How to access a variable in a PHP class that is set by another function? Codeigniter

Question

I have this code here in PHP using Codeigniter framework, I can't seem to get my head around class variables in this code seems completely different to C++.

I was wondering how I can get a local variable in one class (function) method to another class method.

But not passing them as variables as I have to use a redirect function instead which cannot take variables.

The variable I want to have accessible is $record_id , i tried making it public etc does not like it.

class Submit extends CI_Controller {

function send_data()
{
        $record_id = $this->submit_model->create_record($completedstaffrows, $completedeventrows);

                        if ($record_id == FALSE)
                        {
                            echo "Failed to add to database";
                        }

                        //Submittal to database was successful
                        else
                        {

                            redirect('submit/success');
                        }
                        return;
                    }

This is the function that I want to have access the $record_id

public function success()
{

$page['page'] = 'success';
$page['record'] = $record_id;
$this->load->view('template', $page );


}

Remember - I cannot pass this as a variable to the other function as I need to use a redirect so that my URL will not screw up. Thanks

Cheers!

use codeigniter's tiny feature called Flashdata which allows you to have temorarily store data between requests.

so your code would be

function send data{
$this->session->set_flashdata('recordid', $recordid);
}

function success{
 $recordid =  $this->session->flashdata('recordid');
}

got it ?

class Submit extends CI_Controller {

    private $record_id=false;

    public function __construct(){
         if(isset($_SESSION['record_id'])){
              $this->record_id = $_SESSION['record_id'];
         }
    }

    public function send_data(){
        $this->record_id = $this->submit_model->create_record($completedstaffrows, $completedeventrows);
        $_SESSION['record_id'] = $this->record_id;
        if ($this->record_id == FALSE){
            echo "Failed to add to database";
        }
        else{
            redirect('submit/success');
        }
        return;
    }
    public function success(){

         $page['page'] = 'success';
         $page['record'] = $this->record_id;
         $this->load->view('template', $page );
    }
}

it's not gonna get $this->record_id == false at success() function()?, because I suppose when a redirect is made, we reload the controller again, but it will go to success() method with $this->record_id placed with a false value due to the new instance for the class.
