Upgrade to 2.0.2 from 1.7.2

[eluser]mabright[/eluser]
Sorry if I missed a link or post with detailed information for upgrading from 1.7.2 to 2.0.2.

I do not have a system or core folder in my 1.7.2 setup, can't remember if I renamed some folders, it's been awhile since I have done any coding.

How do I properly upgrade from 1.7.2?

I actually just need to know where the files in the core folder should go.

Any CI library extensions, e.g. MY_Controller.php MY_Loader.php, which were originally in "libraries", you must move to the "core" folder in 2.0.

All Controllers now extend CI_Controller
All Models now extend CI_Model

If the library you are extending is in system/core then your library goes into application/core
If the library you are extending is in system/libraries then your library goes into application/libraries

If you use a MY_Controller it may not work! So you need to add this...
application/config/config.php - to the bottom of the config file.

Code:

/*

|  Native Autoload - by Phil Sturgeon.

| Nothing to do with config/autoload.php, this allows PHP autoload to work
| for base controllers and some third-party libraries.
|
| If using HMVC you do not need this! HMVC will autoload.
|
| Place this code at the bottom of your application/config/config.php file.
*/
function __autoload($class)
{
    if (strpos($class, 'CI_') !== 0)
    {
        @include_once(APPPATH . 'core/' . $class . EXT);
    }
}

I made all the updates (thanks for the replies) but now all my pages which previously worked all error with "Fatal error: Call to undefined method CI_DB_mysql_driver::where() in ....../libraries/Session.php on line 201"


I am also now getting error "Fatal error: Call to undefined method CI_Controller::Controller() in ". I use a MY_Controller but I already moved it to the core folder as suggested.

I am also now getting error "Fatal error: Call to undefined method CI_Controller::Controller() in ". I use a MY_Controller but I already moved it to the core folder as suggested.

I am experiencing the same problem which is caused by the following lines:
$CI =& get_instance(); in my extended core class (MY_Lang)

see my post in the main forum.

Make sure you use the above autoload code!

application/core/MY_Controller.php

Code:

class MY_Controller extends CI_Controller {

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

I tried the autoload and also the things described in the other thread but I still get this error, it is slightly diffrent to the one here. (I tried 2.0.2, 2.0.1 and 2.0.0 and the error applies to all those versions). I am confused.

Now here the thing (completly new/clean Codeigniter 2.0.0)

This works (application/core/MY_Lang.php):

Code:

class MY_Lang extends CI_Lang {

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

    }

This does not (application/core/MY_Lang.php):

Code:

class MY_Lang extends CI_Lang {

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

        $CI =& get_instance();

    }

I get this error for line 210 in CodeIgniter.php

Fatal error: Class 'CI_Controller' not found in system\core\CodeIgniter.php on line 210

... which refers to the following lines:

Code:

require BASEPATH.'core/Controller'.EXT;

    function &get;_instance()
    {
        return CI_Controller::get_instance(); // this is line 210
    }

Not my script fails to load the CI_Controller but the CodeIgniter.php Core File...

Did you copy over the new index.php file?

sure.
