How can i pass variables into a constructor of a model

ie.

class Car extends Model
{
public Car($params)
{
echo $params…..
..
. .
. }

}

Controller{

$this->load->model(‘car’, $params);

}

I have not found a way to this yet. I have to hack around it.

When you actually call the model function, that’s when.

// in the controller
$this->load->model('car');

echo $this->car->get_year($car_id); 

edit: Darn, reading Crafter’s response makes me realize I completely blew you question. Sorry, I misunderstood, just ignore the above post

You can’t.

The CI loader controls the instancing of your model , and makes no allowances for contructor parms.
See system.libraries/Loader.php

function model($model, $name = '', $db_conn = FALSE)
{
  :
                $CI->$name = new $model();
  :
} 

So your workaround is the only way for now.

PHP does not support strict types, so the point of constructor variable is lost somewhat in any case. It’s just pure convenience that saves you the overhaed of an additional class method invocation that you gain with PHP.
