[SOLVED] My_Controller ?
#1

[eluser]solid9[/eluser]
Hi guys

Is creating My_Controller is good only for extending Native Libraries?

Or can I use it as ordinary controller?

What's the right way to name the My_Controller file?

Thanks in advanced.

This is what I did so far,

Code:
class My_mother extends CI_Controller
{
  function __construct()
  {
   parent::__construct();

  }
  
  function index()
  {
   echo 'Mother ship';
  }
}

And I name the file mother.php

But it show some error and the error is,
Code:
Message: Cannot modify header information - headers already sent by (output started at /home/struhi/public_html/thefml.org.uk/secret/application/controllers/mother.php:13)

You should follow the directions exactly in the link exactly. The controller needs to be named MY_Controller in order for it to be extended.

You should then return the data you will want to use in controllers you extend from the MY_Controller.

So your MY_Controller file name would be MY_Controller.php as shown.

Then the extended controllers operate as normal controllers, but for things you need site wide in all controllers, you can put that in the MY_Controller. Stuff like session management, site settings stuff etc.

Thanks dude I did not noticed that.

anyway here is the updated class,
Code:
class MY_Primary extends CI_Controller
{
  function __construct()
  {
   parent::__construct();

  }
  
  function index()
  {
   echo 'Primary';
  }
}

I also saved as MY_Primary.php

And I called it in the URL,
Code:
http://thefml.org.uk/secret/primary/

also like this,
Code:
http://thefml.org.uk/secret/primary/index/

and also like this,
Code:
http://thefml.org.uk/secret/index.php/primary/

But nothing happened.

It says,
Code:
404 Page Not Found

why?

[eluser]solid9[/eluser]
I tried calling it in the URL like this below,
Code:
http://thefml.org.uk/secret/MY_Primary/index/

Is that the right way to call it in the URL?

If yes, then I have error below,
Code:
Message: Cannot modify header information - headers already sent by (output started at /home/struhi/public_html/thefml.org.uk/secret/application/controllers/MY_Primary.php:19)

Problem solved.

Solution,
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Primary extends CI_Controller
{
  function __construct()
  {
   parent::__construct();

  }
  
  function index()
  {
   echo 'Primary';
  }
  
  function play()
  {
   echo 'Hello Foot Ball';
  }
  
}

I have forgot this part,
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

You still didn't do it right because you didn't follow the guide exactly, which is important.

Its called MY_Controller, not MY_Primary, and it gets put in /application/core/MY_Controller.php

Also, you don't call it directly. It is automatically loaded when you call a controller. Its just a way to add methods that will be available to all controllers, that extend MY_Controller.

Then, for your own controllers, they extend MY_Controller, instead of CI_Controller.

If you follow the guide exactly, it will work. If you alter it, it won't.

You will also have problems like you are having with the "cannot modify headers" if you echo from a base controller. That should be done from views.

/application/core/MY_Controller.php
Code:
class MY_Controller extends CI_Controller {
  function __construct()
  {
    parent::__construct();
  }

  //this will be available in all of your controllers now
  function universal_method()
  {
    return 'hello';
  }
}

now one of your controllers (extends MY_Controller)
/application/controllers/something.php
Code:
class Something extends MY_Controller {
  function __construct()
  {
    parent::__construct();
  }

  function show_message()
  {
    //access the method we defined in MY_Controller
    $data['message'] = $this->universal_message(); //now is 'hello'
    $this->load->view('some_view', $data);
  }
}

View
/application/views/some_view.php
Code:
<?php echo "Message is: $message"; ?>

access via url:
http://yoursite.com/something/show_message
