Extending core Controller class

[eluser]gabe[/eluser]
Hi there

I just wanted to extended that core class. My class prefix is MY_ and I created a file called MY_Controller.php in /system/application/libraries/, it contains the following: (I'm trying to enable profiling for all controllers without altering the controllers):

Code:

<?php
class MY_Controller extends Controller
{
    function __construct()
    {    
        $this->output->enable_profiler(TRUE);
    }
}
?>

It doesn't work I probably have it all wrong. I'd be glad of some advice.

Regards

Code:

<?php
class MY_Controller extends Controller
{
    function __construct()
    {  
        parent::Controller();  
        $this->output->enable_profiler(TRUE);
    }
}
?>

Thanks for your prompt reply. I added the

Code:

parent::Controller();

but it still won't work. I even placed an exit(); statement in my version and the app didn't exit, somehow it isn't being read?

I'd think the method you outlined should work not sure why it doesn't.

Here is one way to get it to work:

application\libraries\MY_Controller.php

Code:

class Public_Controller extends Controller {
    function Public_Controller() {
        parent::Controller();
        $this->output->enable_profiler(TRUE);
    }

controller\test.php

Code:

class Test extends Public_Controller {

  function __construct() {
        parent::Public_Controller();
    }
    
    function index ($offset = 0) {
     echo $offset;
    }
}

this might be somehting i came up against... am i right in saying that you are on php4? php5 support the __construct() whereas for php4 you needed to mack the function the same name as the class, in your case:

Code:

<?php
class MY_Controller extends Controller
{
    function MY_Controller()
    {    
        parent::Controller();
        $this->output->enable_profiler(TRUE);
    }
}
?>

however, i found that i could not get the profiler to enable by default no matter what i did. only on a per controller basis. Someone might be able to suggest somehting here?

What I suggested will work, every controller that extends Public_Controller would have the profiler enabled. It would work using __construct() too.

application\libraries\MY_Controller.php

Code:

class Public_Controller extends Controller {
    function __construct() {
        parent::Controller();
        $this->output->enable_profiler(TRUE);
    }

controller\test.php

Code:

class Test extends Public_Controller {

  function __construct() {
        parent::__construct();
    }
    
    function index ($offset = 0) {
     echo $offset;
    }
}

will this work on multiple levels of controllers.

### strike through... a typo was causing my levels not to work... although i am still experiencing the __construct issues..

I have found you can't use __construct() when extending CI, regardless whether you are running PHP4 or PHP5. At least for me, on xampp.

Since I develop on this machine and upload to live sites (without trying to change much), I've yet to try it on a live site.

[eluser]gabe[/eluser]
Thanks to all for the replies.

I am using the latest PHP5 on an Ubuntu Gutsy server. So the __construct problem seemed unlikely. Also, with regards to the post by 'ontguy' I think your solution sounds reasonable, but not for me.

I wanted to extend the the CI_Controller to enable profiling globally on the dev environment, this way when I copy to the live site I can simply exclude my controller and profiling is disabled. If I make changes to each controller then they would end up on the live site and I have to keep manually disabling profiling.

Thanks to Michael Wales, it seemed possible, but even changing from __construct() didn't help, I've now got the following in system/application/libraries/MY_Controller.php:

Code:

<?php
class MY_Controller extends Controller
{
    function MY_Controller()
    {    
        parent::Controller();
        $this->output->enable_profiler(TRUE);
    }
}
?>

[eluser]nevsie[/eluser]
and how are you referencing MY_Controller from all your other controllers?
