CI update from 1.7 to 2.0 getting Fatal error: Class 'CI_Controller' not found in CodeIgniter.php on line 210

Dont forget to change your Constructors to the new ones also.

Code:

//old way
class MyClass {

    function MyClass()
    {

    }
}

// New way constructor
class MyClass {

    public function __construct()
    {
        parent::__construct();
    }
}

Thanks for the update, I'm looking into all my constructor files now.

I saw your comment on another problem on this forum where you said that the library extensions come in the library folder correct? I have 3 extended classes, MY_Session, MY_Email and MY_Security and they are in the application/libraries folder. Just want to confirm this is correct.

Also I noticed that in my system/core/codeigniter.php around line 220 there's following code

Code:

require BASEPATH.'core/Controller'.EXT;
function &get;_instance()
{
  return CI_Controller::get_instance();
}

When I move the 'require ..' line to the top of my page I dont get the ci_controller error anymore. Now I get Fatal error: Call to undefined method CI_Security::SetLastPage()

It seems like anything I change keeps switching between these two error messages.

BTW MY_Security looks like this

Code:

class MY_Security extends CI_Security{

private $CI = null;

// TODO: ensure it's admin/user safe

/**
  * __construct()
  *
  * Constructor
  * Load the classes
  *
  * @access public
  * @param none
  * @return void
  */
public function __construct()
{
  $this->CI =& get_instance();
  
  $this->CI->load->library('encrypt');
  $this->CI->load->library('validation');
}

I get a Call to a member function library() on a non-object on the load library line

You won't be able to use get_instance() in your extended Security file, because it is loaded before the controller exists (which is what the function is looking for, and why the error comes from that line of CodeIgniter.php).

[eluser]InsiteFX[/eluser]

Code:

public function __construct()
{
    // you need to add this when extending all CI core/libraries.
     parent::__construct();
}

Also Aken is correct you cannot use get_instance, because CI is not loaded yet.

After a couple of days of changing code and trying things I've got the front page displaying correctly. However the other pages won't come up and return a 404. I think it's the routing..

Anyhow thanks a lot for your help,
