sending data to library outside the array

[eluser]Renato Tavares[/eluser]
Whenever I create my own library is necessary to invoke it through an array? Let me explain:

In my library I have to pass only a code of 13 digits every time I call. In the documentation there is only examples of arrays, to work around that I am using the following syntax:

Controller calling the library:

Code:

[other things....]

$object = 'SW449086657BR';
$this->load->library('correios', array($object));
$data = $this->correios->result;
$this->load->view('actions/tracking', $data);

[other things....]

receiving data from controller in library

Code:

public function __construct($object) {

        $object = strtoupper($object[0]);

        if (preg_match('/^[a-zA-Z]{2}[0-9]{9}[a-zA-Z]{2}$/', $object)) {
            $this->search($object);
        } else {
            $this->result['erro'] = 'Objeto inválido';
        }
    }
[other things....]

I did not think this the most elegant solution, it is possible to improve?

I tried to pass off an array and did not work

I know the question may sound stupid but have tried in various ways and it did not work.

I'm using WAMP, maybe it my environment.

Without knowing your full library, can you NOT run your constructor check in the library, but rather direct in a function, like this:

Code:

[other things....]
$this->load->library('correios');
$data = $this->correios->result('SW449086657BR');
$this->load->view('actions/tracking', $data);
[other things....]

And your library

Code:

public function result($object) {
        if (preg_match('/^[a-zA-Z]{2}[0-9]{9}[a-zA-Z]{2}$/', strtoupper($object))) {
            //do something
        } else {
           //do something else
        }
}
[other things....]
