[quote author="Derek Allard" date="1266268882"]ok, good - now let's keep working.

Code:

$this->load->model('Model_name');

$file_name = "Derek";
$file_type = "jpg";
$username  = "derek.allard";

$this->Model_name->save_image($file_name); // what does this line look like to get 3 vars inserted?

[/quote]

in controllers :

Code:

$file_name = $image_data['file_name'];
$file_type = "jpg";
$username = "Derek.Allard";
$vars = array('file_name'=>$file_name, 'file_type'=>$file_type, 'username' => $username);

in Models :

Code:

function test($vars){
  echo $vars['file_name'];
  echo $vars['file_type'];
  echo $vars['username'];
}

Thanks Derek,, now I know... :-)
