Codeigniter Library problem

[c_pattle]

I have a problem where in a controller constructor I can load the codeigniter libraries such as session and cart but I can never load any libraries that I've written.  Everytime I do it says that it is undefined.  Does anyone know what might be causing this?  Thanks

Hmmm. let me get my crystal ball out....

Sorry.  So for example if I do

 

class Homepage extends CI_Controller
{
    
    function Homepage()
    {
        parent::__construct();
        
        $this->load->library('layout');
    }
}

 

The library doesn't seem to load because I can't access any of the method in that libary.  But if I was to load the library in another function that wasn't the contoller it works fine

$this->load->library('layout');
if (!isset($this->layout)) $this->layout = get_instance()->load->library('layout');
var_dump($this->layout);

 

What does this tell you?

class Homepage extends CI_Controller {
    
    public function __construct()
    {
        parent::__construct();
        
        // Assuming layout.php or Layout.php  is located in /application/libraries/
        $this->load->library('layout');
    }

    public function index()
    {
          $whatever = $this->layout->some_method();
    }
}
