Can't load a controller from a view, why? - El Forum - 11-14-2009

[eluser]gusst250[/eluser]
In one 'view' I want to include a 'controller' (which should be able to load new views itself).

I use the command:

Code:
$url = base_url();

$url .= "application/controllers/content.php";

include $url;

to do it.

I get this error message:
Fatal error: Class content: Cannot inherit from undefined class controller in /var/www/02/22/69/bestallarkompetens.com/www/application/controllers/content.php on line 3

the first 5 lines of content.php is:

Code:
&lt;?php 

echo '<br/>content<br/>';        //just to verify that the previous include worked

class Content extends Controller 

{

    function __construct()

content.php works fine when browsing to it manually, it's just when it is included in a view that this message appears.

Thankful for any help!

Controllers are meant to be the receiver of requests.

You could:

1. load the view file from the view or controller
2. use ajax to request

ok, so how do I do it?

This 'include' is meant to include content.php in a <div> at the page, to make the site dynamic.
I would then be able to load views right in to that <div>.

Points to previous answer------^

Or you could use a template library

Colin's template

Or you could use widgets.. see

Ok, solved this particular situation with a system of templates.

But I'm interested in how to implement these jQuery/ajax-requests into codeIgniter's $this->load-thing.

What is the corresponding jQuery/ajax-syntax, in a controller, of loading a view with:

Quote:$this->load->view('somefile');

Well there's none at the moment. It would via normal jQuery..

Hmm.. one moment..

Code:
<div id="container">

   <div id="sidebar">

   </div>

    <div id="main">

        <a id="trigger" href="blah.html">Click me</a>

    </div>

</div>

&lt;script&gt;

$(function(){

   $('#trigger').click(function(){

      $('#sidebar).load("&lt;?php echo site_url('controller/method');?&gt;");

   });

});

&lt;/script&gt;

Something like that but of course you can pass along data on trigger etc.

Code:
// controller

function method()

{

    if (is_ajax())

    {

        echo "I'm the sidebar content";

    }

}
