Accessing a Property Created in Another Library - El Forum - 08-01-2008

I have a library that I want to access session data without explicitly passing it in, I'm using a custom session class (although this shouldn't really play in much), I'm having the following issue..

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Pages::$session

Filename: libraries/Themer.php

Line Number: 21

Pages is the controller I'm running this from.


My Hooks File (I explicitly run sess_run), session doesn't auto-load and this part "works"

Code:
$hook['post_controller_constructor'][] = array(
                                    'class'    => 'Session',
                                    'function' => 'sess_run',
                                    'filename' => 'Session.php',
                                    'filepath' => 'libraries'
                                    );

Library Code
Code:
12 class Session {
13
14    /*
15    |--------------------------------------------------------------------------
16    | Constructor
17    |--------------------------------------------------------------------------
18    */
19    function __construct()
20    {    
21        $this->CI =& get_instance();
22        log_message('debug', 'AE_MemSession Class Initialized');
23                
23        $this->CI->load->model('aes', 'aes');
24                
25        if($this->CI->config->item('sess_match_useragent'))
26        {
27            //
29        }
30        else
31        {
32            //
33        }
34    }
35    
36    public function test()
37    {
38        echo 'WEE';
39    }

Other Library Trying to Access Property...
Code:
19    public function generate_header()
20    {
21        $this->CI->session->test(); // PROBLEM HERE
22    }

What am I missing? And, what would be the most efficient OO-Correct way to do this (previously I was using $_SESSION which had the benefit of being available everywhere.)

Your Session object doesn't appear to be assigned to the controller so you will get that error.

You could add $this->CI->session =& $this; in the Session library constuctor after get_instance();
