Setting variables to be used controller wide. - El Forum - 06-19-2012
[eluser]uber_n00b[/eluser]
I want to setup a variable to be used by various functions in my controller. I have viewed one of the posts on here that offered a few suggestions but it was dealing with strings and not arrays.
How can I make $timezone_drop; available to all functions in my class/controller?
Code:
$timezone_drop = array(
'' => 'Select Timezone',
1 => 'Eastern',
2 => 'Central',
3 => 'Mountain',
4 => 'Pacific',
5 => 'Alaskan',
6 => 'Hawaiian',
);I have tried placing it in my construct function
Code:
function __construct()
{
parent::__construct();
$timezone_drop = array(
'' => 'Select Timezone',
1 => 'Eastern',
2 => 'Central',
3 => 'Mountain',
4 => 'Pacific',
5 => 'Alaskan',
6 => 'Hawaiian',
);
}
function index(){ $this->data['timezone'] = $timezone_drop; }index() will throw an error saying $timezone_drop is undefined however if I place the variable declaration in index() it works fine.
Please help.
Thanks!

The contructor is the right place. Just write
Code:
$this->timezone_drop = array();
// instead of:
$timezone_drop = array();In your methods use the same way:
Code:
$my_array = $this->timezone_drop;Setting variables to be used controller wide. - El Forum - 06-19-2012

Thanks for the reply LuckyFella - I had tried that as well previously. This is the error I receive.
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: timezone_drop
Filename: controllers/company.php
Line Number: 7

PHP likes its variables declared before using them.
Code:
class Something extends CI_Controller {
//Declare the property
public $timezone_drop = array();
function __construct()
{
parent::__construct();
$this->timezone_drop = array(
'' => 'Select Timezone',
1 => 'Eastern',
2 => 'Central',
3 => 'Mountain',
4 => 'Pacific',
5 => 'Alaskan',
6 => 'Hawaiian',
);
}
function index()
{
$this->data['timezone'] = $this->timezone_drop; //although, its already available throughout your controller as $this->timezone_drop, so not sure why you are assigning it to another variable
}

Thank you for the help - it has been a long day and I made a stupid mistake - I was doing $this->$printer_drop as opposed to $this->printer_drop!
Thanks again.

CroNIX - I assign it to another variable so I can pass $data[] to my view and use it to build a dropdown...Does that still not make sense?

You can just use $this->timezone_drop directly in your view without explicitly passing it, since it's a class property and globally available to anything from within that controller. No need for taking up extra memory within a separate variable.

CroNiX showed you how to do it above
Code:
class Something extends CI_Controller {
//Declare the property
public $timezone_drop = array();
function __construct()
{
parent::__construct();
$this->timezone_drop = array(
'' => 'Select Timezone',
1 => 'Eastern',
2 => 'Central',
3 => 'Mountain',
4 => 'Pacific',
5 => 'Alaskan',
6 => 'Hawaiian',
);
}
function index()
{
$this->data['timezone'] = $this->timezone_drop; //although, its already available throughout your controller as $this->timezone_drop, so not sure why you are assigning it to another variable
// this will make it global to all your controllers and views. So now you do not need to pass it
$this->load->vars($this->data);
}

I understand that InsiteFX.
CroNIX will give that a try in my view. Thanks again for the help.
