Question

I have two models, first one is dependent on the second one, and I need to call methods from the second one in the first one’s constructor.

So far I have this:

user

class User extends CI_Model {

    protected $_attributes = array();

    function __construct() {
        parent::__construct();
        $this->load->model('musers');
        foreach($this->musers->GetProfile() as $key => $val) {
            $this->_attributes[$key] = $val;
        }
    }

    function __set($key, $val) {
        return $this->_attributes[$key] = $val;
    }

    function __get($key) {
        return $this->_attributes[$key];
    }
}

I have put this model in the autoload config file and here’s what I get:

A PHP Error was encountered
Severity: Notice
Message: Undefined index: load
Filename: models/user.php
Line Number: 20

Fatal error: Call to a member function model() on a non-object in  path\to\models\user.php on line 9

There’s also something strange – the first error (notice) refers to line return $this->_attributes[$key]; while it surely should reference line $this->load->model('musers');.

I have tried loading model musers in autoload before the user model, but nothing helps. I have tried searching for this, but could not formulate the query well, I’m sure there are solutions to my problem.

As I understand this is because the constructor of the second model is called before CodeIgniter manages to load the loader class itself, but that’s pretty odd.

Try:

function __construct() {
    parent::__construct();
    $CI =& get_instance();
    $CI->load->model("musers", "musers");
    foreach($CI->musers->GetProfile() as $key => $val) {
        ......
}
