Hey everyone!
I have 10 controllers in my codeigniter web application.
I want to load header.php and footer.php views by default, but only in 8 cases.
Other 2 cases i want to load no view.

How can I do it?
Add

Code:

if($load_templates === TRUE)
{
   $this->load->view('header');
   $this->load->view('footer');
}

this code to

Code:

CI_Controller

constructor, and then call

Code:

parent::__construct($load_templates);

?
