Hi Guys,
hope this is the right place to post,
I have an issue when trying to load a model from within the class constructor, it doesn't throw any errors but just gives me a blank page.
Am i doing something incorrectly?
Code:
function __construct()
{
parent::__construct();
$this->load->model('user_model');
}Any help greatly appreciated!

Have you checked the apache error log for PHP errors?

You need to get the CodeIgniter super-object first...
Code:
function __construct()
{
parent::__construct();
// get CI Object instance
$this->ci =& get_instance();
// then load using that instance
$this->ci->load->model('user_model');
}From the user guide:
Quote:Note: You'll notice that the above get_instance() function is being passed by reference:
$CI =& get_instance();
This is very important. Assigning by reference allows you to use the original CodeIgniter object rather than creating a copy of it.

If he is loading the model from the controller he doe's not need to use the CI Superobject!
If he trying to load it in a library etc then yes he will need the CI Superobject.

Have you already checked to make sure you named the model correctly? I've been known to forget to correctly name the model controller before.
IE
[code]
<?php
// application/models/user_model.php
class User_model extends CI_Model {
// constructor/methods/etc
}
?>

Here is a tip for all new users:
Code:
// use this at the top of all your controllers libraries and models.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
// not just this. With this they can view your scripts!
<?php
// Also do not use the PHP closing tag ?> This causes problems with white space.
// use this at the bottom.
/* End of file your_name.php */
/* Location: ./application/directory/file_name.php */InsiteFX
