I created a public static function in a controller and I need to access a class property which is set on the constructor. I normally use $this->something to access such class properties, but this time, I got this error:
Using
$thiswhen not in object context
Here's the code:
public static function PayExecute() {
$paymentId = Input::get('paymentId');
$PayerID = Input::get('PayerID');
$cont = $this->apiContext;
}
You need $apiContext be declared as static property, and you need use static of self keyword. Something like this:
class YourController extends BaseController
{
private static $apiContext = '';
public static function PayExecute()
{
$paymentId = Input::get('paymentId');
$PayerID = Input::get('PayerID');
$cont = static::$apiContext;
}
}
BTW: Be aware about fact that static is late static binding.
You cannot use "$this" in static methods. You do have access to "self::" though, but remember that you cannot access methods / properties that require the current class to be instanciated.
The source of this problem is the wrong instantiation of the Excel class.
Check your controller.
Wrong: use Maatwebsite\Excel\Excel;
Correct: use Maatwebsite\Excel\Facades\Excel;
In my case, I had a non-static controller function (so public function myFunc instead of public static myFunc), but I forgot a line where I was calling the function statically (like MyController::myFunc).
Removing this line fixed the error.
Moral of the story: when your function uses $this->something, do not call the function statically :)
kindly use self:: instead of $this-> if you are calling to the function which refers to the same function
public static function PayExecute() {
$paymentId = Input::get('paymentId');
$PayerID = Input::get('PayerID');
$cont = self::apiContext;
}
you have to create new instance and then can access its property
public static function PayExecute() {
$paymentId = Input::get('paymentId');
$PayerID = Input::get('PayerID');
$cont = (new static)->apiContext;
}
