Global Variable? - Hasan Al-Haddad - 09-23-2018
Hello,
i'm new here and i find it is hard to find an answer at google due to my lacks of grammar or i don't even know what i'm gonna search. I've been thinking this over and over and also with practices but i got nothing. so, i want to ask everybody in this forum about this "global variable or not" thing.
i have a controller, i called it A_Controller and it is look like this:
PHP Code:
class A_Controller extends CI_Controller {
var $global = 0;
public function __construct(){
parent::__construct();
}
public function setGlobal($value){
$this->global = $value;
}
public function index(){
echo $this->global;
}
}
what i want to approach is, when i access /A_Controller/setGlobal/1000 the global variable is set. and i want to see its value at /A_Controller/index. but, i always got the global is 0.

Hi,
This is not working because the controller is reinitialized on the second call.
For this to work you need to use something to keep the value of $global like session or a variable in your view.
Or returning index in your setGlobal should work.
PHP Code:
class A_Controller extends CI_Controller {
var $global = 0;
public function __construct(){
parent::__construct();
}
public function setGlobal($value){
$this->global = $value;
$this->index();
}
public function index(){
echo $this->global;
}
}

If you need this like a global then use the static keyword.
PHP Code:
class A_Controller extends CI_Controller {
protected static $global = 0;
public function __construct(){
parent::__construct();
}
public function setGlobal($value){
self::$global = $value;
$this->index();
}
public function index(){
echo self$global;
}
}
