I have an Event class in Laravel as Controller class. Here is the namespace.
namespace App\Http\Controllers\Admin;
This is the class starting code and constructor.
class EventController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('auth');
}
And here is the function name and definition
function generateBarcodeNumber() {
$number = mt_rand(1000000000, 9999999999); // better than rand()
// call the same function if the barcode exists already
if (barcodeNumberExists($number)) {
return generateBarcodeNumber();
}
// otherwise, it's valid and can be used
return $number;
}
function barcodeNumberExists($number) {
// query the database and return a boolean
// for instance, it might look like this in Laravel
return User::whereBarcodeNumber($number)->exists();
}
I am calling this function in another function using $this
keyword as
$event->slug_str = $this->generateBarcodeNumber();
And this is the error:
Call to undefined function App\Http\Controllers\Admin\barcodeNumberExists()
Thanks!
