Get variables created in MY_Controller?

[eluser]chefnelone[/eluser]
hello

I created MY_Controller and defined some variable in it. Now, I don't know how to recover these variables from another controller which is extended to MY_Controller.

MY_Controller.php

Code:

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

class  MY_Controller extends Controller{

    function __construct(){  
      parent::__construct();
      define('COMPANY_EMAIL','[email protected]');
      $this->data['company_email']='[email protected]';
    }

}

another_controller.php

Code:

<?php  if (! defined('BASEPATH')) exit('No direct script access');

class Another_controller extends MY_Controller {
   function index(){
      $data['company_email']= //what's in here to get the value of 'company_email' defined in MY_Controller.php
      $this->load->view('index', $data);
   }
}

Make them class properties:

Code:

class  MY_Controller extends Controller{

  protected $company_email = '[email protected]';

Then in your extended class:

Code:

function index()
{
  echo $this->company_email;
}

Although in this case where you have to deal with 'global config' settings, you might be better off putting it in the config array or load it from the database.

It did't work. I get a blank page. If I remove the word 'protected' it runs fine, but I can't get the value of $company_email though;

Code:

class  MY_Controller extends Controller{

  $company_email = '[email protected]';//I remove 'protected' word to avoid blank page

extended class:

Code:

function index()
{
  $company_email = $this->company_email;
  $this->firephp->log( $company_email ); //this is line 278
}

then I get this error message:

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: index::$company_email

Filename: controllers/index.php

Line Number: 278

Your constructor is wrong CodeIgniter's core is PHP4
When you extend the MY_Controller then you can use PHP5 constructor.

Code:

class  MY_Controller extends Controller{

    function __construct(){  
      parent::__construct(); <--- WRONG! should be parent::Controller();
      define('COMPANY_EMAIL','[email protected]');
      $this->data['company_email']='[email protected]';
    }

}

ok, I think the constructor is ok now?
How do I get the value of $company_email from others controllers?

this is still not working

Code:

function index()
{
  $company_email = $this->company_email;
  $this->firephp->log( $company_email ); //this is line 278
}

gives me the error:

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: index::$company_email

Filename: controllers/index.php

Line Number: 278

If you use PHP4 try this:

Code:

class  MY_Controller extends Controller{

  var $company_email = '[email protected]';

I get the same error message:
Message: Undefined variable: company_email

Show us your entire code. I can't guess what's going wrong.

I get this error:

Code:

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: company_email

Filename: controllers/mycontroller.php

Line Number: 5

if I run this code:

application/libraries/MY_Controller.php

Code:

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

    class  MY_Controller extends Controller{
    
        function __construct(){
        
        parent::Controller();

        
          $company_email = '[email protected]';
        
        }

}

application/controller/mycontroller.php

Code:

<?php
class Mycontroller extends MY_Controller {

    function index(){
        $data['company_email'] = $company_email; //this is line 5
        $this->load->view('myview', $data);
    }
    

}

application/views/myview.php

Code:

<?php echo $company_email; ?>

[eluser]n0xie[/eluser]

Code:

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

    class  MY_Controller extends Controller{

        //php5
        protected $company_email = '[email protected]';    
        //php4
        var $company_email = '[email protected]';    

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

}
