can anyone give me a quick hand with namespaces and the UserFrosting environment?
To explain my issue, I'm using TCPDF to create a PDF document from data within UserFrosting. I've created a custom class, MyPDF, in the UserFrosting namespace so I can create a PDF within the UF namespace by typing $pdf = new MyPDF(blahblah); and that works fine.
The issue is with the MyPDF class itself - I need to be able to reference config vars from UF and don't know how I can do that - i.e.:
namespace UserFrosting;
class MyPDF extends \TCPDF_TCPDF {
public function Header() {
$image_location = $this->_app->config('upload.path')
How can I access config from within MyPDF? :?:
I've tried:
class MyPDF extends \TCPDF_TCPDF {
public function Header() {
$ufapp = new UFModel();
$image_location = $ufapp->config('upload.path')
... but no dice. I'm getting this error:
Cannot instantiate abstract class UserFrosting\UFModel
$app is just the global instance of UserFrosting that the entire application runs on. Since UserFrosting extends Slim\Slim, you can access it statically using the getInstance() method:
$app = UserFrosting::getInstance();
A better way, though, would be to actually pass $app into your MyPDF constructor. However, depending on your situation and where else you are using MyPDF, that might be more difficult.
