

  // load the view

  $this->load->view('index', $this->data);

}

Single view file:

Code:
&lt;html&gt;

&lt;?php include_once('global/header.php'); ?&gt;

&lt;?php include_once('global/content.php'); ?&gt;

&lt;?php include_once('global/footer.php'); ?&gt;

&lt;/html&gt;

Content file:

Code:
&lt;?php

  foreach($file_list as $file)

  {

    include_once($file);

  }
