Loading Models, order

[eluser]nthvision[/eluser]
PHP throws me an "undefined property" error if I do the following....

Code:

function __construct()
{

parent::__construct();

$this->load->library('pagination');
$this->load->model('admin_testimonials_model');

/*to HERE -->>*/
$this->load->model('admin_model');

/*MOVE FROM below HERE*/
$this->load->model('admin_testimonials_config_model');


if(!$this->admin_model->validate_session())
  {
   die('you do not have permission');
  }
else {
  
  //load required models

  //initialize variables
  $this->data['change_settings'] = FALSE;
  $this->data['atleast_one_required_field'] = TRUE;
  $this->data['testimonials_p_p_error'] = FALSE;
}

can anyone help?

We need a bit more information in order to know where the problem is. I don't see anything wrong with that code. Can you post more and/or the exact error message?

sure, here it is.
...this post relates back to the other one you replied to.. its the same code, but I found two different bugs... the order in which I load the models effects which ones CI lets me use, as for the other ones I have to use the $CI super object to get it to work.

Code:

<?php
class Testimonials extends CI_Controller
{

public $data = array();
/*============*/
// constructor
/*============*/
function __construct()
{
parent::__construct();

//load libraries
$this->load->library('pagination');
//load required models
$this->load->model('admin/admin_model');
$this->load->model('admin/testimonials_model');
$this->load->model('admin/testimonials_config_model');


if(!$this->admin_model->validate_session())
  {
   die('you do not have permission');
  }
else {
  


  //initialize variables
  $this->data['change_settings'] = FALSE;
  $this->data['atleast_one_required_field'] = TRUE;
  $this->data['testimonials_p_p_error'] = FALSE;
}



}
