I just read the wiki article http://codeigniter.com/wiki/layout_library/

and tried to do this at my application but I get a error
Fatal error: Call to a member function on a non-object in /home/worldofm/public_html/apartments/system/application/controllers/chisinau.php on line 12

When I tried to find out what’s the problem I saw that load object doesn’t exist in the controller

chisinau Object
(   [_ci_ob_level] =>
  [_ci_view_path] =>
  [_ci_is_php5] =>
  [_ci_is_instance] =>
  [_ci_cached_vars] => Array
      (
      )

  [_ci_classes] => Array
      (
      )

  [_ci_models] => Array
      (
      )

  [_ci_helpers] => Array
      (
      )

  [_ci_plugins] => Array
      (
      )

  [_ci_scripts] => Array
      (
      )

  [_ci_varmap] => Array
      (
        [unit_test] => unit
        [user_agent] => agent
      )

  [_ci_scaffolding] =>
  [_ci_scaff_table] =>
)

What is the problem?

can you post the code in your controller chisinau.php ?

can you post the code in your controller chisinau.php ?

here it is

<?php
class Chisinau extends Controller {
  function Chisinau()
  {
      $this->load->library(‘layout’, ‘layout_main’);
  }
 
  function index()
  {
      $this->layout->view(’/chisinau/index’, $data);   
      test();
  }
}
?>

What is the function test() doing in your index() method? You are calling a function that doesn’t exist. You also have the variable $data being passed to $this->layout->view(’/chisinau/index’, $data); when you haven’t assigned anything to that variable.

function test is in the helper which loads automaticaly…

I think data variable desn’t have anything common with this error

The problem is that I can’t load libraries

and as the instructions say on the Wiki you have the Layout.php file located in your “/application/libraries/” folder?

of course

I also tried to use uri class and get the same error
$product_id = $this->uri->segment(1);

That’s true, but it will cause an error once you get the other one fixed and it remains unassigned. Just pointing that out since I noticed it while looking through your controller code.

thank you

Hmm…this is very strange. I’m currently using the exact same library on a project and it’s working perfectly. Your code looks fine to me also. (scratches head)

Is there another way to get controller and view name?

I think somenthing doesn’t work :(

When I try to load any class i get this error…

Is there another way to get controller and view name?

What do you mean? There is of course the default way that CI loads views for controllers. Which is as follows:

Or are you looking for another way?

Were you able to load your controllers before using the Layout Library?

I mean variables in uri name…

If I comment everything connected with layout library everything works fine.

But I can’t load default classes.

You need to call parent::Controller() in the constructor

[quote author=“emperius”]I mean variables in uri name…

I’m sorry but I’m still not understanding exactly what you mean or are trying to accomplish. Could you give an example of what you are trying to do?

[quote author=“emperius”]But I can’t load default classes

Which default classes are you trying to load?

D’oh, but of course, how did I miss that one. Good eye there Colin.

Emperius, that’s a good point Colin raised. As it says in the documentation, if you have a constructor (ie. a function with the same name as the class or in PHP5 __construct() ) then you must have “parent::Controller() in it. So your controller will now look like this:

Once again thanks for pointing that out Colin.

Does that solve your problem now Emperius?
