Passing parameters through an extended library class?

[eluser]Wayne Smallman[/eluser]
Hi guys!

I'm building PDF functionality into an application via FPDF, and all is (almost) working fine.

And to make the FPDF truly useful, I've made it a globally available library. However, I need to pass parameters to the class, which isn't going according to plan.

Code:

function FPDF($orientation='P', $unit='mm', $size='A4') {...

Which I'm extending...

Code:

class Export extends FPDF {

And calling via a controller method...

Code:

$this->load->library('invoices/export', array('orientation' => 'L', 'unit' => 'mm', 'size' => 'A4'));

All of which works in so far as actually calling the library, but not when passing the parameters.

Any ideas how I get that to work?

Load your library the same as you have shown, but make sure your extended class controller's construct function includes something to handle a parameters array.

Code:

class Export extends FPDF {

    public function __construct($params)
    {
        parent::__construct($params['orientation'], $params['unit'], $params['size']);
    }

    ...
}

You should also ideally have some additional code to make sure that the $params array will always contain three default values if one or more of them was omitted during the load process.

I'll give that a try later on today and see how things go.
