cakephp: access a variable in same controller but different function

Question

i wish to access a variable in cakephp which is global in scope - that is it is in same controller but different function. code:

homeController.php

    public function opauth_complete() {
    //global $facebook_data;
    $this->facebook_data = $this->data;
     debug($this->facebook_data); // returns data
    $this->redirect(array('controller' => 'home', 
                          'action' => 'user_home'));
}
public function user_home()
{
   // i wish to use $facebook_data here.
debug($this->facebook_data); // returns null

}

how do i implement this without using session?

you can store it in session

class HomeController extends Controller {        

    public function opauth_complete() {
      //assign the value
      $this->Session->write("facebook_data", $this->data);
     debug($this->facebook_data); // returns data
      $this->redirect(array('controller' => 'home', 
                          'action' => 'user_home'));
    }
    public function user_home() {
       //read from session
    debug($this->Session->read("facebook_data")); // returns data
    }
...

is there a way to do it without session?

Sudhir Bastakoti Over a year ago

@z22 well, i dont think so, because you are redirecting to other function, data in your local variable ($this->facebook_data) will not be available after redirect.

actually i tried it with session also but it still returns null, do i need to define the session helper?

Sudhir Bastakoti Over a year ago

yes you need to include Session Component in your Controller, if not already added in AppController, like using var $components = array('Session');

App::uses('AppController', 'Controller');

class UsersController extends AppController {

   private $FbData = array();

   public function opauth_complete() {
      $this->FbData = $this->data;
   }

   public function user_home(){
      debug($this->FbData); 
   }
}
